Description
Technical field:
The utility model relates to a kind of hexagon sections of jurisdiction in tunnel boring machine tunnel.
Background technique:
The clay ingredient on swelled ground stratum (swelled rock and soil) is mainly made of strongly hydrophilic mineral montmorillonite and illite, this
Class mineral have the stronger ability in conjunction with water, water swelling, dehydration shrinkage, and have the characteristic of reciprocal breathing.Expand soil
Layer can generate expansive force when water swelling is by external constraint in the soil body.Therefore, tunneling is in swelled ground stratum,
Water swelling once occurs for the soil body, and the lining cutting in tunnel can bear the biggish bulbs of pressure, so as to cause lining deformation and destruction.
It is a kind of by rotation that full face tunnel boring machine, which is also known as tunnel boring machine (Tunnel Boring Machine, abbreviation TBM),
And cutterhead is promoted, knife fractured rock is rolled by dish type, and the construction of tunnel for keeping tunnel tunneling boring once-forming is mechanical.Tunnel
The great advantage of hole tunneler construction is exactly that cavitation speed is fast, wherein to construct the speed of tunnel-liner most using hexagon section of jurisdiction
Fastly.Hexagon section of jurisdiction actually precast member for reinforcing bar concrete, (vertical view) is in fan annular in terms of top surface；(facing) is in six in terms of front
In " > " shape of protrusion, upper and lower sides are linear type for side shape, i.e. both ends；Therefore claim hexagon section of jurisdiction.The width (six of hexagon section of jurisdiction
Distance between two long sides of side shape) it is generally two strokes of tunnel boring machine.The installation exercise of section of jurisdiction is in tunnel boring machine
Afterwards in shield, and progress synchronous with tunnel excavation, section of jurisdiction are staggeredly engaged and are assembled into annulus, form the liner structure in tunnel.Due to
Section of jurisdiction is that occlusion is assembled, the gap very little between section of jurisdiction, if still using such liner structure, expansive rock on swelled ground stratum
Soil body water swelling can generate biggish expansion extruding force to lining cutting, cause lining cutting to generate biggish internal force, thus to lining cutting
Mechanical property requirements greatly improve.Though the compressive property of lining cutting can be improved by increasing reinforcing bar amount, section of jurisdiction is increased
Preparation and assembled cost.
Utility model content:
The purpose of the utility model is to provide a kind of hexagon section of jurisdiction in the tunnel boring machine tunnel on swelled ground stratum, this kinds
Hexagon section of jurisdiction can reduce the equivalent stiffness of lining cutting, effectively reduce the expansive force acted in lining cutting, to guarantee to be built in expansion
The tunnel structure in the tunnel boring machine tunnel of soil layer it is safe and reliable；And there is good waterproof performance.
The utility model realizes its goal of the invention the technical scheme adopted is that a kind of tunnel boring machine on swelled ground stratum
The hexagon section of jurisdiction in tunnel, it is characterised in that:
The hexagon section of jurisdiction end Liang Ge is opened there are three through hole up and down, and the upper end of through hole is located at end
The upper surface in portion, the lower end of through hole are located at the lower end surface of end；Rubber bar, and the upper end of rubber bar are filled in through hole
Face, lower end surface are flushed with upper surface, the lower end surface of hexagonal tube piece end respectively；
Be bonded on hexagonal tube piece end with the matched rubber slab in hexagonal tube piece end, rubber slab be equipped with capillary groove and
The water-proof strip being adapted to capillary groove；And hexagon section of jurisdiction one end bonding rubber slab on capillary groove and the other end bonding
Water-proof strip on rubber slab is located at the ipsilateral of hexagon section of jurisdiction.
Compared with prior art, the utility model has the beneficial effects that
One, the staggeredly occlusion assembly between the hexagonal tube piece end of the utility model is no longer direct rigid between concrete
Property splicing, and become the flexible connection between the rubber slab of end.When the generation water swelling of swelled ground stratum, biggish expansion is generated
When power, expansive force can be absorbed by rubber slab flexible, effectively reduced the expansive force acted in lining cutting, avoided to liner structure
It destroys.When expansive force effect is very big, the through hole of section of jurisdiction end can stress concentrate, occur Local Cracking, formation can be into
The end of row maintenance and reinforcement is destroyed, and the tunnel after reinforcement and repair remains to normal use.So as to avoid section of jurisdiction overall structure by
It destroys, reinforcing cannot be repaired, tunnel can only be scrapped the problem of abandoning.In short, the utility model reduces the equivalent of lining cutting
Rigidity effectively reduces the expansive force acted in lining cutting and the destruction to liner structure, ensure that tunnel structure safety, can
It leans on, improves the service life in tunnel.
Two, hexagonal tube piece end rubber slab capillary groove carries out chimeric with adjacent hexagons section of jurisdiction collision mat, can be effective
The entrance of water is obstructed, so that the tunnel structure of the utility model has good waterproof performance.
Three, main structure, the size of the hexagon section of jurisdiction of the utility model do not change, and do not have to when production change existing pipe
Piece template, preparation cost increase is small, is convenient for promotion and implementation.
The course of work and application method of the utility model are:
A, 3 arc-shaped steel tubes, then casting concrete are vertically fixed respectively at the both ends of the mold of hexagon section of jurisdiction, mix
Arc-shaped steel tube is taken out after solidifying earth forming, both ends is obtained and opens that there are three the hexagon sections of jurisdiction of through hole up and down；
B, diameter of section columned rubber bar identical with the internal diameter of arc-shaped steel tube is made using neoprene raw material,
Rubber bar is inserted into through hole, and cut rubber bar to make the end face of its end Yu hexagon section of jurisdiction；
C, with neoprene raw material be made with the matched rubber slab in hexagonal tube piece end, and rubber slab with capillary groove and
The water-proof strip being adapted to capillary groove；
D, rubber slab is bonded on hexagonal tube piece end using the adhesive of neoprene, and hexagon section of jurisdiction one end
Capillary groove on the rubber slab of portion's bonding and the water-proof strip on the rubber slab of the other end bonding are located at hexagon section of jurisdiction rubber slab
It is ipsilateral.
This method is simple to operate, and cost low energy rapid build goes out to be used for the tunnel boring machine tunnel on swelled ground stratum
Hexagon section of jurisdiction.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
