Embodiment Construction

[0010] figure 1 , figure 2 Embodiments of the present invention are collectively described.

[0011] The invention includes: 1) detailed research and analysis of stratum conditions; 2) accurate calculation of the settlement of the whole site; 3) partition scheme design; 4) whole-process information construction; Subsidence after elimination.

[0012] Technical solution of the present invention is:

[0013] According to geological survey data, site backfill height, and ground treatment technical requirements, calculate the foundation soil settlement of the entire site, and analyze uneven settlement conditions: according to post-construction settlement requirements and shallow survey (manual drilling, static penetration, etc.) data Carry out foundation soil treatment divisions. Determine the construction settlement that should be completed in each division according to the post-construction settlement requirements.

[0014] The precise partition size of the soft foundation ...

Abstract

The invention discloses a soft foundation treatment to eliminating non-uniform sedimentation, and it is characterized by: firstly dividing built-up area exactly according the data which is obtained by the rapid exploration means on site and the calculated settlement; using the fast dynamic dewatering consolidation process to forming a hard shell with certain thickness and high density on the soil layer in the dealing category. Its beneficial effects are: it eliminates non-uniform sedimentation in different parts of one field basically during the process of soft foundation construction, ensures the non-uniform sedimentation of ground foundation completed rapidly in construction period, prevents the engineering problems such as the ground deformation, buildings cracking caused by difference sedimentation after construction period.

Description

Technical field: [0001] The invention relates to a kind of soft soil foundation treatment where buildings require uneven settlement (differential settlement) of the foundation soil of the site, especially the rapid elimination of unevenness when the ground conditions of the site change greatly and the building is very sensitive to uneven settlement Settlement soft foundation treatment method. Background technique: [0002] The soft soil foundation treatment method that quickly eliminates the uniform settlement of the foundation soil has a good application prospect. In order to develop land resources for economic construction in our country and even in the world's sea islands and coastal countries, thousands of hectares of land are reclaimed from the sea every year. These new lands are located in various types of topography and original depositional conditions. The nature and thickness of soft soil, the nature and thickness of filling (blown) soil, and land reclamation metho...
