Abstract
The utility model discloses a laying structure of a cable crossing river channel, which is characterized by comprising a guide hole channel. The guide hole channel is formed under the river channel through a horizontal orientation drilling machine, a metal pipe and a cable line dragged in through the horizontal location drilling machine is arranged in the guide hole channel, two ends of the metal pipe are fixed at the external positions of two ends of the guide hole channel, and the cable line penetrates through the metal pipe to be connected with an external line. The laying structure is not affected by anchoring of ships, effectively ensures safety operation of the cable line, is quick in construction speed, low in cost and convenient to construct, operate and maintain, does not affect city attractive appearance of cities and is especially suitable for penetrating through rivers longer than 500m.
Description
Technical field
The utility model relates to a kind of laying structure of cable, is specially the laying structure that a kind of cable is crossed over the river course.
Background technology
The 220kV Voltage Cable Lines Construction is through the river time, if river broad (more than the 500m) generally needs to transfer cable to overhead transmission line and crosses over the river, or adopts extra large cable to lay.It is attractive in appearance to adopt overhead transmission line leap river to influence the city, operation maintenance inconvenience.It is very high to adopt extra large cable to lay expense, and the construction operation is difficulty.
Summary of the invention
To the problems referred to above, the utility model provides a kind of easy construction, speed fast, and expense is low, and the river course laying structure is crossed in operation maintenance cable easily.
The utility model is that the technical scheme that its technical problem of solution is adopted is:
A kind of cable is crossed over the river course laying structure; Comprise the guiding duct that forms in the below, river course through horizontal directional drilling machine; Guiding is provided with metal tube and the cable line of pulling into through horizontal directional drilling machine in the duct; The external position place at guiding two ends, duct is fixed at the two ends of metal tube, and cable line passes metal tube and is connected with the circuit of outside.
As preferred embodiment, said cable line is the bundle pipes that many cable duct tube colligations become, and cable is distributed in the cable duct tube.
As preferred embodiment, be provided with at least one in the said bundle pipes and be used for subsequent use blank pipe.
As preferred embodiment, the internal diameter of said cable duct tube is greater than 1.5 times of the cable external diameter.
As preferred embodiment, said guiding duct is for carrying out the guiding duct of multistage reaming gained through replacing horizontal directional drilling machine drill bit.
As preferred embodiment, the aperture in said guiding duct is 1.2 to 1.5 times of metal tube.
As preferred embodiment, said guiding duct is in the riverbed, river course below 5 meters.
The beneficial effect of the utility model is: the utility model forms the guiding duct below the river course under the cooperation of horizontal directional drill, further in this guiding duct, lay metal tube and cable line again, and this laying structure is not cast anchor by ship to be influenced; Effectively guaranteed the safe operation of cable line; Speed of application is fast, and expense is low, and construction and operation maintenance are convenient; It is attractive in appearance not influence the city, is particularly useful for passing through the above river of 500m.
Description of drawings
Further explain below in conjunction with accompanying drawing and embodiment:
Fig. 1 is the laid processes prior step sketch map of the utility model;
Fig. 2 is the laid processes later steps sketch map of the utility model.
Embodiment
See figures.1.and.2, a kind of cable of the utility model is crossed over the river course laying structure, comprises through the horizontal directional drilling machine 2 guiding duct that 1 below forms in the river course, and for the influence that guarantees not cast anchor by ship, the guiding duct generally is in 1 riverbed, river course below 5 meters.Guiding is provided with metal tube and the cable line of pulling into through horizontal directional drilling machine 2 in the duct, and the external position place at guiding two ends, duct is fixed at the two ends of metal tube, and cable line passes metal tube and is connected with the circuit of outside.During practical application, metal tube generally adopts steel pipe, and cable line then is the bundle pipes that many cable duct tube colligations become, and cable is distributed in the cable duct tube.For the needs of maintenance and expansion, be provided with at least one in the bundle pipes and be used for subsequent use blank pipe, do not place cable in this blank pipe, when needs, draw again and establish cable.For the convenience of laying, the internal diameter of cable duct tube should be greater than 1.5 times of cable external diameter.Likewise, the aperture in guiding duct should be preferably 1.2 to 1.5 times of metal tube.
For the smooth formation in the duct that guarantees to lead, the guiding duct should be through changing the guiding duct that horizontal directional drilling machine 2 drill bits 3 carry out multistage reaming gained.The structure in this duct can guarantee that engineering can carry out smoothly, reduces the engineering difficulty.
See figures.1.and.2, the laid processes of the utility model preferably adopts following steps:
(1) according to planning, navigation channel, hydraulic department requirement, the starting point and the terminal point of selected both sides, river, and the minimum-depth of cable river crossing;
(2) arrange horizontal directional drilling machine 2 in starting point, drill bit 3 is drilled into terminal point by planned course 4, form the guiding duct;
(3) bit change 3 more adopts multistage reaming, guiding aperture, duct is extended to intends 1.2～1.5 times that lay metal tube;
(4) metal tube 5 is all welded in the terminal point side, length is slightly larger than starting point path length to terminal;
(5) utilize horizontal directional drilling machine 2 that metal tube is pulled in the guiding duct, the metal tube 5 of starting point and terminal point is carried out anchoring;
(6) cable duct tube (MPP pipe, internal diameter is greater than 1.5 times of the outside diameters of cable) is all connected (hot melt butt joint) in the terminal point side, length is slightly larger than steel pipe length;
(7) become bundle pipes by 4 cable duct tube colligations,
(8) utilize small-sized horizontal directional drilling machine 2 or hauling machine with colligation the bundle pipes after good pull in the metal tube 5;
(9) cable is pulled in the cable duct tube, laid 1 cable in the every cable duct tube, it is subsequent use to reserve 1 blank pipe.
Above-mentioned construction method speed of application is fast, and expense is low, and construction and operation maintenance are convenient, are particularly useful for passing through the above river of 500m.
The execution mode of the utility model is not restricted to the described embodiments, as long as it reaches the technique effect of the utility model with essentially identical means, all should belong to the protection range of the utility model.
