Technical Field
The utility model relates to a construction technical field is a composite set who is used for push pipe entrance to a cave stagnant water particularly.
Background
No matter the pipe jacking construction goes out of the hole or enters the hole, a certain gap is reserved between the pipe joint and the hole, and the hole water stopping device is a through-wall hole which is arranged in the working pit and the receiving pit. It has the main functions as follows: firstly, thixotropic slurry injected into the outer wall of the pipeline is prevented from leaking from a hole, and the pipeline is lubricated and loses friction resistance; and secondly, the underground water and soil loss can be prevented at the same time, so that the ground subsides and the surrounding buildings are damaged. Therefore, the hole water stopping device plays an important role in the construction of the top pipe.
The traditional water stopping device is installed in a blocking mode through the embedded steel ring, the rubber plate and the pressing plate, installation accuracy mainly depends on proficiency and responsibility of field operators, effective guarantee cannot be achieved, water stopping at a hole is invalid, water gushing and mud entering happen sometimes, and meanwhile the device is low in recovery utilization rate.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to solve the above-mentioned problem that exists among the prior art, provide a modular stagnant water composite set, the simple installation, the entrance to a cave stagnant water is efficient, and the work progress risk reduces the hand labor volume, reduces occupational hazard.
In order to achieve the purpose, the combined device for stopping water at the pipe-jacking hole is characterized by comprising an installation base, wherein the installation base is made of an annular plate, an unthreaded hole and a threaded hole are formed in the installation base, and the installation base is fixedly connected with the side wall of a foundation pit through the unthreaded hole; the adjusting pressure plates are distributed on the periphery of the mounting base at equal intervals, 1-shaped grooves are formed in the adjusting pressure plates, and the adjusting pressure plates can move along the radial direction of the mounting base; and the rubber plate is arranged between the mounting base and the adjusting pressure plate and is connected with the mounting base through a bolt.
Preferably, the cross section of the adjusting pressure plate is in a half-square shape, and the middle part of the adjusting pressure plate is hollow.
Preferably, a centering plate is arranged between the rubber plate and the adjusting pressure plate, and the centering plate is used for pressing the rubber plate on the mounting base.
Preferably, the inner circle part of the rubber plate is provided with a reinforcing belt which is of a spherical structure.
Preferably, the bottom of the mounting base is provided with an annular groove, and a sealing ring is arranged in the annular groove.
Compared with the prior art, the utility model, its advantage lies in:
1. the modularized combination device is convenient to install and disassemble, and the installation efficiency is improved;
2. the back-and-forth disassembly and assembly of the rubber plate are reduced, the installation abrasion is avoided, and the service life of the rubber plate is prolonged;
3. the modularized combination device is connected through the base, so that the positioning precision is improved;
4. and the integral installation reduces the working strength of operators.
Drawings
FIG. 1 is a schematic view of the structure of the device of the present invention;
FIG. 2 is a schematic structural diagram of the device of the present invention;
in the figure: 1. the foundation pit side wall 2, the mounting base 3, the sealing ring 4, the adjusting pressure plate 5, the centering plate 6, the bolt 7 and the rubber plate.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, and the structure and principle of the present invention will be clear to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The first embodiment is as follows: as shown in fig. 1 and 2, the utility model provides a composite set for push pipe entrance to a cave stagnant water mainly includes five components of mounting base, sealing washer, rubber slab, centering plate and adjusting plate, and five components pass through stud and connect into a whole module, form combination formula watertight fittings.
The mounting base is made of a whole annular plate, the upper part of the mounting base is provided with a unthreaded hole and a threaded hole, and the mounting base is connected and fixed with the side wall of the foundation pit through the unthreaded hole, is a mounting base of the whole device and ensures the water stopping effect; the threaded holes are used for connecting various components in the device; meanwhile, in order to prevent the gap between the side wall of the foundation pit and the mounting base from leaking, the bottom of the base is provided with two annular grooves for mounting a sealing ring, and the local leakage caused by the unevenness of the side wall of the foundation pit is eliminated.
Adopt centering plate and two closing device of regulation clamp plate, the centering plate provides the location for the rubber slab, ensures that the rubber slab tightly presses on the mounting base, and when the clamp plate loosened radial regulation, the clamp plate can not become flexible under the fixed of centering plate simultaneously, avoids the seepage.
The circle portion in the rubber slab has the strengthening band, and the similar spherical structure of strengthening band structure is through locally strengthening the circle in the rubber slab, avoids causing the rubber slab to lose efficacy too early because of fatigue wear because of circle and tubular product contact friction in the rubber slab.
The adjusting pressure plate is provided with a 1-shaped long groove, the length of the 1-shaped groove is half of the clearance between the inner diameter of the reserved hole and the outer diameter of the pipe, the 1-shaped groove can be adjusted along the radial direction of the pipe, the clearance is reduced, and the rubber plate at the hole is prevented from being overturned by high water pressure.
Example two: the construction method of the water stop combined device comprises the following steps:
1. construction preparation;
2. reserving a hole in the side wall of the foundation pit, and embedding a connecting bolt hole;
3. the device is assembled and connected in a workshop, and the integrity of the rubber plate is checked;
4. after the foundation pit is manufactured and before the jacking pipe starts, the combined water stopping device is installed at the opening of the hole through the installation base;
5. the gap between the hole and the pipe is changed by adjusting the pressure plate;
6. the gap of the pressing plate is continuously adjusted in the jacking process, so that the rubber plate is prevented from being overturned;
7. after the pipe jacking is communicated, the water stopping combined device is recovered;
8. and the combined water stopping device is maintained for waiting for the next construction.
