Description
Technical field
The present invention relates to one kind can promote site operation quality and constructing structure globality, reduces barricade waste residue movement hardly possible
Degree improves the construction method that wall carries on the back the retaining wall ecology dismounting structure of soil body stability, belongs to field of civil engineering, is suitable for gear
Cob wall Demolition Construction engineering.
Background technique
Retaining wall is commonly used for the construction works such as highway engineering, hydraulic engineering, architectural engineering as a kind of supporting construction
In, to prevent soil deformation unstability and structure from destroying.Due to the influence of the defects of detail design or natural environment, retaining wall
It will appear the diseases such as aging, cracking in use, seriously threaten the safety of structure, need in time to tear retaining wall open
Except construction.In existing retaining wall Demolishing Technology mostly based on the strengths method for dismounting such as direct explosion, easily there is wall back soil
Body or barricade, which collapse, waits dangerous situations, and there are security risks.
Has a kind of concrete barricade controlling method for dismounting in the prior art, comprising: by digging concrete barricade wall back under excavator
The cubic metre of earth and stone of side, it is ensured that concrete barricade is higher than the cubic metre of earth and stone, is successively cut by sequence from top to bottom using concrete cutting machine
The concrete barricade is cut, described excavate carries out cut portion to hook concrete operation, and cut portion is hooked to cubic metre of earth and stone side, cutting
The layer height of the concrete barricade clears the cutting part positioned at cubic metre of earth and stone side with depending on the difference in height of concrete barricade and the cubic metre of earth and stone
Point.The relatively existing demolition blasting of this method or the energetically method of demolition reduction, are cut concrete barricade by way of cutting
It is removed at fritter, the lower shoveling cubic meter of stone and dismounting wall circulation construction.The construction method can avoid concrete barricade in demolishing process
In collapse, preferably realization retaining wall is removed safely, but earthwork evacuation amount is big, clears construction cost height, and the method does not relate to
And the technologies such as the movement of retaining wall waste residue, wall back soil body stability promotion.
In conclusion existing construction method achieves preferable effect in suitable operating condition, but in lifting construction works
The construction technology of globality, reduction barricade waste residue movement difficulty etc. is not perfect.It can in consideration of it, urgently inventing one kind at present
To promote site operation quality and constructing structure globality, reduction barricade waste residue movement difficulty, improve wall back soil body stability
