Abstract
The invention discloses a laying method for a jacking pipe. The laying method comprises the steps of step s1, laying the jacking pipe in a position which is at least five meters under the ground; step s2, establishing observing points, which are within two meters from the ground surface, at the two ends of the jacking pipe through high-density polyethylene pipes along a preset slope in an extension manner; and step s3, establishing cable observing wells on the two observing points respectively. By adoption of the laying method, a cable shaft arranged on the opening of the jacking pipe can be avoided; operation below three meters is not required; a cable observing well is only needed to be added at the position, which is two meters from the ground, when the movable high-density polyethylene pipes climb the slope to the position, so that the construction cost is lowered while the safety of operators is improved; the cable observing well is adopted to replace the cable shaft, so that a right-angle bending is avoided in laying the cable; the requirement of a cable turning radius is satisfied; and meanwhile, the cable laying difficulty is also lowered.
Description
Technical field
The present invention relates to technical field of electric power, in particular to the laying method of a kind of push pipe.
Background technology
Along with the process of modernization of the country, urban construction step is increasingly faster, various municipal pipelines
, stacking crisscross in underground is gathered, and ground civic building gets more and more, power engineering
During middle cable laying, excavation construction makes road quality variation, welding, gives the life of people simultaneously
Live, work brings inconvenience, and construction cost is more and more higher.Pipe-jacking technology well solves
The problems referred to above, also bring new problem and challenge simultaneously.
Power cable engineering often uses top when boring facilities such as getting over some railways, highway, river
Manifold technology, for ensureing above ground structure or the stability on road surface, push pipe is typically built and is located in the ground 5
Below meter.Present situation push pipe is to meet laying and overhauling requirement of cable, the most all can be at push pipe two
End arranges cable shaft, by the cable shaft at two ends by the electricity of the cable in push pipe Yu direct-burried section
Cable is attached.This kind of scheme can make cable form two right angles in cable shaft, adds
Cable laying difficulty, the cost of cable shaft is higher simultaneously, adds construction budget.
Summary of the invention
The technical problem to be solved is, it is provided that a kind of push pipe that can reduce cost
Laying method.
Therefore, technical scheme is as follows:
A kind of laying method of push pipe, including:
Step s1,5 meters, underground, depth below lays push pipe；
Step s2, is prolonged along the gradient preset by high density polyethylene pipe at the two ends of described push pipe
Extend the point of observation within 2 meters of ground of distance；
Step s3, builds cable respectively at two described points of observation and observes well.
It is provided with concrete cushion in the lower section of described high density polyethylene pipe.
Described high density polyethylene pipe is externally provided with concrete pack.
By the invention it is possible to avoid push pipe mouth to arrange cable shaft, it is not necessary to work below 3 meters
Make, only need to increase a cable at movable high density polyethylene pipe climbing extremely liftoff two meters and observe
Well, decreases construction costs, reduces construction costs and adds the safety of workmen
Property；Observe well with cable and instead of cable shaft, avoid when cable laying and quarter bend occurs,
Meet the requirement of turning of cable radius, also reduce the difficulty of cable laying simultaneously；This with
Climbing mode is tieed up with the method that push pipe part is connected with direct-burried section cable is easy to later operation
Protect, decrease fault odds；This kind of method short construction period, integrated cost is low, peace
Full performance is good.
Accompanying drawing explanation
Fig. 1 is the engineering schematic diagram of the laying method of push pipe according to embodiments of the present invention.
Detailed description of the invention
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.Need
Illustrating, in the case of not conflicting, the feature in embodiments herein and embodiment can
To be mutually combined.
As it is shown in figure 1, the laying method of push pipe according to an embodiment of the invention, including:
Step s1,5 meters, underground, depth below lays push pipe 1；
Step s2, at the two ends of described push pipe 1 by high density polyethylene pipe 2 along default slope
Degree extends to the point of observation within 2 meters of ground of distance；
Step s3, builds cable respectively at two described points of observation and observes well 3.
It is provided with concrete cushion in the lower section of described high density polyethylene pipe 2.
Described high density polyethylene pipe 2 is externally provided with concrete pack.
By the invention it is possible to avoid push pipe mouth to arrange cable shaft, it is not necessary to work below 3 meters
Make, only need to increase a cable at movable high density polyethylene pipe climbing extremely liftoff two meters and observe
Well, decreases construction costs, reduces construction costs and adds the safety of workmen
Property；Observe well with cable and instead of cable shaft, avoid when cable laying and quarter bend occurs,
Meet the requirement of turning of cable radius, also reduce the difficulty of cable laying simultaneously；This with
Climbing mode is tieed up with the method that push pipe part is connected with direct-burried section cable is easy to later operation
Protect, decrease fault odds；This kind of method short construction period, integrated cost is low, peace
Full performance is good.
In sum, present disclosure is not limited in the above embodiments, this area
Technical staff can propose other embodiment within technological guidance's thought of the present invention, but this
Within kind embodiment is included in the scope of the present invention.
