Description
Technical field
This utility model relates to a kind of debris flow technology, particularly relates to a kind of full lined debris flow drainage groove based on ring flat-plate energy dissipating, deceleration.
Background technology
Mud-rock flow is one of common geologic hazard type in mountain area, relatively conventional in China, and its outburst is suddenly, movement velocity is fast, destructive power is strong, and infrastructure construction and people's lives and properties often cause serious harm and threat. Mud-stone flow disaster is administered and is mainly included Geotechnical Engineering measure, ecological engineering measure and control measures three major types, wherein, one of major project that drainage groove is prevented and treated as mud-rock flow Geotechnical Engineering, play an important role in debris flow.
In debris flow control works, drainage groove has conveying mud-rock flow and guide functions. Owing to the silt content of mud-rock flow is high and containing boulder, movement velocity is fast, easily drainage groove is impacted ablation destruction, causing bottom drainage groove and side wall is impaired, the row having a strong impact on drainage groove leads performance and service life; In the drainage groove that longitudinal river slope is bigger during flowing, mud-rock flow speed and energy are all very big, and infrastructure (such as bridge pier etc.) on the way is also had very big impact failure power.
Utility model content
The purpose of this utility model be aiming at present because mud-rock flow speed is fast, energy is high drainage groove has bigger ablation destruction and infrastructure on the way has the situation of great impact destructive power, a kind of full lined debris flow drainage groove of ring flat-plate energy dissipation type that can reduce debris flow velocity, dissipation mud-rock flow energy is provided, reduces mud-rock flow to the ablation destruction degree of drainage groove and Impact Fracture Resistance.
For achieving the above object, the technical solution of the utility model is:
The utility model proposes a kind of full lined debris flow drainage groove of ring flat-plate energy dissipation type, the drainage groove base plate built including full lining and the drainage groove side wall of both sides, drainage groove is provided with some ring flat-plates (i.e. multistage ring flat-plate) being distributed at a certain distance, described ring flat-plate is laid along drainage groove cross section (be namely perpendicular to mud-rock flow flow to cross section), is all connected with drainage groove side wall and base plate, top end opening, centre have current by pass (top end opening of ring flat-plate connects) with current by pass, and ring flat-plate upstream side is provided with arc drain and pastes angle.On ring flat-plate, current by pass edge be provided with wash-prime coat.
By to mud-rock flow motion subtree in drainage groove, mud-rock flow flow velocity in drainage groove is very big, especially when drainage groove longitudinal river slope is bigger, drainage groove can be produced very big impulsive force and ablation destruction ability by mud-rock flow in motor process, has a strong impact on flow conductivity and the service life of drainage groove. The problem such as big for mud-rock flow flow velocity in drainage groove motor process, impact failure power is strong, the utility model proposes and multistage ring flat-plate is set in drainage groove, mud-rock flow is made to be undergone mutation by the flow section of drainage groove, cause that debris flow velocity is along flowing to generation acute variation, affect the stability of its flowing, mud-rock flow also can be made to produce whirlpool roll, produce shearing friction therein and collide the effect reducing flow velocity and energy loss. Adopt multistage ring flat-plate that mud-rock flow repeatedly sudden contraction and sudden expansion can be made to increase effect of energy dissipation.
At ring-plane structure design aspect, arranging arc drain patch angle at ring flat-plate upstream side, wash away reducing the mud-rock flow abrasion to ring flat-plate Yu drainage groove junction, arc drain patch angle and drainage groove side wall, base plate and ring flat-plate connect into entirety the mode such as anchoring or weld; In order to increase the wearability at arc drain patch angle, arc drain patch angle can adopt steel. For reaching drainage, it is possible to construction time on ring flat-plate, current by pass edge do corner angle sphering process. Consider that ring flat-plate is for a long time by the direct impact of high speed mud-rock flow; and on ring flat-plate, current by pass edge weakness relatively be subject to impact ablation destruction; for ensureing resistance to abrasion and the resistance to impact at collar extension place (namely on ring flat-plate, current by pass edge); therefore on ring flat-plate, current by pass edge increase certain thickness wash-prime coat protect, wash-prime coat material can adopt steel.
The design of ring flat-plate relevant parameter is as follows: ring flat-plate thickness and current by pass diameter are with the design width of drainage groove for foundation; If ring flat-plate is too thin, impact resistance will be too poor, is unfavorable for the stability of ring flat-plate self, if ring flat-plate is too thick, considers to waste very much again from economic aspect, so, ring flat-plate thickness a is generally 0.5-0.8m. Current by pass conveniently of circular shape, current by pass diameter D is generally 0.6 times of drainage groove width B. Ring flat-plate height, with drainage groove projected depth for foundation, is typically designed as ring flat-plate height h equal to drainage groove depth H. Clear spacing between ring flat-plate and ring flat-plate is with drainage groove design length and width for foundation, if the clear spacing between ring flat-plate is excessive, when mud-rock flow reaches next stage ring flat-plate by one-level ring flat-plate, to the energy before the space recovery that mud-rock flow is enough and flow velocity, not only can not reach the effect of energy dissipating, deceleration, also can cause the waste in engineering; If the clear spacing between ring flat-plate is too small so that debris flow velocity reduction too substantially easily causes accumulation of mud, reduces the guide functions of drainage groove, so the clear spacing L between ring flat-plate is generally 3-4 times of drainage groove width B. The top end opening edge of ring flat-plate is generally the 1/10 of drainage groove width B to the distance b of side wall.
Ring flat-plate is connected by dowel is fixing with drainage groove side wall and base plate, to ensure the globality of ring flat-plate and drainage groove. Embedding dowel length is side wall thicknesses A the 3/4 of side wall, the corresponding dowel length embedding ring flat-plate is current by pass 3/4 from side wall beeline x; The dowel length embedding base plate is 0.6m, and the corresponding dowel length embedding ring flat-plate is current by pass 3/4 from base plate beeline y.
The ratio of drainage groove width B and drainage groove depth H is 1-1.2, it is adaptable to longitudinal gradient ratio drops 150 ��-300 ��. For coordinating the use of this utility model full lined debris flow drainage groove of ring flat-plate energy dissipation type, it is possible to adopt in drainage groove upstream mud-rock flow to block engineering measure, control the largest block stone particle diameter entering drainage groove less than 1m.
Compared with prior art, the beneficial effects of the utility model are: utilize the multistage ring flat-plate in drainage groove, mud-rock flow is made to have repeatedly sudden contraction sudden expansion phenomenon in motor process, mud-rock flow is made to be undergone mutation by the flow section of drainage groove, cause that debris flow velocity is along flowing to generation acute variation, affect the stability of its flowing, thus reaching the effect of deceleration, energy dissipating, the mud-rock flow ablation destruction degree to drainage groove can be greatly reduced, extend the safe service life of drainage groove, reduce the threat to infrastructure on the way (such as bridge pier) impact failure.
