Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Embodiment one:A kind of high-pressure rotary-spray long spire combination rig, as shown in Figure 1 and Figure 2, the rig include long screw auger Machine fuselage, drilling rod, ash can 5.Drilling rod is connected on the unit head 1 of drilling machine body, and ash can 5 is welded on rig arm 20, right Answer construction equipment to be placed in be threadedly coupled with unit head 1 by pipe on the ground.When carrying out water-stop curtain Construction of High Pressure Jet Grouting Pile, High-pressure rotary-spray drilling rod 2 is installed on the unit head 1 of former long-spiral drilling machine fuselage and replaces long screw drill rod 16, high-pressure rotary-spray drilling rod 2 End is provided with shower nozzle 3 and drill bit 4.Because common high-pressure rotary-spray drilling machine body volume ratio is larger, and common long-spiral drilling machine The volume of fuselage is less than high-pressure rotary-spray rig, so high-pressure rotary-spray drilling rod 2 is arranged on the dynamic of long-spiral drilling machine fuselage by us To replace high-pressure rotary jetting apparatus fuselage in power first 1, cost of transportation is so effectively saved.Ash can 5 has been welded on rig arm 20, There is perforate to run through high-pressure rotary-spray drilling rod 2 on ash can 5.When carrying out Construction of High Pressure Jet Grouting Pile, due to pressure-air and height Water Cutting, displacement are pressed, it will produce substantial amounts of soil cement slurry, so welding ash can 5 on rig arm 20.Ash can 5 is iron System, top, which is provided with circular hole 7, bottom centre, is provided with case eaves 6 and material hole 8, and material hole 8 is identical with the axle center of circular hole 7.High pressure is revolved Spray drilling rod 2 makes shower nozzle 3 and drill bit 4 in ash can 5 through circular hole 7.During construction, the bottom of ash can 5 keeps level with ground, opens This rig is moved, high-pressure rotary-spray drilling rod 2 can be passed from material hole 8, pierce the earth, drive shower nozzle 3 to be worked with drill bit 4, and high pressure is revolved The cement puddled soil produced during spray can be flowed out by the effect of pressure from the hole got out, when height of the cement puddled soil outside hole is more than During the height of case eaves 6, cement puddled soil can be flowed into ash can 5, and is blocked by case eaves 6.Case can be attached in view of cement puddled soil On eaves 6, cause influence cement puddled soil to flow into ash can 5, used oil lubricating layer need to be coated on the inside and outside wall of case eaves 6, make its table Face is smooth, and is not reacted with cement puddled soil.
Unit head 1 is provided with high pressure cement slurry inlet 9, ground and placed on high-pressure injection pump 11, high-pressure injection pump 11 Provided with water under high pressure slurry outlet 10 and cement slurry inlet 12.Cement slurry inlet 12 is inserted in cement mortar stirring pool 13, and cement mortar is stirred The cement conduit 15 mixed on the opposite side placement cementing tank 14 in pond, cementing tank 14 is inserted in cement mortar stirring pool 13.During feeding, spiral shell Line connection high pressure cement slurry inlet 9 and water under high pressure slurry outlet 10, cement mortar stirring pool 13 is imported by the cement in cementing tank 14 In be stirred, then cement mortar is passed through in unit head 1 by high-pressure injection pump 11.After Construction of High Pressure Jet Grouting Pile terminates, High-pressure rotary-spray drilling rod 2 is dismantled and long screw drill rod 16 is installed, then by the concrete charging aperture and high pressure on concrete mixer Cement slurry inlet is threadedly coupled, and carries out CFG pile driving constructions.
During installation, on the unit head 1 that high-pressure spiral bar 2 is arranged on to long-spiral drilling machine fuselage, shower nozzle 3 and drill bit 4 are set Put on high-pressure rotary-spray drilling rod 2, then set according to the length of the distance of high-pressure rotary-spray drilling rod 2 to rig arm and long screw drill rod 16 Count iron ash can 5 and open up circular hole 7 and material hole 8, then ash can 5 and ground level are welded on rig arm 20.Construction When, the cement conduit 15 on cementing tank 14 is inserted in cement mortar stirring pool 13, the water under high pressure mud on high-pressure injection pump 11 goes out Mouth 10 is threadedly coupled high pressure cement slurry inlets 9, and cement slurry inlet 12 is then inserted in cement mortar stirring pool 13.Make in cementing tank 14 Cement is passed through in cement mortar stirring pool 13 and stirred, and then starts high-pressure injection pump 11, cement mortar is entered unit head 1 In.Now high-pressure rotary-spray drilling rod 2 passes through circular hole 7 and material hole 8, and the shower nozzle 3 and drill bit 4 of end are constructed in soil.High pressure is revolved After spray pile driving construction terminates, high-pressure rotary-spray drilling rod 2 is dismantled, then the long screw drill rod 16 with helical blade 17 is installed, continues CFG The construction of stake.
Embodiment two:A kind of high-pressure rotary-spray long spire combination rig, as shown in Figure 3, Figure 4, the embodiment and embodiment one Difference be that the connection of ash can 5 and rig arm 20 connects to rotate.Two connecting plates 1 are welded on rig arm 20, are given up A connection 2 23 is welded on hopper 5, three connecting plates are connected by hinge 22.The advantage of embodiment two is ash can 5 Highly without necessarily achieving the degree for the helical blade 17 that can load on long screw drill rod 16, also, when drilling rod is changed, only need Pass through hinge 22(Bolt passes through connecting plate one and the attaching nut of connecting plate two)Ash can 5 is rotated, drilling rod is then changed .
Described above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
