Description
Technical field
The present invention relates to engineering construction, more particularly to a kind of highway foundation or basic unit and building soft foundation grouting and reinforcing are mended
Strong method.
Background technology
Road in use, is acted on by traffic load and natural environment, and pavement performance is gradually reduced, and is occurred various
Damage, wherein many diseases are insufficient relevant with the unstable or intensity of basic unit or ground, such as crack, differential settlement, comes to nothing.
Foundation strength, reinforcement and strengthening soft foundation are improved to improving road pavement performance, is increased the service life most important.Opened using non-
Dig grouting reinforcing technology and repair foundation diseases, convenient and swift, quantities is small, and cost is low, avoids and fills out big digging greatly, to traffic impact
It is small, the bearing capacity of soft foundation and basic unit can be significantly improved, just progressively turns into the important means of road maintenance.
No-dig technique grouting and reinforcing Strengthening Technology as a kind of comprehensive professional technique, its repairing effect not only with injecting paste material
It is relevant, also influenceed by grouting process.Traditional grouting method uses a hard hollow tube, and slurries are under grouting pressure along slip casting
Pipe push downwards, injects in soft foundation from ttom of pipe.Slurries spread by itself mobility to surrounding, easily reunite together,
Spread uneven, blind effect is poor.Because slurries are concentrated, it is impossible to be uniformly distributed, slurries are assembled excessive area and easily caused
The too high protuberance of ground, the very few local magnitude deficiency of slurries.Slow, increase that slurries in Grouting Pipe port aggregation also result in slurry-outlet velocity
Grouting pressure.Existing grouting method entirety slip casting reinforcing effect is poor, it is impossible to meets actual requirement well, or even needs secondary injection
Slurry.
Therefore, a kind of novel slurry filling method is researched and developed, makes slurries diffusion uniform, accelerates slurry-outlet velocity, to improving slip casting
Technique, improving grouting reinforcing effect has Great significance.
The content of the invention
The purpose of the present invention is to overcome deficiency of the prior art, there is provided one kind is used for highway foundation or basic unit and building is soft
Weak grouting and consolidation on foundation reinforcement, slurries diffusion can be made uniform, accelerate injection speed, improve the slip casting side of grouting reinforcing repairing effect
Method.
In order to solve the above-mentioned technical problem, the present invention provides a kind of highway foundation or basic unit and building soft foundation slip casting adds

The mozzle that chute is connected；
(3) connecting tube is connected in the slip casting body upper end, then inserted slip casting body one end along injected hole, the other end
It is connected by connecting tube with grouting pump；
(4) grouting pump is opened, slurries flow into Grouting Pipe body, and are flowed downward along slip casting body, when slurries flow to Grouting Pipe
During body end, slurry diversion, mozzle is flowed into；
(5) mozzle is under slurry pressure effect, along guiding gutter slide downward, and in " ten " font to overhanging
Exhibition, makes nested type mozzle deploy step by step；
(6) slurry outlet that slurries are set from slip casting body and mozzle flows out respectively, slurries diffusion, until reaching advance
The grouting and reinforcing position of determination and scope；
(7) stop slip casting, extract Grouting Pipe.
The mozzle is formed for multistage nested semi-rigid flexible pipe, each stepped diversion pipe by mozzle buckle and
Mozzle neck nested encryptions step by step.
The end of the mozzle is connected with mozzle conical head, and slurry outlet is provided with the mozzle conical head.
Slurry outlet is offered in the side wall of the stepped diversion pipe.
The slip casting body card mutually fixed with mozzle buckle is provided with the inner wall at end of the arc structure of the guiding gutter
Button.
The slurry outlet being connected with the guiding gutter is offered on the slip casting body end side wall.
The slip casting body and the junction of the connecting tube are provided with rubber cushion.
The beneficial effects of the invention are as follows：Grouting serous fluid can be split into four strands of slurries by the inventive method in slip casting pipe end,
And flow out Grouting Pipe to different directions in " ten " font so that grout mixing is wider, is more evenly distributed on soft foundation
Interior, slurry-outlet velocity is fast, and grouting consolidation effect is good, can avoid secondary grouting.
