Abstract
The invention discloses a roadbed subsidence grouting treatment structure and a construction method thereof. The roadbed subsidence grouting treatment structure comprises a plurality of rows of grouting pipe groups which are arranged on both sides of a central division strip of a roadbed and inserted at the interior of the roadbed horizontally from the outer side of the roadbed, wherein each row of grouting pipe groups comprise a plurality of grouting pipes; a plurality of grouting pipes in the same row are exposed at one end of the outer side of the roadbed and are communicated with one side of a same connecting pipe; the other side of the connecting pipe is communicated with a grouting main pipe; and drainage sewers in the same direction as the grouting pipes are arranged between two adjacent rows of grouting pipe groups. The grouting effect of a plurality of grouting pipes can be ensured, and accumulated water in the roadbed is drained in time; and moreover, the construction technology is simple, and the manufacturing cost is low.
Description
Technical field
The present invention relates to a kind of roadbed settlement slip casting punishment structure and job practices.
Background technology
Roadbed is the important structure facility of highway, also is one of important content of highway maintenance.Engineering practice shows that grouting strengthening method is one of effective ways of punishment subgrade settlement disease.Yet there are following defective in traditional roadbed settlement slip casting punishment structure and job practices: at first, when squeezing into a plurality of Grouting Pipe in the roadbed, can't carry out slip casting to a plurality of Grouting Pipe simultaneously, therefore the grouting pressure of each Grouting Pipe, slip casting duration etc. all can't guarantee identical, can cause each Grouting Pipe slip casting effect difference thus, problem such as the roadbed settlement lifting is inhomogeneous.Secondly, conventional construction method does not arrange sewer after slip casting is finished, and makes that the water in the roadbed can not in time be discharged behind the precipitation, and oozing under the precipitation can softening roadbed, influence the stable of roadbed and causes roadbed sagging.In this case, demand is a kind of urgently can make all identical job practicess of conditions such as the slip castings simultaneously of a plurality of Grouting Pipe and grouting pressure, and can guarantee the structure that the water in the roadbed can in time be discharged after slip casting simultaneously.
Summary of the invention
The present invention is intended to overcome the deficiencies in the prior art, and a kind of structure and job practices of roadbed settlement slip casting punishment is provided.
In order to achieve the above object, technical scheme provided by the invention is:
Described roadbed settlement slip casting punishment structure comprises some row's Grouting Pipe groups of being located at both sides, roadbed median strip and inserting roadbed from roadbed outside level, every row's Grouting Pipe group comprises some Grouting Pipe, the end that some Grouting Pipe of same row are exposed at the roadbed outside is communicated with same tube connector one side, and described tube connector opposite side is communicated with the slip casting house steward; Be provided with in the described roadbed and Grouting Pipe draining sewer in the same way.
Wherein, be filled with building stones in the described draining sewer.Described draining sewer tilts to the roadbed outer rim from the median strip.The slope of described draining sewer 〉=2% is preferably 10%.Described Grouting Pipe is slip casting spray of molten steel pipe; Described slip casting house steward and tube connector are steel pipe.Described every row's Grouting Pipe group comprises four Grouting Pipe.
The job practices of above-mentioned roadbed settlement slip casting punishment structure comprises the steps:
(1) set up scaffolding platform in the roadbed outer rim of both sides, median strip, adopt down-the-hole to beat into some row's Grouting Pipe groups, every row's Grouting Pipe group is made up of some Grouting Pipe; When breaking pipe, earlier Grouting Pipe is cut into 1.5～2.0m, one joint, after squeezing into a joint, next joint and a joint of having squeezed into is welded together, and then continue to squeeze into, make final section Grouting Pipe one end be exposed to the roadbed outside, the length of exposing is about 20cm;
(2) same row's some Grouting Pipe are exposed at an end and same tube connector welding in the roadbed outside, again tube connector and slip casting house steward are welded; Concrete, be earlier in the tube connector one side hole corresponding with some Grouting Pipe of same row of spudding in, again in the tube connector opposite side hole corresponding with the slip casting house steward of spudding in; An end that then same row's some Grouting Pipe is exposed at the roadbed outside connects with the eyelet welding corresponding with Grouting Pipe on the same tube connector respectively, the slip casting house steward is connect with the eyelet welding corresponding with the slip casting house steward on the tube connector again.
(3) at roadway excavation and Grouting Pipe draining sewer in the same way, the draining sewer is tilted to the roadbed outer rim from the median strip; Behind the excavation draining sewer, in the inboard one deck geotextiles of laying of draining sewer, use building stones to fill the draining sewer immediately, compress compacting behind 2-4 cubes of building stones of every filling, and then continue to fill, filled up by building stones until whole draining sewer.
Compared with prior art, beneficial effect of the present invention is:
Roadbed settlement slip casting punishment structure can guarantee simultaneously a plurality of Grouting Pipe to be carried out slip casting, and grouting pressure, slip casting duration that guarantees each Grouting Pipe etc. is all identical, thereby guarantees slip casting effect.The draining sewer is laid between two row's Grouting Pipe, and the draining sewer tilts to lay from the roadbed median strip at a certain angle, extends to outside the roadbed side slope.Can guarantee that draining is unobstructed, be unlikely to occur the not smooth problem of current alluvial discharge of horizontal drainage sewer.Fill rubble and compacting in the sewer, the porosity of rubble is big, is convenient to draining, and through compacting, can guarantee subgrade strength.Can guarantee the slip casting effect of a plurality of Grouting Pipe slip castings, in time discharge the ponding in the roadbed, and construction technology is simple, cheap.
