Description
Technical field
Blocked engineering technology the present invention relates to a kind of mud-rock flow, especially a kind of especially big high-order mud-rock flow Self-resetting power consumption is blocked
Structure and its implementation are kept off, belongs to hazards control security technology area, an especially big high position in high steep mountain area is widely used in
The preventing and treating of mud-rock flow.
Background technology
At present, the especially big high-order mud-rock flow structure type of more main flow in engineering of blocking is gravity dam, crib dam, stake woods
Dam, stake trammel etc., wherein stake woods and stake trammel have the advantage that boulder impact was divided and ruled and resisted to water stone concurrently, in Gansu Zhouqu County three
Succeeded in the especially big Controlling Debris Flow engineerings such as eye Yu Gou, Luo Jia valley ditch, the peaceful literary family's ditch in Sichuan, the cold wooden ditch of Baoxing application.
Because the impulsive force of boulder in especially big high-order mud-rock flow is huge, especially big high-order mud-rock flow is blocked structure in engineering
Area of section, which is generally required, is designed to higher value, and links structure and thicker raft foundation often through setting up, and forms it into entirety
Rigidity very strong fabricated structure, this fully meets Controlling Debris Flow design requirement on mechanics.But if long-term multiple
By boulder " very stiff and demanding " power impact, structural material must cause irreversible damage accumulation and Progressive failure, add
Maintenance difficulties and cost.
Therefore in the urgent need to study it is a kind of can water stone divide and rule, resist the impact of boulder, passive energy dissipation can be considered again
New structure, improves the energy dissipation capacity of structure, reduces structure stress mutation and damage caused by instantaneous collision.
Especially big high-order debris flow has important social effect and economic value.The high-order mud-rock flow in China western mountainous areas
Ditch is more developed, if structure of blocking can not persistently resist boulder in mud-rock flow and impact for a long time, will easily form a large-scale high position
High speed mud-rock flow, destroy by rush of water downstream house, clog downstream river course, endangers huge.In addition, having broken out high-order mud-rock flow for one
Raceway groove, then need to put into engineering progress Emergency management immediately, prevent the further sociability of mud-rock flow from breaking out.
The content of the invention
The above mentioned problem that the purpose of the present invention exists aiming at prior art, by setting separated pile trammel and setting up
Earthquake isolating equipment and prestress anchorage cable, propose that a kind of new Self-resetting power consumption is blocked structure, so as to increase the power consumption of pile body and anti-
Jolt capacity.
The purpose of the present invention and solve its technical problem and can be achieved through the following technical solutions.
Blocked structure according to especially big high-order mud-rock flow Self-resetting power consumption proposed by the present invention, including：Two placing of reinforcement concrete
Stake, linking beam, mat foundation, prestress anchorage cable, damping material.First row armored concrete is separated pile structure, including two
Part：Front end arc pile body and afterbody rectangular pile body, the rectangular cross-section of second row reinforced concrete pile, mat foundation are also reinforcing bar
Concrete structure.Linking beam is divided into 4 kinds according to position：First continuous beam (3-1), the second continuous beam (3-2), the 3rd
Connected between continuous beam (3-3), the 4th continuous beam (3-4), first row rectangular pile body with the first linking beam (3-1)；First row square
Connected between shape pile body and massif with the second linking beam (3-2), the second linking beam (3-2) needs build-in to 1.5m in massif in addition；
First campshed rectangular pile body is connected with second row rectangular pile by triplex operating beam (3-3)；With between second row rectangular pile body
Four linking beams (3-4) are connected.
First row arc pile body, first row rectangular pile body and second row rectangular pile body all with mat foundation one-piece casting；The
One row's arc pile body is connected with mat foundation by multiple rows of vertical non-bonding prestress tendon insertion；First row arc pile body and square
Separated between shape pile body, and fill anticorrosion rubber damping material.
The detached section width of arc pile body and rectangular pile body in first row separated pile structure and highly consistent, stake is wide
2~3m.The horizontal length of arc pile body, i.e. detached section to the horizontal range of arc apex are 0.5~1.0m.Rectangular pile body
Horizontal length is 2~3m.
Multiple tracks evagination collar tie beam is set on the outside of the arc of arc pile body, and collar tie beam section is in circular arc, the adjacent turn of multiple tracks collar tie beam
Distance between girders distance about 2~4m, casting concrete beam or anchored by prefabricated arc girder steel can be formed at the scene.
Multiple rows of vertical non-bonding prestress tendon in arc pile body is mounted in inside concrete mat foundation.Anchor cable top
Anchored in arc pile body surface with anchor bolt, and protect anchor head with anchor lid outside.
Multiple rows of vertical non-bonding prestress tendon arrangement in arc pile body is linear pattern, or is arranged as arc, with
The outer arcuate shape of arc pile body is consistent.
Arc pile body and rectangular pile body fill damping material or EPS or other composite damping material, and can increase many
Group spring.Distance between arc pile body and rectangular pile body is 50mm.
Beneficial effect
Implement the method for the structure, it is characterised in that comprise the following steps：
First step：Unwrapping wire is measured in raceway groove bend or closing in section, mat foundation, the position of stake is determined；Second step：Apply
Work armored concrete mat foundation；Projected depth is excavated to, template is laid, steel reinforcement cage is put, raft foundation is poured into a mould；

Native stake；Wherein, directly reserve damping in first row front end arc pile body and rectangular pile body and fill seam, and in first row front end arc
Pile body internal reservation anchor cable passage, and Inner bolt head has been buried, anchor head is connected with anchor cable；
Four steps：Construction reinforced bar concrete horizontal links girder construction, and template, backer side insertion section level are laid in assembling reinforcement
The pore-creating of linking beam elder generation, places into steel reinforcement cage, casting concrete；
5th step, after after concrete strength enhancing, stretch-draw anchor forms prestressing force.
The especially big high-order mud-rock flow Self-resetting power consumption of the present invention is blocked structure, is had the following effects that：
(1) structure of blocking play water stone divide and rule, resist boulder effect on the basis of, the power consumption for further increasing structure subtracts
Shake ability, improve the service life of structure.The structure that will block flood control anti-impact standard brought up to 50 years chances from 20 years chances, tied
The service life of structure even can extend to 60 years；
(2) when structure of blocking is conjugated by megalith multiple impact, jack and multiple rows of vertical prestressing without bondn can be passed through
Anchor cable reaches the effect of reset, adds the anticollision reset capability of structure so that deformation can be with complete in the range of 20~50cm
All reset.
(3) the positive multiple tracks evagination collar tie beam of structure of blocking can have cusp slabbing action to megalith so that megalith is more broken, so that
The scattered Impact energy to agent structure.
(4) program is administered clear, it is workable；
(5) raceway groove for being used to occur high-order mud-rock flow is administered, it is therefore prevented that further sociability outburst mud-rock flow, is alleviated
Downstream place is destroyed.
In summary, the present invention technically has a significant progress, and with obvious good effect, really for it is one novel, progressive,
Practical technical method.
