Description
Technical field
The utility model is related to engineering equipment field more particularly to a kind of note sand devices.
Background technology
China is that earthquake disaster one of the countries with the most serious ..., earthquake often threaten engineering safety in the world.Current China
New Earthquake Activity Periods are in, earthquake occurrence frequency increases, this constitutes the infrastructure construction that China is flourishing
It seriously threatens.Therefore, in earthquake prone areas building constructure or structures, it is necessary to handle possible liquefaction earth.
There are three conditions for soil liquefaction, first, soil necessarily is in saturation state；Second is that there is the dynamic loading of certain condition；Third,
Soil itself is liquefying soil.In order to avoid soil liquefaction threatens building safety, the way in engineering be using extruding shake it is close,
Change fill out, the methods of cement mixing method consolidated subsoil soil；But these ways mostly put into it is larger, and as time goes by also
It will appear new hidden danger.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of new note sand devices, and the liquefying soil in soil is transformed
Layer, eliminates the liquefaction hidden danger of foundation soil.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of note sand device, including holder,
Jet pipe, shaft, driving device, water pump and blade；
Vertical rack-mount of jet pipe, holder is Liftable type, and multiple nozzles are provided on the tube wall of jet pipe；
Shaft is mounted in jet pipe, and shaft is concentric with jet pipe, in driving device mounting bracket, the rotation of driving device drive shaft
Turn, turns the tip of the axis and be hinged more blades；
Water pump passes through hose connecting spray nozzle, coarse sand ingress pipe connection flexible pipe.
The utility model note sand device application method be：
(1) it drills on ground, drilling depth should reach liquefiable soil layer or less；
(2) jet pipe and shaft are stretched into drilling, adjusts the height of holder so that nozzle is directed toward liquefiable soil layer；
(3) water pump is opened, high pressure water flow strikes liquefiable soil layer is utilized；
(4) coarse sand is injected into flow by coarse sand ingress pipe, coarse sand and impacts the fine sand to get off from liquefiable soil layer
Mixing；
(5) it properly increases the height of holder and opens driving device, the shaft and blade of rotation are sufficiently stirred coarse sand and thin
Sand.
Further, valve is installed on the coarse sand ingress pipe.
Further, the holder is supported by multiple hydraulic cylinders, and hydraulic cylinder is used to adjust the height of entire holder.
Further, the driving device is motor.
Advantageous effect：Coarse sand is injected the liquefiable of foundation soil using jet pipe and shaft by the note sand device of the utility model
Coarse sand and liquefiable soil layer are sufficiently mixed and are eventually converted into non-liquefaction soil layers by soil layer, eliminate the later stage liquefaction of foundation soil
Hidden danger improves the safety of engineering construction.
Description of the drawings
Fig. 1 is the structural schematic diagram of 1 note sand device of embodiment.
Wherein：1, holder；2, jet pipe；3, shaft；4, motor；5, water pump；6, blade；7, hydraulic cylinder；8, nozzle；It 9, can liquid
Change soil layer；10, hose；11, coarse sand ingress pipe；12, valve.
Specific implementation mode
The utility model is described in further detail With reference to embodiment.
Embodiment 1
As shown in Figure 1, the note sand device of the present embodiment, including holder 1, jet pipe 2, shaft 3, motor 4, water pump 5 and blade
6；
Jet pipe 2 is vertical to be mounted on holder 1, and the quadrangle of holder 1 is supported by hydraulic cylinder 7 respectively, is set on the tube wall of jet pipe 2
It is equipped with multiple nozzles 8；
Shaft 3 is mounted in jet pipe 2, and shaft 3 and jet pipe 2 are concentric, and in 4 mounting bracket 1 of motor, motor 4 passes through driving cog
Wheel drive shaft 3 rotates, and the end of shaft 3 is hinged more blades 6；
Water pump 5 is by 10 connecting spray nozzle 2 of hose, 11 connection flexible pipe 10 of coarse sand ingress pipe, is equipped on coarse sand ingress pipe 11
Valve 12.
The present embodiment note sand device application method be：
(1) it drills on ground, drilling depth should reach 9 or less liquefiable soil layer；
(2) as shown in Figure 1, jet pipe 2 and shaft 3 are stretched into drilling, the height of holder 1 is adjusted so that the direction of nozzle 8 can
Liquefaction soil layers 9；Blade 6 at this time is in contraction state；
(3) water pump 5 is opened, high pressure water flow strikes liquefiable soil layer 9 is utilized；
(4) Open valve 12 inject coarse sand into flow by coarse sand ingress pipe 11, coarse sand with from liquefiable soil layer 9
The fine sand mixing impacted；
(5) start hydraulic cylinder 7, properly increase the height of holder 1 so that blade 6 reaches the position of liquefiable soil layer 9, so
Motor 4 is opened afterwards, and the shaft 3 and blade 6 of rotation are sufficiently stirred coarse sand and fine sand.
Although the embodiment of the utility model is illustrated in specification, these embodiments are intended only as carrying
Show, should not limit the scope of protection of the utility model.Various omissions are carried out in the range of not departing from the utility model aims, are set
It changes and change should be included in the scope of protection of the utility model.
