Description
Technical field
The utility model relates to one and had both been applicable to soft foundation, be applicable to again general geological structure, simultaneously there is again high-bearing capacity, and can replace cement mixing pile, reduce the protruding joint pile foundation of cement mixing-filling and the manufacturing process of pile foundation distribution density, belong to slip casting pile foundation and manufacture field.
Background technology
Current existing cement mixing pile construction method: 1) position of p ile machine, centering are put well behind agitation pile stake position, mobile mixing pile machine arrives and refers to fixed pile, centering.2) adjust leading truck verticality: adopt transit or the two-way control leading truck of ceiling hammer verticality.By design and code requirement, verticality be less than 1.0% long.3) stir in advance: start deep-mixing pile driver rotating disk, after stirring-head rotating speed is normal, can make drilling rod stir along sinking limit, leading truck limit, subsidence velocity can regulate and control by gear, and operating current should not be greater than rated value.4) mixing slurries: deep mixer stirs simultaneously in advance, backstage mixing cement grout, treats, before mud jacking, slurries are put into aggregate bin.Select the common silicate cement mixing of cement grade 425# slurries, water/binder ratio is controlled at 0.45～0.50 scope, is no less than 50Kg according to every meter of deep-mixed pile cement consumption of designing requirement.5) whitewashing is stirred and is promoted: sink to arriving after projected depth, open mortar pump, send and starch to stirring-head grout outlet by pipeline, after pulp, start mixing pile machine and tensioning chain device, stir limit by definite hoisting velocity (0.50～0.8m/min) the limit whitewashing of design and promote drilling rod, slurries and the soil body are are fully mixed and stirred.6) repeating stirring sinks: stir drill bit and be promoted to after the above 500mm height in stake top, close mortar pump, repeat stirring and sink down into projected depth, subsidence velocity is undertaken by designing requirement.7) whitewashing repeats to stir and promotes: sink to arriving after projected depth, whitewashing repeats to stir and promotes, and is promoted to ground always.8) stake machine displacement: constructed after a pile, mobile stake machine, to next pile position, repeats above step and carries out the construction of next pile.The deficiency of its existence it: the intensity difference of pile foundation, bearing capacity is little, under equal bearing capacity, needs to increase Pile Diameter and density, takes a lot of work, time-consuming, foundation pile cost of manufacture is high.
Utility model content
Purpose of design: avoid the weak point in background technology, design one had both been applicable to soft foundation, be applicable to again general geological structure, simultaneously there is again high-bearing capacity, and can replace cement mixing pile, reduce the protruding joint pile foundation of cement mixing-filling of pile foundation distribution density.
Design scheme: in order to realize above-mentioned purpose of design.1, being positioned at the slip casting pile body periphery of ground and bottom bag Li cement and mud and being uniformly mixed the design of formation solidification layer, is one of technical characterictic of the present utility model.The object of doing is like this: cement mixing pile is a kind of pile foundation for reinforced soft soil ground processing, it has realized the formation in Soft Clay condition storied building pile foundation, but not only bearing capacity is little, pile foundation distribution density is large, manufacturing cost is high, and the yield rate of pile foundation and quality cannot ensure.The application is on the basis of cement mixing pile, under the prerequisite of cement mixing boring moulding and ot-yet-hardened, grouting pile is pressed in the stake hole of cement mixing pile, after solidifying, not only make pile foundation Cheng Zaili become several times improve, and greatly reduce the distribution density of pile foundation, and yield rate and the quality of pile foundation are improved widely.2, in grouting pile, being longitudinally provided with the design of erectting Grouting Pipe, is two of technical characterictic of the present utility model.The object of doing is like this: in the time that the application's grouting pile is positioned at pile foundation hole, high pressure concrete slurry by the ground compacting of at the bottom of erectting Grouting Pipe note bottom port and injecting pile foundation hole and slurry pile foundation hole bottom after along the slip casting of upwards bursting and become muddy when a thaw sets in of slip casting pile lining, in the time that the pressure of frost boiling slip casting reaches the pressure of high-pressure slip-casting, frost boiling slip casting is automatically in halted state, the grouting pile slip casting portion of upwards bursting and become muddy when a thaw sets in forms compactness high grouting pile foundation bearing head, has greatly improved the bearing capacity of grouting pile.3, the below that the grout outlet of Grouting Pipe is erect in first segment grouting pile in more piece grouting pile (a bottom joint grouting pile) lower surface is provided with the design of peviform frost boiling dish, is three of the utility model technical characterictic.The object of doing is like this: when peviform frost boiling dish is fixed on to first segment grouting pile lower surface and peviform frost boiling dish rim and the lower surface of first segment grouting pile and is spacing and coordinates, it both can prevent that soil or sand in pile foundation hole from stopping up setting Grouting Pipe grout outlet, can force again setting Grouting Pipe grout outlet high pressure spray to go out slurry and rout up and turn over along peviform frost boiling dish, reach the compacting of first segment grouting pile bottom ground and the formation that high density, high strength are carried pile crown.
Technical scheme: the protruding joint pile foundation of a kind of cement mixing-filling, comprise grouting pile, the slip casting pile body periphery bag Li cement and the mud that are positioned at ground are uniformly mixed formation solidification layer, grouting pile bottom is for expanding a concrete pile head, multiple hoop Grouting Pipe from bottom to top hoop be embedded on the wall of grouting pile and multiple hoop Grouting Pipe respectively with erect Grouting Pipe and be communicated with, on hoop Grouting Pipe face, hoop has gunniting hole.
The utility model compared with background technology, the one, started the precedent that cement mixing pile adopts grouting pile carrying, cement slurry to solidify solid base; The 2nd, be both applicable to soft foundation, be applicable to again general geological structure, there is again high-bearing capacity, and can replace cement mixing pile completely simultaneously; The 3rd, not only greatly reduce cement consumption, and guaranteed the quality of stake; The 4th, when can completing quickly and easily the pile extension of grouting pile, not only make to hale concrete grouting stake periphery pile foundation soil property compactness and increase, and the concrete density that high-pressure slip-casting forms is large, intensity is high; The 5th, utilize waste residue to fill, both improved the stability of pile foundation surrounding geology state, reach again the making full use of of waste residue, reach the object of environmental protection, material-saving; The 6th, the pile body that the hoop Grouting Pipe of tubular pile body forms is just as Bamboo-shaped pile tube, what the concrete pipe base that Bamboo-shaped pile tube and high-pressure slip-casting form formed is the carrying of ring pile body, not only greatly improved the loaded area of pile tube, and bearing strength obtains the raising of essence.
