Abstract

The invention discloses a method for rapidly inserting a cable into a sleeve, which belongs to a construction method for paving the cables and aims to achieve convenience of construction, high efficiency, low cost and capability of inserting the cable into the plastic sleeve. The method comprises the following specific steps of: drilling a threading hole on a pipe wall close to the inlet end of a line pipe; inserting a guide rope into the threading hole, and connecting the guide rope with a piston arranged in the line pipe; introducing compressed air from the inlet end of the line pipe until the piston is pushed out of the outlet end of the line pipe; leading the tail end of the guide rope out of the inlet end of the line pipe, connecting the guide rope with a pulling rope, and pulling the rope end of the pulling rope to the outlet end of the line pipe by using the guide rope; and fixedly connecting the tail end of the pulling rope with the end of the cable, and pulling the end of the cable out of the outlet end of the line pipe by using the pulling rope. The method has a plurality of advantages of convenience of construction, labor saving, high efficiency, low cost and the like, and is ideal for inserting the cable into the protection sleeve.

Description

The quick poling method of cable

Technical field: the present invention relates to a kind of cable be penetrated the method for protective casing, belong to the construction method of cable laying line.

Background technology: along with the development of urban service, the cable of infrastructure such as universal demand electric power, telecommunications is gone into operation in the ground; In order to protect cable, in burying the work progress of cable underground, require usually cable is penetrated in the plastic bushing.At present, generally all be to utilize bamboo pole to come the pilot cable line to penetrate plastic bushing, though operation sequence is simple,, thereby there is defective because this method is more original:

1) because of the restriction of bamboo pole length, can only segmentation wear; Not only efficient is lower, and the consumption of pipe joint is also more, construction cost is higher;

2) big, the poling of the resistance that wears many cables simultaneously difficulty relatively;

3) wear in the process because bamboo pole need occupy bigger space, therefore need to increase the diameter of plastic bushing, thereby cause construction cost to rise;

4) because bamboo pole is hard, the relatively difficulty of turning, therefore require the radius of turn of plastic bushing bigger, increased the consumption of difficulty of construction and plastic bushing.

Summary of the invention: at the above-mentioned defective that exists in the prior art, the present invention aims to provide a kind of easy construction, efficient height, the quick poling method of cable that cost is low.

To achieve these goals, the present invention by the following technical solutions, concrete steps are as follows:

1) boring through wires hole near on the tube wall of spool arrival end;

2) strop being passed above-mentioned through wires hole is connected with the piston that places described spool;

3) arrival end from spool feeds compressed air, until described piston is released from the port of export of spool;

4) end of described strop is drawn with pull rope from the arrival end of spool be connected, the fag end of described pull rope is pulled to the port of export of spool by strop;

5) end of pull rope is fixedlyed connected with the termination of cable, the termination of described cable is pulled out from the port of export of spool by this pull rope.

On the basis of technique scheme, through wires hole is obliquely installed along the direction of motion of piston.

Compared with the prior art, the technique scheme that the present invention adopts has plurality of advantages, makes a concrete analysis of as follows:

1) owing to substitute bamboo pole with pull rope, therefore every section poling distance can be prolonged significantly, has both improved efficiency of construction, reduced again pipe joint consumption, reduced construction cost;

2) substitute bamboo pole with pull rope, become the pulling force of the reasoning of bamboo pole into pull rope, therefore easy to operate, laborsaving;

3) substitute bamboo pole with pull rope and can also overcome the bamboo pole big defective that takes up space, thereby make the plastic bushing of same diameter can hold more or thicker cable, reduced construction cost;

4) because pull rope is soft, so turning resistance is less, and the radius of turn of plastic bushing also can reduce thereupon, not only convenient construction, but also save the consumption of plastic bushing.

Description of drawings:

Fig. 1 is the operation schematic diagram of strop poling in the work progress of the present invention;

Fig. 2 is the operation schematic diagram of pull rope poling in the work progress of the present invention;

Fig. 3 is the operation schematic diagram of cable poling in the work progress of the present invention.

Among the figure: spool 1 piston 2 strops 3 through wires holes 4 compressed air hoses 5 pull ropes 6 cables 7

Embodiment: the invention will be further described below in conjunction with accompanying drawing and specific embodiment:

Shown in Fig. 1～3, concrete steps are as follows:

1) bores through wires hole 4 at tube wall place near spool 1 arrival end;

2) strop 3 being passed through wires hole 4 is connected with the piston 2 that places spool 1;

3) with the arrival end of compressed air hose 5 insertion spools 1, feed compressed air promotion piston 2 and travel forward, deviate from from the port of export of spool 1 until this piston;

4) extract compressed air hose 5, the end of strop 3 is drawn from the arrival end of spool 1; Then strop 3 is connected with pull rope 6, the fag end of pull rope 6 is pulled to the port of export of spool 1 by strop 3;

5) end of pull rope 6 is fixedlyed connected with the termination of cable 7, the termination of cable 7 is pulled out from the port of export of spool 1 by this pull rope 6.

Above-mentioned be among the embodiment, in order to reduce the resistance of strop 3 in the poling process, through wires hole 4 preferably is obliquely installed along the directions of motion of piston 2.

Claims

1. quick poling method of cable is characterized in that concrete steps are as follows:

1) bores through wires hole at tube wall place near the spool arrival end;

2. the quick poling method of cable according to claim 1, it is characterized in that: through wires hole is obliquely installed along the direction of motion of piston.
