Embodiment Construction

[0063] A method for synchronous construction adjacent to deep and shallow foundation pits, comprising the following steps:

[0064] (1) Measure the elevation of the site, verify the excavation depth of each part of the foundation pit, and remove the surface construction waste;

[0065] (2) Refer to the geotechnical engineering survey report to verify the location of underground obstacles. If there are any, the underground obstacles should be removed before construction to ensure the quality and continuity of the enclosure construction;

[0066] (3) Accurately set out the plane of the basement before construction, and check the plane distance between the outer wall and floor of the basement and the surrounding buildings and enclosure structures;

[0067] (Four)

[0068] (1) Referring to the geotechnical engineering investigation report, verify the location of the dark bank, excavate the bank soil and backfill it with plain fill, and compact it layer by layer;

[0069] (2) The c...

Abstract

The invention discloses an adjacent deep foundation trench and shallow foundation trench synchronous construction method. The adjacent deep and shallow foundation trench construction method comprises the steps that site elevation is measured, underground barrier positions are verified, and accurate setting out, Creek soil excavation, plain fill back filling, foundation pit support and the like are conducted on a basement plane before construction. The adjacent deep and shallow foundation trench construction method is convenient and is good in construction quality.

Description

technical field [0001] The invention relates to a synchronous construction technology adjacent to deep and shallow foundation pits. Background technique [0002] Adjacent to the construction of deep and shallow foundation pits has been a difficult problem in construction for a long time, and the construction quality is difficult to guarantee. Therefore, a construction method with good effect is urgently needed. Contents of the invention [0003] The object of the present invention is to provide a synchronous construction method adjacent to deep and shallow foundation pits with good construction quality. [0004] Technical solution of the present invention is: [0005] A synchronous construction method adjacent to deep and shallow foundation pits is characterized in that it includes the following steps: [0006] (1) Measure the elevation of the site, verify the excavation depth of each part of the foundation pit, and remove the surface construction waste; [0007] (2) Re...
