Description
Technical field
The utility model relates to pit mining a kind of two fluid grouting mixing arrangement used.
Background technology
Increase along with the pit mining degree of depth must cause the rising of roadway surrounding rock stress, the corresponding increase of deformation of the surrounding rock in tunnel amount, thus causes roadway surrounding rock broken, and country rock is loose, and roadway damage is serious, shows that tunnel produces serious distortion, as tunnel wall caving, pucking.Be directed to supporting roadway surrounding rock, domestic and international support expert carry out a large amount of theoretical researches due to colliery tunnel support and are subject to the impact of complex geologic conditions, add that current coal mining depth day by day increases, the form of the destruction in tunnel is more complicated, broken serious when running into some roadway surrounding rocks, country rock is soft, re-use these traditional supporting method and supporting is carried out to breaking surrounding rock tunnel with copying mechanically and applying indiscriminately, just can not form stable bearing structure, in time supporting being carried out to the tunnel of mode of failure complexity according to original supporting method, during often after supporting, mining dynamical pressure affects, tunnel produces serious wall caving, pucking, crush serious, the serious safety in production that have impact on colliery.
Along with the progress of science and technology, for a current breaking surrounding rock roadway support difficult problem, domestic and international expert proposes the breaking surrounding rock support technology that slip casting combines with cable bolting, first Bolt-beam-steel Mesh Support System is carried out to tunnel, then carry out slip casting secondary supporting, after slurries inject breaking surrounding rock by grouting pump, slurries filling country rock internal crack, and carry out cementing to the country rock body that cracking is broken, the crack that breaking surrounding rock inside is formed disappears, country rock reverts to the non-individual body with complete structure, after breaking surrounding rock recovers continuity, high-strength anchor cable applies the fringe conditions of high strength to it, the country rock after slip casting is made to have stronger supporting capacity, stop country rock again to destruction, guarantee the roadway surrounding rock monolithic stability after reinforcing.
At present for breaking surrounding rock slip casting many employings two fluid grouting, main employing be rapid hardening early strong aluminium sulfate base grouting material and polyurethanes chemical material, these materials have the early strong feature of rapid hardening, generally be made up of two kinds of components, single liquid resting period is longer, can rapid solidification after the two mixing, and requires that mixed proportion is 1: 1, but traditional grouting device cannot complete the grouting with plunger of this kind of material, namely allow to effect and do not reached expection.
Utility model content
The utility model object is to provide a kind of two fluid grouting mixing arrangement, and it can solve problem existing in background technology effectively.
In order to solve problem existing in background technology, the mixing tube 1 that it comprises two-liquid grouting device and is attached thereto, described two-liquid grouting device comprises two single fluid grouting pipes 2, be connected by tee junction 3 between described mixing tube 1 with two single fluid grouting pipes 2, the other end of institute's single fluid grouting pipe 2 is provided with ball valve 5, one way valve 4 is installed in the middle part of it, described single fluid grouting pipe 2 is provided with flow meter 6, this flow meter 6 is between tee junction 3 and one way valve 4, relief valve 7 is provided with between described one way valve 4 and tee junction 3, the middle part of described mixing tube 1 is provided with static mixer 8, described static mixer 8 comprises blender shell 9, hybrid blade 10 is mounted with in this blender shell 9.
Owing to have employed above technical scheme, the utility model has following beneficial effect: structure is simple, easy to use, because the middle part of single fluid grouting pipe is provided with one way valve, one way valve can protect single fluid grouting pipe and pump, single fluid grouting pipe and pump generation blocking accident can be prevented, and can prevent two kinds of slurries from can not produce grout leaking; Can be dismantled Grouting Pipe soon by relief valve pressure release after slip casting terminates, ensure that the safety of construction; Equip flow meter respectively at single fluid grouting pipe, be used for monitoring the flow of slurries in single liquid pipe, pinpoint the problems and can solve in time, prevent from affecting slip casting effect because slurries do not reach 1: 1; Two kinds of slurries can mix before combination fully, owing to installing static mixer on mixing tube, thus can realize reasonable mixed effect, effectively ensure that the plugging effect of spillage passage and the intensity of grouting and reinforcing.
