Description
Technical field
The utility model relates to a kind of construction implement, especially a kind of segmenting slip casting pipe being applicable to reinforce for soft soil layer in shallow-depth-excavation tunnel construction.
Background technology
Shallow tunnel engineering construction is carried out at soft stratum especially soil layer, often because excavation construction causes Stratum Loss, there is country rock large deformation or cave in, jeopardize constructor and device security, and cause ground settlement excessive because of Stratum Loss, cause surrounding enviroment to damage, bring to the normal productive life of resident and have a strong impact on.For guaranteeing construction safety, reduce the impact of Construction on Environment, the normal grouting and reinforcing method formation that adopts carries out pre-reinforcement both at home and abroad at present.
In traditional grouting and reinforcing, slurries diffusion in the earth formation has randomness, dispersiveness, is difficult to realize control territory slip casting, and the waste of slurries is comparatively large, and, if the accident such as grouting pressure or the excessive easy soil building body deformability of grouting amount is excessive, generation earth heaving; If grouting pressure or grouting amount too small, do not reach again the effect of strengthening stratum, therefore cannot realize the uniform consolidation of formation.Formation carries out the effect that segmenting slip casting can have formation uniform consolidation.
At present, formation is carried out segmenting slip casting and is generally adopted the Grouting Pipe laying many different depths, different depth, different soil character are applied to different grouting pressures and carries out slip casting, but this method have injection speed slow, long in time limit, waste need be caused by Grouting Pipe more, cost is high, operation is many and the defects such as complexity, drastically influence the stable of construction period and surrounding enviroment, further, along with needing the increase problem of Grouting Consolidation scope more to highlight.
Utility model content
Technical problem: the purpose of this utility model overcomes the weak point of prior art, provide a kind of structure simple, be easy to operate, the easy to use segmenting slip casting pipe reinforced for soft soil layer.
Technical scheme: for achieving the above object, the segmenting slip casting pipe reinforced for soft soil layer of the present utility model, comprise the feed pipe for mortar be connected with pressure-adjustable slurry filling machine, feed pipe for mortar connects an inner Grouting Pipe through joint, inner Grouting Pipe top closure, bottom is connected with feed pipe for mortar, described inner Grouting Pipe is set with an outside Grouting Pipe, the top of inner Grouting Pipe is evenly arranged multiple inner injected hole, the both sides up and down of multiple inner injected hole are respectively equipped with two the grouting ring taps be fixed in inner Grouting Pipe, the external diameter of described two grouting ring taps leans on outside Grouting Pipe inwall, on the tube surfaces of described outside Grouting Pipe, interval has been evenly arranged multiple injected hole.
Described multiple inner injected hole is 2 ~ 4, arranges in the form of a ring.
Described grouting ring taps and outside Grouting Pipe inwall fit tightly.
Described inside Grouting Pipe is disposable Grouting Pipe, and Grouting Pipe can externally be free to slide by Grouting Pipe inwall.
Beneficial effect: owing to have employed technique scheme, the utility model can need to regulate pressure to realize the segmenting slip casting pipe that different soil character applies different grouting parameter according to soil layer, for soft layer and the more complex situations of strata division, different soil situation control grouting parameter is reached and accurately reinforces soft stratum, reach object that is quick, uniform consolidation stratum, increase the requirement of formation stability.Applied widely, be applicable to the soft stratum that all Engineerings need reinforcement.Have make simple, easy and simple to handle, with low cost, can repeat, the feature such as accurate segmentation location, economic benefit are high.
