Embodiment Construction

[0031] In order to make the purpose, technical solutions and beneficial effects of the present invention more clear, the embodiments of the present invention will be described below in conjunction with the accompanying drawings. features can be combined arbitrarily with each other.

[0032] like Figure 1-2 As shown, a method for strengthening the foundation of an industrial factory building includes the original structural foundation beam 1, the original foundation cap 2 and the original immersed pipe pouring pile 3, the original structural foundation beam 1 is arranged on the original foundation cap 2, and the original immersed pipe pouring pile 3 is anchored on both sides of the bottom of the original foundation cap 2, which also includes a newly added concrete cap 4, a newly added steel pipe pile 5 and a newly added anchoring steel bar 6. The bottom of the newly added steel pipe pile 5 goes deep into the bearing layer, the newly added concrete cap 4 is erected on the top ...

Abstract

The invention relates to an industrial plant foundation strengthening method, belongs to the field of earthquake-proof strengthening technologies and discloses a foundation processing method. The method comprises the steps of using a newly-increased steel pipe pile and an upper newly-increased concrete bearing platform, fixedly connecting the newly-increased steel pipe pile and the upper newly-increased concrete bearing platform with a primary foundation bearing platform through steel bar anchors, and commonly bearing a newly-added layer structure, so that steadiness and safety of an added layer improving engineering are ensured; and the problems of personnel and property losses caused due to earthquake which is caused due to poor anti-seismic property of original houses in improvement of old plants are solved fundamentally.

Description

technical field [0001] The invention relates to a strengthening method, in particular to a method for strengthening the foundation of an industrial factory building, and belongs to the technical field of seismic strengthening. Background technique [0002] As we all know, the addition of floors inside the building does not occupy new land, saves investment, and can make full use of the existing building structure, especially widely used in the renovation of old factories. However, in the case of increasing the load of the superstructure, it is easy to cause insufficient bearing capacity of the foundation or uneven settlement, and it is necessary to strengthen the foundation of the factory building. Using new steel pipe pouring piles and concrete caps to share the anchoring connection with the original foundation caps can achieve a good reinforcement effect, and the construction quality is easier to control, and the technical and economic benefits are higher. In the technolo...
