Abstract
The invention discloses a method for preventing a joint of jacking pipes from being broken, and belongs to the technical field of foundation engineering construction. The method comprises the following steps that 1, a groove in a front end connector of one jacking pipe is cleaned; 2, a cork block is adhered to the groove in the front end connector of the jacking pipe through power glue, and the glue is flatly applied inside the jacking-pipe connector; and 3, the jacking pipe is pushed to a front jacking pipe until a clamping groove in the rear end of the front jacking pipe is connected with the groove in the front end of the jacking pipe. According to the method for preventing the joint of the jacking pipes from being broken, stress is buffered in the pushing process of two contact surfaces by arranging the cork block, and this is due to the fact that the cork block can relieve the situation that concrete breakage produced by too much contact stress of the two rigidity concrete surfaces in the pushing process of the jacking pipes; the situation of breakage and cracking caused by too much stress of the pipe contact surfaces is prevented from being happened, and resource waste of the jacking pipes is avoided.
Description
Technical field
The invention belongs to basic engineering construction technical field, particularly relate to a kind of push pipe joint that prevents and damaged method occurs.
Background technique
At present in urban road construction, along with being on the increase of municipal engineering, how the pipe-networks engineering being embedded in underground being reduced in construction the impact of road traffic, periphery structure and nearby residents is had higher requirement.In order to reduce the impact on ground environment to greatest extent, in the laying and transformation of underground utility, no-excavation construction method is more and more to come into one's own.Be widely used in urban road pipe network improvement project as the pipe jacking construction technique adopted in recent years in trenchless technology, but in jacking construction process, very heavy item and push pipe surface of contact, due to the effect of jacking force, easily cause the breakage of push pipe surface of contact, even ftracture, cause the wasting of resources of push pipe.
How to prevent push pipe from breakage occurring in pushing tow process by arranging corresponding material or solved by technological means between push pipe joint, since push pipe application, be the focus that technician inquires into always.
Summary of the invention
A kind of push pipe joint that prevents is the object of the present invention is to provide damaged method to occur, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, present invention employs following technological scheme:
Prevent push pipe joint from a damaged method occurring, comprise the following steps:
1) a push pipe front tab groove is cleaned out;
2) by super glue, cork block is bonded at this push pipe front tab groove, and flat deposited inside this push pipe joint;
3) by this push pipe to the last period push pipe pushing tow until push pipe the last period rear end draw-in groove therewith push pipe front end groove connect.
Preferably, the width of groove is 8-10cm.
Preferably, cork block thickness is 5-10mm.
Compared with prior art, beneficial effect of the present invention is as follows:
The present invention is by arranging cork block, make two surface of contact in pushing tow process, stressedly to be cushioned, because it is excessive and produce concrete breakage that cork block can alleviate push pipe two rigid concrete face contacts in the process of pushing tow, the situation that present invention, avoiding the stressed excessive and damaged cracking in tube contacts face occurs, and avoids the waste of push pipe resource.
Accompanying drawing explanation
Fig. 1 is the front end sectional drawing of push pipe.
Fig. 2 is the profile of push pipe.
Embodiment
Below in conjunction with embodiment, optimal way of the present invention is described in further detail.
As depicted in figs. 1 and 2, there is damaged method in a kind of push pipe joint that prevents, comprises the following steps:
1) cleaned out at push pipe 1 front tab groove 11 place, the width of groove 11 is 8-10cm.
2) by super glue, cork block 2 is bonded at this push pipe 1 front tab groove 11 place, and flat deposited inside this push pipe 1 joint.
3) by this push pipe 1 to the last period push pipe 1 pushing tow until push pipe 1 the last period rear end draw-in groove 12 therewith push pipe 1 front end groove 11 connect, cork block 2 thickness is 5-10mm.
The present invention proposes a kind of push pipe joint that prevents and damaged method occurs, when municipal engineering are on the increase, pipe jacking construction technique is widely used, and the risk that jack and push pipe 1 surface of contact easily cause the breakage of push pipe 1 surface of contact to ftracture in the process of pushing tow hinders the further development of pipe jacking construction technique always, the present invention pastes cork block 2 at existing push pipe 1 front tab groove 11 place, alleviates that push pipe 1 two rigid concrete face contacts in pushing tow process are excessive and concrete that is that produce is damaged by cork block 2.
Above embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technological scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
Claims (3)
1. prevent push pipe joint from a damaged method occurring, it is characterized in that, comprise the following steps:
1) push pipe (1) front tab groove (11) place is cleaned out;
2) by super glue, cork block (2) is bonded at this push pipe (1) front tab groove (11) place, and flat deposited inside this push pipe (1) joint;
