Abstract

A substation prefabricated concrete bulk water (1), the bulk water is composed of precast concrete, structural reinforcement, asphalt sand (5) and silicone weather-resistant adhesive (4), the structural reinforcement is set in the prefabricated concrete, and the asphalt sand (5) fills the joints Between the two concrete sprinklers, the silicone weather-resistant adhesive is applied to the surface of the sprinkler joints. The width B of the sprinkling water is 0.8-1m, and the length is 0.6-1.2m; the four sides are chamfered, the chamfering radius R is 35mm, and the thickness H is 100mm; a 20mm deformation joint is left between the sprinkling water and the building (structure). A 5mm seam is left between the scattered water, the lower part of the seam is filled with asphalt sand, and the surface is sealed with 10mm thick silicone weather-resistant adhesive. The utility model can effectively solve the phenomena of water cracking and fracture caused by temperature stress brought about by uneven compaction of backfill soil or super-long structure. The utility model is not only applicable to each substation in the national grid system, but also applicable to other engineering industries, and has strong applicability.

Description

A kind of transformer station precast concrete aproll

Technical field

The utility model relates to a kind of transformer station precast concrete aproll, belongs to electrical equipment technical field.

Background technology

In order to protect the wall base not to be subjected to rain erosion, the exterior wall surrounding of being everlasting is made ground outward-dipping domatic, so as with the Water in Rainwater Drainage of roofing at a distance, be called aproll, this is one of effective measures of protection house foundation.

In existing national grid substation project is built; the cast-in-situ concrete aproll is because structure foundation excavates, and the inhomogeneous or reason thermal stresses brought due to overlength of backfill compaction often there will be crackle, phenomenon of rupture even, has not both had drainage; not attractive in appearance again, affect impression.

Summary of the invention

The purpose of this utility model is that in order to solve cast-in-situ concrete aproll cracking phenomena, the utility model discloses a kind of transformer station precast concrete aproll.

The technical solution of the utility model is, change the cast-in-situ concrete aproll into the precast concrete aproll, and every aproll length L is 0.6～1.2m, thick H is 100mm, in join distributing bar, four limit chamferings, stay between every aproll the seam 5mm, the 1:1 sand asphalt cementation of fissures is adopted in the seam bottom, surperficial silicone weather resistant glue sealing.

A kind of transformer station of the utility model precast concrete aproll is comprised of precast concrete, distributing bar, sand asphalt and silicone weather resistant glue, distributing bar is located in precast concrete, the sand asphalt cementation of fissures is between two block concrete aprolls, and silicone weather resistant glue is coated in the aproll seam surface.

The beneficial effects of the utility model are, aproll adopts prefabricated units, and have the following advantages: a large amount of members are completed batch production in factory, and production efficiency is higher; Its secondary member is produced with mould, and process conditions are better, reduced the impact of personnel's variable on quality, improved quality level, and the quality of production is not subjected to the impact in weather and season; The 3rd is that prefabricated units are easy to realize modularization, standardization, large-scale production, and price is relatively low; The 4th is the impact that reduces surrounding enviroment, and the mud that produces in the manufacturing process of site concrete, noise and waste material are larger to surrounding environment influence; The 5th is effectively to have solved the inhomogeneous or thermal stresses that bring due to overlength of backfill compaction to cause aproll cracking, phenomenon of rupture.

The utility model is because form compare is succinct, and the making of its mould is also relatively simple, and size can be unified, can be general in state intrasystem each transformer station of net, have good compliance and benefit.

The specific embodiment

The specific embodiment of the present utility model as depicted in figs. 1 and 2.

Precast concrete aproll 1 adopts the C25 clear-water concrete, and the loose B of aproll is 0.8～1m, and when the inorganization draining, aproll is loose can emit 0.2～0.3m by the cornice line, length L is generally 0.6～1.2m, four limit chamferings, and chamfer radius R is 35mm, thickness H is 100mm, in mix anti-crack fiber, distributing bar.Stay the 20mm deformation joint between aproll and building, stay seam 5mm between every prefabricated aproll, 1:1 sand asphalt 5 cementation of fissures are adopted in the seam bottom, surperficial 10 thick silicone weather resistant glue 4 sealings of ㎜, and other ways are with the cast-in-situ concrete aproll.

More than be the construction installation method of precast concrete aproll.
