Novel underground structure foundation bottom plate waterproof guide wall construction method

Abstract

The invention discloses a novel underground structure foundation bottom plate waterproof guide wall construction method. The novel underground structure foundation bottom plate waterproof guide wall construction method comprises the following specific steps: first, a center line of a waterproof guide wall is paid off on a cushion layer and marked; second, hollow plate walls are manufactured, arrayed and sectioned; third, fixing bars are embedded in the cushion layer at intervals, and the positions of the fixing bars correspond to hollow plate holes in each hollow plate wall; fourth, the hollowplate walls are mounted, and plate body inverted-T-shaped parts and plate body U-shaped parts are mounted in an aligned mode; fifth, the mounting accuracy is rechecked, and the hollow plate holes arepoured with mortar; sixth, mounted spliced joints of the hollow plate walls are subjected to joint pointing; and seventh, fertilizer grooves in the outer sides of the hollow plate walls are backfilled with soil. The hollow plate walls are mounted, the plate body inverted-T-shaped parts and the plate body U-shaped parts are spliced, thus mounting can be convenient and quick, and the construction period is saved; and through the mode of arranging the fixing bars on a bottom plate, when mounted, the hollow plate walls can be fixed in the lateral direction, and during soil backfill construction of the fertilizer grooves, the hollow plate walls are prevented from being toppled.

Description

technical field [0001] The invention belongs to the field of underground building construction, and in particular relates to a construction method for a novel base plate waterproof guide wall of an underground structure. Background technique [0002] With the continuous and rapid development of my country's economy and the acceleration of urbanization, the construction of housing construction and municipal engineering is huge. In the construction of underground structure engineering, the quality control of waterproof engineering construction is particularly critical. Generally, before the waterproof construction of the base plate of the underground structure, the waterproof guide wall of the base plate needs to be constructed first. At present, the waterproof guide wall of the foundation base plate generally adopts the method of brick masonry + plastering, and then the waterproof membrane is laid outside; the traditional method has slow construction speed and labor input.
