Problems solved by technology

With the development of cities in our country, the scope of urban areas continues to expand, but many cities have natural resources below them. The natural resource layer can be considered as the base layer of the far-field building. Coordinating between them has become a top priority, that is, how to ensure the long-term stability of the ground foundation and foundation structure after resource development, so there is an urgent need for a method / structure to ensure the long-term stability of the foundation for building construction

Embodiment Construction

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1-2 , a method for strengthening foundations for building construction, comprising the following construction steps: S1, for natural resources under the building area, such as coal, it is divided into a plurality of rectangular mining areas 1, coal pillars are left in the mining area, and the mining area 1 Inward direction ( figure 1 In the middle, left and right directions), it is divided into rectangular working face 2, and in the middle of the mining area, the figure 1 The mining area uphill 3 is arranged in the front and rear direction), and the working face 2 on the two wings of the mining area (both sides of the mining area uphill) is connected to the main shaft, auxiliary shaft, ventilation shaft, etc. of the mine, so as to realize transportation, pedestrians, ventilation, etc. ;

[0032] S2, in the stable rock formation in the u...

Abstract

A foundation reinforcing method for building construction comprises the steps that natural resources under a building area are divided into a plurality of rectangular mining areas, and the interior of each mining area is divided into a rectangular working face in the trend; a top drainage roadway is constructed above each working face along the trend, and layer-crossing drilling holes are respectively constructed to the ore bed of each working face from the top drainage roadway; working face stoping is carried out after gas extraction, in the stoping process, an extraction steel pipe is lengthened from the upper end, filling and supporting are carried out, and a filling strip is formed; filling the strip mined-out areas between the filling strips of the working face, and repeating the steps until the whole mining area is mined; in the construction process, building construction is normally conducted on the ground, resource recovery and ground construction are synchronously conducted and do not interfere with each other, and the foundation is stable after resource recovery.

Description

technical field [0001] The invention belongs to the field of municipal construction and relates to a foundation reinforcement method, in particular to a foundation reinforcement method for building construction. Background technique [0002] Municipal engineering refers to the establishment of various buildings, structures, equipment, etc. within the planning and construction scope of urban areas; various infrastructure constructions supporting urban life belong to the category of municipal engineering, such as common urban buildings, urban roads, bridges, subways, Underground pipelines, tunnels, rivers, rail transit and other projects. The foundation refers to the soil or rock mass supporting the foundation under the above-mentioned municipal buildings and structures. There are two types of natural foundations and artificial foundations. Natural foundations are natural soil layers that do not require human reinforcement, while artificial foundations require human reinforce...
