Abstract
The utility model belongs to tunnel construction equipment field especially relates to prevent submerged cushion device of opening shield tail pipe piece. Including bottom section of jurisdiction, both sides section of jurisdiction and the top section of jurisdiction of forming the section of jurisdiction domain, bottom section of jurisdiction below hoop is equipped with cushion mechanism, and cushion mechanism comprises the cushion of the equidistant setting of several, and the cushion is rectangular size, the length direction of cushion and the axis direction syntropy of the section of jurisdiction domain. The utility model discloses a cushion mechanism that the several cushion is formed lays this cushion mechanism in the below of bottom section of jurisdiction earlier before installation bottom section of jurisdiction, then installation bottom section of jurisdiction, both sides section of jurisdiction and top section of jurisdiction in proper order, has avoided opening shield tail pipe piece to sink and the phenomenon of the wrong platform in section of jurisdiction effectively, has improved the construction quality of section of jurisdiction structure.
Description
Technical field
The utility model belongs to constructing tunnel apparatus field, particularly relates to the pad device preventing opening shield tail pipe sheet from sinking.
Background technology
After China enters 21 century, large-scale basis facilities item starts to implement, and a large amount of long tunnel excavates.TBM mining method has that driving speed is fast, operating environment good, comprehensive benefit advantages of higher, is the main selection of domestic and international method for tunnel construction.In the construction of TBM mining method, except playing the behind slurries of filling effect, section of jurisdiction is the unique lining cutting in tunnel, stress system, so quality and application life that quality directly affects tunnel are installed in section of jurisdiction., easily there is the situation that section of jurisdiction, opening shield tail place sinks, and then cause the series of problems such as section of jurisdiction faulting of slab ends in Segment assembling method of the prior art.
Utility model content
The purpose of this utility model is to provide one and prevents opening shield tail pipe sheet sinking pad device, and the utility model structure is simple, with low cost, can effectively prevent section of jurisdiction, opening shield tail place from sinking.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
Prevent opening shield tail pipe sheet sinking pad device, comprise the section of jurisdiction, bottom of the composition section of jurisdiction domain, section of jurisdiction, both sides and section of jurisdiction, top, below described section of jurisdiction, bottom, hoop is provided with cushion block mechanism, cushion block mechanism is made up of the cushion block of several spaced set, cushion block is cuboid-type, and the length direction of cushion block and the axis direction of the section of jurisdiction domain are in the same way.
Preferably, described cushion block dimensional parameters is 300mm × 100mm × 90mm.
Preferably, described cushion block is C35 concrete precast block.
Preferably, be installed with anchor metal bottom described cushion block, anchor metal inserts ground.
The utility model compared with prior art, tool has the following advantages: the cushion block mechanism that the utility model consists of several cushion block, before section of jurisdiction, bottom is installed, first this cushion block mechanism is laid on the below of section of jurisdiction, bottom, then section of jurisdiction, bottom, section of jurisdiction, both sides and section of jurisdiction, top are installed successively, efficiently avoid the phenomenon of the sinking of opening shield tail pipe sheet and section of jurisdiction faulting of slab ends, improve the construction quality of tunnel segment structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the pad device preventing opening shield tail pipe sheet from sinking in detailed description of the invention;
Fig. 2 is the structural representation of cushion block in Fig. 1;
Be labeled as in figure: section of jurisdiction, bottom 1, section of jurisdiction domain outline line 2, cushion block 3, tunnelling outline line 4.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1-2, prevent the pad device that opening shield tail pipe sheet sinks, comprise the section of jurisdiction, bottom 1 of the composition section of jurisdiction domain, section of jurisdiction, both sides and section of jurisdiction, top, cushion block mechanism is circumferentially with below described section of jurisdiction, bottom 1, cushion block mechanism is made up of the cushion block 3 of several spaced set, cushion block 3 is in cuboid-type, and the length direction of cushion block 3 and the axis direction of the section of jurisdiction domain are in the same way.Described cushion block 3 is C35 concrete precast block, and its dimensional parameters is 300mm × 100mm × 90mm.
Be installed with anchor metal bottom cushion block 3, anchor metal inserts ground.
Cushion block is cheap, and the mould of this cushion block prefabricated adopts 10mm wide, and the band steel that 4mm is thick is welded; Cushion block material is C35 concrete, and use mould to be that 300mm is long by cushion block dimensioned, 90mm is high, the rectangular structure that 100mm is wide.
Position, section of jurisdiction, bottom 1 on section of jurisdiction domain outline line 2, several cushion block 3 is laid around section of jurisdiction domain outline line 2 circumference, wherein the length direction of each cushion block 3 and the section of jurisdiction domain axially in the same way, after cushion block 3 is put, section of jurisdiction 1, bottom, section of jurisdiction, both sides and section of jurisdiction, top are installed successively.All cushion blocks 3 form the phenomenon that cushion block mechanism can efficiently avoid the sinking of opening shield tail pipe sheet and section of jurisdiction faulting of slab ends, improve the construction quality of tunnel segment structure, have saved the cost of later stage pipe-plate lining structural repair.
In order to improve the supporting effect of cushion block 3, in cushion block prefabrication process, anchor metal can be set firmly bottom cushion block 3, when cushion block 3 is laid, anchor metal can be inserted the ground at tunnelling outline line 4 place.
