Abstract
Based on a cast-in-situ light foam concrete reinforcement means for bolt support, for the reinforcing of roadbed, side slope, foundation ditch.First on original soil matrix of highway subgrade, side slope, foundation ditch, arrange anchor pole, each anchor pole has locally to be inserted in original soil matrix combines closely with original soil matrix; Then, waiting to reinforce and the original soil matrix place arranging anchor pole in advance builds light foam concrete to reinforce original soil matrix.The present invention can be applicable to land used anxiety the supporting of urban architecture pit backfill, around city at a high speed or the civil engineering such as expressway reconstruction and extension project, its topmost advantage is saved the area, it can realize foam concrete and original soil and be consistent and be out of shape; It can realize stable onset, long service life, and structure is simple, and technique effect is excellent.The present invention is of great significance engineering construction tools such as the urban architecture pattern foundation pit supporting structure of land used anxiety, the steep roadbed reorganization and expansion of height of expressway.
Description
Technical field:
The present invention relates to the ruggedized construction design and devdlop technical field of roadbed, side slope, foundation ditch etc., specifically provide a kind of cast-in-situ light foam concrete reinforcement means based on bolt support.
Background technology:
In prior art, there is air bubble mix light-textured soil (abbreviation light soil) in engineering field, it is a kind of novel light fill material in recent years developed in civil works field, it adds curing compound, water and bubble according to a certain percentage in raw material soil (or foam concrete), formed after abundant mix and blend.Its main feature be can support oneself after low unit weight, heat-insulation and heat-preservation, solidification, tool flowable when constructing.Light soil bankets at treatment of soft foundation, road widening project, Abutment Back and has unique effect in solving road frost boil etc.But due in particular circumstances, light soil can not play its effect.As being subject to surrounding enviroment restriction, high steep roadbed supporting etc. in pattern foundation pit supporting structure stability or foundation ditch strengthening, in addition, light foam concrete and original native associated working, have problems such as there is bad adhesion.
Therefore, people expect to obtain the excellent cast-in-situ light foam concrete reinforcement means based on bolt support of a kind of technique effect.
Summary of the invention:
The object of this invention is to provide the cast-in-situ light foam concrete reinforcement means based on bolt support that a kind of technique effect is excellent.
A kind of cast-in-situ light foam concrete reinforcement means based on bolt support of the present invention, for the reinforcing of highway subgrade, side slope, foundation ditch; It is characterized in that: first on original soil matrix of highway subgrade, side slope, foundation ditch, arrange anchor pole, each anchor pole has locally to be inserted in original soil matrix combines closely with original soil matrix;
Then, waiting to reinforce and the original soil matrix place arranging anchor pole in advance builds light foam concrete to reinforce original soil matrix.
The described cast-in-situ light foam concrete reinforcement means based on bolt support, is characterized in that: described light foam concrete specifically uses these raw materials of cementitious material, industrial residue, sand, blowing agent to mix formation.
The anchor pole arranged at original soil matrix place in advance before building light foam concrete meets following requirement: anchor pole is specially anyhow in conjunction with layout, a common formation reinforced frame; The anchor pole arranged in advance as simultaneously with original soil matrix and the connecting framework that is simultaneously combined of the light foam concrete of after-pouring work.
Cast-in-situ light foam concrete reinforcement means based on bolt support provided by the present invention can be applicable to the urban architecture pit backfill supporting, around city at a high speed or the civil engineering such as expressway reconstruction and extension project of land used anxiety, its topmost advantage is saved the area, and it can realize foam concrete and original soil and be consistent and be out of shape; It can realize stable onset, long service life, and structure is simple, and technique effect is excellent.
The height steep roadbed reorganization and expansion of the urban architecture pattern foundation pit supporting structure that the present invention is land used anxiety, expressway provides the reinforcement means of a kind of economy, safety; The present invention is of great significance engineering construction tools such as the urban architecture pattern foundation pit supporting structure of land used anxiety, the steep roadbed reorganization and expansion of height of expressway.
Accompanying drawing illustrates:
Fig. 1 is the cast-in-situ light foam concrete reinforcement means principle schematic based on bolt support.
Detailed description of the invention:
In accompanying drawing 1, the implication representated by each Reference numeral is explained as follows: original soil matrix 1, light foam concrete 2, anchor pole 3.
Embodiment 1
Based on a cast-in-situ light foam concrete reinforcement means for bolt support, for the reinforcing of highway subgrade, side slope, foundation ditch; Its key takeaway is: first in original soil matrix 1 of highway subgrade, side slope, foundation ditch, arrange anchor pole 3, and each anchor pole 3 has locally to be inserted in original soil matrix 1 combines closely with original soil matrix 1; Then, waiting to reinforce and original soil matrix 1 place arranging anchor pole 3 in advance builds light foam concrete 2 to reinforce original soil matrix 1.
Described based in the cast-in-situ light foam concrete reinforcement means of bolt support, the proportionate relationship mixing during described light foam concrete 2 specifically uses these raw materials of cementitious material, industrial residue, sand, blowing agent is conventionally formed.
The anchor pole 3 arranged at original soil matrix place 1 in advance before building light foam concrete meets following requirement: anchor pole 3 is specially anyhow in conjunction with layout, a common formation reinforced frame; The anchor pole 3 arranged in advance as simultaneously with original soil matrix 1 and the connecting framework that is simultaneously combined of the light foam concrete 2 of after-pouring work.
The cast-in-situ light foam concrete reinforcement means based on bolt support that the present embodiment provides can be applicable to the urban architecture pit backfill supporting, around city at a high speed or the civil engineering such as expressway reconstruction and extension project of land used anxiety, its topmost advantage is saved the area, and it can realize light foam concrete 2 and be consistent with original soil matrix 1 and be out of shape; It can realize stable onset, long service life, and structure is simple, and technique effect is excellent.
The height steep roadbed reorganization and expansion of the urban architecture pattern foundation pit supporting structure that the present embodiment is land used anxiety, expressway provides the reinforcement means of a kind of economy, safety; The present embodiment is of great significance engineering construction tools such as the urban architecture pattern foundation pit supporting structure of land used anxiety, the steep roadbed reorganization and expansion of height of expressway.
