Abstract
The utility model discloses a kind of seepage control of dam processing system, including dam body, drilling is set on dam body, the mud mixed up is poured into from drilling, mud is mutually communicated in the bottom of drilling, so that dam body bottom is all in the milk, improves grouting quantity, and then improve anti-seepage effect.Mud can cause impact force to the inner wall of drilling in filling process, and sleeve can reduce the impact force, avoid the inner wall of drilling from being damaged, and the flow velocity of protrusion mud when can slow down grouting on sleeve lining, further cut down impact force.In addition, during grouting, it is dilute after mud is first dense, it is therefore an objective to tiny and distant fracture void elder generation packing, then to increase concentration again, be allowed to fill larger gap crack.Mud fills drilling, then by each borehole sealing, can thus realize watertight grouting.
Description
Technical field
The utility model belongs to water conservancy projects technical field, and in particular to a kind of seepage control of dam processing system.
Background technology
At the slope foot of dam downstream, i.e., leakage is often had at the dam foundation, water level is higher, and leakage is more serious, this indicates that dam side
It is damaged at angle, leakage is produced, the repair mode of the dam foundation is typically manually repaired in the prior art, the mode manually repaired
Danger coefficient is high, and heavy workload, and labor intensity is big, and work efficiency is low.
Utility model content
The technical problems to be solved in the utility model is in view of the foregoing drawbacks, there is provided a kind of seepage control of dam processing system, should
Seepage control of dam processing system is easy to the reparation of leakage, good seepage-proof property.
In order to solve the above technical problems, the utility model includes dam body, the upper surface of the dam body is interval with multiple energy
The drilling connected with dam body bottom, is connected between each foot of hole by cross through hole, sleeve is equipped with the inner wall respectively to drill,
The outer surface of the sleeve is equipped with impervious barrier, and the inner surface of sleeve is evenly equipped with multiple protrusions.
Each sleeve includes concrete layer, and the middle part of concrete layer is equipped with reinforcing bar.
The depth of each sleeve is all higher than 2/3rds of drilling depth.
The upper end of each sleeve is equipped with clamping portion, and the diameter in each clamping portion is all higher than the diameter of each drilling.
Each sleeve diameter is respectively less than a diameter for drilling.
The drilling is set in a row along the length direction of dam body, and the drilling is provided with two rows.
Two row hole drilling is staggered.
The center of circle per row hole drilling is on same straight line.
The utility model has the following advantages compared with prior art：The mud mixed up is poured into from drilling, mud is boring
The bottom in hole is mutually communicated, so that dam body bottom is all in the milk, improves grouting quantity, and then improve anti-seepage effect.Filling process
Middle mud can cause impact force to the inner wall of drilling, and sleeve can reduce the impact force, avoid the inner wall of drilling from being damaged, and
The flow velocity of mud, further cuts down impact force when protrusion on sleeve lining can slow down grouting.In addition, during grouting, mud is first
It is dilute after dense, it is therefore an objective to tiny and distant fracture void elder generation packing, then to increase concentration again, be allowed to fill larger gap
Crack.Mud fills drilling, then by each borehole sealing, can thus realize watertight grouting.
In conclusion the utility model is easy to the reparation of leakage, good seepage-proof property.
Brief description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is sectional view along A-A in Fig. 1；
The top view of Fig. 3 Fig. 1；
Fig. 4 is the structure diagram of sleeve.
Embodiment
Seepage control of dam processing system as Figure 1-Figure 4, including dam body 1, the upper surface of dam body 1 are interval with multiple energy
The drilling 2 connected with dam body bottom, drilling 2 are set in a row along the length direction of dam body 1, and drilling 2 is provided with two rows.Two row hole drillings
2 are staggered, and this setup can destroy the support strength of dam body to avoid drilling 2.The center of circle per row hole drilling 2 is same
On bar straight line.As shown in Fig. 2, respectively being connected between 2 bottoms of drilling by cross through hole 3, the grouting area of bottom, Jin Erzeng are improved
Big anti-seepage effect.Sleeve 4 is equipped with the inner wall of each drilling 2, the outer surface of sleeve 4 is equipped with impervious barrier 43, avoids leakage from causing
Dam body support strength reduces.The inner surface of sleeve 4 is evenly equipped with multiple raised 44.Each sleeve 4 includes concrete in the present embodiment
Layer 41, the middle part of concrete layer 41 is equipped with reinforcing bar 42, and the sleeve 4 of the structure can improve anti-impact force.The depth of each sleeve 4 is equal
More than 2/3rds of 2 depth of drilling, increase the protection domain of sleeve 4.As shown in Figure 3 and Figure 4, the upper end of each sleeve 4 is equal
Clamping portion 40 is equipped with, the diameter in each clamping portion 40 is all higher than the diameter of each drilling 2, and clamping portion 40 is contacted with the outer of drilling 2,
Easy to the installation of sleeve 4, clamping portion 40 can realize the positioning of sleeve 4.Each 4 diameter of sleeve is respectively less than a diameter for drilling 2, just
In sleeve 4 is inserted into drilling 2 in.
The slurry of grouting in the present embodiment selects silty clay to be made with weight silt loam and cement, and clay content is
30%, silty content is 40%, cement content 20%.Mud density is controlled in 1.5-1.7g/cm3, concentration of hydraulic mixture: slime water
Soil is than control 1: 0.5-1: 1.4.The mud mixed up is poured into from drilling 2, mud is mutually communicated in the bottom of drilling 2, so that
Dam body bottom is all in the milk, improve grouting quantity, and then improve anti-seepage effect.Mud can be to the inner wall of drilling 2 in filling process
Impact force is caused, and sleeve 4 can reduce the impact force, avoid the inner wall of drilling 2 from being damaged, and the protrusion on 4 inner wall of sleeve
