Introduction of Qingyuan Qingxin Zheng Jiang Building Construction Project?

What is a wide seam gravity dam? For this type of gravity dam with wide joints, how do construction enterprises carry out project construction and what is the basic construction technology? In order to let people in the construction industry have an intuitive understanding of the wide-joint gravity dam, Zhong Da has consulted and compiled the following information about the gravity dam, which is basically introduced as follows:

First of all, we understand the basic definition of wide-seam gravity dam:

The slotted gravity dam widens the middle of the transverse joints of each dam section of the solid gravity dam into a hollow gravity dam.

Basic advantages of wide-joint gravity dam;

① Because of the existence of wide joints, the dam bottom area is small, the uplift pressure is obviously reduced, and the upstream slope is gentle, so the upstream water can be used to increase the stability, so the concrete quantity of the dam body can be saved by about10% ~ 20% compared with the solid gravity dam;

(2) wide joints increase the heat dissipation surface, which is beneficial to the concrete temperature control during construction;

(3) After the dam is left with a wide seam, it is convenient to observe and inspect the dam, and if necessary, it can also carry out maintenance and foundation treatment in the wide seam.

Disadvantages are:

(1) template workload is large, and the unit price of concrete is increased;

(2) construction diversion is a little inconvenient;

(3) In cold areas, heat preservation measures must be taken.
