Embodiment

[0034] Such as figure 1 As shown, a new type of prefabricated two-wall-in-one foundation pit enclosure system and its reverse method, the new foundation pit enclosure system is composed of an enclosure structure combined with a support system. The enclosure structure is composed of a new type of water-stop centrifugal pile 1. The new type of water-stop centrifugal pile 1 is connected by using a guide groove 7 to connect with each other, and a concrete top beam 6 is arranged on the top of the pile. figure 2 As shown; the support system adopts the building roof 2 poured in sections to ensure the stability of the foundation pit; the building roof 2 is connected to the new water-stop centrifugal pile 1 through the embedded steel bar connector 5 .

[0035] A new type of prefabricated two-wall-in-one foundation pit enclosure system and its inversion method involved in the present invention adopt side pile machine 8 for construction, and the specific steps are as follows:

Abstract

The invention relates to a novel prefabricated two-wall-in-one foundation pit enclosure system and a reverse building method thereof. The novel prefabricated two-wall-in-one foundation pit enclosure system consists of an enclosure structure and a support system. The enclosure structure is formed by novel water stop centrifugal piles, and the novel water stop centrifugal piles are connected by adopting manners of jointing guide grooves and arranging concrete pressure top beams on the pile tops; the support system adopts building top plates poured section by section; and the support system is connected to the novel water stop centrifugal piles by embedded steel bar connectors. Compared with the existing pipe rack-type foundation pit enclosure systems, the novel prefabricated two-wall-in-one foundation pit enclosure system has the advantages of short construction period, no pollution, low noise, high stability of the enclosure structure, low construction cost, small influences on the surrounding and the like.

Description

technical field [0001] The invention relates to a new type of prefabricated two-wall-in-one foundation pit enclosure system and its reverse construction method, which are mainly used in the fields of foundation pit enclosure and prevention of earth displacement of municipal buildings such as pipe corridors. Background technique [0002] Land resources in modern cities are extremely scarce, and the construction of municipal infrastructure is increasingly restricted by land resources, municipal planning, urban landscape and environmental protection. It is imminent to comprehensively place various cables and pipelines. The underground municipal comprehensive pipe gallery, also known as the common ditch, is to set up underground trenches for various public utilities to place cables and pipes. Underground comprehensive pipe gallery is a relatively advanced form of infrastructure pipe network layout in the world at present, it is the trend and trend of urban construction and urban...
