Description
Technical field
The utility model is related to hydraulic engineering technical field, more particularly to a kind of mud-rock flow for cheuch area to protect knot
Structure.
Background technology
At present, it is arranged in the cheuch near major project, part cheuch only takes more on the ground of Construction of Hydropower Engineering branch
Ditch-water treatment measures, do not draw attention to Debris Flow.In recent years, Debris Flow becomes increasingly conspicuous, and some are yet to be built and are building
Engineering is to protect the safety of construction site, construction installation or slag field, and large-scale mud-rock flow protection must be carried out to part cheuch.
The material resource existed in order to be able to preferably solve the construction site being located in high mountain gorge is enriched, row leads difficult, influence
Great the problems such as, need to study it is a kind of can adapt to material resource side amount more, cheuch both sides massifs lithology preferably, exist and stop silt place
Mud-rock flow protection type, and be preferably combined with primitive groove water process measure, play investment reduction, shorten the purpose of duration.
Utility model content
To overcome existing cheuch place without mud-rock flow safeguard procedures, debris flow drainage leads the deficiencies such as difficulty, the utility model institute
The technical problem to be solved is：One kind is provided and can be suitably used for cheuch area protection mud-rock flow safeguard structure.
The utility model solves the technical scheme that its technical problem used：Mud-rock flow safeguard structure, including be arranged on
The comb dam of cheuch upstream and the blocking dam in cheuch downstream, are provided with the cheuch side massif between the comb dam and blocking dam
Scupper.
It is further to be provided with concrete apron at the lowest point after the comb Ba Ba.
It is further that the scupper includes relatively low subdrain hole and the position high-order scupper higher in position,
High-order scupper is connected with the middle part of subdrain hole.
It is further that the longitudinal section in the subdrain hole is downward-sloping step type.
It is further that the porch of the subdrain hole and high-order scupper is provided with steel grating door.
It is further that the barrel of the scupper uses concrete strengthening, and hole top is provided with the osculum for going deep into rock mass, low
Every section of vertical shaft lower section of position scupper is provided with one section of buffer well.
The beneficial effects of the utility model are：The structure type being combined using comb dam, blocking dam and scupper, twice
Dam body classification gear shield, instable slope clears up empty slag in time, and exit or entrance of a clitch downstream sets scupper, by ditch-water and the sandstone of flowing row
Walk, solid matter is blocked in ditch, it is effective to solve the problems such as material resource in cheuch is abundant, debris flow drainage is led difficulty, influences great.
Brief description of the drawings

Fig. 4 is the utility model scupper section structure schematic diagram.
Mark is 1- comb dam, 2- blocking dams, 3- scuppers, 4- steel gratings door, 5- osculums, 11- concrete shield in figure
It is smooth, 31- subdrains hole, 32- high position scuppers, 33- vertical shafts, 34- buffer wells, 35- transverse direction barrels.
Specific embodiment
The utility model is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, being horizontal layout form of the present utility model, including the comb dam 1 and ditch for being arranged on cheuch upstream
The blocking dam 2 in paddy downstream, scupper 3 is provided with the cheuch side massif between the comb dam 1 and blocking dam 2.The structure shape
Formula is generally located on the upstream of cheuch construction site, comb dam 1 both can excessively stream, the floating objects such as trees on the water surface can be stopped again,
Blocking dam 2 is used to intercept fixed sandstone, and ditch-water is then discharged from scupper 3, and when there is mud-rock flow, most sandstone can quilt
Intercept in the cheuch between blocking dam 2 and comb dam 1, timing is cleared up, ditch-water is then drained from scupper 3, do not interfered with
To the construction site in downstream.
As shown in Fig. 2 when ditch-water is flowed down from comb dam 1, can be impacted to dam bottom, the time one is possible to comb dam long
1 stability is impacted, so being provided with concrete apron 11 at the lowest point after the Ba Ba of the comb 1.
The scupper 3 includes relatively low subdrain hole 31 and the position high-order scupper 32 higher in position, high position row
Water hole 32 is connected with the middle part in subdrain hole 31.When there is mud-rock flow, the entrance in subdrain hole 31 is possible to can quilt
Mud-rock flow is blocked, and now ditch-water can flow away from high-order scupper 32, blocking dam 2 will not be covered because of blocking and enters construction site.
The longitudinal section in the subdrain hole 31 is downward-sloping step type, as shown in figure 3, including gently towards downstream
Inclined horizontal barrel 35 and vertical shaft straight down 33, the gradient of horizontal barrel 35 are smaller, can slow down the flow velocity of current, from
And the subdrain hole 31 of being brought into by current for avoiding silt excessive is drained, the blocking of scupper is caused, it is ensured that most of silt is all
Can rest in the cheuch before blocking dam 2.
Further, in order to the sandstone for preventing bulk enter into scupper 3, in the subdrain hole 31 and high-order draining
The porch in hole 32 is provided with steel grating door 4 and is protected, as shown in Figure 4.
Because scupper 3 is washed away by ditch-water for a long time, easily cause rockmass corrosion, cracking, or even collapse wait danger, in order to carry
The stability of scupper high 3, the barrel to scupper 3 is reinforced using concrete, and hole top is provided with the osculum for going deep into rock mass
5, the lower section of every section of vertical shaft 33 in subdrain hole 31 is provided with one section of buffer well 34, as shown in figure 4, concrete resistance to erosion, and energy
Support firm effect is played to barrel, is possible to occur seeping water in the rock mass on hole top drained, it is necessary to set osculum 5, kept away
Exempt to cause concrete to depart from rock mass.Can be produced when ditch-water is from the vertical shaft 33 in subdrain hole 31 into next section of horizontal barrel 35
Impact, so setting one section of buffer well 34 in the underface of vertical shaft 33 flows into row buffering to water, reduces the loss to barrel.
Traditional mud-rock flow protection is more to be intercepted only with blocking dam, and solid matter side's amount of blocking is less, and desilting bar
Part is poor, and in the case of many unfavorable factors such as material resource is abundant, place is more difficult, influence is great are faced, traditional is to keep off shield
Main safeguard procedures are difficult to meet and require.And the utility model is solved well in the form of based on being led with row, supplemented by gear shield
Debris Flow, and simple structure, the duration are fast, and using effect is good, with good practicality and application prospect.
