Abstract
The utility model discloses a kind of powerhouse of hydropower station upstream and downstream wall body structures, wall including bent columns (1) and its bottom, the wall includes the different thick wall body section (3) of thickness and thin wall section (2), is bent columns (1) above thick wall body section (3).The thickness that the utility model passes through the wall segment of rational design framed bent column bottom, keep the wall segment thickness identical or smaller as the section long edge size of column, and the thickness of wall body at the not position of pillar is thinned, the usage amount of walls concrete material can be saved, the duration of concreting is saved；The space that lower part auxiliary power house can also be increased provides the facility of bigger for the laying of equipment and the passage of personnel.
Description
Technical field
The utility model is related to be related to a kind of structure that wall locally thickeies, belong to the hydro-structure in hydraulic and hydroelectric engineering
Field.
Background technology
Powerhouse of hydropower station structure generally can be divided into three component parts：Superstructure, substructure and generator bearing knot
Structure.Superstructure includes mainly workshop framework, each floor plate, crane girder Roof system and building enclosure etc., and substructure is main
There are draft tube, spiral case and machine pier and underwater wall, pier etc., bottom plate of the which part as factory building foundation.Workshop framework lower end can
On wall or it is directly embedded into basement rock under fixed mass concrete, tail water gate pier, upper water under water.Framed bent upstream column is generally fixed
In head bay wall wall top, downstream bent columns are generally fixed at the top of tail water gate pier, and workshop downstream wall is poured with tail water gate pier using whole
The thick wall built.
In the design and construction of existing powerhouse of hydropower station, upstream and downstream wall generally uses the wall of equal thickness, and wall
Body thickness is identical or bigger as the section long edge size of column, does so, and is bound to cause the waste of material (such as concrete), can also make
At the waste of lower secondary hall space.
Invention content
The technical problems to be solved in the utility model is：Powerhouse of hydropower station upstream and downstream wall body structure is provided, wall can be saved
The usage amount of concrete material saves the duration of concreting；The space of lower part auxiliary power house can also be increased, be the laying of equipment
And the passage of personnel provides the facility of bigger.
The technical solution of the utility model is as follows：
A kind of powerhouse of hydropower station upstream and downstream wall body structure, including bent columns and its wall of bottom, the wall include thickness
Different thick wall body sections and thin wall section are spent, is bent columns above thick wall body section.Here thick wall body section is a pair of with bent columns one
It answers, and without bent columns above thin wall section.
The thickness of wall body of the thick wall body section be more than or equal to bent columns section long edge size, i.e., in the section of bent columns compared with
That section of long length of side.
The thickness of wall body of the thin wall section is less than the section long edge size of bent columns.
The longitudinal length of the thick wall body section is more than or equal in the section short side dimension of bent columns.
Vertical applied force reinforcing bar in the bent columns extends in thick wall body section.
The thick wall body section is dabbing process face, i.e. thick wall body section and bent columns interface with bent columns boundary surface concrete
Concrete should carry out dabbing processing.
It is a kind of structure that wall locally thickeies in the utility model in essence, by the part for rationally designing framed bent column bottom
The thickness of wall mainly achieves following two purposes：One, the quantities of walls concrete has been saved, concrete is saved
The duration poured；Two, the space of the auxiliary power house beside wall is increased convenient for the laying of equipment and the passage of personnel.According to normal
Way is advised, thickness of wall body is not due to what the Force Calculation of itself obtained, but because the column dimensions on top are excessive, pillar is solid
It is scheduled on wall top portion, and therefore entire thickness of wall body is artificially increased, although this way also meets structural requirement, is caused
The unnecessary property of quantities increases, and has also accordingly increased the duration of concreting.
Compared with prior art, as follows the advantages of the utility model：By the wall segment for rationally designing framed bent column bottom
Thickness, keep the wall segment thickness identical or bigger as the section long edge size of column, and the wall at the not no position of pillar is thinned
Body thickness can save the usage amount of walls concrete material, save the duration of concreting；Lower part auxiliary power house can also be increased
Space, the facility of bigger is provided for the laying of equipment and the passage of personnel.Construction method involved by the utility model is simple,
It is easily mastered, it is easy to spread, there is certain practical value.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic diagram of Section A-A in Fig. 1；
Fig. 3 is the schematic diagram of section B-B in Fig. 1；
In figure：1- bent columns, the thin wall sections of 2-, 3- thick wall body sections.
Specific implementation mode
Further describe the utility model below in conjunction with the accompanying drawings, but claimed range be not limited to it is described, it is all to adopt
The technical solution formed with equivalent substitution or equivalent transformation, all falls within the protection domain required by the utility model.
As shown in Figure 1, a kind of powerhouse of hydropower station upstream and downstream wall body structure, including bent columns 1, thin wall section 2 (do not thicken
Wall), thick wall body section 3 (part thickeies wall).
The thickness of thick wall body section 3 (part thickeies wall) is more than or equal to the section long edge size of bent columns 1.Thin wall section 2
The thickness of (not thickening wall) is less than the section long edge size of bent columns 1.The longitudinal length of thick wall body section 3 (part thickeies wall)
More than or equal in the section short side dimension of bent columns 1.The vertical applied force reinforcing bar of bent columns 1 is inserted into thick wall body section 3, and (part thickeies wall
Body) in anchorage length should meet code requirement.Thick wall body section 3 (part thickeies wall) is answered with 1 boundary surface concrete of bent columns
Carry out dabbing processing.Bent columns 1 should meet serviceability limit state checking computations and ultimate limit states checking computations.Thin wall section
2 (not thickening wall) should meet serviceability limit state checking computations and ultimate limit states checking computations.(the part of thick wall body section 3
Thicken wall) serviceability limit state checking computations and ultimate limit states checking computations should be met.
The structure that the above part thickeies wall has applied in the level-one powerhouse of hydropower station construction of pillow dam.Pillow Ba Yijishui
It is provided with outlet structure at the top of Power Plant 1#, 2# unit downstream auxiliary power house, to increase framed bent integral strength, under 1#, 2# unit
Trip auxiliary power house upstream and downstream side is all made of reinforced concrete wall, and downstream side uses truss column between host.Wherein, under 1#, 2# unit
It is 3.5m that trip auxiliary power house upstream side wall EL.619.83m~EL.601.65m, which has the position thickness of wall body of truss column, without framework
The position thickness of wall body of column is 2m, and thickness of wall body has significant difference.Pillow dam level-one power station first operating unit generator operation so far,
Live whole works well.
