Description
Technical Field
The invention relates to the technical field of tunnel waterproofing, in particular to a rubber hinge plate sealing structure suitable for a micro shield.
Background
The shield construction technology has the advantages of small influence on the ground structure, no adverse effect on the environment, low labor intensity of workers, high mechanization degree, high engineering progress, accurate tunnel shape, high quality and the like, and is an important construction technology in urban rail transit construction in China. The shield method is a construction method for underground excavation of soft soil stratum tunnels, and enables a shield tunneling machine to construct along the axis and the elevation position of a preset tunnel by using a working well. The existing shield method construction has the problems of high shield tunneling technology difficulty, multiple potential safety hazards, easiness in collapse, water leakage and the like. The existing commonly used water seepage prevention method is that a rubber sheet is arranged at a hole, one end of the rubber sheet is fixed on the outer wall of the hole through a steel plate bolt, and the other end of the rubber sheet is turned over in the hole and positioned between a shield machine and the inner side wall of the tunnel, so that the structure is simple, and the sealing effect is limited.
Disclosure of Invention
The invention provides a rubber hinge plate sealing structure suitable for a micro shield, which has good sealing effect and is convenient to operate.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides a rubber flap seal structure suitable for little shield, its characterized in that: including the steel sheet ring, the rubber that set gradually turn over board and fixed plate, be equipped with the sheet rubber on the fixed plate, the steel sheet ring is including the first spacing portion that is located the portal outside and being located the spacing portion of second of portal inside wall, the fixed plate will the rubber turn over the board compress tightly in first spacing portion.
Preferably, the steel plate ring comprises a plurality of steel plate sections, and the steel plate sections form the steel plate ring surrounding the tunnel portal.
Preferably, the fixing plate is provided with bolt holes, and the fixing plate, the rubber turning plate and the steel plate ring are fixed on the tunnel door through bolts.
Preferably, two bolt seats are arranged on the fixing plate, clamping strips are connected to the bolt seats through bolts, and the clamping strips and the fixing plate clamp the rubber sheet.
Preferably, the width of the fixing plate gradually increases from the opening to the outside.
Preferably, the edge of the inner side wall of the steel plate ring is provided with a protruding rib.
Preferably, the width of the rubber sheet is smaller than that of the rubber turning plate.
Preferably, the thickness of the rubber sheet is smaller than that of the rubber flap.
In summary, compared with the prior art, the invention has the advantages that: the rubber turning plate is matched with the rubber sheet, so that the sealing effect is improved, and the problem that the rubber turning plate at the portal with smaller size is not tightly attached to the shield is solved.

The reference numbers in the figures are as follows:
1. the steel plate comprises a steel plate ring, 11 parts of a first limiting part, 12 parts of a second limiting part, 13 parts of a protruding rib, 2 parts of a rubber turning plate, 3 parts of a fixing plate, 31 parts of bolt holes, 32 parts of bolt seats, 33 parts of clamping strips, 4 parts of rubber sheets and 5 parts of a hole door.
Detailed Description
The invention will be further elucidated with reference to an embodiment in the drawing.
The rubber hinge plate sealing structure suitable for the micro shield as shown in fig. 1 to 3 comprises a steel plate ring 1, a rubber turning plate 2 and a fixing plate 3 which are arranged in sequence, wherein a rubber sheet 4 is arranged on the fixing plate 3. The steel plate ring 1 comprises a first limiting part 11 located on the outer side of the tunnel door and a second limiting part 12 located on the inner side wall of the tunnel door, and the rubber turning plate 2 is pressed on the first limiting part 11 through the fixing plate 3. The steel plate ring 1 comprises a plurality of steel plate sections which can be assembled, the steel plate sections form the steel plate ring 1 surrounding the tunnel portal, and the width of a gap between the steel plate sections is not more than 0.5 cm.
The fixed plate 3 is provided with a bolt hole 31, and the fixed plate 3, the rubber turning plate 2 and the steel plate ring 1 are fixed on the tunnel door through bolts. The bolt holes 31 are strip-shaped holes extending in the axial direction of the portal so as to adjust the position of the bolt. The width of the fixing plate 3 is gradually increased from the opening to the outside. I.e. the fixing plates 3 are of a trapezoidal configuration to ensure that the gap between adjacent fixing plates 3 is sufficiently small.
Two bolt seats 32 are arranged on the fixing plate 3, clamping strips 33 are connected to the bolt seats 32 through bolts, and the clamping strips 33 and the fixing plate 3 clamp the rubber sheet 4. The holding strip 33 is provided with teeth, and the rubber sheet 4 is provided with grooves or through holes which are embedded with the teeth. The width of the rubber sheet 4 is smaller than the width of the rubber turning plate 2, the thickness of the rubber sheet 4 is smaller than the thickness of the rubber turning plate 2, and the rubber sheets 4 with different thicknesses and lengths (the size along the circumferential direction of the tunnel door) can be replaced according to needs so as to supplement gaps caused by folds or gaps of the rubber turning plate 2.
The edge of the inner side wall of the steel plate ring 1 is provided with a raised rib 13, the annular raised rib 13 separates the rubber turning plate 2 in the area from the steel plate ring 1, so that the rubber turning plate 2 is attached to the shield machine as far as possible under the action of the water-soil pressure at the gap, and the rubber turning plate and the rubber sheet 4 on the outer side form a dual waterproof structure.
The above description is only for explaining the present invention and making the present invention complete, but not limiting the present invention, and the skilled in the art can make modifications without inventive contribution to the present embodiment as required after reading the present specification, and these are all modifications without inventive contribution, but are protected by patent laws within the scope of the claims of the present invention.
