Description
Technical field
The invention belongs to tunnel water proofing technical field, specifically a kind of shield tunnel segment bolt hole water proof structure and apply
Work method.
Background technique
Shield tunnel is the structure formed by muti-piece prefabricated pipe section on-site consolidation, is bolted between section of jurisdiction,
Underground water leaks into tunnel from segment joint in order to prevent, and seam crossing is provided with waterproof sealing gasket on the outside of section of jurisdiction,
Hydro-expansive rubber sealing ring is arranged in bolt, and carries out filleting in inside, in the higher engineering of waterproof requirement, leans on proximity
Seam inside is also provided with second waterproof sealing gasket.In practical projects, due to prefabricated pipe section quality, assembled quality of constructing, close
The influence of the factors such as packing sticking Quality, outer side seal pad leakage is very difficult to avoid completely, or even is leaked very in individual engineerings
Seriously.
After outer side seal pad leaks, water flow may enter tunnel along bolt hole, thus bolt hole be provided with it is anti-
Water construction.But from " certain crosses the percolating water analysis of causes of river Shield-bored tunnels section of jurisdiction and Treatment process " (Chinese architecture waterproof,
6th phase in 2015), " analysis of causes of shield tunnel percolating water and counter-measure " (urban architecture, the 8th phase in 2013) and " shield
Structure treatment technology for tunnel seepage water process construction technology " documents such as (urban architecture, o. 11th in 2015) can be seen that segment bolt aperture infiltration
The phenomenon that leakage, often occurs.
Duct pieces of shield tunnel link bolt hole waterproof, which is all made of, at present is arranged triangular-section in bolt chamfering position
The mode of water swelling rubber ring.Due to diameter of bolt hole 6mm generally bigger than the diameter of bolt or so, sealing ring water-swellable is backward
It is squeezed out in bolt hole, due to there is no sidewise restraint, can not form the bulbs of pressure, therefore waterproof effect is very poor.In addition, hydro-expansive rubber
Material is poor in long period of soaking condition stability inferior, and water-absorbent material is easy to be lost from the elastomer network of rubber, shows as growing
Phase or the repeatedly biggish mass loss in immersion front and back and physical property decline.That is the water-swellable rubber generallyd use at present
Expansive force cannot be generated existing for cushion rubber when water-swellable, does not have due waterproof action, and stability and durability are insufficient.
Summary of the invention
The problem of for background technique, the present invention propose it is a kind of from waterproof sealing gasket material and working principle, it is close
Packing construction, gasket installation site etc. carry out comprehensive improvement, to solve the insufficient shield tunnel of the prior art
Segment bolt hole water proof structure and construction method.
In order to achieve the above objectives, the shield tunnel segment bolt hole water proof structure that the present invention designs, including it is located at bolt
The bolt of hole inner connection tube piece, the bolt washer between the bolt head and section of jurisdiction of bolt, it is characterised in that: further include being located at
The first waterproof washer between bolt washer and section of jurisdiction, the second waterproof washer between bolt head and bolt washer；It is described
The one side that first waterproof washer is contacted with the section of jurisdiction is plane, and it is semicircle that the one side contacted with bolt washer is equipped with an at least ring
Protrusion；Two end faces of second waterproof washer are plane.
Preferably, the internal diameter of first waterproof washer is greater than the internal diameter of bolt washer, and outer diameter is no more than bolt washer
Outer diameter；The internal diameter that the diameter of the semi-cylindrical hill is greater than the first waterproof washer is less than the outer diameter of bolt washer.
It is further preferred that first waterproof washer is equipped with polycyclic semi-cylindrical hill, two adjacent semi-circular projections
Diameter difference be 10~20mm.
Preferably, first waterproof washer is made of ethylene propylene diene monomer (EPDM) material.
Preferably, the section of jurisdiction is equipped with the limiting slot for accommodating first waterproof washer.
It is further preferred that the depth of the limiting slot is 2~4mm.
Preferably, the internal diameter of second waterproof washer is not less than the diameter of bolt, and outer diameter is less than bolt head inscribed circle diameter.
Preferably, second waterproof washer uses neoprene or EP rubbers material.
Using the shield tunnel segment bolt hole waterproof construction side of above-mentioned shield tunnel segment bolt hole water proof structure
Method, comprising the following steps:
One) limiting slot is carried out when prefabricated pipe section together, is glued the first waterproof washer using bonding agent before section of jurisdiction is gone into the well
It is attached in limiting slot, section of jurisdiction it is assembled must not to send underground, and must not connect with water in 12 hours for pasting the first waterproof washer of installing
Touching；
Two) when segment assembly, successively the second waterproof washer and bolt washer is set on bolt, pass through tools for bolts ' pretension pair
First waterproof washer and the second waterproof washer carry out densification and then play waterproof action, and can realize by adjusting bolt pretightening
Resist the requirement of different water pressures.
Preferably, step 1) in binder use modified environment protection type polychloroprene tackifier, the brushing binder on section of jurisdiction
Afterwards, cool to set a period of time, when finger contacts adhesion, then the limiting slot the first waterproof washer being entirely attached on section of jurisdiction
It is interior.
It is further preferred that the cool time set is 10~15 minutes.
The beneficial effects of the present invention are: 1. can be improved bolt hole waterproofing pressure.Existing hydro-expansive rubber washer waterproof side
Formula can be expanded along the gap between bolt hole and bolt into bolt hole after meeting water due to washer, and expanded rubber is in no constraint
In the case where cannot generate the bulbs of pressure, when there is hydraulic pressure effect, do not have waterproof effect.The waterproof project that the present invention uses is
By the first waterproof washer between section of jurisdiction and bolt washer and the second waterproof washer between bolt head and bolt washer in spiral shell
The effect of bolt pretightning force is lower to generate compression stress, to realize the waterproof purpose of bolt hole.2. scheme proposed by the present invention, can basis
It needs to adjust the size of bolt pretightening, by changing the contact stress of waterproof washer and section of jurisdiction and bolt washer, thus real
Existing different waterproofing pressure requirement.3. washer material of the present invention and hydro-expansive rubber ratio have better durability.
