Abstract
The utility model discloses a starting portal sealing structure of a slurry shield tunnel. The starting portal sealing structure comprises a main body structure, an embedded steel ring buried in the main body structure, a curtain rubber plate connected to the embedded steel ring and at least two steel wire brushes; a grouting hole is formed in the embedded steel ring and located between the two steel wire brushes. Due to the adopted technical scheme, the starting portal sealing structure of the slurry shield tunnel has the advantages that the curtain rubber plate is used of preventing lots of water from rushing out, the two steel wire brushes are in seamless contact with a shield machine shell or a duct piece so as to prevent water seepage, and finally, the grouting hole is formed in the embedded steel ring and a grease is injected to the steel wire brushes to enhance the water plugging effect.
Description
Technical field
the utility model relates to a kind of slurry shield tunnel portal hermetically-sealed construction that starts.
Background technology
in shield launching process, for preventing that mud from pouring in active well in the space between portal circle and shield body, cannot build cabin or affect the stable of the shield machine work plane soil body, must before shield launching, at portal place, well behaved sealing device be set.
portal seal form can be divided into presser type and hinging type.Wherein hinging type is now extensively promoted.Folding paper portal sealing is constructed in two steps, and the first step is in the middle of main structure construction, to carry out the work of burying underground of the portal built-in fitting that starts, pay particular attention to be in the middle of burying process underground built-in fitting must with agent structure in reinforcing bar link together; Second step is before shield structure formally starts, and need first clear up portal dregs, then carries out the installation of portal sealing.
hermetically-sealed construction of the prior art, prevents that by cord rubber tile is set on the pre-buried steel loop being embedded in agent structure swelling from going out, and then sealing effectiveness is not ideal enough, easy spillage when shield machine passes through.
notification number is that the patent of invention of CN103266898A discloses a kind of shield tunnel portal sealing device and method, comprise inwall (being the agent structure described in the application), inwall is provided with pre-buried steel loop, pre-buried steel loop is provided with sealing steel ring, sealing steel ring is provided with twice waterproof construction, and twice waterproof construction is along sealing steel ring radial arrangement; On sealing steel ring, between twice waterproof construction, along even circumferential, have some greasings hole, described twice waterproof construction is respectively wire brush and cord rubber tile, cord rubber tile is arranged in the side near pre-buried steel loop, on described sealing steel ring, on the inner side of cord rubber tile and inwall, all has injected hole.This hermetically-sealed construction, only has wire brush one, and cord rubber tile and wire brush be all positioned at the outside of pre-buried steel loop, can not reach wire brush completely and contact with the seamless of shield machine shell or section of jurisdiction, so sealing effectiveness is also not ideal enough.
Summary of the invention
in order to address the above problem, the purpose of this utility model is to provide a kind of slurry shield tunnel portal hermetically-sealed construction that starts.
in order to reach above object, the technical solution adopted in the utility model is: a kind of slurry shield tunnel portal hermetically-sealed construction that starts, it comprises agent structure, be embedded in pre-buried steel loop in agent structure, be connected to cord rubber tile on pre-buried steel loop and twice wire brush at least, on pre-buried steel loop, offer injected hole, this injected hole is between twice wire brush.
further, injected hole has a plurality of and along the circumferencial direction setting of pre-buried steel loop.
further, twice wire brush is connected on the inwall of pre-buried steel loop.
further, cord rubber tile and a Circular Plate and a turnover panel are fixedly connected by bolt, and Circular Plate is fixedly connected on pre-buried steel loop.
further, in agent structure, also offer the first injected hole, the first injected hole and the injected hole formation grouting pipe that is connected.
owing to adopting technique scheme, the utility model slurry shield tunnel portal hermetically-sealed construction that starts, by cord rubber tile, prevent that a large amount of swellings from going out, the object of the seamless contact preventing infiltration of the realization of twice wire brush and shield machine shell or section of jurisdiction, finally, by default injected hole on pre-buried steel loop, on wire brush, inject grease and strengthen water plugging effect.
Accompanying drawing explanation
accompanying drawing 1 is the start superstructure schematic diagram of portal hermetically-sealed construction of the utility model slurry shield tunnel;
accompanying drawing 2 is the start substructure schematic diagram of portal hermetically-sealed construction of the utility model slurry shield tunnel.
number in the figure is:
1, agent structure; 2, pre-buried steel loop; 3, cord rubber tile; 4, wire brush; 5, injected hole; 6, Circular Plate; 7, the first injected hole; 8, turnover panel.
The specific embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
from the structural representation of accompanying drawing 1 and accompanying drawing 2, can find out, the utility model provides the slurry shield tunnel portal hermetically-sealed construction that starts, it comprises agent structure 1, be embedded in pre-buried steel loop 2 in agent structure 1, be connected to cord rubber tile 3 on pre-buried steel loop 2 and twice wire brush 4 at least, on pre-buried steel loop 2, offer injected hole 5, this injected hole 5 is between twice wire brush 4.
cord rubber tile 3 and a Circular Plate 6 and a turnover panel 8 are fixedly connected by bolt, and Circular Plate 6 and turnover panel 8 lay respectively at the both sides of cord rubber tile 3, and Circular Plate 6 is fixedly connected on pre-buried steel loop 2.When shield launching seals by portal, the bending direction of cord rubber tile 3 and turnover panel 8 is consistent with the direction of propulsion of shield structure, contrary with the flow direction of water, sand or slurries, turnover panel 3 and cord rubber tile 8 just can bear the pressure that leakage produces like this, once there be water or the slurry stream door sealing of appearing just can play the effect of shutoff.
twice wire brush 4 is connected on the inwall of pre-buried steel loop 2, realizes and contacting with the seamless of shield machine shell or section of jurisdiction.
it is a plurality of and along the circumferencial direction setting of pre-buried steel loop 2 that injected hole 5 has.In agent structure 1, also offer a plurality of the first injected hole 7, the first injected holes 7 and the injected hole 5 formation grouting pipe that is connected.By inject grease on wire brush 4, strengthen water plugging effect.
above-described embodiment is only explanation technical conceive of the present utility model and feature, and its object is to allow person skilled in the art can understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, within all should being encompassed in protection domain of the present utility model.
