Description
Technical field
The present invention relates to a kind of construction method for dismantling solid concrete roabed.
Background technology
It is divided into by the structure type of track traffic solid concrete roabed：Cast-in-place solid concrete roabed, cast-in-place rubber remove from office into pad solid concrete roabed,
Prefabricated chunk formula floating plate railway roadbed and the common railway roadbed of prefabricated chunk formula.The current built subway of China or the subway built, big portion
Divide and build solid concrete roabed using cast-in-place, it is a small amount of that cheese block railway roadbed is removed from office into using rubber, with the introduction of high ferro technology, with damping effect
It is really good, build pollute small, short construction period, maintenance easily device of shifting block type solid concrete roabed by be urban rail transit construction development side
To.Cast-in-place solid concrete roabed will be substituted progressively by device of shifting block type solid concrete roabed.In order to reduce the construction cost of device of shifting block type solid concrete roabed,
Generally all it is that to have two methods under the shield tunnel using former cast-in-place solid concrete roabed, prior art cast-in-place to disassemble during construction
Solid concrete roabed：One is the concrete substrate that solid concrete roabed is manually smashed using air compressor machine, this method not only inefficiency, noise
Greatly, the disintegrating slag produced is more, and easy damaged section of jurisdiction；Two be first by the big portion of solid concrete roabed concrete substrate using rope away from cutting machine
Segmentation is fallen, and the part that residue can not be sliced off manually is smashed again, and this method very waste water resource, efficiency is low, the dust of generation
Big and poor removal effect.
The content of the invention
It is an object of the invention to solve to dismantle the dirt that cast-in-place solid concrete roabed efficiency is low, effect is poor, cause under prior art
The problem of contaminating big and easy damaged section of jurisdiction, and a kind of construction method for dismantling solid concrete roabed is provided.
The purpose of the present invention is achieved by the following technical programs：
A kind of construction method for dismantling solid concrete roabed, it is characterised in that comprise the following steps：
（1）, first remove rail on solid concrete roabed, then the concrete substrate at the tank of solid concrete roabed is got rid of and transported
Walk；
（2）, using cutter device solid concrete roabed is cut off and grooving by certain length, dismounting section is split with solid concrete roabed
Open, be sure not to hurt section of jurisdiction during cutting；
（3）, again thrustor is placed in grooving, thrustor side is fixed on the section of solid concrete roabed, opposite side
On the section for withstanding dismounting section, it will dismantle section using the jacking force of thrustor and be promoted from section of jurisdiction, and produce certain displacement amount,
Peeled off with and by the section from section of jurisdiction；
（4）, the dismounting section peeled off is hung to flat car and is transported out tunnel.
Described section of jurisdiction includes constituting all piecemeals of section of jurisdiction ring, i.e. shield duct piece.
The cutter device includes the rack-track that an arc is set on support frame, support frame, and rack-track is provided with
Movable stand, movable stand is provided with power transmission shaft, and power transmission shaft one end is connected with main hydraulic motor, and the other end is connected with saw blade, movable stand also
A pair of gears by secondary fluid motor-driven are set, and wheel and rack track is engaged, make movable stand on rack-track back and forth
It is mobile.
The thrustor includes hydraulic control device and riser, the hydraulic pressure that the uniform one group of axis horizontal in riser side is set
Cylinder, each hydraulic cylinder is connected with hydraulic control device by oil pipe respectively, needs riser being fixed on cutting for solid concrete roabed before work
On face, when hydraulic cylinder moves reciprocatingly, its piston rod supports on the section to dismounting section and carries out pushing tow.
When cutter device solid concrete roabed do not cut flat with or thrustor hydraulic cylinder curtailment when, it is necessary in dismounting section
Section add backing plate carry out it is levelling, the thickness of backing plate should be determined according to practice of construction situation, to ensure each liquid of thrustor
Cylinder pressure can prop up the section of dismounting section simultaneously, and divide equally the pushing tow pressure of its hydraulic cylinder, prevent from pushing up the section of broken dismounting section.
In order to which solid concrete roabed is stripped down from section of jurisdiction, therefore thrustor is needed to provide enough jacking force, the pushing tow
Power can not only promote the railway roadbed of dismounting section to produce certain displacement amount on section of jurisdiction, but also can not push up the section of broken dismounting section, because
And the size of the jacking force needs limitation.
According to the actual conditions of subway solid concrete roabed：If the concrete substrate of solid concrete roabed is contacted into seam with shield duct piece to regard
For cold seam, then required jacking force should be the frictional resistance overcome completely on the two contact surface, be cut along with all in dismounting section
The shearing resistance of power key, that is, draw minimum jacking force：Applied if with shield duct piece the concrete substrate of solid concrete roabed is contacted into seam and is considered as
Work is stitched, then the contact surface between the two is integrally formed for bonding completely, the two is peeled off, then required jacking force should be complete gram
Shearing resistance on the two contact surface of clothes, along with the shearing resistance of all shear connectors in dismounting section, that is, draws maximum jacking force.Typically
It need to only implement during site operation according to maximum jacking force.
The beneficial effects of the present invention are dismounting labor intensity is reduced, the disintegrating slag and dust of generation are few, and removal is thorough,
While improving dismounting solid concrete roabed efficiency, the overall progress of track transformation construction is also improved, the pollution to working environment is small.
Just it is described with reference to the drawings that the invention will be further described with embodiment below.
