Description

Push pipe coupling assembling

Technical Field

The utility model relates to the technical field of jacking pipes, in particular to a jacking pipe connecting assembly.

Background

The pipe jacking technology is a trenchless tunneling pipeline laying construction technology for municipal construction. The pipe-jacking construction is a construction method of an underground pipeline developed after the shield construction, which does not need to excavate a surface layer and can pass through roads, railways, rivers, ground buildings, underground structures, various underground pipelines and the like. The pipe jacking construction is to push the tool pipe or the heading machine from the working well to the receiving well through the soil layer by means of the thrust of the main top oil cylinder, the relay between the pipelines and the like.

At present, the pipe jacking is generally sealed by pressing a sealing material, but in pipe jacking construction, the pipe jacking part presses the sealing material due to overlarge deviation of the axis of a pipeline, interface dislocation and uneven gaps, so that the problem of leakage is caused due to the fact that the gaps exist between the two pipe jacking parts is caused, and therefore the pipe jacking connecting assembly is provided.

Disclosure of Invention

Aiming at the defects in the prior art, the utility model provides a jacking pipe connecting assembly.

The utility model provides the following technical scheme: the utility model provides a push pipe coupling assembling, includes the push pipe, front end metal port and the rear end metal port that are used for the butt joint are installed respectively to the front and back end of push pipe, two symmetrical distribution's boss are all installed to the inboard of front end metal port and rear end metal port, install the guide pillar that is used for the push pipe correction on the boss of front end metal port, just offer on the boss of rear end metal port and be used for guide pillar male hole.

Preferably, the end face of the rear end metal port is provided with a groove for sealing inwards, and the end face of the front end metal port protrudes forwards and is contacted with the groove of the end face of the rear end metal port to press the sealing ring.

Preferably, a steel reinforcement cage is arranged in the jacking pipe, and two ends of the steel reinforcement cage are welded on the front end metal port and the rear end metal port respectively.

Preferably, the boss is arc-shaped, has no edges and corners, and is integrally formed with the inner side surfaces of the front end metal port and the rear end metal port.

Preferably, the diameter of the hole is matched with the diameter of the guide post, so as to correct the position of the jacking pipe.

Compared with the prior art, the utility model has the following beneficial effects:

this push pipe coupling assembling installs front end metal port and rear end metal port respectively in the front and back end of push pipe so that connect to utilize the guide pillar to insert as the tie point, make push pipe and preceding top butt joint, and keep both to contact completely, can not appear the skew, make two push pipes compress tightly sealing material, avoid appearing the clearance between two push pipes, cause the problem of revealing.

In addition, when the guide posts on the front end metal port are inserted into the boss holes in the rear end metal port during butt joint, if the guide posts cannot be in butt joint, the guide posts are only propped against the rear end metal port, the push pipes cannot be damaged, the butt joint can be carried out again through adjustment, and therefore damage to the push pipes during butt joint is avoided.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model;

fig. 2 is a schematic bottom view of the fig. 1 embodiment of the present utility model.

In the figure: 1. jacking pipes; 2. a front end metal port; 3. a rear end metal port; 4. a boss; 5. a guide post; 6. a hole; 7. a groove.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, a technical solution of the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings of the embodiments of the present disclosure, and detailed descriptions of known functions and known components are omitted from the present disclosure in order to avoid unnecessarily obscuring the concept of the present disclosure.

Referring to fig. 1-2, a pipe jacking connection assembly includes a pipe jacking 1, a front end metal port 2 and a rear end metal port 3 for butt joint are respectively installed at the front end and the rear end of the pipe jacking 1, a reinforcement cage is arranged in the pipe jacking 1, and two ends of the reinforcement cage are welded on the front end metal port 2 and the rear end metal port 3 respectively, so that the pipe jacking 1, the front end metal port 2 and the rear end metal port 3 are connected, and are not easy to break away from each other, and a water stop belt is arranged at the joint of the front end metal port 2 and the rear end metal port 3 and the pipe jacking 1, so that the problem of infiltration can be avoided.

The end face of the rear end metal port 3 is provided with a groove 7 for sealing inwards, the end face of the front end metal port 2 protrudes forwards and is contacted with the groove 7 of the end face of the rear end metal port 3 to press the sealing ring, and when two jacking pipes 1 are connected, the front end metal port 2 of one jacking pipe 1 is inserted into the rear end metal port 3 of the other jacking pipe 1 to press the sealing material.

Two symmetrically distributed bosses 4 are arranged on the inner sides of the front end metal port 2 and the rear end metal port 3, a guide post 5 for correcting the jacking pipe 1 is arranged on the boss 4 of the front end metal port 2, a hole 6 for inserting the guide post 5 is formed in the boss 4 of the rear end metal port 3, the diameter of the hole 6 is matched with the diameter of the guide post 5 and is used for correcting the position of the jacking pipe 1, when the two jacking pipes 1 are positioned on the same straight line, the guide post 5 of the front end metal port 2 of one jacking pipe 1 can be inserted into the hole 6 of the rear end metal port 3 of the other jacking pipe 1, so that the two jacking pipes 1 are accurately connected, when the jacking pipe 1 is inserted, if the previous jacking pipe 1 is offset, the guide post 5 is difficult to insert, and when the edge-covered jacking pipe 1 is installed, the position is correct.
