Abstract
The utility model discloses a prefabricated standard concrete equipment foundation of a transformer substation, and the prefabricated standard concrete equipment foundation is a prefabricated concrete cube with the side length being 1.2 m. The prefabricated standard concrete equipment foundation is poured by C25 concrete (6), the center on the prefabricated standard concrete equipment foundation is provided with a reverse-quadruple-prismatic-table cup used for pouring a rod piece, the two sides of a cup opening are provided with hoisting rings (5), and a small number of rebars are arranged on the periphery of the cup opening and the bottom of the foundation. The rebars (1) with the diameter being 12 are vertically arranged on the periphery of the cup opening. The rebars (2) with the diameter being 10 annularly arranged on a pile foundation of the bottom of the foundation in the two directions are arranged at the bottom of the foundation. According to the prefabricated standard concrete equipment foundation, uniform industry prefabrication is adopted, construction units purchase finished products, templates can be constant for manufactures due to the standard size, and the kinds of the sizes of the templates can be reduced. The prefabricated standard concrete equipment foundation is reasonable in design, safety of equipment is guaranteed, the safety degree of the construction field is improved, the prefabricated standard concrete equipment foundation can be prefabricated, the construction progress is accelerated, the construction period is shortened, and investment is saved. The prefabricated standard concrete equipment foundation is suitable for the transformer substation equipment foundation.
Description
technical field
The utility model relates to a kind of transformer station prefabricated standard concrete equipment Foundations, belongs to transformer substation foundation construction technique field.
background technology
What at present substation equipment all adopted is Cast-in-place concrete single footing. cast-in-place basis needs on-the-spot formwork cast, and after maintenance after a while, can vertical rod, construction period is longer, and at formwork, between curing time, as rainwater weather, the foundation ditch digging is destroyed by rainwater easily.The size disunity of different equipment Foundations designs, also causes template kind more, increases construction complexity.
summary of the invention
The purpose of this utility model is, the problem that the Cast-in-place concrete single footing adopting according to existing substation equipment exists, the utility model proposes a kind of standardized Prefabricated Concrete basis, and this basis is directly prefabricated in the factory, and water at the scene of noting be used in.
The technical solution of the utility model is, a kind of transformer station of the utility model prefabricated standard concrete equipment Foundations are prefabricated cubes of concrete that a length of side is 1.2m, cast by C25 concrete, center has one for pouring into a mould the cup of falling truncated rectangular pyramids of rod member above, rim of a cup both sides arrange suspension ring, and rim of a cup surrounding and foundation bottom arrange a small amount of reinforcing bar.
The reinforcing bar of described rim of a cup surrounding setting is the reinforcing bar that vertical direction is arranged, the reinforcing bar of horizontal arrangement that has been arranged vertically on reinforcing bar uniform welding.
The reinforcing bar of described foundation bottom setting is the two-way reinforcing bar being circular layout of foundation bottom pile foundation, on the two-way reinforcing bar being circular layout uniform welding the reinforcing bar of horizontal arrangement.
The utility model is little for substation equipment weight difference, and all, in 1.5t left and right, it is 1.2m that basic size is unified in to periphery, and weight of equipment adds that basis deadweight can meet ground requirement for bearing capacity completely.
The utility model adopts factory unified prefabricated, and unit in charge of construction buys finished product, and modular size can make producer's fixed form, reduces template size.
Rim of a cup both sides, the utility model basis arrange suspension ring, after excavation of foundation pit puts in place, with loop wheel machine, basis is put in place, soon can vertical rod, backfill foundation ditch.
The beneficial effects of the utility model are that the utility model is reasonable in design, ensures device security, improves the degree of safety of job site, can manufacture in advance, has accelerated construction speed, shortens construction period, saves investment.
The utility model is applicable to substation equipment basis.

Detailed description of the invention
Detailed description of the invention of the present utility model as shown in Figure 2.
The present embodiment transformer station prefabricated standard concrete equipment Foundations are prefabricated cubes of concrete that a length of side is 1.2m, cast by C25 concrete 6, center has one for pouring into a mould the cup of falling truncated rectangular pyramids of rod member above, rim of a cup both sides arrange suspension ring 5, rim of a cup surrounding and foundation bottom arrange a small amount of reinforcing bar: the two-way reinforcing bar being circular layout 2 of foundation bottom pile foundation, the vertical direction of basis surrounding has been arranged reinforcing bar 1, the reinforcing bar 3 of horizontal arrangement that has been arranged vertically on reinforcing bar 1 uniform welding, on the two-way reinforcing bar being circular layout 2 uniform welding the reinforcing bar of horizontal arrangement.
The present embodiment is in when application, bed course 9 C10 concrete; Cup 1.2 cement mortar screeding layers at the end; After excavation of foundation pit puts in place, with loop wheel machine, basis is put in place, soon can vertical rod, backfill foundation ditch, by C30 concrete back-grouting, fills the eminence to rim of a cup end face 80mm.
The present embodiment transformer station prefabricated standard concrete equipment Foundations according to existing national rule specification GB50007-2011 " Code for design of building " carry out Punching Shear, shearing resistance, bending resistance three aspects: design checking computations are determined.Basis requires to be placed on old soil layer, and bearing capacity of foundation soil is more than or equal to 40kN/m
