Technical Field
The utility model belongs to the technical field of side slope and piece flow prevention and control, especially, relate to a piece flow protector suitable for severe area of landslide calamity.
Background
Debris flow is a high risk geological hazard in high mountain canyon regions worldwide, and high speed remote landslide debris flow is known for its ultra-high kinetic energy and ultra-long range of motion. Due to the high kinetic energy and the high fluidity of the debris flow, buildings (roads, houses, bridges and the like) and human activities (running vehicles, passing people and the like) in the movement range of the debris flow are often seriously damaged, and the large-scale debris flow directly causes the river to be blocked to form a barrage dam, so that the life and property safety of people is seriously threatened.
It is difficult to accurately predict the occurrence of debris flow, limited by the current state of the art of monitoring and uncertainty in the occurrence of debris flow. In order to cope with debris flow impact disasters, a protective structure is arranged in front of an area or a building to be protected, so that the disaster-causing range of landslide debris flow can be reduced, and the disaster-causing intensity can be weakened.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model lies in providing a protection barricade device of piece stream can adjust the height and the slope of barricade according to the disaster situation size, deals with the disaster situation more in a flexible way.
The utility model discloses a realize like this:
a debris flow guard suitable for use in severe landslide hazard areas comprising: the anchor rod is arranged in a slope area where debris flow can occur, a steel reinforcement framework is embedded in the area limited by the anchor rod, and a retaining wall foundation is cast in situ; building a retaining wall above the retaining wall foundation;
one side of the retaining wall facing the fragment flow is an arc surface, and the arc surface is in the shape of an arc with a central angle of 60 degrees and a radian of 1.04rad and is used for changing the movement speed of the fragment flow while blocking the high-energy fragment flow.
Further, hydraulic support structures are arranged on a flat top above the retaining wall at intervals, and each hydraulic support structure is provided with a blocking and protecting steel plate for blocking the flow of the scraps; every hydraulic support structure connects the pump station workstation in a distance, adjusts through the power supply that the pump station provided the opening and shutting size of hydraulic support structure's fender steel sheet.
Further, the model of the hydraulic support structure is JS860.
Further, the certain distance is 3-5m.
Further, the retaining wall is made of C40 concrete.
The utility model has the advantages that: can set up lower slope barricade according to actual conditions, reduce barricade height and slope, reduce the concrete use cost, use JS860 hydraulic structure to keep off, can keep off the opening and shutting size of protecting the steel sheet according to disaster size regulation, can block large-scale stone landing in a flexible way, deal with the disaster more in a flexible way.

The present invention will be further described with reference to the following examples and drawings.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic perspective view of the hydraulic support of the present invention.
Fig. 3 is a schematic diagram of a first state of the hydraulic support structure of the present invention.
Fig. 4 is a schematic diagram of a second state of the hydraulic support structure of the present invention.
Detailed Description
As shown in fig. 1 to 4, a debris flow guard device for a severe landslide disaster area includes: the anchor rod 5 is arranged in a slope area where debris flow can occur, a steel reinforcement framework is pre-embedded in the area limited by the anchor rod 5, and a retaining wall foundation 4 is cast in situ; and (3) building a retaining wall 1 (adopting C40 concrete) above the retaining wall 4 foundation.
One side of the retaining wall 1 facing the fragment flow is an arc surface, and the arc surface is in the shape of an arc with a central angle of 60 degrees and a radian of 1.04rad and is used for changing the movement speed of the fragment flow while blocking the high-energy fragment flow.
JS860 hydraulic support structures 2 are arranged on the flat top above the retaining wall 1 every 3-5m, each JS860 hydraulic support structure is provided with a blocking steel plate 21 for blocking debris flow, and each blocking steel plate 21 comprises a supporting top plate 211 and a side baffle 212; and each JS860 hydraulic support structure is connected with a remote pump station work station, and the opening and closing size of the JS860 hydraulic support structure 2 blocking and protecting steel plate 21 is adjusted through a power source provided by the pump station.
The JS860 hydraulic support structure 2 finishes lifting and descending of a hydraulic support by using high-pressure emulsion supplied by a pump station, and the pump station is arranged at a remote work station for control.
When the JS860 hydraulic support structure 2 needs to rise, high-pressure emulsion enters a piston cavity of the upright post, the other cavity returns liquid to push the piston to rise, and the opening and closing angle of the blocking and protecting steel plate 21 is increased; when the column needs to be lowered, high-pressure liquid enters a piston rod cavity of the column, and the other cavity returns liquid to force the piston rod to descend, so that the opening and closing angle of the blocking and protecting steel plate 21 is reduced, and the hydraulic support structure 2 is folded.
