Construction method of movable anchoring steel plate ground wall guide wall

Abstract

The invention relates to a construction method for a movable anchoring steel plate ground wall guide wall. The construction method comprises the following steps that (1) a ground fixing plate is arranged in advance and fixed; (2) an excavation groove used for lowering a soil retaining plate is excavated in the excavation direction of the preset ground wall; (3) a soil retaining plate is lowered into the excavated groove, the soil retaining plate is made to be tightly attached to the wall of the excavated groove, and the soil retaining plate is fixedly connected with the ground fixing plate; (4) the steps (1)-(3) are repeated, after the requirements are met, a ground wall groove is excavated along the pre-designed ground wall position, and after excavation is completed, a reinforcement cage is put down, and a ground wall is poured; and (5) removing the soil retaining plate and the ground fixing plate. The method is applied to foundation pit engineering, the movable anchoring steel plate ground wall guide wall is developed, the ground wall is rapidly excavated, and the method has important significance on rapid construction.

Description

technical field [0001] The invention belongs to the fields of foundation pit engineering and underground construction engineering, and in particular relates to a construction method for a movable anchoring steel plate ground wall guide wall. Background technique [0002] In the construction of underground engineering, the main way to guide and prevent landslides in the existing ground wall construction is the concrete guide wall, which is formed by excavating the guide wall groove, lowering the guide wall reinforcement cage, and pouring. The construction period is long and the ground Once the wall is complete it is discarded. It leads to waste of materials and prolongs the entire construction period. When urgent construction is required, it cannot meet the use requirements. Moreover, after the pouring of the concrete guide wall is completed, there may still be structural cracks leading to water leakage, which seriously affects the normal construction of the subsequent excav...

AI Technical Summary

Problems solved by technology

It leads to waste of materials and prolongs the entire construction period. When urgent construction is required, it cannot meet the use requirements.

Moreover, after the pouring of the concrete guide wall is completed, there may still be structural cracks leading to water leakage, which seriously affects the normal construction of the subsequent excavation ground wall

If the groundwater level needs to be controlled to excavate the trench, it will greatly increase the cost investment and time investment
