Description
Technical field
The utility model relates to a kind of porous grouting device, and especially a kind of porous parallel-connected grouting device that is applicable to reinforcing roadway weak surrounding rock belongs to roadway weak broken wall rock support engineering field.
Background technology
The weak surrounding rock grouting process in recent years at home and abroad the colliery tunnel support field obtain to a certain degree application, its objective is by the grouting filling wall-rock crack, broken sillar gluing is reinforced whole, fully improve the self-bearing capacity of country rock, improve supporting effect, in the big tunnel of water yield, also can play the effect of water blockoff antiseepage.But there is following problem in the existing grouting process in colliery: 1. injected hole adopts single rectangular arrangement mode, and slurries at first to the crack infiltration of comparatively growing, have stoped the reinforcing to the hypotonicity argillaceous soft rock; 2. adopt the construction of low discharge grouting pump single hole, speed is slow, efficient is low, has become the bottleneck of tunnel speedy drivage; 3. owing to lack the control method of slip casting process, often cause in the operation to lack and annotate, leak and annotate, do not reach the grouting quality requirement; 4. some mine is arranged the operation simultaneously of a large amount of personnel and equipment for satisfying schedule requirement, causes personnel and hold facility, and normal tunneling construction is produced bigger influence.
Summary of the invention
Technical problem: the purpose of this utility model provides a kind of simple in structure, and injection speed is fast, efficient height, the effective porous parallel-connected grouting device that is used for reinforcing roadway weak surrounding rock.
Technical scheme: the utility model is used for the porous parallel-connected grouting device of reinforcing roadway weak surrounding rock, comprise mixer, liquid storage mixer, grouting pump, grouting pipeline, flow 〉=the 52L/min of described grouting pump, grouting pump is connected with the multistage slip casting controller of controlling many grouting pipelines through large diameter Grouting Pipe, and control valve, pressure meter, flowmeter that multistage slip casting controller is located on many grouting pipelines by current divider, are respectively successively formed.
Described many grouting pipelines are 3～9; The internal diameter of described large diameter Grouting Pipe is about 50mm.
Beneficial effect: the utility model adopts the electronic grouting pump of big flow, substitutes the pneumatic grouting pump of former low discharge, and flow rate of grouting is more than 4～5 times of original technology; Adopt multistage slip casting controller, simultaneously 3～9 Grouting Pipe are implemented continuous slip casting, the slip casting simultaneously of the big flow of realization-pump porous by current divider; Pressure meter, flowmeter and control valve all are housed on every grouting pipeline, each bar grouting pipeline is controlled respectively, respectively each grouting pipeline of finishing slip casting in the different time is carried out the slip casting of next circulation, improved the speed and the effect of slip casting greatly.The utility model one pump porous slip casting simultaneously and working continuously improves injection speed more than 3～9 times, and each grouting pipeline is realized instant control, improves the arrangement of injected hole, improves grouting quality, guarantees the roadway grouting supporting effect.Full advance moon progress 80m, than former U shaped steel totally-enclosed supporting moon progress raising 20m, supporting effect is good, and the tunnel does not have distortion substantially.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a multistage slip casting controller architecture schematic diagram of the present utility model.
Among the figure: 1-mixer, 2-liquid storage mixer, 3-grouting pump, 4-major diameter footpath Grouting Pipe, the multistage slip casting controller of 5-, 6-grouting pipeline, 7-grouted anchor bar, 5-1-current divider, 5-2-control valve, 5-3-pressure meter, 5-4-flowmeter.
The specific embodiment
Porous parallel-connected grouting device of the present utility model, mainly constitute by mixer 1, liquid storage mixer 2, grouting pump 3, large diameter Grouting Pipe 4, multistage slip casting controller 5 and many grouting pipelines 6, wherein mixer 1 links to each other with liquid storage mixer 2, and grouting pump 3 links to each other with liquid storage mixer 2; Adopting the flow 〉=52L/min of grouting pump 3 is big flow grouting pump; Many grouting pipeline 6 is 3～9; The internal diameter of major diameter Grouting Pipe 4 is about 50mm.The grouting pump 6 of big flow is connected with the multistage slip casting controller 5 of controlling many grouting pipelines 6 through large diameter Grouting Pipe 4, and control valve 5-2, pressure meter 5-3, flowmeter 5-4 that multistage slip casting controller 5 is located on many grouting pipelines 6 by current divider 5-1, respectively successively form.Major diameter grouting pipeline 4 is divided into many grouting pipelines 6 through multistage slip casting controller 5 provides slurries, multistage slip casting controller 5 can monitor in real time and control each bar grouting pipeline 6 respectively, connect the grouted anchor bar 7 that the quincunx cloth of array pitch hole is provided with between a plurality of pressing respectively by many grouting pipelines 6, simultaneously a plurality of injected holes are implemented slip casting.
During work, in the good a plurality of injected holes of construction, grouted anchor bar 7 is installed respectively, then with rapid setting cement or hole packer sealing of hole, the degree of depth 〉=300mm of sealing of hole; Afterwards, select the electronic grouting pump 3 of flow 〉=52L/min for use, major diameter Grouting Pipe 4 by connecting electronic grouting pump 3, through multistage slip casting controller 5 with the slurries that prepare simultaneously via many grouting pipelines 6 and each grouted anchor bar 7 injection hole that links to each other with many grouting pipelines 6 respectively of connecting thereon in, the enforcement porous parallel-connected grouting; In the process of implementing slip casting, by observing flow rate of grouting table 5-4 on the multistage slip casting controller 5 and the data of pressure meter 5-3, flow and the pressure that each grouting pipeline 6 injects slurries is held in support respectively, when wherein hole slurries no longer flow, and the grouting pressure that pressure meter 5-3 shows reaches 2MPa when above, close the control valve 5-2 of this pipeline, this grouting pipeline 6 taken off be connected on the next grouted anchor bar, implement the slip casting of next injected hole, circulation successively, switch each grouting pipeline 6 respectively, realize porous parallel-connected grouting.
