Description
Technical field
The invention belongs to the demolition technique fields of reinforced concrete support in deep foundation pit support, more particularly, to a kind of reinforcing bar
Engineering method is cut and disassembled in concrete support mechanization.
Background technique
In Construction of Deep Excavation Engineering, reinforced concrete support dismounting belongs to the biggish part-to-item project of risk.It is right
In the dismounting of reinforced concrete support, more there are commonly pneumatic picks to abolish method and two kinds of demolition blasting method.The former speed of application is slow,
Noise is big, dust pollution is serious, and personnel's input amount is big, is affected to the occupational health of ambient enviroment and construction personnel.Afterwards
Although person's speed of application is very fast, the more difficult region suitable for surrounding enviroment complexity, certain local government departments are also expressly provided
" forbidding removing foundation pit support using blasting method in key area ".There is also public security departments to rendrock for demolition blasting method simultaneously
Dosage control is stringent, the examination & approval of demolition blasting and long flow path of putting on record, large-scale excavation beam explosive need to carry out multiple explosion and
So that the disadvantages of environmental risk is big.In recent years, unit in charge of construction always searches for a kind of efficient, safe and environment-friendly supporting removal side
Method, to adapt to, the current deep foundation pit construction duration is tight, surrounding enviroment are complicated, occupational health requires high, construction safety control is stringent etc.
Feature, and the complete technology of machine cuts is supported also to have been more and more widely used.
Summary of the invention
The purpose of the present invention is in view of the deficiency of the prior art, provide a kind of reinforced concrete support mechanization
Engineering method is cut and disassembled, it, which has the characteristics that can be reduced, removes that time, construction cost be lower and construction more environmental protection.
To achieve the goals above, the technical scheme adopted by the invention is that: a kind of reinforced concrete support mechanization is cut
Dismounting engineering method is cut, construction procedure is as follows:
A, it supports segment design: piecemeal being carried out to support system, is segmented and numbers in advance；
B, tool-type bracing members bracket assembles: tool-type steel bracket horizontal layout, according to hoisting machinery ability and operation half
Diameter situation determines that every piece of support cutting weight, the concrete support block weight after cutting are controlled in 1.5T-3T or so；
C, subsection hole-drilling prebored hole: is carried out to purlin and trestle large-mass member；
D, cutting machine is cut: being cut according to segmentation markers to reinforced concrete support section by mechanical cutter；
E, segmentation stay fork fortune: supporting section fork is transported to by lifting position using fork truck, and is laid with guidance tape at post-cast strip position；
F, supporting section entrucking outward transport is handled: after reinforced concrete support section passes through cutting construction to end, being applied by handling
Worker person uses two ends of wirerope bundled fixed supporting section, and lifts by crane, then by gas cutting personnel by concrete support single side side
Main reinforcement is cut off, and sling cart outward transport is then played.
Bracing members bracket is removed after the step e.
The mechanical cutter uses hydraulic disk cutting machine or chain saw cutting machine.
The invention has the advantages that compared with the prior art: 1, after constructing, it is smooth that cut surface is straight, without volume
Outer equating can be well protected permanent knot for the engineering that the concrete support in supporting construction is combined with permanent structure
The construction surface quality at structure position reduces the later period and repairs the whole labour of equating；2, mechanization support cutting compared to beam explosive and
The vibration that the method that pneumatic pick is removed generates is less, thus to the influence of ambient enviroment when reducing supporting removal；3, using machinery
Cutting machine cutting, construction noise is small, dust is few, reaches the requirement of construction site green construction.
Specific embodiment
As described below is only presently preferred embodiments of the present invention, is not intended to limit the scope of the present invention.
Embodiment 1: a kind of reinforced concrete support mechanization cutting disassembling engineering method, construction procedure are as follows:
A, it supports segment design: piecemeal being carried out to support system, is segmented and numbers in advance；It should be according to construction process and scene
Actual conditions carry out piecemeal to support system, are segmented and number in advance；According to the size of construction area, reasonable disposition construction machine
Tool and personnel.
B, tool-type bracing members bracket assembles: tool-type steel bracket horizontal layout, according to hoisting machinery ability and operation half
Diameter situation determines that every piece of support cutting weight, the concrete support block weight after cutting are controlled in 1.5T-3T or so；It is supporting
Bracing members bracket is arranged according to cutting drawing requirement in cutting position, guarantees that support construction is stablized when cutting；To the steel branch being arranged
Bracketing frame will check whether its connection is firm, and whether intensity, stability reach prescribed requirement.
C, subsection hole-drilling prebored hole: is carried out to purlin and trestle large-mass member；Drilling device uses high-speed boring machine, leads to
Drilling is crossed to allow loop wheel machine that there can be lifting point.
D, cutting machine is cut: being cut according to segmentation markers to reinforced concrete support section by mechanical cutter；Machine
Tool cutting machine uses hydraulic disk cutting machine or chain saw cutting machine, can not set to structure reserved opening or construction hole to be provided position
When setting bracing members bracket, fastener type steel pipe bent-frame bracing can be used, then cut；Since these region fork trucks can not be into
Enter, support cutting section answers the maximum limit weight of strict control hoisting machinery, and general control is in 1.5T -3T or so, crane
Tool can not local support, the purlin of lifting air compressor machine hand breaking can be used.
E, segmentation stay fork fortune: supporting section fork is transported to by lifting position using fork truck, and is laid with guidance tape at post-cast strip position；
After support cutting, supporting section fork is transported to by lifting position using fork truck, post-cast strip position is encountered and is laid with guidance tape, one section of fork fortune is hung
One section of fortune is forbidden to stack at one in the supported collection of segmentation dismounting.
F, supporting section entrucking outward transport is handled: after reinforced concrete support section passes through cutting construction to end, being applied by handling
Worker person uses two ends of wirerope bundled fixed supporting section, and lifts by crane, then by gas cutting personnel by concrete support single side side
Main reinforcement is cut off, and sling cart outward transport is then played.
Embodiment 2, embodiment 2 is roughly the same with 1 construction procedure of embodiment, the difference is that: it is right after step e
Bracing members bracket is removed, and is handled again the rubbish at scene after dismounting.
