Specific embodiment
The utility model is described further below with reference to embodiment.The explanation of following embodiments is only intended to help to manage Solve the utility model.It should be pointed out that for those skilled in the art, not departing from the utility model principle Under the premise of, several improvements and modifications can be made to this utility model, these improvement and modification also fall into the utility model In scope of protection of the claims.
The design of two fluid grouting core pipe 1 first, two fluid grouting core pipe 1 by three pipelines, top mortar leakage prevention section 4, under Portion's mortar leakage prevention section 2 and middle part slip casting section 3 form.Wherein three pipelines are respectively A liquid pipe 8, B liquid pipe 6 and penstock 7, In The pipeline of 4 or more top slip casting section uses hose material, and part uses tube material below.A liquid pipe 8 and B liquid pipe 6 pass through upper For portion's mortar leakage prevention section 4 to middle part slip casting section 3, it is anti-that penstock 7 passes through lower part mortar leakage prevention section 2, middle part slip casting section 3 and top Spillage section 4.Penstock 7 respectively leads to rubber stopper 15 and secondary stop grouting plug 21 by water pressure passage 14.Two fluid grouting core pipe 1 is divided It is three sections, can dismounts, conveniently repair.
Middle part slip casting section 3 is slip casting core space, secondary stop grouting plug 21, the second sealing nut 13 including upper and lower side, the One sealing nut 5, mixing slip casting storehouse 19, mixing slip casting storehouse 19 are connected and fixed by bolt 16.It mixes 19 surrounding of slip casting storehouse and rubber is set Leather washer 18, it is ensured that spillage does not occur for mixing slip casting storehouse 19.It mixes slip casting storehouse 19 and is equipped with slurry outlet 17.Middle part slip casting section Slurries mixing bunker 19 in 3 can be dismantled, and A liquid pipe 8 and B liquid pipe 6 are each led into wherein, so that slurries mix in storehouse, later It is directly injected into stratum, mixed serum is reduced and is stopped in Grouting Pipe too long and stifled a possibility that starching occurs.Even if stifled slurry occurs Situation also only appears in slurries mixing bunker 19, can solve stifled slurry by disassembly, cleaning or replacement mixing bunker in this way Problem, not will cause construction delay and equipment loss is serious.As shown in Figure 2,3.
Top mortar leakage prevention section 4 and lower part leakproof section 2 are passed through penstock 7, and penstock 7 by water pressure passage 14 with Rubber stopper 15 connects.
The upper, middle and lower of two fluid grouting core pipe 1 three are partially contained in together on the ground, by tightening the first sealing nut 5 Penstock 7 is set to complete sealing.Then A liquid pipe 8 is connected by the second sealing nut 13, B liquid pipe 6 is also by the second sealing nut 13 connections.Then slurries mixing bunker 19 is fixedly connected by bolt 16, and guarantees that slurries mixing bunker 19 is fully sealed.Again will Two fluid grouting core pipe 1 is inserted into mini-valve tube 10, the depth location for needing slip casting is positioned by sounding mark device 9, accurately Slip casting is realized in different depth in ground.
When two fluid grouting core pipe 1 reaches designated depth, hydraulic pressure is given by penstock 7, makes rubber stopper 15 and secondary only slurry Plug 21 all expands, and forms sealing slurry check ring.Then by external double-fluid grouting machine, the liquid of two kinds of different ratios is respectively pressed into A liquid pipe 8 and B liquid pipe 6, two kinds of slurries reach to be mixed in slurries mixing bunker 19, is then driven into surrounding by slurry outlet 17 Inside soil body realizes the reinforcing to surrounding soil.At the end of the depth slip casting is fast, a certain slurries are closed, carry out it only single There is only single liquid in slurries mixing bunker 19, in this way when two fluid grouting tube core 1 replaces, will not block in liquid injection Phenomenon.
It when changing slip casting position, needs to lay down water pressure in time, then changes the position of two fluid grouting core pipe 1, then again It repeats the above steps.
After the completion of slip casting, two fluid grouting core pipe 1 is taken out, A liquid pipe 8 and B liquid pipe 6 are squeezed into clear water and carry out washing pipe, later will Slurries mixing bunker 19 opens cleaning.It is not in plugging phenomenon by using the two fluid grouting core pipe 1.Even if blocking, It only occurs in slurries mixing bunker 19.And slurries mixing bunker 19 can dismantle cleaning and replace, and also can fast and effectively handle stifled The case where plug, occurs.
