Abstract
The invention relates to a method for preventing the water of underground dong structural tunnel, which is characterized in that: before irrigating the well edge concrete of tunnel, embedding the aeration tube whose mouth connects the air chamber and the outside gas resource; before the dong structure enters the hole, mounting the shade rubber plate. And it has the advantages that: the air chamber is aerated when the dong structure enters the hole; using rubber plate to cover the dong structure or the outer surface of lining to realize better water sealing property between the dong structure and the well edge to avoid the soil and water leakage, while can improve the former process that only using soil to strengthen the hole and improve the safety.
Description
Technical field
The present invention relates to the waterproof method class, relate to concretely a kind of be used for the underground structure shield tunnel advance the hole waterproof method.
Background technology
The hole waterproof of advancing of existing shield tunnel is undertaken by the soil stabilization mode, general main is to advance soil body processing modes constructions such as the employing of surrounding area, hole agitation pile, rotary churning pile or freezing process, agitation pile, rotary churning pile are mainly constructed principle for form continuous water-stop curtain in the soil body in the certain limit of hole, excavate the safety of face in conjunction with the well-points dewatering method to guarantee shield; Freezing process is mainly constructed principle for advancing hole employing freezing equipment, makes the soil body in the certain limit freeze hardening, has guaranteed the safety of shield excavation face.Its shortcoming is that the soil stabilization scope is bigger, guarantee that the homogenieity of reinforcing is very difficult, though the on-the-spot detection of can taking a sample, sample point is limited, can't guarantee that the whole soil body all reaches designing requirement.
Summary of the invention
The objective of the invention is according to above-mentioned the deficiencies in the prior art part, what a kind of shield tunnel was provided advances the hole waterproof method, this method is in walling crib import department rubber tile to be set, and by the pressing to it of air bag and steel spring plate, the watertight requirement when satisfying shield.
The object of the invention realizes being finished by following technical scheme:
A kind of shield tunnel advance the hole waterproof method, comprise walling crib, lining segment, cord rubber tile, the cord rubber tile is between walling crib and lining segment outer wall, it is characterized in that this method adopts following step: before cast tunnel walling crib concrete, pre-buried gas tube, the mouth of pipe connects air bag and extraneous source of the gas; Before shield, cord rubber tile, steel spring plate and air bag are installed afterwards; During shield, airbag aeration is expanded, compressing promotes steel spring plate, thereby compresses rubber tile.
Pre-buried gas tube radical is corresponding one by one with the air bag number that is connected.
Wherein the installation of cord rubber tile, steel spring plate can be that steel spring plate and rubber tile are fitted, form fit, and the end of the two is fixedlyed connected with the walling crib inwall, and other end steel spring plate tightly is wrapped in the lining segment outer wall by rubber tile.
Angle Selection is set in the installation of steel spring plate and rubber tile and the lining segment outer wall is about 45, and effect is relatively good.
The installation of steel spring plate also comprises the installation of an other arcuation steel spring plate, the installation site of this steel plate and steel spring plate installation site are arranged in a crossed manner, its mounting method can be that the one end is fixedlyed connected with the walling crib inwall, it is circular-arc that the other end is, this circular-arc end contacts with steel spring plate under the air bag effect after the inflation, and to its generation pressure, what of airbag aeration amount are the size of pressure depend on.
Described fixedly connected be before cast walling crib concrete, embedded nut adopts bolt to connect on the walling crib steel plate afterwards.
Described air bag quantity is two, and the two discharges successively, inflates a back contact pressuring spring steel plate, another contact compressing arcuation latch plate.
Advantage of the present invention is, when shield, airbag aeration expands, rubber tile closely is wrapped in shield structure or lining cutting external surface, make that gap location has good watertightness between shield structure and the walling crib, avoid issuable muddy water seepage, changed the single measure that shield in the past only depends on soil stabilization, improved the safety factor of shield.
Summary of drawings
Accompanying drawing 1 is shield soil stabilization figure;
Accompanying drawing 2 is structural representation of the present invention;
Concrete technical scheme
Feature of the present invention and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-2, label 1-21 represents respectively: the circular-arc end 15 of acorn nut 1, tee junction 2, walling crib 3, packing ring 4, bolt 5, briquetting 6, air bag 7, cord rubber tile 8, steel spring plate 9, arcuation steel spring plate 10, lining segment outer wall 11, gas tube 12, walling crib steel plate 13, acorn nut 14, arcuation steel spring plate 10, shield structure direction of propulsion 16, the soil body through reinforcing 17, space enclosing structure 18, liner 19, pre-buried steel loop 20, steel hoop concrete protective circle 21.
The shield tunnel that present embodiment relates to advance the hole waterproof method, comprise walling crib 3, lining segment outer wall 11, cord rubber tile 8, steel spring plate 9, arcuation steel spring plate 10, air bag 7 and gas tube 12 thereof, cord rubber tile 8 is between walling crib 3 and lining segment outer wall 11, and this method adopts following step:
Before cast tunnel walling crib concrete, pre-buried acorn nut 1 on walling crib steel plate 16, pre-buried two gas tubes 12 simultaneously, gas tube 12 is connected with tee junction 2.
Afterwards before shield, cord rubber tile 8 and steel spring plate 9, arcuation steel spring plate 10, air bag 7 are installed, wherein the installation of cord rubber tile 8, steel spring plate 9 is that steel spring plate 9 and rubber tile 8 are fitted, the two form fit, and end of the two and walling crib steel plate 13 adopt briquetting 6 to be fixed in pre-buried acorn nut 1 place by bolt 5, other end steel spring plate 9 tightly is wrapped in lining segment outer wall 11 by rubber tile 8, and it is to be 45 with lining segment outer wall 11 that the installation of steel spring plate 9 and rubber tile 8 is provided with angle; The installation of arcuation steel spring plate 10, the installation site of this steel plate 10 and steel spring plate 9 installation sites are arranged in a crossed manner, its mounting method is to adopt bolt 5 to be fixed in pre-buried acorn nut 14 places at one end and walling crib steel plate 13, it is circular-arc that the other end is, this circular-arc end contacts with steel spring plate under the air bag effect after the inflation, and to its generation pressure, what of airbag aeration amount are the size of pressure depend on.
When shield, airbag aeration is expanded at last, compressing promotes steel spring plate 9 and arcuation steel spring plate 10, thereby acts on rubber tile 8, makes rubber tile 8 closely be wrapped in lining segment outer wall 11, reaches the watertight requirement.
One end of above-mentioned two pre-buried gas tubes 12 is connected to air bag 7 respectively, and the other end is communicated with extraneous source of the gas by tee junction 2.
Above-mentioned air bag 7 quantity are two, and the two discharges successively, inflate a back contact pressuring spring steel plate 9, another contact compressing arcuation latch plate 10.
In the present embodiment steel spring plate 9 and arcuation steel spring plate 10 and air bag 7 all be to be provided with ringwise along walling crib inwall circumferencial direction.Obviously the setting that those skilled in the art will recognize that air bag 7 also can be evenly segmentation setting along the circumferential direction, and the position of set certainly gas tube is also corresponding with it, so long as can realize steel plate 9, the 10 even application of forces are got final product.
