Description

It is a kind of to overhaul the glass fiber-reinforced polymer mesoporous stake of cleaning for cutter head of shield machine front and apply Work method
Technical field
It is the present invention relates to shield tunnel design and construction technical field, in particular to a kind of to be overhauled for cutter head of shield machine front The glass fiber-reinforced polymer mesoporous stake of cleaning and its construction method.
Background technique
Shield-tunneling construction engineering method due to having many advantages, such as not influenced by traffic above-ground, highly-safe, the construction period is short and becomes Construction of Urban Rail Traffic first choice, main construction.But due to the uncertainty on stratum, the shield in tunneling process Machine knife disk often will appear various problems, can not normally tunnel so as to cause shield machine, cutter head of shield machine in shield tunneling process It is mainly shown as following two classes problem:
Problem one: shield is tunneled in sand-pebble layer, especially contains large-sized erratic boulder stratum, and it is tight often to will appear cutterhead abrasion Weight or swaging clamp situation, at this moment need to place under repair to cutter head of shield machine, to guarantee the normal driving of shield.
Problem two: shield is tunneled in clay layer, and clay particle is easy to be attached on cutterhead under hyperbaric environment, is caused Cutterhead is dead by paste, cutter can not cutting soil, boring parameter is abnormal, needs to clear up cutter head of shield machine.
For two problems that cutter head of shield machine in the above shield tunneling process often occurs, common solution is:
For problem one, currently used solution is that ground opens a position and abolishes, i.e., from ground construction vertical shaft, until cutterhead position It sets, then construction personnel is directly lower arrives cutterhead position, carries out maintenance or tool changing to shield cutter.But this method investment compared with Greatly, the construction period is longer, and in front of the breakage in installation of vertical shaft shield original state soil layer stability, need to carry out when shield pushes away again Backfilling of earthwork abolishes main structure, not can guarantee construction quality, and working procedure is cumbersome on the whole, and economy is poor.
For problem two, currently used solution is to open a position.This method has main steps that: progress precipitation first Operation, is down to shield bottom or less at least 0.5m for water level, then with soil layer in front of configured mud grouting and reinforcing shield, guarantees The stabilization of face after shield opens a position, operating personnel enter in native storehouse, clear up " mud cake " in front of cutter head of shield machine.This kind of method It needs that specially the face soil body in front of shield is reinforced and handled, the construction period is longer and construction cost is higher, and needs Wanting operating personnel to enter has within the scope of the native storehouse of pressure, and risk is higher.
In conclusion at present for the processing side of cutter head of shield machine failure in shield tunneling process and knot " mud cake " phenomenon Method: one side construction cost is higher, and the construction period is longer;On the other hand needing operating personnel to enter has in the native storehouse of pressure, constructs Risk is higher, and especially under the geological conditions of rich water, working measure investment and construction risk can be bigger.
Summary of the invention
The present invention provides a kind of stake of glass fiber-reinforced polymer mesoporous and its construction party that cleaning is overhauled for cutter head of shield machine front Method can be overhauled or be cleared up to cutter head of shield machine in the case where not opening a position, do not need operating personnel enter Tu Cang and It is smaller to soil layer disturbance, construction cost can be reduced, shorten the construction period, while can also substantially reduce operating personnel's construction risk.
The technical solution adopted by the present invention to solve the technical problems is:
A kind of glass fiber-reinforced polymer mesoporous stake for the maintenance cleaning of cutter head of shield machine front, including by external glass fiber-reinforced polymer cage The mesoporous stake skeleton of composition and the mesoporous stake core being made of the concrete that inside pours;The concrete is provided with longitudinal hole, The side wall of the longitudinal hole offers construction operation mouth corresponding with cutter head of shield machine position;Deviate mesoporous in the central axes of longitudinal hole Cutter head of shield machine side is biased in the central axes of stake.
Further, the glass fiber-reinforced polymer cage is by glass fiber-reinforced polymer main reinforcement, screw type glass fibre stirrup, round glass Glass fiber bar reinforces stirrup and forms cylindrical cage body.
Further, the diameter of the mesoporous stake is not less than 1.5m, and the diameter of the longitudinal hole is not less than 0.8m, described vertical Deviate 10 ~ 30cm of central axes of the mesoporous stake to the central axes in hole.
Further, the longitudinal hole aperture depth is located at cutter head of shield machine cross central line or less;The mesoporous stake Long stake is more than cutter head of shield machine cross central line or less at least 2m.
Further, the construction operation mouth is that the cutter head of shield machine incision 30 ~ 50cm of mesoporous stake side wall is formed.
Further, concrete strength is preferably between C25 ~ C30.
A kind of construction method of front maintenance cleaning cutter head of shield machine, constructs the glass fiber-reinforced polymer mesoporous stake, maintenance Personnel can utilize the construction operation mouth maintenance cleaning shield machine knife of side wall directly by arriving cutter head of shield machine position under longitudinal hole Disk.
Including construction procedure in detail below:
1) it performs glass fibre rib concrete pile: in previously selected shield with regard to stop position, drilling is performed, then by multiple glass Glass fiber bar is bound into glass fiber-reinforced polymer cage, and is transferred in drilling, casting concrete;
2) it bores longitudinal hole: after concrete reaches initial set, boring the longitudinal direction in glass fibre rib concrete pile with churning driven Hole, hole location are biased to shield machine side;
3) open up construction operation mouth: cutting shield is tunneled forward, and cuts longitudinal hole side wall, opens up side wall construction operation mouth, from And complete the production of the glass fiber-reinforced polymer mesoporous stake;
4) overhaul: service personnel can be examined directly by arriving cutter head of shield machine position under longitudinal hole using the construction operation mouth of side wall Repair cleaning cutter head of shield machine;In maintenance scale removal process, cutter head of shield machine is rotated, cutter head of shield machine can be carried out comprehensive Maintenance, cleaning.
Further, the step 2) churning driven drills before final set after glass fiber-reinforced polymer concrete initial set, is formed vertical Xiang Kong.
The beneficial effects of the present invention are:
It is smaller without opening a position and disturbing to soil layer to provide one kind, the mesoporous stake that directly can carry out maintenance cleaning to cutter head of shield machine fills It sets, does not on the one hand need construction personnel and enter Tu Cang, evaded the risk that opens a position;On the other hand it can shorten the construction period, save Construction cost, with good economic efficiency and social benefit.
