Abstract
The invention provides a combined foundation of a framework compressed column and an enclosure in a transformer substation. A framework foundation and the lower part of a lower barricade foundation of the enclosure are arranged in a combined manner and are integrally cast to form the combined foundation. In order to avoid affecting respective use functions, an A-shaped rod framework column is reliability connected with the combined foundation through an embedded bolt on one side of the combined foundation, and in consideration of the overall vertical face effect outside the enclosure and the smooth water drainage inside and outside the substation, the appearance of the part, exposed out of the ground, of a barricade and other barricades are processed uniformly on the other side of the combined foundation, and construction column expansion joints are arranged at two ends of the combined foundation to enable the two ends of the combined foundation to be separated from other enclosures to avoid cracking of a wall body; the integrally cast foundation bears the loads of a compressed framework and the enclosures at the same time, so that safety and reliability are achieved, the size between the framework and each enclosure is reduced, the effective stress of an enclosure foundation is reduced, the project investment is saved, and the construction is convenient.
Description
Technical field
The present invention relates to framework compression column in the transformer station and the commbined foundations of enclosure wall, belong to the infrastructure technical field of transformer station.
Background technology
Substation Design is after adopting unified general module, the interior floor space of enclosure wall becomes a unalterable quota and must not break through, yet different sizes is taken up an area on the basic arrangement form of various geological conditions demands and basis, and depositing the most fat natural ground single footing at limited space lining becomes a stubborn problem.Shown in Figure 1, A font bent structure is generally adopted on outlet structure top in the transformer station, all two posts of A word bar were established separately the single footing during natural ground in the past, analyze according to A word bar truss column actual loading, near enclosure wall lateral column basis pressurized least favorable, near station equipment lateral column basis tension least favorable, basic engineering need consider resistance to plucking and anti-pressure ability; Enclosure wall basis way is the inside and outside retaining wall in the station enclosure wall basis of holding concurrently.By traditional design, enclosure wall basis and the disengagement of framework basis to be arranged, the distance between framework and the enclosure wall is subjected to basis size restriction fully; If characteristic value of foundation bearing capacity is 100kPa, backfill 1.0m is dark in standing, 110kV framework center pillar adopts the single footing size to need 2.2m (wide) X2.8m(long) X2.2m(is dark), reserving A word pole-footing opens, the framework center line must guarantee 3139 do not collide apart from each basis of guarantee with the enclosure wall center line, consider that again operation side and enclosure wall basis in use are subjected to the stress diffusion of framework basis to produce differential settlement and cause the factors such as enclosure wall cracking, approximately need the 3.8m space can realize framework basis and enclosure wall and lower retaining wall smooth construction and use, and transformer station's general design criterion module 110kV framework and enclosure wall only leave 3.0m.Need repeatedly demonstration explanation and need review activities authorizations at different levels in case break through universal design transformer station enclosure wall, program is loaded down with trivial details and affect programming.If do not increase the enclosure wall inside dimension, then can't stop the space that framework single footing and retaining wall foundation break away from fully in the narrow and small enclosure wall line, therefore this binomial basis of ingenious reasonable Arrangement becomes the difficult point of power transformation engineering design.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of energy to strengthen basic anti-pressure ability, solve in the enclosure wall of site underground foundation and arrange phenomenon narrow, that collide, realize saving investment, reduce land used, do not break through State Grid Corporation of China's universal design and take up an area framework compression column in the transformer station of the purposes such as unalterable quota and the commbined foundations of enclosure wall.
The objective of the invention is to finish by following technical solution, framework basis and bottom, enclosure wall lower retaining wall basis are united layout and carried out the whole formation commbined foundations of watering, for not affecting use function separately, side in commbined foundations reliably is connected A word bar truss column with the basis by pre-embedded bolt, opposite side considers that the inside and outside draining of the outer whole facade effect of enclosure wall and station is unobstructed, with barricade unified processing of part outward appearance way and all the other place barricade ways of basseting, and throw off to avoid wall crazing at the commbined foundations two ends by method and all the other enclosure walls of establishing the constructional column shrinkage joint.
The present invention calculates and the field practice experience by theory, draw conventional 110kV pressurized truss column and enclosure wall load similar, therefore can be with this two basis unite and arrange and form integral casting foundation, basis after whole the watering is born pressurized framework and enclosure wall load simultaneously, safe and reliable, more compressed the size between framework and the enclosure wall, reduced the effective stress on enclosure wall basis, saved construction investment, easy construction.
Description of drawings
Fig. 1 is existing conventional 110KV framework foundation layout plan.
Fig. 2 is 110KV framework foundation layout plan of the present invention.
Fig. 3 is the structural representation of commbined foundations retaining wall of the present invention.
The specific embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: Fig. 2, shown in 3, the present invention unites framework basis 1 and 2 bottoms, enclosure wall lower retaining wall basis layout and carries out the whole formation commbined foundations 3 of watering, for not affecting use function separately, side in commbined foundations 3 reliably is connected A word bar truss column 4 with the basis by pre-embedded bolt, opposite side considers that the inside and outside draining of the outer whole facade effect of enclosure wall and station is unobstructed, with barricade unified processing of part outward appearance way and all the other place barricade ways of basseting, and throw off to avoid wall crazing at the commbined foundations two ends by method and all the other enclosure walls of establishing the constructional column shrinkage joint.
The invention provides a kind of new approaches, namely adopt rationally whole watering (framework and retaining wall foundation) of underground foundation, structure base when solving land area and can't the expand problem of colliding, eliminate the side effects such as differential settlement that stress difference is brought between adjacent foundation, simultaneously do not affect original appearance effect, effectively control transformer station's expropriation of land.
