A construction method of water-stop curtain anti-seepage structure

Abstract

The invention relates to a waterproof curtain impervious structure and a construction method thereof. According to the waterproof curtain impervious structure, expansion bolts are arranged on two supporting piles which are located at the pervious positions of a waterproof curtain, horizontal steel bars are embedded into the positions closer to the outer sides of the supporting piles relative to the expansion bolts, the embedded horizontal steel bars need to meet the test requirements, split bolts are provided and connected with the expansion bolts in a welded mode, the split bolts are connected with the horizontal steel bars in an overlapped mode through a steel bar, vertical steel bars are bound with the horizontal steel bars to form a steel bar mesh, formworks are arranged on the periphery of the steel bar mesh in a supported mode, so that the expansion bolts are connected with the split bolts so as to tension a primary joist fixing formwork and a secondary joist fixing framework, and concrete is poured after a reinforcement measure is completed so as to form the waterproof curtain impervious structure. According to the waterproof curtain impervious structure and the construction method of the waterproof curtain impervious structure, the water seepage problem of the waterproof curtain can be solved rapidly, the problems existing in large-area water seepage treatment of the waterproof curtain when confined water is high in level and pressure are solved especially, the water-stopping and impervious effect is good, and the treatment speed is high.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to the water-stop curtain anti-seepage structure technology in the construction of deep foundation pits. Background technique [0002] With the emergence of super-large and super-high buildings, there are more and more super-large and super-deep foundation pits, and the water-stop curtain is a commonly used water-stop enclosure measure in the construction of deep foundation pits. When water seepage occurs in the water-stop curtain, the grouting process is usually used to quickly plug the leak point, or the steel wire mesh is hung in the leak area and then the concrete is sprayed to prevent the seepage of the curtain. However, when the pressurized water level outside the water-stop curtain is high, the water pressure is high, and water seepage occurs in a large area, the above-mentioned conventional methods cannot achieve a good water-stop and anti-seepage e...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a construction method for the anti-seepage structure of the water-stop curtain, which effectively solves the problem of large-area water seepage outside the water-stop curtain under the condition of high water level and high water pressure. The speed is fast, the water-stop and anti-seepage effect is good, and it can quickly solve the safety hazards of the foundation pit caused by the water seepage of the water-stop curtain
