Abstract
The utility model discloses a fabricated cable trench body of a transformer substation. The cable trench body mainly consists of sections of waterproof reinforced concrete channel bodies with U-shaped cross sections, wherein, the channel bodies are connected in sequence; a flange section and a concave connecting groove which can be connected in an end to end manner are arranged at the front end and the back end of each channel body respectively, and form a front-back lapping groove and tongue; a rubber strip is mounted between channel bodies which are connected in an end to end manner; the cross section of the rubber strip is in the shape of a flat gasket connected by two rings; and the rubber strip is arranged on the peripheral wall surface of the flange section and clamped between the flange section and the concave connecting groove. Compared with the prior art, the cable trench body has the advantages that the construction period is shortened, the pavement cost is reduced, the work efficiency is improved, the labor productivity is increased, and the appearance quality is greatly improved; and the cable trench body has better popularization using value.
Description
Technical field
The utility model relates to the universal transforming plant assembly type cable slot body of a kind of transformer station, belong to the design field in transformer station, power plant.
Background technology
At present the cable trough of the above transformer station of 220kV designs, and according to the height of burried depth, load size, level of ground water, makes forms such as brick, plain concrete, armored concrete cable slot body respectively, to satisfy the requirement of transformer station, power plant cable laying.But along with the development of China's electric utility, the cable slot body of this field fabrication also is faced with the problem of following several respects:
1) on-the-spot masonry project amount is big, and the engineering time is long: with the 220kV power transformation example of doing, be converted to the 1.1x0.85m cable slot body, the about 1100m of its total length.Brick cable slot body budgetary estimate expense is 625 yuan/m3 (pressing sky in the ditch, down together), and the construction period is 35 days; Plain concrete cable slot body budgetary estimate expense is 820 yuan/m3, and the construction period is 25 days; Armored concrete cable slot body budgetary estimate expense is 1120 yuan/m3, and the construction period is 30 days;
2) above cable slot body all needs interior exterior plaster, the also outer water-repellent paint of doing of brick, plain concrete cable slot body, and the time cost is many; Use more material, resource is taken many; The most frequently used brick, plain concrete cable slot body regular meeting on soft soil foundation has sedimentation excessive and problem cracking takes place;
3) present State Grid Corporation of China's transformer substation construction, be to carry out by " amphitypy one is changed " standard, promptly environmentally friendly, resource-conserving, industrialization, in addition along with the fast development of electric utility, the construction period of transformer station also is required to shorten greatly, full assembled transformer station will be a developing direction, but the field fabrication cable slot body will hinder applying of full assembled transformer station.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of construction requirements that can comply with full assembled transformer station to cable slot body, install, thereby can satisfy the assembly type cable slot body of the transformer station of transformer station's cable laying requirement by prefabrication production, job site assembled.
The purpose of this utility model is finished by following technical solution, described transforming plant assembly type cable slot body, and the waterproof armored concrete ditch body that it is mainly taken the shape of the letter U by a section cross section joins successively and forms.
Described ditch body rear and front end be respectively arranged with can before and after the flange sections and the recessed access slot that join, and constitute front and back overlap joint tongue and groove, between the ditch body that front and back join the rubber bar is installed.
Described rubber sliver transvers section is the plain cushion sheet that is linked to each other by two circles, and it is placed on the peripheral wall surfaces of flange sections, is sandwiched between flange sections and the recessed access slot.
Can be when the utility model is installed by the water proof structure and the material of junction, forms a kind of can prefabrication, on-the-spot installation, be the clear-water concrete presentation quality, can constitute the full assembly type cable slot of whole antiseepage again.
After adopting the utility model " transforming plant assembly type cable slot body " design and product utilization, since brought into play simultaneously on-the-spot direct assembling, again do not need again in exterior plaster, do water-repellent paint outward, therefore aspect transformer station's cable slot body scene duration, can taper to 10 days, total duration generally can save 15 days, about 10%; The Technological Economy aspect considers that the minimizing of labour cost, the expense of whitewashing waterproof material reduce, after the increase of installation cost, and the about 650 yuan/m3 of its budgetary estimate expense maintains an equal level with brick cable trough economy commonly used; Presentation quality is greatly improved, and labor productivity improves, and application value is preferably arranged.

Fig. 3 is the local structure for amplifying schematic diagram of the I among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.Figure 1 shows that the ditch body plan structure schematic diagram that is paved on the bottom surface, and Fig. 2 is the cross-sectional structure schematic diagram of ditch body.Described transforming plant assembly type cable slot body, the waterproof armored concrete ditch body 1 that it is mainly taken the shape of the letter U by a section cross section joins successively and forms.Described ditch body 1 rear and front end be respectively arranged with can before and after the flange sections 2 and the recessed access slot 3 that join, and constitute front and back overlap joint tongue and groove, between the ditch body 1 that front and back join rubber bar 4 is installed.
Shown in Figure 3, described rubber bar 4 cross sections are the plain cushion sheet that is linked to each other by two circles, and it is placed on the peripheral wall surfaces of flange sections 2, is sandwiched between flange sections 2 and the recessed access slot 3.
The method for paving of transforming plant assembly type cable slot body described in the utility model, at first on the C15 of routine plain concrete cushion layer, the dried sand 100mm that lays cement is thick, is used for the leveling of the assembly type cable slot body of back installation; Be connected together mutually by the overlap joint tongue and groove successively before and after then that a section is the prefabricated ditch body, and be lined with the rubber bar in the joint.
Before described two ditch bodies join, be pressed on the flange sections periphery wall of a ditch body wherein earlier with rubber bar three limits, be inserted in then in the recessed access slot of another ditch body, and make top line become smooth shape, carry out the welding and the installation of cable bearer again in the cable slot body after the ditch body joins.
Make: adopt the customization steel mold, zone, precasting yard ground on-site, on-the-spot batch production is made, the moisture-heat preservation maintenance; It is that specialized factory decides processing that two P outward appearances are met water microdilatancy rubber bar.
Install: (1) at first on the C15 of routine plain concrete cushion layer, the dried sand 100mm that lays cement is thick, is used for the leveling of the assembly type cable slot body of back installation; (2) utilize the standing P200 in building site to excavate transportation and installation in the airport; Make full use of the overlap joint tongue and groove of this assembly type cable slot body utility model when (3) connecting, install up and down, simultaneously of the present utility model pair of P outward appearance met water microdilatancy rubber bar three limits and compress, top line is if any trickle horizontal problem, with rubber hammer hammering leveling; (4) pea gravel concreten looks for the mechanical perforate in slope and back to place drainage pipe.
