Method for carrying out settlement of underground wall structure by means of high-pressure water guns

Abstract

The invention discloses a method for carrying out settlement of an underground wall structure by means of high-pressure water guns. The method for carrying out the settlement of the underground wall structure by means of the high-pressure water guns comprises the following steps that (a) a field is leveled, and setting-out is conducted for positioning; (b) the underground wall structure is poured in place; (c) a total station is installed; (d) pre-preparation for the settlement of the underground wall structure is conducted; (e) the high-pressure water guns are arranged; (f) settlement of the first stage of the underground wall structure is conducted by means of the high-pressure water guns; (g) the second stage of the underground wall structure is poured in place; and (h) the underground wall structure is reinforced through grouting. According to the method for carrying out the settlement of the underground wall structure by means of the high-pressure water guns, an annular slurry groove is formed in the periphery of the underground wall structure, so that a soil body supporting the underground wall structure collapses in order, and accordingly the underground wall structure sinks slowly under the action of the self-weight, and construction of an underground building wall and a building enclosure is achieved; the method for carrying out the settlement of the underground wall structure by means of the high-pressure water guns has the advantages of being high in construction speed and high in working efficiency.

Description

technical field [0001] The invention relates to the construction of walls and enclosure structures of underground buildings in the technical field of civil engineering foundation engineering, in particular to a method for subsidence of underground wall structures by high-pressure water guns. Background technique [0002] In the foundation construction of the construction site, the construction of the underground building enclosure structure must be implemented first before the foundation pit is excavated, and then the precipitation and excavation are implemented in the foundation pit. After the excavation is completed, the construction of the underground wall structure can be implemented. Because the construction procedure is complicated, cost is high, and efficiency is low, it is not favored; adopting the overall settlement construction method of the underground wall structure is exactly the construction method that the enclosure structure and the underground wall structure ...

[0002] In the foundation construction of the construction site, the construction of the underground building enclosure structure must be implemented first before the foundation pit is excavated, and then the precipitation and excavation are implemented in the foundation pit. After the excavation is completed, the construction of the underground wall structure can be implemented. Because the construction procedure is complicated, cost is high, and efficiency is low, it is not favored; adopting the overall settlement construction method of the underground wall structure is exactly the construction method that the enclosure structure and the underground wall structure are combined into one. The prior art underground wall structure The construction of the underground wall structure is to locate the prefabricated or cast-in-place underground wall structure on the ground, and excavate the soil at the internal support part of the underground wall structure, that is, the excavation settlement method, so that the underground wall structure relies on the gravity of the structure itself to overcome the surrounding After the frictional resis...
