Abstract
The utility model relates to a kind of dado structure of deep alluvion foundation mesohigh injection slip casting pore-forming.The deep alluvion foundation mesohigh that the purpose of this utility model is to provide a kind of simple in structure, easy construction sprays the dado structure of slip casting pore-forming, to solve in deep alluvion foundation the problem that causes collapse hole in high pressure jet grouting pore-forming because of complex formation (local built on stilts, material composition is loose etc.).The technical solution of the utility model is: a kind of deep alluvion foundation mesohigh sprays the dado structure of slip casting pore-forming, in injected hole, insert and the protection casing of injected hole aperture adaptation, it is characterized in that: in described protection casing, insert the PVC floral tube easily being smashed by high speed water, air-flow.This practicality is newly applicable to the similar engineerings such as deep alluvion foundation high pressure jet grouting processing.
Description
Technical field
The utility model relates to a kind of dado structure of deep alluvion foundation mesohigh injection slip casting pore-forming.Be applicable to the similar engineerings such as deep alluvion foundation high pressure jet grouting processing.
Background technology
For deep alluvion foundation, when covering layer material forms evenly, when grating is good, in high pressure jet grouting boring, adopt sleeve pipe follow-up to be just easy to pore-forming, when but complicated when formation material composition, local built on stilts phenomenon is serious, overlap joint is comparatively loose between particle, adopt conventional will going wrong with casing drilling pore-forming mode, because in the time that sleeve pipe is extracted, hole wall will there will be and cave in, and the boring completing is by ineffective.
Summary of the invention
The technical problems to be solved in the utility model is: for the problem of above-mentioned existence, the dado structure that provides a kind of deep alluvion foundation mesohigh of simple in structure, easy construction to spray slip casting pore-forming, to solve in deep alluvion foundation the problem that causes collapse hole in high pressure jet grouting pore-forming because of complex formation (local built on stilts, material composition is loose etc.).
The technical scheme that the utility model adopts is: a kind of deep alluvion foundation mesohigh sprays the dado structure of slip casting pore-forming, in injected hole, insert and the protection casing of injected hole aperture adaptation, it is characterized in that: in described protection casing, insert the PVC floral tube easily being smashed by high speed water, air-flow.
Between described PVC floral tube and protection casing, there is gap.
Described protection casing diameter is 178mm, and PVC floral tube diameter is 146mm.
The beneficial effects of the utility model are: the utility model adopts PVC floral tube secondary retaining wall, make sleeve pipe extract rear PVC floral tube and can provide lateral support to the soil body, avoid collapse hole, and in the time of slip casting, can adopt water, air-flow at a high speed that PVC floral tube is smashed, thereby not affect the diffusion of slurries.The utility model dado structure has solved in deep alluvion foundation the problem that causes collapse hole in high pressure jet grouting pore-forming because of complex formation (local built on stilts, material composition is loose etc.) well, this processing method has improved efficiency of construction, reduce construction investment, for carrying out high pressure jet grouting construction method on deep covering layer, new approach is proposed, for similar engineering provides a kind of new thinking, there is certain application value.
Brief description of the drawings
Fig. 1 is elevational schematic view of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the present embodiment is the dado structure that a kind of deep alluvion foundation mesohigh sprays slip casting pore-forming, is made up of: Part I is high pressure jet grouting hole 1 three parts, and aperture, an array pitch of injected hole are selected according to engineering actual conditions; Part II is the protection casing 2 of conventional boring, and this sleeve plug is suitable with injected hole aperture in injected hole 1; Part III is the secondary retaining wall that adopts PVC floral tube 3, and PVC floral tube 3 diameters are little and easily smashed by high speed water, air-flow compared with protection casing 2 diameters, and PVC floral tube is coaxially placed in protection casing 2, between this PVC floral tube and protection casing 2, has gap, is convenient to sleeve pipe and extracts.It is 178mm that general high voltage is sprayed protection casing 2 diameters in mortar depositing construction, and PVC floral tube 3 diameters adopt 146mm.
In the time that drilling depth reaches designing requirement, extract drilling rod 4, complete transferring of PVC floral tube 3, then extract protection casing 2, make sleeve pipe extract rear PVC floral tube 3 and can provide lateral support to the soil body, avoid collapse hole.When slip casting, water, air-flow at a high speed smashes PVC floral tube 3, thereby do not affect the diffusion of slurries.
