Description
Technical field
The invention belongs to anchor cable processing technology field, and in particular to anchor cable processing side in the range of a kind of foundation pit enclosure structure
Method.
Background technology
In the process of China's urban construction, with being on the increase for deep-foundation pit engineering, prestress anchorage cable is once used as civil engineering
Foundation pit enclosure structure construction a kind of economical and effective means and extensive use.Compared with other support technologies, anchor cable has valency
Lattice are cheap, construction is simple is ripe, speed is fast, it is safe and reliable, be not take up the advantages that main body construction work.Meanwhile face as one kind
When property supporting measure, anchor cable can not recycle after supporting disabler, forever buried together with the structures built in underground without
Method is taken out, and forms underground garbage, causes underground environmental pollution, pile foundation construction, excavation of foundation pit to adjacent plot, the municipal administration of surrounding
Construction, subway work, the long-term plan in city and sustainable development cause to seriously affect.Especially as the progressively hair of urban construction
Exhibition and the utilization of the underground space, originally foundation pit cable bolting become follow-up underground space construction especially foundation pit enclosure structure
The obstacle of construction, must be handled for the anchor cable constructed in advance, just can guarantee that the smooth implementation of foundation pit enclosure structure.
For the anchor cable process problem encountered in base pit engineering, generally use is such as during construction activity at present
Lower method is handled：1st, cutting machine imderwater cutting anchor cable is utilized；2nd, anchor cable is thrust using impact drill impulse force.
There are the following problems for above-mentioned anchor cable processing method：1st, existing building structure is abolished, quantities is larger, and it is difficult to coordinate；2、
Original geologic structure is destroyed, causes large area to cave in, backfill influences building enclosure construction quality；3rd, impact drill cannot be guaranteed hole
Verticality, and it is less efficient.So construction needs there are still notable unsatisfied urban construction, it would be highly desirable to exploitation more preferably anchor
Rope processing method.

Embodiment
With reference to specific embodiment, the present invention will be further described.It is to be understood that within the scope of the present invention, it is of the invention
Above-mentioned each technical characteristic and below（Such as embodiment）It can be mutually combined between each technical characteristic of middle specific descriptions, so that
Form new or preferable technical solution.As space is limited, not repeated them here.It is all to be realized based on the above of the present invention
Technology belong to the scope of the present invention.
Lead wall
A kind of working measure mode that wall is unit in charge of construction is led, first to be constructed before continuous wall trench underground and lead wall, it is to ensure to lead wall
Diaphram wall position is accurate and the key of grooving quality, in construction period, leads that wall often bears steel reinforcement cage, pour concrete is led
The effect of the static and dynamic loadings such as pipe, drilling machine, thus conscientiously must design and construct, the formal construction of diaphram wall could be carried out.
Diaphram wall should all set and lead wall, lead wall form have it is prefabricated and two kinds cast-in-place, it is cast-in-place lead wall shape have " L " type or
Inverted "L" shape, can select according to different soil properties.When soil layer property is preferable, inverted "L" shape can be selected, or even pre-manufactured steel leads wall, uses
" L " type leads wall, and should strengthen leading wall behind is backfilling and compacted work.Ground good location in top layer is led using simple form reinforced concrete
Wall；Wall is led using cast-in-place L-shaped reinforced concrete in the area of topsoil weakness.

Machine monitors deviation correcting device.
4）Run into anchor cable
Since anchor cable intensity is higher, chute forming machine is difficult to directly grab disconnected, pulls the generation in the hole that can cause to collapse by force, chute forming machine grab bucket exists
It cannot close to verify during fetching earth and there is anchor cable at this.
5）Installing rope of grabbing bucket saw, hydraulic tube connection
After tentatively anchor cable position is verified, anchor cable specific location is further verified using magnet, rope saw frame is quickly installed into
In scouring machine grab bucket, hydraulic oil pipe and the rope saw driving hydraulic oil pipe reserved in connection chute forming machine grab bucket.
6）Cut off anchor cable
Using restricting, sawing removes the characteristics of face is stable, anchor cable anti-shear ability is weak, utilizes fluid power system to drive rope saw cut anchor
Rope, and the pressure using chute forming machine grab bucket dead weight application to anchor cable.
7）Remove rope saw, hydraulic tube disconnects
After cutting off anchor cable, chute forming machine grab bucket is lifted, rapid removal rope saw frame, disconnect chute forming machine grab bucket hydraulic tube and rope saw hydraulic pressure
Oil pipe, chute forming machine grab bucket continue construction of fetching earth.
The present invention carries out machine anchor cable positioning of fetching earth using diaphram wall, chute forming machine, is set on chute forming machine grab bucket, rope saw frame
Dismounting facility is put, anchor cable is run into during grooving, lifts chute forming machine grab bucket immediately, is installed in advance using facility Fast Installation is dismounted
There is the rope saw frame that rope is sawed（Refer to Fig. 1, Fig. 2, Fig. 3）.
As preferably technical solution, the threaded hole in hydraulic grooving machine grab bucket uses round hole, corresponding rope saw Steel plate frame
On threaded hole use slotted eye, facilitate adjusting rope saw height, more adapt to anchor cable angle, reach cell wall both sides and synchronously cut
The purpose cut.
On chute forming machine after installing rope saw, grooving machine hydraulic system is connected with rope saw drive system（For example connect grooving
The hydraulic oil pipe reserved in machine grab bucket and rope saw driving hydraulic oil pipe）, you can fast driving rope saw carries out cutting operation.
, can fast positioning anchor cable position by chute forming machine grooving operation.After cutting off anchor cable, by rope saw frame dismounting, chute forming machine
Grooving operation is can proceed with, chute forming machine shift position is avoided and causes to reposition, accelerate construction progress.In grooving process
Middle field technician's whole process is stuck to post, and the offset feelings of hydraulic grab during grooving are observed according to the basic data moment of collection
The position of anchor cable is accurately oriented at parameters in condition and construction, scene.Orient anchor cable position strictly control grooving into
Ruler, using saw cut anchor cable of restricting, avoids pullling anchor cable and causing landslip of the sides of the trench.
Anchor cable processing method disclosed by the invention for the anchor cable specific location in wall in foundation pit, in combination in wall construction
Equipment hydraulic grab install shear rope saw additional, be accurately positioned using grab bucket and drive rope saw to cut with hydraulic grooving machine hydraulic system
