The utility model discloses on current shield tail brush seal structure's basis, increase the further sealed effect of strengthening of curtain cloth rubber slab, at the in-process that push bench and section of jurisdiction are tunneled forward, guarantee to laminate all the time airtight between curtain cloth rubber slab and the section of jurisdiction, reduced the risk that appears gushing water and gush sand among the part complex stratum environment, improved the security in the work progress.
Description
Technical Field
The utility model relates to a shield tunnel contact passageway construction technical field, concretely relates to can improve push pipe method contact passageway of tunnelling security with sealing device that starts.
Background
Shield structure contact channel generally sets up in the middle of two tunnels, become a passageway of setting between two tunnels, play the intercommunication, effects such as drainage and fire prevention, pipe jacking method contact channel is short with its construction period, with low costs, the security is high, environmental impact is little, a great deal of advantages such as application scope is wide, extensively be applicable to the interval of soft soil geology subway shield, highway tunnel, the underground pipe gallery, the side play structure and the contact channel engineering of projects such as electric power tunnel, not only use in the middle of the subway construction, still promote to deep drainage tunnel, construction fields such as municipal administration piping lane and underground space UNICOM. Along with the continuous maturity of contact passageway construction technology, the stratum environment that push bench construction faced also more and more complicated, in general contact passageway construction, the sealed mode that adopts shield tail brush and shield tail grease of gap between push bench and the steel sleeve, nevertheless in facing high infiltration, contained confined water stratum, shield tail brush can take place wearing and tearing along with advancing of push bench, section of jurisdiction, reduces sealed effect to the risk that causes to gush water and gush sand in the work progress.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a push pipe method contact passageway is with sealing device that starts strengthens the sealed effect of push bench at the beginning tunnelling in-process, reduces the risk that gushes water and gush sand in the work progress.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a starting sealing device for a pipe jacking method communication channel comprises a pipe jacking machine, a pipe piece and a starting steel sleeve which is arranged on the upper portion of the pipe jacking machine in parallel along a tunneling direction, wherein a sealing structure is arranged between the pipe jacking machine and the starting steel sleeve, the sealing structure comprises a plurality of shield tail brushes which are uniformly arranged in gaps between the starting steel sleeve and the pipe jacking machine, and the sealing structure further comprises:
and one end of the sealing plate is fixedly connected with the end face of the starting steel sleeve in the tunneling direction, and the other end of the sealing plate extends and expands along the tunneling direction and is tightly attached to the outer wall of the pipe jacking machine or the pipe piece.
Furthermore, the sealing plate is a cord fabric rubber plate and is fixedly connected with the originating steel sleeve through a bolt structure and an arc sliding plate.
Preferably, the arc sliding plate comprises a plurality of arc blocks which are spliced with each other, and the arc blocks are provided with waist-shaped through holes for fastening bolts to pass through.
According to the technical scheme provided by the utility model, on the basis of current shield tail brush seal structure, increase the further sealed effect of strengthening of curtain cloth rubber slab, at the in-process that push bench and section of jurisdiction are tunneled forward, guarantee to laminate all the time airtightly between curtain cloth rubber slab and the section of jurisdiction, reduced the risk that appears gushing water and gush sand among the part complex stratum environment, improved the security in the work progress.

FIG. 2 is a schematic view of the arc slide plate of the present invention;
in the figure: 1. a pipe jacking machine; 2. a duct piece; 3. originating a steel casing; 4. a shield tail brush; 5. a sealing plate; 6. a circular arc slide plate; 7. a waist-shaped through hole.
Detailed Description
A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.
The originating sealing device for the pipe jacking method communication channel shown in figure 1 comprises a pipe jacking machine 1, a pipe piece 2 and an originating steel sleeve 3 which is arranged on the upper part of the pipe jacking machine in parallel along the tunneling direction, wherein a sealing structure is arranged between the pipe jacking machine and the originating steel sleeve, the sealing structure comprises a plurality of shield tail brushes 4 and sealing plates 6 which are uniformly arranged in gaps between the originating steel sleeve and the pipe jacking machine, one end of each sealing plate is fixedly connected with the end face of the originating steel sleeve in the tunneling direction, and the other end of each sealing plate extends and expands along the tunneling direction and is tightly attached to the outer wall of the pipe jacking machine or the pipe piece.
The sealing plate of the preferred embodiment adopts the cord fabric rubber plate, and in order to ensure that the cord fabric rubber plate is firmly installed, the cord fabric rubber plate is fixedly connected with the originating steel sleeve through the bolt structure and the arc sliding plate 6, the arc sliding plate shown in fig. 2 comprises a plurality of arc blocks which are mutually spliced, waist-shaped through holes 7 for the fastening bolts to pass through are formed in the arc blocks, the diameter of the inner ring of the arc sliding plate is slightly smaller than that of the originating steel sleeve, and the fact that each blocking sliding plate can be further tightened inwards through the waist-shaped through holes is ensured, so that the supporting capacity of the back of the cord fabric rubber plate is improved.
In specific use, it is noted that the curtain cloth rubber plate is deformed when being extruded, and the maximum transverse distance of the extending part of the curtain cloth rubber plate is set according to the actual construction condition, so that the damage caused by the mutual extrusion of the end part of the curtain cloth rubber plate and the root part of the shield tail brush is prevented; secondly, before the pipe jacking machine starts, grease or other lubricating grease should be applied to the two sides of the cord fabric rubber plate, so that the friction force of the pipe jacking machine or the pipe piece in the tunneling process is reduced.
The above-mentioned embodiments are only to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
