Description

Technical Field

[0001] This utility model relates to the field of guide wall technology, and more specifically to a guide wall structure for an anti-seepage wall. Background Technology

[0002] The guide wall is a key structure in the construction of the anti-seepage wall, used to ensure the accuracy of the trenching position and the stability of the construction. In the existing technology, the guide wall is set in "L" shape or inverted "L" shape. The precast steel guide wall is usually inverted "L" shape. The precast steel guide wall generally includes two baffles and a connecting rod. The connecting rod is vertically fixed between the opposite side walls of the two baffles. The baffles and connecting rod of the above-mentioned precast steel guide wall are usually fixed by welding, so they are difficult to remove and inconvenient to store and transport.

[0003] The existing prefabricated guide wall for seepage prevention wall disclosed in CN218148286U opens the slot by removing the sealing parts, allowing the insert block to be pulled out of the slot, thereby detaching the connecting rod from the baffle, which facilitates storage and transportation. However, this utility model also has the following problems: the soft soil wall on the outside of the guide wall is loose, which can easily lead to the guide wall tilting and shifting, resulting in weak stability of the guide wall and affecting the quality of the seepage prevention wall pouring in the later stage. Therefore, this utility model proposes a seepage prevention wall guide wall structure. Utility Model Content
