Abstract

The invention relates to a removal blasting method for buildings, in particular to a blasting method for frame buildings. The method adopts the modes of blasting different spans at the same time, single support point release and inclined guide blasting, mainly solves the technical problems of insufficient restrict to falling and extension of the front disassembly and assembly in application of current methods and generation of obvious recoil negative effect to the rearmost section support surface, and greatly improves the comprehensive competitive capability of adopting the blasting technology.

Description

A kind of blasting method of framework building
Technical field:
The present invention relates to the demolition blasting method of building, particularly a kind of blasting method of framework building.
Background technology:
The blasting demolishing method of available frame building adopts mainly that the single hop orientation is toppled, multistage unidirectional disintegrate by cross and multistage complete in to methods such as the original place cave in.These methods all discharge with striding with quick-fried, many fulcrums, the positive quick-fried pattern of guide.Though these methods help to improve the efficient of demolishing buildings work, also there is following defective:
1, leading portion disintegration structure body slump abduction is lacked enough constraints;
2, back segment supporting surface is produced remarkable recoil negative effect.
As mentioned above, the blasting method of existing framework building is bigger to the influence basin of surrounding environment, sometimes even work the mischief.Therefore, demand proposing new improvement project urgently.
Summary of the invention:
The purpose of this invention is to provide a kind of blasting method of framework building, in the use of the existing method of solution leading portion disintegration structure body slump abduction is lacked enough constraints, and the technical problem that back segment supporting surface is produced remarkable recoil negative effect, under the severe rugged environment condition that urban renewal, dismounting industry face, promoted the comprehensive competitive power that adopts blasting technique greatly.
For solving the problems of the technologies described above, the present invention is achieved in that
A kind of blasting method of framework building is characterized in that: its adopts different striding with quick-fried, single fulcrum to discharge, and obliquely leads quick-fried pattern.
The blasting method of described framework building is characterized in that: certain the bight column by frame construction building begins to detonate, and obliquely leads quick-friedly by row, is different striding with quick-fried with coming into line quick-fried every root post, is the diagonally opposing corner column until back segment; During wherein any one section explosion, the every bit of its back segment strong point all is single fulcrums in forward is arranged.
The blasting method of described framework building is characterized in that: this forward is arranged as vertical/horizontally-arranged row.
Description of drawings:
Fig. 1 is the inventive method detonating network network layout schematic diagram.
Among the figure:
Grid shows the column site;
Connect in the oblique line section of showing;
Numeral 1-15 represents to lead quick-fried order;
Dotted line shows the design protection side.
The specific embodiment:
The invention provides a kind of based on different stride with quick-fried, single fulcrum discharge, the oblique blasting method of leading the framework building of quick-fried pattern, this method can produce two-way in length and breadth constraint to the leading portion slump abduction of disintegrating, also can make last section and only have single strong point, the recoil effect that is produced significantly reduces.
See also Fig. 1, it is a kind of specific implementation process of the inventive method.As shown in the figure: it is begun to detonate by certain bight column of frame construction building, oblique lead by row quick-fried, all non-with striding (being different striding) with coming into line quick-fried every root post with quick-fried, be the diagonally opposing corner column until back segment.During wherein any one section (or claiming tiltedly row) explosion, the every bit of its back segment strong point all is single fulcrums in forward (vertical/horizontal stroke) is arranged.
By implementing the inventive method, its mechanics optimization characteristics are:
(1) implements the inventive method and reduced the excessive effect of forward abduction component gathering that the many fulcrums of existing technology discharge;
(2) implement the inventive method when arbitrary fulcrum explosion slump, all be subjected to the abduction constraint of longitudinal and transverse two-way connection beam;
(3) implement the inventive method, because back segment support post is single column (corner post), the recoil effect is limited to greatly.Example is comprehensively counted a tree names and shown: adopt one-sided (design protection direction) safe distance of present technique, from original 5 meters are reduced in 3 meters.Be exactly the progress of these " 2 meters ", under the severe rugged environment condition that urban renewal, dismounting industry face, promoted the comprehensive competitive power that adopts blasting technique greatly.
The core of the inventive method mainly is the quick-fried program of leading that has changed, optimized explosion execution network, realizes by the blast working network of design.Do not change the use equipment, do not change the mode of operations, any constructor who possesses dynamiter's qualification all can easily understand and grasp, and does not need additional training.

Claims (3)

1. the blasting method of a framework building is characterized in that: its adopts different striding with quick-fried, single fulcrum to discharge, and obliquely leads quick-fried pattern.
2. the blasting method of framework building according to claim 1 is characterized in that: certain the bight column by frame construction building begins to detonate, and obliquely leads quick-friedly by row, is different striding with quick-fried with coming into line quick-fried every root post, is the diagonally opposing corner column until back segment; During wherein any one section explosion, the every bit of its back segment strong point all is single fulcrums in forward is arranged.
3. the blasting method of framework building according to claim 2 is characterized in that: this forward is arranged as vertical/horizontally-arranged row.
