Abstract
The utility model relates to the surge shaft of trash rack is equipped in one kind.The purpose of the utility model is to provide a kind of structures it is simple, easy for construction in be equipped with trash rack surge shaft.The technical solution of the utility model is: the surge shaft of trash rack is equipped in a kind of, it is characterized by: being equipped with the trash rack structure of covering surge shaft downstream water outlet in the surge shaft, trash rack structure includes vertical trash rack and top trash rack, which is made of the vertical trash rack perpendicular to pressure regulation bottom and the top trash rack being connected at the top of vertical trash rack between the borehole wall of surge shaft downstream side.The utility model is suitable for hydraulic and hydroelectric engineering field.
Description
Technical field
The utility model relates to be equipped with the surge shaft of trash rack in one kind, it is suitable for hydraulic and hydroelectric engineering field.
Background technique
For stopping river dirt, the water inlet for being usually placed in power station arranges trash rack at "-" type, blocks
The dirty generally rectangular structure of grid.But since power station is first to excavate diversion tunnel, last water inlet is chock blasting molding, is existed
Once rock is filled in, mouth of a river explosive forming is bad or deep water construction is difficult, and not only grid slot is difficult to construct, but also takes other to remedy and arrange
Applying also can be relatively difficult, thus this type engineering water inlet arrangement trash rack be it is relatively difficult, to trash rack arrangement and
Pattern is put forward new requirements.
Summary of the invention
Technical problem to be solved by the utility model is: in view of the above problems, provide that a kind of structure is simple, construction
The surge shaft of trash rack is equipped in convenient.
The technical scheme adopted by the utility model is being equipped with the surge shaft of trash rack in a kind of, it is characterised in that: the tune
The trash rack structure of covering surge shaft downstream water outlet is equipped in kill-job, trash rack structure includes that dirt is blocked at vertical trash rack and top
Grid, the trash rack structure is by the vertical trash rack perpendicular to pressure regulation bottom and is connected at the top of vertical trash rack and surge shaft downstream
Top trash rack composition between the borehole wall of side.
The vertical trash rack is arranged to the arc-shaped that a center of circle is located at the vertical trash rack downstream.
The vertical trash rack is put together by several vertical trash rack screens for being perpendicularly fixed at pressure regulation bottom, vertically
Trash rack screen is rectangular configuration, and angle is 7 ° between the adjacent two vertical trash rack screen.
The vertical trash rack bottom and two sides through pre-embedded steel slab, stud and nut be individually fixed in surge shaft bottom and
The two sides borehole wall.
It is fixedly connected between the top trash rack and the surge shaft borehole wall through pre-embedded steel slab, stud and nut.
The beneficial effects of the utility model are: trash rack is set in surge shaft by the utility model, solves power station
Water inlet trash rack be difficult to construct and remedy difficult problem.The trash rack global shape semicircular in shape of utility model, cloth
Seated position and shape are relatively new, are conducive to trash rack normal mounting, use and safeguard.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the present embodiment.
Fig. 2 is the top view of the present embodiment.
Fig. 3 is the A-A cross-sectional view of Fig. 2.
Fig. 4 is the B of Fig. 2 to expanded schematic diagram.
Specific embodiment
As shown in Figure 1 to 4, the present embodiment is the surge shaft that trash rack is equipped in a kind of, is equipped with covering in surge shaft and adjusts
The trash rack structure of kill-job downstream water outlet, so that the water of upstream has to pass through trash rack structure when flowing to surge shaft downstream.
Trash rack structure includes vertical trash rack and top trash rack in the present embodiment, and the trash rack structure is by perpendicular to tune
Dirt is blocked at the vertical trash rack 1 of 6 bottom of kill-job and the top being connected between vertical 1 top of trash rack and the 6 downstream side borehole wall of surge shaft
Grid 2 form.
The vertical trash rack screen 101 that vertical trash rack 1 is perpendicularly fixed at 6 bottom of surge shaft by 4 pieces is put together, vertically
Trash rack screen 101 is rectangular configuration, and angle is 7 ° between adjacent two vertical trash rack screen 101, by vertical trash rack screen
The vertical trash rack 1 that split is formed is arranged to the arc-shaped that a center of circle is located at the vertical trash rack downstream.
Top trash rack 2 is the top trash rack grid being arranged in a one-to-one correspondence by 4 pieces with vertical trash rack screen 101 in this example
The semicircular structure that plate 201 pieces together, vertical 101 top of trash rack screen is fixed in trash rack screen 201 one end in top, another
End is fixed on 6 borehole wall of surge shaft in vertical 1 downstream side of trash rack.
Vertical 1 bottom of trash rack and two sides are individually fixed in the bottom of surge shaft 6 through pre-embedded steel slab 3, stud 4 and nut 5
With the two sides borehole wall.It is fixedly connected between top trash rack 2 and 6 borehole wall of surge shaft through pre-embedded steel slab 3, stud 4 and nut 5.
The construction method of the present embodiment is as follows: 6 bottom of surge shaft starts to install vertical trash rack 1, passes through civil engineering pre-buried steel
Plate 3 and stud 4 are fixed on trash rack on concrete block of wood, are then tightened with nut 5；It is installed Deng whole vertical trash rack 1
Bi Yihou, then start installation top trash rack 2, the same mode of top trash rack 2 is mounted on concrete block of wood.
