Abstract
The utility model provides a protective structure at the top of a shore tower type water inlet, which comprises a water inlet; steel pipe upright columns are arranged on two sides of the water inlet, and the tops of the steel pipe upright columns are connected through steel beams; a flexible protective net is hung on the steel beam, and a pattern steel plate is arranged below the flexible protective net. The utility model overcomes the problem that the slope support mode is difficult to drop the water inlet top platform equipment damage to high steep side slope rubble has reduced the tower water inlet potential safety hazard of high steep side slope ashore.
Description
Technical Field
The utility model relates to a protective structure at tower water inlet top of bank belongs to hydraulic engineering technical field among the hydraulic engineering.
Background
In hydro-power engineering, water intakes are one of the most important buildings of hydroelectric power plants, of which shore tower intakes are the most common. In the arrangement of a hydraulic hub, because of the limitation of terrain and geological conditions, the rear slope of a tower-type water inlet on a bank is high and steep, when a project is built, the support is mainly carried out on the slope in the forms of net hanging anchor spraying, anchor cables and active and passive protective nets at present, so that the integral stability of the slope and the falling of large stones can be prevented, but the phenomena of broken stones and falling blocks rolling off from the rear high and steep slope can happen occasionally, the damage to equipment on a platform at the top of the water inlet can be caused, and potential safety hazards exist.
For example, the protection structure for the water inlet of the front pool of the hydropower station disclosed in the chinese patent with the publication number CN205501958U mainly aims at protecting the structural safety of the water inlet, or integrally supporting the slope of the water inlet, and does not consider the protection of equipment at the top of the water inlet by falling of high slope crushed stones.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a protective structure at tower water inlet top of bank, this protective structure at tower water inlet top of bank have overcome the slope support mode and have been difficult to solve the problem that the high steep side slope rubble drops and causes water inlet top platform equipment to damage, have reduced tower water inlet potential safety hazard of high steep side slope disembarking.
the utility model discloses a following technical scheme can realize.
The utility model provides a protective structure at the top of a shore tower type water inlet, which comprises a water inlet; steel pipe upright columns are arranged on two sides of the water inlet, and the tops of the steel pipe upright columns are connected through steel beams; a flexible protective net is hung on the steel beam, and a pattern steel plate is arranged below the flexible protective net.
The steel pipe stand sets up 0.5 ~ 1.0m department outside the water inlet operating range.
The specification of the steel tube column is not less than phi 529x 8.
The height of the steel pipe upright column close to the mountain side is higher than that of the steel pipe upright column close to the reservoir side.
The included angles between the steel beam and the horizontal plane and between the steel plate with the patterns and the horizontal plane are 15-30 degrees.
The flexible protective net has two layers, and the meshes of the two layers of flexible protective nets are arranged in a staggered manner.
And the distance between the naturally drooped flexible protective net and the patterned steel plate is 20-30 cm.
The safe operation height between the patterned steel plate and the water inlet is 1.0-2.0 m.
The beneficial effects of the utility model reside in that: the problem of side slope support mode be difficult to drop to high steep side slope rubble and cause water inlet top platform equipment damage is overcome, tower water inlet potential safety hazard in high steep side slope ashore has been reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
In the figure: 1-steel tube upright posts, 2-water inlets, 3-steel beams, 4-flexible protective nets and 5-patterned steel plates.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1, the protection structure at the top of the shore tower type water inlet comprises a water inlet 2; the two sides of the water inlet 2 are both provided with steel pipe upright columns 1, and the tops of the steel pipe upright columns 1 are connected through steel beams 3; a flexible protective net 4 is hung on the steel beam 3, and a pattern steel plate 5 is arranged below the flexible protective net 4.
The steel pipe upright column 1 is arranged at a position 0.5-1.0 m outside the operation range of the water inlet 2.
The specification of the steel tube upright post 1 is not less than phi 529x8, and can be properly adjusted according to the scale of a water inlet.
The height of the steel pipe upright post 1 close to the mountain side is higher than that of the steel pipe upright post 1 close to the reservoir side.
The included angles of the steel beam 3 and the patterned steel plate 5 and the horizontal plane are all 15-30 degrees; after the broken stones are buffered by the flexible protective net 4, the broken stones fall on the patterned steel plate 5 and slide into the reservoir.
The flexible protective net 4 has two layers, and the meshes of the two layers of flexible protective nets 4 are arranged in a staggered manner and used for resisting the first impact of broken stones.
The distance between the flexible protective net 4 and the patterned steel plate 5 after the flexible protective net naturally droops is 20-30 cm, and the broken stone is prevented from being transmitted to the patterned steel plate 5 under the first impact load.
The safe operation height between the patterned steel plate 5 and the water inlet 2 is 1.0-2.0 m.
