Description
Technical field
The present invention relates to pipeline construction field, more particularly to a kind of construction method for passing through existing roadbed pipeline.
Background technology
The existing pipeline for passing through existing roadbed, due to can not be affected greatly to existing roadbed, it is impossible to using large scale computer
Tool equipment is excavated, and typically uses hand excavation's roadbed, is influenceed by the commuting skylight of vehicle phase big, it is necessary to several manually time-consuming 1-2
Roadbed is passed through in the ditching of skylight phase, and the method cost is high, time-consuming more, and is had a great influence by skylight encashment ratio and Window time, not really
It is more to determine factor, often occur because skylight cancel and caused by workmen's work holdup phenomenon.
The content of the invention
It is time-consuming more it is an object of the invention to overcome hand excavation's roadbed cost in the presence of prior art high, and by
Skylight encashment ratio and Window time have a great influence, and uncertain factor is more, often occur because skylight cancel and caused by workmen's nest
A kind of above-mentioned deficiency of work phenomenon, there is provided construction method for passing through existing roadbed pipeline.
In order to realize foregoing invention purpose, the invention provides following technical scheme：
A kind of construction method for passing through existing roadbed pipeline, comprises the following steps：
A, in roadbed side, ground excavates downwards operating pit；
B, at least one hole is bored to the opposite side of the roadbed in the operating pit；
C, pipe, the end-enclosed of the pipe are penetrated into each hole；
D, after the pipe is set in place, backfilled into the operating pit, complete construction.
Wherein, the operating pit is excavated in step A downwards and exposes the ground under the roadbed, and punching is worn in this place
The roadbed；By the end-enclosed of the pipe in the step C, soil enters inside the pipe during avoiding poling, shadow
Ring the follow-up threading in pipe.It should be noted that the sky required for the size adaptation puncher work of operating pit described herein
Between.
Using a kind of construction method for passing through existing roadbed pipeline of the present invention, drilling construction application mini-plant,
Roadbed will not be affected greatly, not influence existing line normal operation, it is not necessary to cash the skylight phase and construct again, efficiency of construction
More existing artificial ditching is passed through roadbed and greatly improved, and effectively reduces construction cost, this method step is simple, easy to operate, is easy to
Promotion and implementation.
Preferably, in the step B, be first molded the hole with puncher, then with reamer by the aperture in the hole expand to
The caliber of the pipe needed for adaptation.
Preferably, when need through the caliber of the pipe be more than 80mm when, first with diameter 50-60mm reamers counterboring institute
State hole, then the hole described in the reamer counterboring of the adaptation caliber.
In this way, avoid using relatively high power motor during disposable enlarged diameter hole, bring larger vibration to influence
The roadbed.
Preferably, 1-2m often is crept into the puncher, sets extension bar to be further continued for drilling on the puncher.
Preferably, appropriate water is injected by injector with the puncher boring procedure.
In this way, the soil tunneled the puncher or reamer front end needs in drilling process
Softening, beneficial to the vibration reduced in equipment attrition and reduction work progress.
Preferably, in the step D, the operating pit is backfilled using the woven bag for being filled with sandstone, is easy to subsequently wear electricity
Cable takes out the end that sandstone bag finds the pipe in time when constructing.
Preferably, in the step C, the end of the pipe is blocked with gauze or polybag cladding.
Preferably, after performing the step D, dug at the tube end of the operating pit offside and connect hole, expose institute
Tube end is stated, is easy to subsequently thread in the tube, and hole is connected with being filled with described in the woven bag backfill of sandstone, is easy to follow-up
The end that sandstone bag finds the pipe is taken out when wearing cable construction in time.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, set with a kind of construction method for passing through existing roadbed pipeline of the present invention, drilling construction using small-sized
It is standby, roadbed will not be affected greatly, not influence existing line normal operation, it is not necessary to cashed the skylight phase and construct again, construct
The more existing artificial ditching of efficiency is passed through roadbed and greatly improved, and effectively reduces construction cost, and this method step is simple, easy to operate,
It is easy to promotion and implementation；
2nd, with a kind of construction method for passing through existing roadbed pipeline of the present invention, when the caliber is more than 80mm,
Hole described in 50-60mm reamer counterborings is first used, then with hole described in the reamer counterboring of the caliber is adapted to, in this way,
Avoid using relatively high power motor during disposable enlarged diameter hole, bring larger vibration to influence the roadbed；
3rd, with a kind of construction method for passing through existing roadbed pipeline of the present invention, with the puncher boring procedure
In appropriate water is injected by injector, in this way, by the puncher or the reamer in drilling process
Front end needs the soil softening tunneled, beneficial to the vibration reduced in equipment attrition and reduction work progress.
