Embodiment Construction

[0043] The following is attached Figure 1-5 The application is described in further detail.

[0044] The embodiment of the present application discloses the construction method of the concrete anti-seepage wall, and the construction method of the concrete anti-seepage wall comprises the following steps:

[0045] S1, refer to image 3 , Use site leveling machinery to level the area where holes will be excavated.

[0046] S2, refer to image 3 , After the site leveling is completed, measure and draw lines on the construction ground according to the final design drawings of the concrete cut-off wall. The entire concrete cut-off wall will be constructed in strict accordance with the markings on the construction ground. The equipment enters the construction area and a mud purification system is built nearby.

[0047] S3, refer to image 3 , after all the equipment is ready, use large-scale excavating machinery to excavate the slotted hole 1 according to the marking line on th...

Abstract

The invention relates to a concrete diaphragm wall construction method. The concrete diaphragm wall construction method comprises the following steps that S1, site leveling mechanical equipment is used for conducting site leveling operation on an area where holes are to be excavated and formed; S2, surveying and setting out are conducted, specifically, surveying and marking out are conducted on the construction ground according to a design drawing of a concrete diaphragm wall; S3, groove-shaped holes are excavated in the construction ground through large excavating mechanical equipment; S4, before concrete is poured into the groove-shaped holes, groove-forming columns are downwards put into the groove-shaped holes, the concrete is poured after the groove-forming columns are put down, and after the concrete is firmly formed, the groove-forming columns are taken out of formed concrete wall sections; S5, the step S3 and the step S4 are continuously and sequentially repeated, holes are formed beside the formed concrete wall sections, concrete is poured, and a concrete continuous wall is finally formed by each concrete wall section; S6, maintenance is conducted; and S7, quality inspection is conducted. The concrete diaphragm wall construction method has the effect of improving the connecting firmness of the two adjacent concrete wall sections.

Description

technical field [0001] The present application relates to the technical field of concrete cutoff walls, in particular to a construction method for concrete cutoff walls. Background technique [0002] Concrete anti-seepage wall, longitudinal section of the vertical wall, the wall extends along the dam body, continuously creates holes in the loose permeable foundation, solidifies the wall with mud, and pours concrete into the hole to build a wall-shaped anti-seepage building , it is one of the main measures for vertical anti-seepage treatment of hydraulic structures such as gates and dams in loose permeable foundations. [0003] The anti-seepage wall is built in sections. A round hole or slot hole is poured with concrete to form a wall section. Many wall sections are connected to form a whole wall. If the bottom is embedded in bedrock or relatively impermeable strata to a certain depth, the seepage flow in the foundation can be cut off or reduced, which plays an important rol...
