Embodiment 1
As it is shown in figure 1, embodiments of the invention 1 provide a kind of grouting device 001 being applicable to sand soil foundation ditch, should
Grouting device 001 includes anchor pole 100 and the slip casting machine 200 of hollow, and one end of anchor pole 100 is provided with drill bit 110, and anchor pole 100 is adjacent
Nearly drill bit 110 one end sidewall offers at least one injected hole 120, and anchor pole 100 is inserted with away from drill bit 110 one end can be vertically
The depression bar 130 of movement, the outer wall of depression bar 130 is provided with at least one cannelure 132, is equipped with O shape and seals in each cannelure 132
Circle 133.In anchor pole 100 between depression bar 130 and drill bit 110, vacancy is pressurizing chamber 140, and depression bar 130 offers slip casting passage
131, anchor pole 100 is provided with sealing-plug 150 away from one end of drill bit 110, and sealing-plug 150 offers for connecting injected hole 120 He
The passage 151 of slip casting passage 131, slip casting machine 200 is connected with pressurizing chamber 140 with slip casting passage 131 by passage 151, depression bar 130
It is also associated with the grouting pressure adjusting part 300 for opening and close slip casting passage 131.
The use step of the grouting device 001 that the present embodiment provides is: be first inserted in sandy soil foundation ditch by anchor pole 100
In the hole accomplished fluently, make anchor pole 100 have one end of drill bit 110 downwards, and the afterbody applying pressure of anchor pole 100 is made anchor pole 100
It is fixed in sandy soil foundation ditch, with injecting screened sand or mountain skin sand, the hole will accomplished fluently in sandy soil foundation ditch around backward anchor pole
Fill and lead up, water in a small amount of water makes hole the sand moistening filled in；Subsequently depression bar 130 is inserted in anchor pole 100 certain position solid
Fixed, slip casting machine 200 is connected with the slip casting passage 131 offered in depression bar 130 by Grouting Pipe, subsequently will by slip casting machine 200
Serosity passes sequentially through Grouting Pipe, slip casting passage 131, pressurizing chamber 140 and injected hole 120 and is injected in sandy soil foundation ditch neighbouring anchor pole
In the sandy soils of 100.
As in figure 2 it is shown, grouting pressure adjusting part 300 includes sealing lid 310 and elastic component 320, the two ends of elastic component 320
Connect seal cap 310 and depression bar 130 respectively.Elastic component 320 in the present embodiment is spring, and anchor pole 100 is adjacent to drill bit 110 one end
Sidewall offers two injected holes 120 being arranged symmetrically with.
The principle of grouting pressure adjusting part 300 is: when in slip casting passage 131, pressure is more than pressure in pressurizing chamber 140,
Slip casting passage 131 is opened；When in slip casting passage 131, pressure is less than or equal to pressure in pressurizing chamber 140, slip casting passage 131 envelope
Close.When slip casting machine 200 does not injects grout in pressurizing chamber 140, pressure and pressure phase in slip casting passage 131 in pressurizing chamber 140
Deng, spring promotes and seals lid 310 sealing slip casting passage 131, and when slip casting machine 200 starts to inject serosity, slip casting passage 131 is intrinsic pressure
Power is more than pressure in pressurizing chamber 140, and serosity promotes sealing lid 310 to overcome spring tension to open, slip casting passage 131 and pressurizing chamber
140 connections, serosity makes pressurizing chamber 140 in being injected into pressurizing chamber 140 in, pressure increases, until pressure is more than note in pressurizing chamber 140
In slurry passage 131 during pressure, seal lid 310 and reclose slip casting passage 131.

Enough effectively improve sealing, it is to avoid serosity is revealed from the space between depression bar 130 and anchor pole 100 inwall.Outside depression bar 130
Wall arranges cannelure 132, arranges O-ring seals 133 in cannelure 132, keeps the sealing of depression bar 130 and anchor pole 100 inwall,
During avoiding slip casting, serosity is revealed.
The grouting device 001 that the present embodiment provides also includes DC source, and anchor pole 100 and exhaust tube 400 all use and lead
The metal material of electricity is made, and the positive pole of DC source electrically connects with anchor pole 100, and the negative pole of DC source is electrically connected with exhaust tube 400
Connect.When using this grouting device 001 slip casting, open DC source, thus at anchor pole 100, form positive pole, at exhaust tube 400
Form negative pole, the serosity of slip casting adds electrolyte solution, when serosity is injected in sandy soils by anchor pole 100, due to
The electroosmosis of exhaust tube 400, fraction slurries can at exhaust tube 400 diffusion, thus improve grouting device 001 and be injected into
The range of scatter of the serosity in sandy soils.
The grouting device 001 that the present embodiment provides can make the soil layer being diffused into anchor pole 100 surrounding that serosity is stable: simultaneously
Air extractor 500 extracts gas in sandy soils by the exhaust tube 400 being plugged in the sandy soils of anchor pole 100 surrounding, makes anchor pole
The sandy soils internal gas pressure of 100 surroundings declines, and improves the relative pressure of anchor pole 100 slip casting, it is possible to improve the diffusion of serosity further
Area, it is possible to use the both positive and negative polarity of DC source to connect anchor pole and the exhaust tube of conduction respectively, improve slurry by electroosmosis
The diffusion area of liquid.
