Description

A full set of tubular type long auger stake machine and the method for utilizing the ram machine construction
Technical field
The present invention relates to the piling Technologies in field of civil engineering, are especially a kind of a full set of tubular type long auger Stake machine and the method for utilizing the ram machine construction full set tubular type long auger guncreting pile.
Background technology
With the development of national economic development and the progress of piling Technology, the pile foundation of soft soil foundation is also increasingly Extensively.In the bored concrete pile type of existing pile foundation technology, long auger guncreting pile is not necessarily to mud off, without squeezing soil due to having Effect, environment protecting are good, penetration power is strong, high efficient construction, obtain promotion and application more and more.
Long auger guncreting pile is by long auger stake machine pore-forming.The long auger stake machine of the prior art includes Chassis, mainmast, long screw drill rod, power head, hoist engine, traction rope and pumping concrete auxiliary device, mainmast are fixed on chassis On, power head is slidably matched with mainmast, and mast top is equipped with fixed pulley, and hoist engine connect with traction rope one end, traction rope around The other end for crossing fixed pulley and traction rope is fixed with power head, and long screw drill rod is fixed on power head lower end, and pumping concrete is attached to be set Standby conveying pipeline is connected to the core pipe of long screw drill rod, and valve is equipped at the drill bit of core pipe bottom end.Hoist engine winds or loosens Traction rope so that power head drives long screw drill rod to rise or fall.The long spire is call general in industry, refers to brill From top to bottom all equipped with helical blade on the outer circumference surface of the core pipe of bar.
Work progress using traditional stake machine is:Power head drives drilling rod rotation to drill downwards, and the soil body is by spiral in hole Blade, which pushes up, moves to ground, and after drilling reaches designed elevation, concrete material is conveyed into drilling rod core pipe by pumping concrete auxiliary device, Core pipe bottom end valve is opened in realization device to hole under concrete material Gravitative Loads and fills concrete, and drilling rod is promoted while pumping concrete, until boring Head point reaches earth's surface, is finally inserted steel reinforcement cage pile.
It the stake machine of the prior art and is had the following defects using the method for this machine bored pile:1, drilling machine in miscellaneous fill and It is easy collapse hole when being crept into the higher soil layer of level of ground water, and surrounding soil is easy the water burst into hole, moreover fills concrete into hole When concrete material in cement mortar is readily permeable causes to be lost in the surrounding soil body;2, the process of steel reinforcement cage is inserted into it is difficult to ensure that is inserted into is vertical Degree, steel reinforcement cage are easy to insert partially, cause the concrete cover thickness deviation around steel reinforcement cage big.
Invention content
The invention solves a technical problem be to provide one kind and bore in miscellaneous fill and the higher soil layer of level of ground water Into when, will not collapse hole, will not water burst, cement mortar when avoiding filling concrete in concrete material be lost in the soil body, and can guarantee insertion steel reinforcement cage When do not insert inclined a full set of tubular type long auger stake machine.
The technical solution of the present invention is to provide a kind of a full set of tubular type long auger stake machine, it include chassis, Mainmast, long screw drill rod, upper power head, first hoist and the first traction rope, mainmast are fixed on chassis, upper power head Be slidably matched with mainmast, mainmast be equipped with the first fixed pulley group, one end of the first traction rope connect with first hoist and The other end is fixed around the first fixed pulley group with upper power head, and long screw drill rod is fixed with upper power head;Under this machine further includes Power head, second hoist and the second traction rope, mainmast are additionally provided with the second fixed pulley group, and lower power head is also slidably fitted in master On mast, and one end of the second traction rope connect the other end with second hoist and consolidates around the second fixed pulley group and lower power head Fixed, lower power head is removable to be connected with a full-sleeve concentric with long screw drill rod, and lower power head is equipped with drilling rod via, long Auger stem passes through drilling rod via to be inserted into full-sleeve.
The invention solves another technical problem be to provide one kind in miscellaneous fill and the higher soil layer of level of ground water When drilling, will not collapse hole, will not water burst, the cement mortar of concrete material is lost in the soil body when avoiding filling concrete, and can guarantee insertion steel reinforcement cage When do not insert a full set of tubular type long auger guncreting pile of inclined construction method.
Another technical solution of the present invention is to provide a kind of side of a full set of tubular type long auger guncreting pile of construction Method, step include:
A, a full set of tubular type long auger stake machine is in place, so that the drill bit of long screw drill rod is directed at pile foundation center, and correct The verticality of long screw drill rod and its concentricity with full-sleeve;
B, long screw drill rod drives lower to soil body drilling in upper power head, and full-sleeve drives lower and long spiral shell in lower power head Rotary drill bar synchronous rotary sinks to the soil body, and during synchronous sinking, drill bit is lower than full-sleeve;Long screw drill rod drilling process In, the soil body rises at lower power head along the helical blade of long screw drill rod and is discharged;
C, after the drill bit of long screw drill rod reaches bottom hole projected depth, core of the pumping concrete auxiliary device through long screw drill rod Then pipe pump concrete, and continue 20s or more continues pumping, guncreting on one side rotating the while of pulling up long screw drill rod, Until the drill bit of long screw drill rod is lifted higher than the position of design of pile top absolute altitude, pressure filling process terminates;
D, the connection for unclamping lower power head and full-sleeve makes the two be detached from, and full-sleeve is stayed in stake position, then by stake Machine is removed so that empty accessible above stake position;
E, steel reinforcement cage is inserted into the concrete of stake position with joint bar device;
F, vibrating bin is hung with loop wheel machine, vibrating bin is moved at the top of stake position, vibrating bin and full-sleeve are connected and fixed, then Full-sleeve is extracted while vibrating.
Full set tubular type long auger stake machine of the invention and utilize the ram machine construction full set tubular type long auger guncreting pile Method compared with prior art, has the following advantages and effect.
First, during being bored under long screw drill rod, full-sleeve synchronizes, that is to say, that full-sleeve is drill-through under Always play the role of retaining wall in journey, collapse hole when this just effectively prevents creeping into miscellaneous fill and the higher soil layer of level of ground water Situation, and the water of the soil body is obstructed by full-sleeve outside hole, has also just prevented water burst in hole;Equally, in the mistake of guncreting Cheng Zhong, full-sleeve are avoided that the soil body penetration to outside hole of the cement mortar in hole, the cement mortar for avoiding concrete material are lost in the soil body;Condition And since the top of full-sleeve is above ground level, guiding role can be played when being inserted into steel reinforcement cage, it is ensured that steel reinforcement cage is aligned in full-sleeve The heart i.e. align piles position center, the shape for preventing the concrete cover of steel reinforcement cage caused by being inserted partially due to steel reinforcement cage in uneven thickness Condition.
