Description
Technical field
The utility model relates to geological disaster calamity technical field, specifically a kind of telescopic mud-rock flow blocking dam.
Background technique
Mud-rock flow is easily formed due to the excitation of the water sources such as heavy rain, ice dissolution, on mountain area cheuch or mountainous region slope surface.It contains
A large amount of silt stones are a kind of serious geological disasters for soil, water, the gas mixed flow between sediment laden flow and landslide.Mud
The solid matter that the generation of rock glacier, especially mud-rock flow carry has extremely strong destructive power, this gives the security of the lives and property structure of people
At seriously threatening.Control measure for the extent of injury for effectively avoiding and reducing mud-rock flow, mud-rock flow is particularly important.
Mud-rock flow block engineering be disaster prevention basic measure, solid matter and rain to mud-rock flow of blocking
Big vast runoff weakens and lets out total amount and energy under mud-rock flow, reduces mud-rock flow washing away, hit and deposit etc. and endanger to Lower Reaches
Evil.Engineering of blocking includes blocking quarrel dam, storage silt field, retaining engineering, cutting four class of big vast engineering.Preceding three classes, which rise, blocks quarrel, viscous flow, Gu Po work
With the solid matter for controlling mud-rock flow supplies, and the effect for cutting big vast engineering is control rain flood runoff, and final purpose is weakening mudstone
Stream.Traditional mud-rock flow blocking dam generallys use single material and technique, can substantially be divided into three classes: first kind concrete pours
Type is built, dam body all uses concreting；Second class is stone masonry masonry type, and dam body all uses stone masonry to build；Third
Class is armored concrete mixed type, and dam body all uses armored concrete pouring structure.Traditional three classes blocking dam has one
Determine defect: for concreting type, on the one hand block stone impact capacity and Abrasion properties are not good enough in its anti-mud-rock flow；Another party
For face mud-rock flow blocking dam common buildings in mud-rock flow channel, communications and transportation is inconvenient or even obstructed, and concrete is transported into outside ditch
Construction site increases building cost and difficulty.For stone masonry masonry type, advantage is to gather materials on the spot (in general mountain
Have block stone) cost is reduced, but easily appearance dislocation drawknot is not in place in the construction process, the not full or stone that is in the milk is strong for stone masonry
Phenomena such as degree does not reach requirement, will affect dam body general safety performance.For armored concrete mixed type, largely
It can effectively solve the problem that the problem of anti-block impact force of traditional blocking dam destroys, but transport difficult, cost cost are at multiplication
Add, and construction work amount is huge, thus is unable to get large-scale promotion build.The above blocking dam structure has common feature: knot
Structure is huge, and is fixed structure, this brings greatly not to dredging, Renovation after the build engineering of mud-rock flow blocking dam, calamity
Just.Therefore, those skilled in the art provide a kind of telescopic mud-rock flow blocking dam, to solve to propose in above-mentioned background technique
The problem of.
