Description
Technical field
The utility model belongs to mud-rock flow and blocked facility technology field, is related to a kind of gully type, can resist larger solids
The mud-rock flow blocking dam of matter, more particularly to a kind of light-duty mud-rock flow arch blocking dam.
Background technology
Blocking dam is can to control or improve ditch bed part using a kind of relatively more extensive facility in debris flow control works
The erosion basis in location, prevent gully bed downcutting in alluvial area；A large amount of silts are intercepted more than dam site, thus it is possible to vary mudstone fluidity
Matter, reduce and let out scale under mud-rock flow；It can also widen ditch bed, grade elimination.Wherein, masonry gravity dam is a kind of main class
Type, masonry gravity dam are typically arranged using the linear pattern perpendicular to primary fluid flow line direction.In order to resist mud-rock flow to dam body
Caused active force, and meet the requirement such as structure monolithic stability and antiskid, antidumping by self gravitation.Should but actual
It is poor with the impact resistance of blocking of middle masonry gravity dam, easily produce failure by shear, dam body phenomenon of destroying by rush of water happens occasionally, so dam body
The general scale of construction is larger, and buried depth is big, and it is more to consume material.
Utility model content
The purpose of this utility model is to provide a kind of light-duty mud-rock flow arch simple in construction, safe and reliable, saving material
Blocking dam.
To achieve the above object, technical scheme is used by the utility model：A kind of light-duty mud-rock flow arch blocking dam,
Including multiple two arch springing foundations blocked the vertical coupling beam of arch and be arranged at raceway groove two sides, between two arch springing foundations, from upper past
Under be disposed with multiple main arch rings of blocking, have space between two neighboring main arch ring of blocking, the both ends of main arch ring of blocking difference
It is affixed with two arch springing foundations；Multiple vertical coupling beams of arch of blocking are arranged side by side, and affixed with main arch ring of blocking, two neighboring to block
There is gap between main arch ring, it is two neighboring to block main arch ring and the two neighboring vertical coupling beam of arch of blocking surrounds space.
The dam body of the utility model blocking dam is dome grating formula, first using domes, original mud-rock flow is vertical
Dam body impulsive force decomposes the compression in diagenesis main arch ring direction, and finally this compression is delivered in the Rock And Soil of raceway groove two sides, its
It is secondary, due to there is good mechanics effect, so making several grating type spaces, spilled water hole effect is served, can be carried out big
Flow drains off floodwaters, and mud-rock flow solid matter of blocking, and overcomes traditional stone masonry retaining wall and conducts oneself with dignity by large volume to resist mudstone
Impulsive force is flowed, the resistance to overturning, the anti-impulsive force of mud flow and shear behavior of mud-rock flow blocking dam can be improved, therefore, this is blocked
Dam has the advantages that not having to set overfall.The blocking dam have it is simple in construction, safe and reliable, save material, reduce cost etc.
Advantage.

Embodiment
Utility model is described further with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, the utility model blocking dam, including it is arranged at two arch springing foundations 3 of raceway groove two sides and more
The individual vertical coupling beam 2 of arch of blocking, between two arch springing foundations 3, it is horizontally disposed with successively there are multiple main arch rings 1 of blocking from top to bottom, block
Gear main arch ring 1 is arch, the direction of flow of the vault of main arch ring 1 of blocking towards mud-rock flow 5；It is two neighboring block main arch ring 1 it
Between have space, the both ends for main arch ring 1 of blocking are affixed with two arch springing foundations 3 respectively；Multiple vertical coupling beams 2 of arch of blocking are vertical side by side
Set, and it is affixed with main arch ring 1 of blocking, there are gap, the two neighboring He of main arch ring 1 of blocking between two neighboring main arch ring 1 of blocking
The two neighboring vertical coupling beam 2 of arch of blocking surrounds a space 10.
The construction process of the utility model blocking dam：
1）Excavate the basis by two ditch banks in raceway groove setting position, during excavation, can be used according to different geological conditions
Excavator or hand excavation, if having basement rock in ditch water front 4, it is excavated to middle weathering or weak weathered rockses face；If ditch
It is soil layer in water front 4, then is excavated to 2~3m depths；
Excavate bottom on trench floor to block the basis of main arch ring 1, digging is deep to raceway groove erosion line below 6, then placed
Bottom is blocked main arch ring steel reinforcement cage 8, is poured bottom and is blocked main arch ring steel reinforcement cage 8, pour bottom block main arch ring steel reinforcement cage 8 when,
What reserved main arch ring steel reinforcement cage 8 of blocking with bottom was connected, which block, encircles vertical coupling beam steel reinforcement cage 9, and reserves bottom and block main arch ring steel
The both ends of muscle cage 8；
2）Arch springing foundation steel reinforcement cage 7 is placed respectively in the basis of two ditch banks, by the lower end of arch springing foundation steel reinforcement cage 7 and in advance
The bottom stayed the both ends colligation of main arch ring steel reinforcement cage 8 of blocking is good, pour, and reserves and all is connected with pin reinforcement foundation cage 7 when pouring
Block and encircle vertical coupling beam steel reinforcement cage 9, adjacent two vertical coupling beam steel reinforcement cages 9 of arch of blocking are not attached to, as shown in Figure 3；
3）The good all vertical coupling beam steel reinforcement cages 9 of arch of blocking being connected with arch springing foundation steel reinforcement cage 7 of colligation, are poured, formation is blocked
Gear encircles vertical coupling beam 2, has gap between the two neighboring vertical coupling beam 2 of arch of blocking, when pouring, in each vertical coupling beam steel of arch of blocking
The main arch ring steel reinforcement cage 8 of blocking being connected with the vertical coupling beam steel reinforcement cage 9 of arch of blocking is reserved on muscle cage 9；
4）The good all main arch ring steel reinforcement cages 8 of blocking in addition to bottom blocks main arch ring steel reinforcement cage 8 of colligation, pour coagulation
Soil, main arch ring 1 of blocking is formed, has space between two neighboring main arch ring 1 of blocking, builds up light-duty mud-rock flow arch blocking dam.
Block main arch ring 1 vault towards the direction of flow of mud-rock flow 5, the arch springing at the both ends of main arch ring 1 of blocking is respectively deeply
Into the steady soil of raceway groove two sides, several vertical coupling beams 2 of arch of blocking mainly are connected the main arch ring of blocking of different height
1, form several spaces between the vertical coupling beam 2 of arch and main arch ring 1 of blocking blocking, it is ensured that when mud-rock flow 5 occurs, can block
Greater particle size stone solid matter, and the material such as small particle rubble or silt can be drained smoothly, not influence flood discharge.
The vertical dam body impulsive force of the utility model blocking dam mud-rock flow resolves into the compression along main arch ring direction, finally will
This compression is delivered in the Rock And Soil of raceway groove two sides, secondly as having good mechanics effect, so making several grids
Formula space, spilled water hole effect is served, big flow can be carried out and drained off floodwaters, mitigate blocking dam impulsive force, and mud-rock flow solid of blocking
Material, the problem of traditional stone masonry retaining wall conducts oneself with dignity to resist the impulsive force of mud flow by large volume is overcome, improves mudstone
Resistance to overturning, the anti-impulsive force of mud flow and the shear behavior of blocking dam are flowed, therefore, the blocking dam, which has, not to be had to set overfall
The advantages that.The blocking dam have the advantages that it is simple in construction, safe and reliable, save material, reduce cost.
