Example Embodiment

[0018]The present invention is further described below with reference to the accompanying drawings and examples.

[0019]Such asfigure 1 withfigure 2 As shown, the present invention has different depth foundation pits on both sides of the operation subway, and the subway C is provided with deep basis pit B and shallow base pit A, respectively, with the light bulk pit A is high. The boundary line is divided into shallow zone 1 above the deep shallow division line and below the deep shallow boundary line or less;

[0020]The shallow base pit A and the shallow zone 1 of the deep foundation pit B perform soil excavation, and the earth-blocking blocks of the shallow foundation pit A and the shallow zone 1 of the deep foundation pit B shall be sealed. The block, layered, relative excavation from the direction away from the subway C adjacent to the subway C;

[0021]The deep-layer excavation of the deep foundation pit B is turned on, and the deep layer zone is performed in the depth region of the s...

Abstract

The invention discloses an earth excavation method for foundation pit groups with different depths on two sides of an operation subway. A deep foundation pit and a shallow foundation pit are arranged on the two sides of the subway respectively. The earth excavation method comprises the following steps that the bottom elevation of the shallow foundation pit serves as a depth boundary, and the deep foundation pit is divided into a shallow area higher than the depth boundary and a deep area lower than the depth boundary; earth excavation is carried out on the shallow foundation pit and the shallow area of the deep foundation pit, earth in the shallow area of the shallow foundation pit and the shallow area of the deep foundation pit is horizontally partitioned, and block-by-block, layered and relative excavation is carried out in the direction from the position away from the subway to the position close to the subway; and earth excavation is carried out on the deep area of the deep foundation pit, horizontal partitioning is carried out on the deep area with the shallow area as the standard, and block-by-block and layered excavation is carried out in the direction from the position away from the subway to the position close to the subway. The earth excavation method solves the technical problem of lateral deformation caused by unbalanced excavation on the two sides of the subway.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an earthwork excavation method for foundation pit groups with different depths on both sides of an operating subway. Background technique [0002] Under the background of the increasingly scarce urban land resources and the promotion of urban development by rail transit, improving the charm of hub nodes is the key to increasing the value of land along the line. The station space is no longer simply used as a mobile space connecting the station itself and the city, but should afford A character that embodies the character of the city. As a result, a high-end business district with a station-city integration complex centered on public transport hubs and stations has gradually been derived. With the acceleration of the urbanization process, there are more and more construction projects along the subway line and with the subway. The excavation of the foundation pit of the const...
