Problems solved by technology

[0004] With regard to the above-mentioned related technologies, the inventor believes that the steel cages in this related technology are made by traditional manufacturing methods, that is, they are composed of multiple vertical and cylindrical main bars and steel bars welded to the outside of each main bar, and the karst geology The foundation is unstable, and it is easy to squeeze the steel cage, which will cause deformation of the steel cage and affect the strength of the foundation.

Embodiment Construction

[0038] The following is attached Figure 1-3 The application is described in further detail.

[0039] The embodiment of the present application discloses a steel cage for karst geology. refer to figure 1 , The reinforcement cage includes a reinforcement cage body 1, and the reinforcement cage body 1 is composed of a plurality of vertical and cylindrical main bars and a plurality of steel bars welded around each main bar. A plurality of connecting rods 2 are fixed by welding on the outer side of the reinforcement cage body 1 , and each connection rod 2 is consistent with the length direction of the reinforcement cage body 1 . Several reinforcing rods 3 are arranged on each connecting rod 2, and each reinforcing rod 3 is inserted into the rock and soil outside the reinforcement cage body 1, so that the reinforcement cage body 1 is supported, that is, the stability is improved.

[0040] refer to figure 1 with figure 2 One end of the reinforcement bar 3 close to the reinforc...

Abstract

The application relates to a reinforcement cage for karst geology and a ground reinforcement method for karst geology. Reinforcing rods, each of which is inserted into the rock and soil outside the reinforcement cage body. The application has the effects of strengthening the stability of the foundation and high construction efficiency.

Description

technical field [0001] The application relates to the field of building construction, in particular to a steel cage for karst geology and a foundation reinforcement method for karst geology. Background technique [0002] The karst area refers to the special landform formed by the long-term dissolution of soluble rocks such as limestone and dolomite by corrosive water; , the permeability is enhanced, and it is usually easy to cause problems such as insufficient bearing capacity of the foundation, collapse of the roof of the underlying karst cave, subsidence of the foundation, and uneven settlement of the foundation. [0003] The Chinese patent of CN108589718U discloses a kind of pile foundation construction method in karst area, comprising the steps of: utilizing rotary drill and percussion drill to carry out advanced drilling; In order to ensure the ultimate bearing capacity, the pile foundation is drilled, and the reinforcement cage is placed in the middle and bottom of th...
