A Reinforcement Method of Cast-in-situ Lightweight Foam Concrete Based on Bolt Support

Abstract

The invention discloses a cast-in-situ light foam concrete reinforcing method based on anchor bolt support. The cast-in-situ light foam concrete reinforcing method based on anchor bolt support is used for reinforcing roadbeds, side slopes and foundation ditches. Firstly, anchor rods are arranged on original soil foundations of the road roadbeds, the side slopes and the foundation ditches, and each anchor bolt is partially inserted into the original soil foundation and is tightly combined with the original soil foundation; then, light foam concrete is poured into the soil foundations, provided with the anchor bolts in advance, to be reinforced to reinforce the original soil foundations. The cast-in-situ light foam concrete reinforcing method based on anchor bolt support can be applied to civil engineering like building foundation pitch backfill and support in cities with insufficient land supply, ring expressway reorganization and expansion extension or expressway reorganization and expansion, and has the advantages of saving land, being capable of achieving uniform deformation of the foam concrete and the original soil, and ensuring that light foam concrete stably takes effect and is long in service life, simple in structure and good in technical effect, and has very important significance in engineering construction like building foundation pitch support in cities with insufficient land supply and high and steep expressway reorganization and expansion.

Description

Technical field: [0001] The invention relates to the technical field of reinforcement structure design and application of roadbeds, slopes, foundation pits, etc., and in particular provides a reinforcement method for cast-in-situ lightweight foam concrete based on bolt support. Background technique: [0002] In the prior art, bubble-mixed lightweight soil (light soil for short) appears in the engineering field, which is a new type of lightweight soil filling material developed in the field of civil engineering in recent years. Proportional addition of curing agent, water and air bubbles is formed after thorough mixing and stirring. Its main features are low bulk density, thermal insulation, self-supporting after curing, and fluidity during construction. Lightweight soil plays a unique role in soft foundation treatment, road widening, backfilling of abutment abutments, and solving road frost heaving and slurrying. However, due to the special environment, light soil cannot p...

Problems solved by technology

However, due to the special environment, the light soil cannot play its role

For example, the stability of foundation pit support, or the reinforcement of foundation pit is limited by the surrounding environment, high and steep roadbed support, etc. In addition, there are problems such as poor cohesion when lightweight foam concrete is combined with the original soil.
