Abstract
The invention relates to rig, the particularly a kind of invention that can bore a complete set of tubular type rig in post hole, various building foundation.The main body of rig is to be formed in parallel by two steel sleeves, the length of sleeve pipe can increase by joint, the top of sleeve pipe connects the outlet pipe of water inlet pipe respectively, inside pipe casing has conduit, a underground electric borer is respectively adorned in the bottom of sleeve pipe, but connect expansion bit below the electric drill, the high-velocity flow of sending here from water pump directly washes away excavation surface and takes away boring mud.Being pressed into and extracting by a cover hydraulic means of sleeve pipe finished.After rig got into desired depth, under the motionless situation of sleeve pipe, drill bit electric drill conduit etc. can be extracted in advance, so as in sleeve pipe descending reinforcing cage, concrete perfusion.
Description
The invention relates to rig, the particularly a kind of invention that can bore a complete set of tubular type rig in various building foundation piles hole.
Driven pile, silent piling and bored pile are several main method in present bridge harbour, industry and the civilian construction foundation construction, and this several method respectively has characteristics, use all quite extensive.But also all also there are some problems.Vibration is big during the driven pile construction, noise is big, and is bigger in the harm of area, densely populated areas, urban centre especially.In addition, slotting preformed pile reinforcement ratio and concrete grade of beating is all higher.So it is high material consumption cost height, if then higher with the piling bar cost; Silent piling is owing to be subjected to pile press itself to be pressed into the restriction of power, and stake footpath and stake are dark all restricted.In addition because static pile press structure more complicated, from great, accessory is many, cost an arm and a leg, and applies also being restricted.Bored pile, no matter be to use direct circulation, still anti-circulation all must be prepared a large amount of mud, mud can serious environment pollution in the city.The hole expansibility of general drilled pile is bigger in addition, and the stake cross sectional shape is rule not too, the difficult control of verticality of the quality of stake and stake.
Task of the present invention provides a kind of driller.Its performance is better than existing rig, utilizes it can create a kind of new building foundation pile construction method.
Task of the present invention is that following mode is finished: the main body of this rig is to be formed in parallel by two steel sleeves, and the length of sleeve pipe can increase by joint.A loam cake is arranged at the top of sleeve pipe, connects water inlet pipe and outlet pipe respectively, and the inside of sleeve pipe also has a conduit.One of underground electric borer is respectively adorned in the bottom of sleeve pipe, connects a variable-diameter drill bit below the electric drill.
Characteristics of the present invention are: a kind of device is arranged at underground electric borer top, and after rig got into desired depth, under the motionless situation of sleeve pipe, drill bit, electric drill and conduit can be transferred in advance, so as in sleeve pipe descending reinforcing cage, concrete perfusion.
Another characteristics of the present invention are: the hydraulic means that a cover was pressed into and transferred to sleeve pipe is housed on the support.
Dual-tube driller has following advantage:
1, two sleeve pipes form the U-shaped tubulose, and water inlet pipe is identical with the scum pipe bore, and it is effective that the high-velocity flow that water pump is sent here directly washes away the development end deslagging, so penetration rate is fast, efficient is high.
2, a complete set of pipe bit advances, and does not need mud off, available clear water circulation deslagging, and the spending of both having saved preparation mud can not produce mud contamination again, can also prolong the life-span of pump greatly.
3, friction, noiseless even can construct in densely populated urban district in one day 24 hours.
4, except the rock stratum, any soil property is all applicable.Even in soft foundation, can not cause the hole that collapses yet.Also can construct near the existing building place.
5, Zhuan cross sectional shape rule, concrete quality is guaranteed, and reinforcing bar can not expose, and pile quality is reliable.Because the reinforcement ratio and the concrete grade of stake can suitably reduce, the cost of stake also just can reduce.
6, the stake that is drilled to dual-tube driller, its cross section such as knob I-shaped, the garden stanchion identical with sectional area compared, and the bearing capacity and the counter-bending ability of stake improve a lot.
7, can bore taper pile with dual-tube driller.Boring, descending reinforcing cage, concrete perfusion are all carried out easily.
8, adopt dual-tube driller to connect a mode of taking, can make colonnade formula diaphragm wall.
9, dual-tube driller is simple and reliable for structure, technology maturation, power demand is littler than machinery of the same type, can be used for the land, operation on the water again, be a kind of economy, energy-conservation, broad-spectrum construction machinery.
Accompanying drawing has been described one embodiment of the present of invention.
Accompanying drawing 1: dual-tube driller organigram.
Accompanying drawing 2: the cross sectional shape of the stake that dual-tube driller is drilled to.
Fig. 1 has described dual-tube driller.Its organic block (1) is provided with small arc shaped frame (2) electric block (3) travel mechanism (4) oil pump (5) pulpit (6) etc. thereon, being pressed into and transfering to by jack unit (8) of sleeve pipe (7) finished, and the top of sleeve pipe has loam cake (9) to tap into water pipe (10) and outlet pipe (11) respectively; Respectively there is a conduit (12) inside of sleeve pipe; A underground electric borer (13) respectively is equipped with in the bottom of sleeve pipe; The water circulation deslagging that connects drill bit (14) rig below the electric drill is finished by water pump (15).
Claims (3)
1, rig, particularly a kind of energy bore a complete set of tubular type rig in various building foundation piles hole.Its main body is to be formed in parallel by two steel sleeves (7), the length of sleeve pipe can increase by joint, the top of sleeve pipe has loam cake (9) to tap into water pipe (10) and outlet pipe (11) respectively, the inside of sleeve pipe respectively has the bottom of a conduit (12) sleeve pipe a diving respectively to be housed by boring (13), the bottom of electric drill connects drill bit (14), and the water circulation deslagging of rig is finished by water pump (15).
2, according to the rig of claim 1, it is characterized in that: a kind of device is arranged at underground electric borer top, and after rig got into desired depth, under the motionless situation of sleeve pipe, drill bit underground electric borer and conduit can be transferred in advance.
