Abstract
The invention relates to a transformer substation assembly type cable trench body and a pavement method. The transformer substation assembly type cable trench body is mainly formed by connecting a plurality of sections of water-proof reinforced concrete trench bodies with U-shaped transverse cross-sections in sequence; a flange section and a groove which can be connected in tandem are respective arranged at the front and the rear ends of the trench body, a tongue-and-groove lapped back and forth is formed, and a rubber strip is installed between the trench bodies connected in tandem; the pavement method comprises the following steps: the cement bonded sand with thickness of 100 mm is paved on the conventional C15 plain concrete cushion course, and is used for the equalization of the assembly type cable trench body installed later; then the sections of the well prefabricated trench bodies are connected together through the lap-joint tongue-and-groove in sequence, and the rubber strip is underlaid at the connected point; and compared with the prior art, the invention has the advantages of reduced construction period, reduced pavement cost, improved work efficiency and labor productivity, greatly improved appearance quality and better popularization and application values.
Description
Technical field
What the present invention relates to is universal assembly type cable slot of a kind of transformer station and installation method, belongs to the design-build technical 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/m
3(pressing sky in the ditch, down together), the construction period is 35 days; Plain concrete cable slot body budgetary estimate expense is 820 yuan/m
3, the construction period is 25 days; Armored concrete cable slot body budgetary estimate expense is 1120 yuan/m
3, 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 objective of the invention 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 by prefabrication production, job site assembled, thereby can satisfy the transforming plant assembly type cable slot body and the method for paving of transformer station's cable laying requirement.
The objective of the invention is to finish by following technical solution, described transforming plant assembly type cable slot body, the waterproof armored concrete ditch body that it mainly is the U type by a section cross section joins successively and forms, it is characterized in that described armored concrete 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 armored concrete 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.
A kind of method for paving of transforming plant assembly type cable slot as mentioned above, at first on the C15 of routine plain concrete cushion layer, the dried sand 100mm that lays cement is thick for it, 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 armored concrete ditch body, and be lined with the rubber bar in the joint.
Before described two armored concrete ditch bodies join, earlier with rubber bar three limits be pressed in wherein-the flange sections periphery wall of ditch body on, be inserted in then in the recessed access slot of another armored concrete 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 armored concrete ditch body joins.
Water proof structure and material that can be by the junction when the present invention installs, 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 body of whole antiseepage again.
After adopting the present invention's " 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, the about 650 yuan/m of its budgetary estimate expense
3, fair with brick cable trough economy commonly used; Presentation quality is greatly improved, and labor productivity improves, and application value is preferably arranged.
