Construction method of ikebana socket water stop curtain for dual spindle soil-cement stirring mill

Abstract

The invention relates to a construction method for a water-seal curtain being crosswise sleeved on a biaxial soil cement agitator. The construction method comprises the following steps: first step, a field is leveled; second step, a biaxial soil cement agitator is positioned; third step, agitation is performed for the first time and an agitator head is descended to the depth of a pile; fourth step, agitation is performed for the second time and the agitator head is ascended to the top of the pile; fifth step, agitation is performed for the third time and the agitator head is descended, and the third step is repeated; sixth step, agitation is performed for the fourth time and the agitator head is ascended, and the fourth step is repeated to form a first columnar induration; seventh step, a mortar feeding tube is cleaned; eighth step, the agitator is advanced for two pile positions; ninth step, the third, the fourth, the fifth and the sixth steps are repeated to form a second columnar induration; tenth step, the seventh step is repeated; eleventh step, the mortar is dropped back for a pile position, then the third and the fourth steps are repeated, crosswise sleeve joint is performed to the two columnar indurations, and a branching between the two columnar indurations is eliminated; twelfth step, the seventh step is repeated; thirteenth step, the agitator is advanced for three pile positions, then the fourth, the fifth and the sixth steps are repeated, and the construction of a fourth columnar induration is carried out; fourteenth step, the tenth, the eleventh, the twelfth and the thirteenth steps are repeated in sequence, and non-branching water-seal curtain is continually accomplished. The method greatly enhances the integrity and the barrier property of the water-seal curtain, saves space, and saves the construction cost.

Description

technical field [0001] The invention relates to a method for setting a water-stop curtain on the periphery of a foundation pit, in particular to a construction method for a water-stop curtain by using a conventional two-axis cement-soil mixer for flower arrangement socketing. Background technique [0002] In order to ensure the smooth construction of the foundation pit and the safety of surrounding buildings, water-stop curtains are usually arranged around the foundation pit to prevent groundwater outside the foundation pit from flowing into the foundation pit. The water-stop curtain is connected by cement-soil mixing piles formed by mixing cement slurry and soil. At present, the cement-soil mixers used in the construction of cement-soil mixing piles are mostly double-shaft cement-soil mixers. The two cement-soil mixing piles formed by the construction form a columnar consolidation body. In order to prevent the water outside the foundation pit from flowing into the foundatio...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the problem of splits between two columnar consolidation bodies produced during the construction of water-stop curtains by existing twin-shaft cement-soil mixers, thereby providing a water-stop with flower-arranged sockets for twin-shaft cement-soil mixers The curtain construction method improves the anti-seepage function of the water-stop curtain and ensures the safety of foundation pit construction and surrounding buildings
