Description
Technical field
The present invention relates to dam spillway strengthening construction fields, and one kind of waterproofing reinforcement is specifically carried out using slurry
The construction method of dam spillway ruggedized construction.
Background technology
Spillway is the flood protection device and discharge structure of the water constructions object such as reservoir, builds in the side of dam more, and overflow flood
Road generally infrequently works, but the important building in reservoir hinge.Spillway is as a large trough, for leading planning library off
Hold the flood that cannot be accommodated, when water level is more than margin of safety in reservoir, water is just downstream flowed out from spillway, prevents dam
It is destroyed.So spillway is self-evident to the importance of dam.However dam spillway is directly exposed among air,
The influence of natural environment is undergo, basis is susceptible to more typical seepage flow erosion attack.This seepage flow erosion attack is to big
The harm of dam spillway is mainly manifested in：Basic earth particle be lost in, formed cavity, and and then spillway bottom plate is caused to collapse,
The normal use of dam spillway is influenced, reduces the service life of dam spillway.Therefore, dam spillway is reinforced not
Only it is the important guarantee of the strength and stability of dam spillway, while can is that the service life creation for extending dam spillway has
Sharp condition.
Existing dam spillway waterproofing reinforcement measure, which mainly has, is laid with compound water-proof or composite geo-membrane, whitewashing anchoring
Reinforcement technique, Soil-nailed technology and slurry injection technique etc..Composite geo-membrane is combined not with geotextile and geomembrane
Seepy material, selected material are high molecular material, can be used in unconventiona temperature environment, but compound water-proof or multiple
Closing the seam of geotechnological mould often becomes penetrating passage；Whitewashing anchoring reinforcement technique is by anchor pole, rock mass, bar-mat reinforcement and concrete surface
Layer works together to improve the structural strength of slope ground and resistance to deformation rigidity, reduces Rock And Soil lateral deformation, but it is this plus
Gu technology is higher with design requirement to controlling.Eum-Orthic Anthrosols are that certain length and the soil nailing of distribution density are placed in the soil body
Body, and native collective effect, to make up the deficiency of soil body self-strength.Soil body overall stiffness is not only increased, and compensates for soil
The low weakness of the tension and shearing strength of body, significantly improves overall stability, but soil nailing body in the side slope of dam both sides not
It can be distributed well.It is existing most efficient method to carry out dam waterproofing reinforcement using slurry injection technique, it is will be certain
In curable slurries injection Rock soil Foundation crack or hole, by replacing, filling, the modes such as squeezing and reinforced.Slip casting
Slurries include chemical grout, cement grout, mixed serum.In these types of slurries, high polymer slurry is anti-due to its generation chemistry
Should after can rapid expanding and curing, and its dilatancy is high and preferentially elected.
Therefore, in order to which slurry injection technique is allowed further to be developed in the reinforcing of dam spillway, we compel to be essential
Research and develop new grouting device, come push slurry injection technique dam spillway reinforcing in extensive use, improve construction efficiency with
And reduce construction cost.
