Embodiment Construction

[0038] The following is attached Figure 1-3 The application is described in further detail.

[0039] The embodiment of the present application discloses a construction structure of seepage cofferdam design bottom-sealing concrete. refer to figure 1 with figure 2, seepage cofferdam design back cover concrete construction structure includes a cofferdam body 1, the cofferdam body 1 is a cubic steel casing 11 arranged vertically, and an anti-seepage mechanism 2 and a positioning mechanism 3 are arranged inside the cubic steel casing 11.

[0040] refer to figure 1 , The cubic steel casing 11 comprises four casing plates 12, and the casing plates 12 are connected end to end in sequence. A protruding portion 13 is installed on the casing plate 12 . The protruding part 13 is a strip-shaped steel plate, the two long sides of the steel plate are bent towards the same side of the steel plate, and the bending angle is an acute angle, and the two long sides of the protruding part 13...

Abstract

The invention relates to a bottom sealing concrete construction structure for water seepage cofferdam design. The bottom sealing concrete construction structure comprises a cofferdam body, wherein the cofferdam body is a cubic steel sleeve box which is vertically arranged; a concrete bottom sealing layer is poured at the lower end of the inner side of the cubic steel sleeve box; an anti-seepage mechanism is arranged at the lower end of the cofferdam body; the anti-seepage mechanism comprises an anti-seepage coiled material, an anti-seepage frame and an anti-seepage water stop plate; the anti-seepage coiled material is arranged in the circumferential direction of the inner side wall of the lower end of the cubic steel sleeve box; the anti-seepage frame comprises a fixing part, a connecting part and a frame body; the fixing part is fixedly arranged on the inner side wall of the cubic steel sleeve box; the connecting part is detachably and fixedly arranged on the lower side of the fixing part; the anti-seepage frame is fixedly arranged on the lower side of the connecting part; the anti-seepage water stop plate is fixedly arranged on the frame body; and the top surface of the concrete bottom sealing layer is higher than the anti-seepage water stop plate and lower than the fixing part. The bottom sealing concrete construction structure has the effects that the fixing part and the connecting part are separated, so that the cofferdam body is separated from the connecting part, and the cofferdam body can be conveniently disassembled.

Description

technical field [0001] The present application relates to the field of steel cofferdam construction technology, in particular to a design and method for the construction of a seepage cofferdam back cover concrete structure. Background technique [0002] Steel cofferdams in bridge foundation construction are usually used as water retaining structures for underwater caps. After the construction of the steel cofferdam is completed, the back-sealing concrete is poured. After the back-sealing concrete has a certain strength, the accumulated water in the cofferdam is pumped out to form a dry working environment. Operators enter the cofferdam to bind steel bars and construct caps and bridge piers. After the back-sealing concrete is poured in the steel cofferdam, since the steel cofferdam and the back-sealing concrete are different materials, there is a significant interface, and the two have different temperature deformation coefficients, resulting in differences in the bonding for...
