Emergency plan for construction safety in rainy season

Model essay on emergency plan for construction safety in rainy season

In daily life or work and study, it is inevitable that some accidents will happen suddenly. In order to avoid the deterioration of the situation, it is often necessary to make emergency plans in advance according to specific conditions. So how to make a scientific emergency plan? The following is a sample essay on the emergency plan for construction safety in rainy season. Welcome to reading. I hope you will like it.

A, the overall requirements of the rain period construction

1, to ensure smooth information. Due to the uncertainty and suddenness of severe weather such as construction storm in rainy season, its damage degree is difficult to predict. It is necessary to strengthen the control and management of meteorological information, take effective safety measures in time, and strengthen prevention.

2. The comprehensiveness of protection. The construction site covers a wide range, including the safety protection of all parts and temporary facilities on site and the safety of all personnel. Therefore, when formulating safety measures, we must be comprehensive, meticulous and thoughtful, and we must not fail to do it because of trivial matters, leaving hidden dangers and bringing losses.

3. Scientific organizational construction. When preparing the construction organization design, fully consider the characteristics of rainy season construction, arrange the projects unsuitable for rainy season construction in advance or later, do a good job of interspersed working procedures, improve work efficiency and construction speed, and stop construction in case of heavy rain.

4, rapid response to prepare for flood control and disaster relief, construction in the rain period, all kinds of protective measures should be further strengthened. Ensure that the rescue and relief materials personnel are in place, and immediately start the emergency plan in case of danger.

Second, the rainy season construction safety preparation measures

1, arrange the work and rest time reasonably. In case of a strong storm, all operators should stop working and evacuate to a safe place.

2, do a good job of site drainage.

(1) Dangerous stones should be properly handled at the construction site in rainy season to prevent landslides and other disasters.

(2) In order to ensure the smooth road, the pavement should be hardened or paved with gravel, slag or other materials according to the actual situation, and raised and arched as required.

(3) Protection of raw materials, finished products and semi-finished products. Conduct a comprehensive inspection of the material warehouse on a regular basis and maintain it in time. The surrounding drainage is good, the wall foundation is firm, and the materials such as steel are stored with corresponding rainproof measures to ensure the quality and safety of materials.

(4) Set up continuous and unimpeded drainage facilities and emergency materials in strict accordance with flood control requirements, such as water pumps and related equipment, plastic sheets, linoleum and other materials.

Three, the key component rainy season construction safety measures.

1, foundation engineering.

Foundation engineering is greatly affected by rain, and if relevant preventive measures are not taken, it may have a serious impact on construction safety and building quality. Therefore, in the rain period construction should pay attention to the following points:

(1) When excavating foundation trench (pit) or pipe trench in rainy season, attention should be paid to slope stability. If necessary, you can slow down the slope of the edge or set up supports. The inspection and control of slope and support should be strengthened during construction; Support shall be provided for the excavated foundation trench (pit) or pipe trench; Excavation is mainly based on slow breaking, supplemented by support; Stop construction when the rainfall has a great impact.

(2) The working face of rain period construction should not be too large, and should be completed by stages, one by one. When the rainfall is heavy, large-scale earthwork construction should be stopped; After the foundation is dug to the elevation, it shall be accepted in time, and concrete cushion shall be poured; If the foundation is soaked by rain, necessary excavation and backfilling should be carried out to restore the bearing capacity of the foundation; Important or special projects should be completed before the rain period.

2, concrete engineering:

(1) The weather forecast should be grasped in time before the template isolation layer is painted to prevent the isolation layer from being washed away by rain;

(2) In case of heavy rain, stop pouring concrete and cover the poured parts. Cast-in-place concrete should be retained with several construction joints according to the structural conditions and possible considerations;

(3) During construction in the rain period, the determination of water content of coarse and fine aggregate of concrete should be strengthened, and the water consumption should be adjusted in time;

(4) Before large-scale concrete pouring, it is necessary to know the weather forecast for 2-3 days. Try to avoid the heavy rain. A large number of rain-proof materials should be prepared at the concrete pouring site to prevent sudden rain during pouring;

(5) Backfill soil supported by formwork should be compacted and padded, and check for subsidence after rain;

(6) When it rains, steel bars shall not be welded and butted. When in urgent need, rainproof measures should be taken or construction work should be moved indoors. Newly welded steel bar joints should be rain-proof to prevent the joints from suddenly cooling and brittle cracking, which will affect the building quality.

3, lifting engineering:

(1) The stacking place of components should be flat and solid, with good drainage around. It is forbidden to accumulate water and soak in the component stacking area to prevent the soil from sticking to the embedded parts;

(2) The tower crane subgrade must be higher than the natural ground 15cm, and it is forbidden to soak the subgrade in rain;

(3) When hoisting after rain, first check the stability of the crane itself, and then try hoisting after confirming that the safety of the crane itself has not been damaged by rain. Hoist the component to about 1m, and then hoist it after several times of stability.

(4) Rainy days may affect the sight of crane drivers. If the driver has no lifting experience in rainy days, stop lifting; Or ask an experienced driver to do it;

(5) When the construction is stopped, the hook of the tower crane should be retracted and close to the tower body, and no slings, building components and other objects should be left on the hook, so as to avoid these heavy objects being shaken by the wind, which may lead to the collapse of the tower crane in severe cases.

(6) Because the surface of the component and the hoisting rope are wet, the friction coefficient between the rope and the component is reduced, and serious quality and safety accidents such as component slipping may occur; At this time, more attention should be paid to hoisting work, and measures such as increasing the surface roughness of ropes and components can be taken when necessary to protect the safety of hoisting work;

(7) When hoisting in rainy days, the forbidden area on the ground should be expanded, and additional personnel should be sent for vigilance when necessary.

(8) Stop all lifting operations in strong wind or heavy rain with a wind force of 6 or above.

4. Rainproof and lightning protection of construction machinery and electricity utilization on the construction site:

(1) rainproof. All mechanical sheds should be set up and fastened to prevent rain. Mechanical and electrical equipment should be rain-proof and flood-proof, and can be closed with fortification awning or poncho. The mechanical installation position is slightly higher, and the surrounding drainage is better. Install grounding device. The leakage protection device of mobile switch box should be reliable and sensitive;

(2) Lightning protection. The rainy season is a season of frequent lightning. In order to prevent lightning accidents on the construction site, effective lightning protection devices must be installed on steel pipe scaffolding, tower cranes, material hoists and people and goods elevators. , lightning protection grounding resistance should not be greater than 10ω.

(3) electric shock prevention. The power consumption on the construction site must conform to the three-level distribution and two-level protection, and the three-level electrical box is repeatedly grounded, and the resistance is less than10Ω; Wires and cables shall be buried reasonably, and there shall be no aged or damaged cables; In case of stormy weather, professional electricians should be arranged to inspect the dormitory in safe voltage. When necessary, turn off the power immediately, and all employees must turn off the power of all equipment and tools before leaving work.

Four, the rain period construction safety precautions

1. Strengthen safety inspection and find problems in time. Regularly inspect the main building, scaffolding, construction electricity, small mechanical awning, temporary facilities and safety signs, find problems in time, eliminate them in time, and repair the damaged parts in time.

2, pay attention to the use of rain materials, to take treatment measures before use.

3, the storm should immediately stop outdoor construction work, personnel quickly evacuated to a safe place, at the same time, the whole site should decisively pull off the power supply.

4, strengthen the training and education of construction personnel, strengthen the study of common sense of safe construction in rainy season, and improve self-prevention ability and emergency response ability.
