Abstract
The invention relates to an environmentally-friendly slope-attaching type trash rack and a building method thereof and belongs to a structural style of trash rack arrangement. The trash rack comprises a hoist chamber. The contact portions of trash rack piers and a mountain are of step shapes. An included angle alpha between the trash rack piers and the horizontal plane is from 60 degrees to 80 degrees. A connecting beam is connected between the two trash rack piers. Each trash rack pier is provided with a trash rack gate groove. The connecting beam is connected with the mountain in a contacting mode. The trash rack piers or the connecting beam and the mountain are fixedly connected through anchoring rods. Trash rack gates are connected with the trash rack gate grooves in a sliding mode. The trash rack has the advantages of being simple in structure, reliable in operation, and suitable for the geography with the natural side slope grade of 60 degrees to 80 degrees, natural slope covering layers and the geological condition of shallow rock mass weathering. The trash rack achieves the purpose of trash holding, attention is paid to the combination of the trash rack and the natural mountain slope, the requirement of the structural functionality is met, the purpose of ecological environmental protection is achieved, and the trash rack has the good application prospect.
Description
Technical field
The present invention relates to the structural shape that a kind of trashrack is arranged, a kind of trashrack pastes slope layout pattern specifically, is applicable to the independent water inlet of arranging, is greater than the trashrack of arranging along slope in 60 ° of landform in the gradient.
Background technology
The function of trashrack is to prevent that dirt from entering water inlet, thereby affects the normal operation of the hydraulic turbine.The layout pattern of trashrack is decided by that the pattern of water inlet and power station quote the size of flow, and local weather conditions, reservoir level excursion, trashrack block minimum dimension and the cleaning method etc. of dirt.Can be arranged in the plane two kinds of straight line and semicircles (often for polygon), on facade, can be vertical or tilt.Trashrack also can be arranged to according to maintenance demand fixed or movable.
Water inlet mostly was absolute construction in the past, and horn mouth is arranged in massif outside, so arranges, can avoid large scale tunnel excavation, but also occurred some problems simultaneously.As: water inlet leading edge length is longer, around it, can assemble a large amount of dirts; For the needs of architecture basics and stability of slope, carry out dig on a wide area; Between trashrack and gate shaft, adopt access bridge to be connected, cleaning transport dirt inconvenience etc.
Summary of the invention
The invention provides a kind of environment-friendly type slope sticking type trashrack structure and construction method thereof, longer to solve the water inlet leading edge length that existing layout exists, around it, can assemble a large amount of dirts, the problem of cleaning transport dirt inconvenience.
The technical scheme that the present invention takes is:
Comprise hoist chamber, trashrack pier becomes stepped with massif contact site, this trashrack pier and horizontal plane angle α are 60 °～80 °, between two trashrack piers, be connected with contact beam, on each trashrack pier, there is trashrack gate slot, this contact beam is connected with massif contact, and this trashrack pier or contact beam are fixedly connected with by anchor pole respectively with massif, and trashrack door and this trashrack gate slot are slidably connected.
The construction method of described environment-friendly type slope sticking type trashrack structure, comprises the following steps:
Water inlet diffuser is arranged in massif, adopts three expandings, and top board angle of flare β is 9 ° ~ 11 °, and planar expanded angle γ is 4 ° ~ 6 °, and the ratio of width to height of the port size of trashrack is 0.6～1, its excavation width 8 ~ 10m;
(1) carry out foundation excavation according to side slope form and structural configuration: this grade of side slope is chosen between 60 °～80 °, the trashrack Dun Chu that need are arranged excavates into groove, stepped on groove facade, depth of groove 1.0m ~ 2.5m, ladder tread 1.5m, the high 10m that gets of ladder;
(2) after excavation, domaticly should meet stability requirement: should squeeze into and be connected anchor pole to domatic rock mass with structure contact portion;
(3) along side slope, by physical dimension, installation form, assembling reinforcement on anchor pole, concreting, builds out trashrack pier and contact beam, and the groove of trashrack pier both sides and contact beam upside is adopted to plain concrete backfill;
(4) in the trashrack body gate slot of trashrack pier, trashrack door is installed.
Advantage of the present invention is: arrange along side slope, design and natural, ecological are better merged, and trashrack pier is in tilted layout along side slope, reduces slope excavation, reduces construction investment; Reduce the disturbance of massif side slope, for there being unfavorable architectonic side slope, by consolidation process, can make side slope more firm; Intimate parallel with both sides massif side slope, do not stop current, reduce dirt and collect water inlet leading edge, stop up trashrack, affect power station operation.
The present invention is simple in structure, reliable, is applicable to natural grade of side slope at the landform of 60 ° ~ 80 °, the geological conditions that natural hillside covering layer and Weathering Zones of Igneous Rock are more shallow.This invention integrates the advantages such as ecology, environmental protection, easy construction, Stability Analysis of Structures, applied range; solve and block dirty object simultaneously in emphasis; also focus on the combination with natural massif side slope; realize the requirement that meets structure function; the object of ecological, environmental protective again; improve engineering economy, be conducive to environmental protection and water and soil conservation, there is good application prospect.
