Embodiment Construction

[0019] A construction method for treating weak foundations by adopting the reverse method, the construction process steps are as follows:

[0020] 1. Preparation. Before the construction of the project, collect geological data according to the site conditions, types, grades, and characteristics where it is located, and master the foundation bearing capacity value (F K ), combined with the requirements of the engineering superstructure load on the foundation, determine the depth and scope of the weak soil layer treatment.

[0021] 2. Construction of the main project. Under the condition of knowing the original foundation soil layer, the foundation and part of the main structure shall be constructed first, and the number of layers to be constructed shall be based on the original foundation bearing capacity (F K ) as the basis, generally the main structure is capped on the second or third floor, and the foundation treatment construction is cut into. Specifically, it can bear t...

Abstract

A technology for treating soft ground by reverse construction order features that the foundation and part of main structure of a building is first built up and when the load on ground reaches its original bearing power the ground is grouted by pressure pouring while the structure of building is constructed. Its advantages are short constructino period and simple operation.

Description

1. Technical field [0001] The invention belongs to building construction technology, and relates to an inversion method for treating weak ground. 2. Background technology [0002] Tens of thousands of feet of tall buildings rise from the ground, and any building will be built on the foundation. As the cradle of the building, the foundation plays a pivotal role in the entire building structure. Regardless of whether it is an industrial building or a civil building, all the loads are transmitted from the foundation to the foundation, and the size and bearing capacity of the foundation are determined by the type and physical and mechanical properties of the foundation soil. The occurrence of construction accidents is mostly related to foundation problems, especially in areas with complex filling of furnace ash, vertical and horizontal ditches, and complex geological conditions. Often due to poor consideration in survey, design, and construction, or changes in the environment an...
