Description
Technical field
The utility model belongs to delamination pour slurry technical field of construction equipment in geotechnical engineering, relates to a kind of delamination pour slurry rifle.
Background technology
Delamination pour slurry is the boring of certain depth of constructing in ground, inoculated sleeve shell material, mini-valve tube is set, mini-valve tube will forever be stayed in the soil body, and mini-valve tube sidewall offers multiple grout outlet, and the outer wall having grout outlet overlaps rubber sleeve, during slip casting, the slip casting core pipe of band plugging device is inserted in mini-valve tube, slip casting is carried out to needs slip casting part, as shown in Figure 1.In the soil body, produce the Seed harvest of holing as core like this, and form the strong tree root of shear resistance netted slurry arteries and veins complex in the peripheral soil mass crack of pile body, wherein in Fig. 1, the brief introduction of delamination pour slurry equipment main composition material is as follows:
(1) sleeve shell material: select swell soil or clay, cement is Portland cement;
(2) mini-valve tube: adopt the unidirectional mini-valve tube of screw thread, manufactured by polyethylene, mini-valve tube inner wall smooth, outer wall has longitudinal direction and ring stiffener to improve rupture strength, and its two ends are screwed connection, on mini-valve tube, often joint has
grout outlet some (see Fig. 1), surface cover rubber sleeve outside porose position, rubber sleeve is covered with grout outlet, utilizes pressure to make slurries enter stratum by grout outlet during slip casting, water and soil stone granulate in stratum is difficult to enter in mini-valve tube, reaches the one way valve effect of mini-valve tube;
(3) slip casting core pipe: the steel pipe of employing or galvanized pipe, often saves two screwed connection, long 100 ~ 150cm, and slip casting core pipe leaves slurry outlet, and slip casting core pipe two ends add leather cup type rubber stopper respectively, form two way seal.
There is following problem in existing delamination pour slurry rifle:
(1) slip casting effect is poor: existing delamination pour slurry rifle utilizes rubber stopper to reach the object of delamination pour slurry, depthkeeping slip casting, and in Practical Project, gap between rubber stopper and mini-valve tube inwall is difficult to be effectively controlled, grouting pressure does not reach designing requirement, part sleeve shell material fails open loop, does not reach predetermined slip casting effect;
(2) efficiency of construction is low: because rubber stopper and mini-valve tube inner wall size are difficult to effective coupling in process of production, therefore rubber stopper size is seldom had can to meet grouting effect at the construction field (site), the collateral resistance that rubber stopper and mini-valve tube inwall can be made again to produce controls at zone of reasonableness, occurs that two kinds of more problems are: between a rubber stopper and mini-valve tube, tension makes slip casting core pipe move up and down difficulty in site operation process; There is space between two rubber stoppers and mini-valve tube must change rubber stopper and increase unnecessary work, above two kinds of phenomenons all greatly reduce site operation efficiency.
Summary of the invention
The utility model, in order to overcome the defect of prior art, devises the delamination pour slurry rifle that a kind of slip casting effect is good, efficiency of construction is high.
The concrete technical scheme that the utility model is taked is: a kind of delamination pour slurry rifle, be arranged in mini-valve tube, comprise slip casting core pipe, slip casting core pipe and mini-valve tube coaxially arrange and leave gap between mini-valve tube and slip casting core pipe, on slip casting core tube wall, cover has two rubber stoppers, be respectively rubber stopper and lower rubber stopper, slip casting core pipe sidewall between two rubber stoppers offers multiple slurry outlet, the sidewall of mini-valve tube between two rubber stoppers offers multiple grout outlet, the outer wall offering the mini-valve tube of grout outlet overlaps rubber sleeve, key is: set up/air pump of fetching water, upper rubber stopper is the upper rubber stop grouting plug with import and outlet, lower rubber stopper is the lower rubber stop grouting plug with import, to fetch water/the inlet communication of gas delivery side of pump and upper rubber stop grouting plug, the outlet of upper rubber stop grouting plug and the inlet communication of lower rubber stop grouting plug, upper rubber stop grouting plug and lower rubber stop grouting plug be all by fetching water/air pump is in expansion or contraction state, slip casting core pipe seals by being in the upper rubber stop grouting plug of swelling state and lower rubber stop grouting plug and mini-valve tube clamping.
Described to fetch water/be provided with the first water under high pressure/tracheae between air pump and upper rubber stop grouting plug, the import of the first water under high pressure/tracheae and/outlet, the outlet of the first water under high pressure/tracheae and the inlet communication of upper rubber stop grouting plug of air pump of fetching water.
