Wherein based on the dry construction method for digging implant module of peg board formula roadbed tubular pole, comprising the following steps:

A, it is implanted into steel pile casting: steel pile casting and rotary digging power head is detachably fixed to the cylindrical tube shape knot for connecting into a monoblock type Structure；Downward pressure is rotated and applied by rotary digging power head, it will be among the axial vertical implantation ground of steel pile casting to realize；And it plants The steel pile casting entered protrudes from ground and circumferentially clamps top by clamping anchor ear, then tears steel pile casting and rotary digging power head open Point；

B, single group steel pile casting splices: after being detachably fixed connection by rotary digging power head and another steel pile casting again, and it is mobile Onto the steel pile casting of implantation ground, after two steel pile castings are detachably fixed connection by dormant bolt, clamping anchor ear is unclamped again, And the steel pile casting spinning on top is implanted by ground by rotary digging power head；Same construction method general-a steel pile casting is implanted into ground In after, the top steel pile casting protrudes from ground and circumferentially clamps top by clamping anchor ear；

C, dry to scrape out hole: rotary digging power head is detachably fixed with augers to be connect；And by augers in steel pile casting Interior sidetracking is dug, while being taken out of soil by the spiral edge wing of augers, thus by being embedded in 2-3 steel pile casting of ground Soil hollows out；

D, the splicing of multiple groups steel pile casting and the dry hole that scrapes out: augers is removed, the step of carrying out A, B, C is repeated, with this reality Show the implantation of 6-7 root steel pile casting and the soil in steel pile casting is hollowed out, and forms a dry borehole；Meanwhile upper end steel pile casting is prominent Top is circumferentially clamped on ground and by clamping anchor ear；

E, high-pressure slip-casting: grouting pipe positioning is placed among dry borehole with lifting appliance, and the bottom of grouting pipe The bottom of grout outlet and dry borehole is correspondingly arranged；High pressure concrete slurries are through connector injection at the top of grouting pipe and to dry borehole Dry borehole is filled after bottom squeeze on the outside of pipe, after the water in dry borehole is squeezed out and fills up dry borehole, takes out grouting pipe；

F, it extracts steel pile casting out: rotary digging power head and the upper end steel pile casting of implantation is detachably fixed connection；And start rotary digging Power-equipment pulls steel pile casting to move up, and so that axial end portion is detachably fixed the prominent ground of connection structure, and by clamping anchor ear The steel pile casting wall of next section is clamped, then artificial by spanner dismounting dormant bolt, then passes through rotary digging power-equipment for a upper section Steel pile casting transhipment；Similarly, all steel pile castings are extracted out；

G, it is implanted into tubular pole: tubular pile hoop being detachably fixed with rotary digging power head and is connect, and a root canal pile of realization pair Axial grip；It is pressed into concrete slurry vertically in the rotating down pressing of self gravity and rotary digging power-equipment by tubular pole In, and pass through the upper end of the tight tubular pole of grasping firmly hoop clip；Clamping another tubular pole by tubular pile hoop makes the tubular pole of its bottom and embedment Upper axial is correspondingly arranged, and after two opposite exposed steel bars of tubular pole are welded and fixed, then passes through the tubular pile hoop band at top In dynamic two tubular pole precession concrete slurries being fixedly connected, waiting for its solidification quietly can be realized the implantation of tubular pole.

Above-mentioned construction first carries out protecting tube embedding on the basis of common spiral-digging pore in boring procedure, steel pile casting with Rotary digging power head connection, bury casing with drilling depth in boring procedure, can effectively solve sand section carry out it is dry scrape out hole, Meet the dry hole that scrapes out of design to require；The present invention using rotary drilling rig lifting tubular pipes, can reduce crane by disassembly rotary digging power head Cooperate lower pile driving construction, increases construction efficiency；The present invention passes through churning driven by increasing hydraulic anchor ear in churning driven power head part After machine hangs stake, rotary digging power head is passed through, holds tubular pole tightly using the increased hydraulic anchor ear of churning driven power head, stake under static pressure type can Mechanical arm vibration hammer coordinative construction is reduced, construction efficiency is increased, and solves former vibration hammer blow tubular pile not positioning in the process, is put down The defects of face position and more accurate degree control, positioning is more convenient, and substantially increases tubular pole verticality, and process is more Simply, convenient for operation.

The present apparatus also can be used for the clamping in tube pile construction and position, in the structure setting and utility model specifically positioned The specifically setting of steel pile casting is identical；Also it can be used for the clamping of the dismountable wellbore part of other tubulars, it is applied widely.

Existing construction pulls out similar experience without steel bushing, therefore corresponding anchor ear is arranged according to casing diameter, on anchor ear Hydraulic device is added, casing can be fixed, after pulling out Partial Height using rotary digging rotation, the hydraulic anchor ear of steel pile casting is recycled to embrace Tight casing, is pressurizeed using rotary digging, can effectively solve the problems, such as the disassembly during steel pile casting is pulled out.The utility model structure is simple, It is convenient for disassembly and assembly, when leaving unused, the hoop of device is split, convenient for storage and transport, when use can carry to working site into Luggage is matched, and entire assembling process job area very little, entire installation and use process it is highly-safe and time saving and energy saving, It is very convenient, working range can be effectively isolated, protect the safety of staff, and greatly improved work efficiency； Present apparatus structure is simple, more convenient to the installation operation of steel pile casting, reusable, economical and practical, easy to carry, management, Using flexible, design is rationally, compact-sized, is suitble to be widely popularized.
