Specific embodiment
The present invention will be further described combined with specific embodiments below.It should be understood that within the scope of the present invention, it is of the invention
It can be combined with each other between above-mentioned each technical characteristic and specifically described in below (e.g. embodiment) each technical characteristic, thus
Constitute new or preferred technical solution.Due to space limitations, I will not repeat them here.It is all to be realized based on above content of the present invention
Technology all 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, leading wall is
Guarantee that diaphram wall position accurately leads wall and often bear steel reinforcement cage, pour concrete use with the key of grooving quality in construction period
The static and dynamic loadings such as conduit, drilling machine effect, thus conscientiously must design and construct, just can be carried out the formal of diaphram wall
Construction.
Diaphram wall, which should all be arranged, leads 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 be selected according to different soil properties.When soil layer property is preferable, inverted "L" shape can be selected or even pre-manufactured steel leads wall, use
" L " type leads wall, and what Ying Jiaqiang led wall behind is backfilling and compacted work.Ground good location in surface layer is led using simple form reinforced concrete
Wall；Wall is led using cast-in-place L shape reinforced concrete in the area of topsoil weakness.
Construction of guide wall is to ensure that the axial location of subterranean wall and grooving quality have critical process.In order to keep ground surface soil body
Stablize, attaches interim wood support and stull between wall every 1~3 meter leading；The construction precision for leading wall is directly related to underground company
The precision of continuous wall, thus construct lead wall when, it has to be noted that lead the headroom size, vertical and horizontal precision and plane position of side within the walls
It sets.The horizontal reinforcement for leading wall must connect, and make to lead wall as an entirety, prevent due to intensity is insufficient or construction is not good at
Generation accident.For the construction precision for guaranteeing subterranean wall, be convenient for grooving machine operation, lead side clearway within the walls should compared with subterranean wall thickness slightly
It is larger (5cm bigger than design value), wall top mouth is led than ground and is higher by 5cm, and the depth for leading wall is 1.5m.Lead the construction error mark of wall
Standard is: centerline error is ± 10mm；Absolute altitude error is ± 10mm in the length range of top surface.
Wall effect is led in diaphram wall: 1, providing guiding to chute forming machine grooving；2, it stores mud and prevents notch from collapsing；
3, the benchmark of level and vertical measurement when as construction；4, it is placed for steel reinforcement cage, tremie disposes, chute forming machine provides mark

Construction process: construction of guide wall --- chute forming machine positioning --- grooving operation --- encountering anchor cable --- grab bucket installing rope
Saw, hydraulic tube connection --- excision anchor cable --- remove rope saw, hydraulic tube disconnects.
Specific steps:
1) it positions
Construction of guide wall is according to geological condition, using different form.
2) chute forming machine positions
Grooving process point three grabs carry out grooving, after verifying first of anchor cable position, according to design requirement again to underground
Diaphragm wall carries out framing, and chute forming machine is positioned according to framing line position, it is ensured that grooving verticality and position are accurate.
3) grooving operation
It is 2.8m that native width is grabbed in chute forming machine grab bucket (as shown in Figure 3) every time, and in order to guarantee the verticality of grooving, chute forming machine is set
There is random monitoring deviation correcting device.
4) anchor cable is encountered
Since anchor cable intensity is higher, chute forming machine is difficult to directly grab disconnected, pulls the generation that will lead to the hole that collapses by force, chute forming machine is grabbed
Bucket, which cannot be closed verify during taking soil, has anchor cable at this.
5) grab bucket installing rope saw, hydraulic tube connection
After tentatively verifying anchor cable position, anchor cable specific location is further verified using magnet, by saw frame Fast Installation of restricting
Onto chute forming machine grab bucket, the hydraulic oil pipe and rope saw driving hydraulic oil pipe reserved in connection chute forming machine grab bucket.
6) anchor cable is cut off
Using rope sawing except the feature that face is stable, anchor cable anti-shear ability is weak, rope sawing is driven using fluid power system
Anchor cable is cut, and applies the pressure to anchor cable using chute forming machine grab bucket self weight.
7) rope saw is removed, hydraulic tube disconnects
After cutting off anchor cable, chute forming machine grab bucket is lifted, rapid removal rope saw frame, disconnects chute forming machine grab bucket hydraulic tube and rope is sawed
Hydraulic oil pipe, chute forming machine grab bucket continue to take native construction.
The present invention carries out that native machine anchor cable is taken to position using diaphram wall, chute forming machine, sets on chute forming machine grab bucket, rope saw frame
Dismounting facility is set, encounters anchor cable during grooving, lifts chute forming machine grab bucket immediately, is installed in advance using dismounting facility Fast Installation
The rope saw frame (being detailed in Fig. 1, Fig. 2, Fig. 3) for thering is rope to saw.
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 the angle of anchor cable, reach cell wall two sides and synchronize and cut
The purpose cut.
On chute forming machine after installing rope saw, grooving machine hydraulic system is connect with rope saw drive system (such as connection grooving
The hydraulic oil pipe reserved in machine grab bucket and rope saw driving hydraulic oil pipe), it can fast driving rope saw progress cutting operation.
By chute forming machine grooving operation, anchor cable position can be quickly positioned.After cutting off anchor cable, by rope saw frame disassembly, chute forming machine
It can proceed with grooving operation, avoid chute forming machine shift position and cause to relocate, 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 the strict control grooving of anchor cable position into
Ruler avoids pullling anchor cable and leading to landslip of the sides of the trench using rope saw cut anchor cable.
Anchor cable processing method disclosed by the invention is for the specific location in anchor cable in foundation pit wall, in combination in wall construction
Equipment hydraulic grab install additional shear rope saw, using grab bucket be accurately positioned and hydraulic grooving machine hydraulic system driving rope saw cut
Disconnected anchor cable cuts anchor cable while grooving to achieve the purpose that processing to reach processing intent, safety is good, short time limit,
Strong operability.
The above content is only presently preferred embodiments of the present invention, for those of ordinary skill in the art, according to the present invention
Thinking, place can be changed in specific embodiment mode and its application range, the content of the present specification should not be construed as
Limitation of the present invention.
