Technical field
The utility model relates to a kind of grouting device that uses in the grouting and reinforcing test.
Background technology
In order better to verify the result of small size test, better simulated field execution conditions, make the composite chemical grouting reinforcement technique move towards precision, scientific, must carry out more deep research to the slip casting process, can not satisfy actual requirement far away to the research of slurry injection technique method both at home and abroad at present.
Documents and materials show that the Ge Jialiang of Huainan Mining Industry College had once set up an indoor grouting device in 1997, and its apparent size is 600 * 400 * 234mm, is mainly used in studying crack rock slip casting.In addition, do not see the relevant report of setting up indoor large simulation grouting device both at home and abroad as yet.
Summary of the invention
In order to carry out indoor grouting simulation test, there is not the technical matters of actual available test unit again, the utility model can satisfy the slip casting situation under the different grouting process, grouting parameter, slurries parameter condition of the sand body of on-the-spot geologic condition.
Technical solution of the present utility model is as follows:
A kind of lab simulation slip casting test unit, comprise grouting pipe, grouting pump and stir liquid storage cylinder, its special character is: also comprise two die sinkings and be arranged on the interior sand sample layer of two die sinkings, the described pair of die sinking be a pair of symmetry the lobe mould, these both sides to the lobe mould are respectively arranged with bolt hole on extension, make this connect fastening to the lobe mould by corresponding bolt.
Above-mentioned valve is is shaped as C shape.
The material of above-mentioned valve is aluminium alloy.
Above-mentioned grouting pipe comprises body and is arranged on the obstruction of body front end that described body is provided with the spout hole that diamond-mesh distributes.
Totally 3 pairs of above-mentioned spout holes.
Above-mentioned grouting pump is manual pressure test pump.
Above-mentioned stirring liquid storage cylinder is provided with visual window.
The beneficial effects of the utility model:
1, the utility model has remedied the defective that lacks testing equipment when the slip casting situation of simulated field sand under different grouting pressures, grouting amount, slurries condition, utilize this testing equipment can analyze correlationship and slip casting effect between the grouting parameter, use in order to better carry out on-the-spot slip casting.
2, the wide function of the utility model purposes is many, can be fit to the grouting simulation test of different medium, installs lightly, and dirigibility easy for installation is good.

Embodiment
The utility model is as the device of grouting simulation test, carry out indoor large scale (diameter * highly: 300mm * 620mm) test, the feasibility of checking grouting program, obtain diffusion radius and the slip casting corrected parameter of composite chemical grouting and reinforcing body, for its on-the-spot solid model experimental study, site operation parameter determine and the construction feasibility analysis is carried out the initial stage and is prepared research work.
A kind of lab simulation slip casting test unit, comprise grouting pipe, grouting pump and stir liquid storage cylinder 4, as shown in Figure 1, large-scale split cavity of the present utility model, comprise a pair of C shape aluminium alloy lobe mould 1, be respectively arranged with three pairs of bolts hole on this radially extension to C shape aluminium alloy lobe mould 1 both sides, make this connect fastening to C shape aluminium alloy lobe mould by corresponding bolt 2.
As shown in Figure 2, grouting pipe 3 of the present utility model, by long l=0.8m, φ 40x2.5mm weldless steel tube is made, front end stalloy solder up, in body 32 leading portion 200mm scopes, 3 couples of φ 6mm of quincuncial arrangement spout hole 31, form 6 spout holes altogether, the weldless steel tube rear end is connected with the test pump Grouting Pipe; Grouting pump is manual pressure test pump, and model is SYL13/16.
Process of the test is: elder generation cleans C shape aluminium alloy lobe mould and keeps dry, and one deck separant is smeared by portion within it; Install 6 pairs of bolts, split cavity is closely connected.Place the grouting pipe of making in advance in the position of split cavity sand sample height 1/2, add split cavity with the sand sample layering this moment, require to divide 3 times sand sample all to be added, and with large-scale compaction hammer on request with the sand sample compacting, use test pump to carry out slip casting then.During the property advanced test, note following some:
(1) stablizes grouting pressure.In the engineering, generally be to adopt large-scale air compressor machine as the slip casting power source, pressure is more stable, and discharge pressure is general constant in 0.8MPa.The hydraulic coupling that goes out of grouting pump generally big luffing occurs with the variation on stratum.In the practical operation, should regulate the grouting pump air intake valve at any time in good time according to manometric variation and slip casting face condition, regulate to give and press size, suitably reduce the possibility that slurries are got through new fissure-plane.
(2) suitably adjust grouting amount.Got through or stratum itself just exists under the situation in crack when the crack, suitably increase grouting amount filling crack, the existence that can alleviate because of fissure-plane causes the not good phenomenon of grouting consolidation effect.
(3) suitably increase slip casting hole count, minimizing grouting hole distance.Increase the overlapping scope that adjacent hole adds solid, guarantee to add the whole slip casting effect of solid.
