Abstract
A kind of cross castinplace pile and piling method thereof, the section of perfusion pile body is cross.The piling method feature is to adopt special-purpose machinery grab bucket grooving, the across slotted eye; With slurry coat method cycle operation cleaning pile bottom sediment; On the foundation pile pile body, during the constructing structure post, the steel pipe locator is set on steel pipe top.The steel pipe locator is provided with the adjustment bolt, can adjust the verticality of steel pipe and steel pipe locator.Advantage is, bearing capacity of single pile improves, and the sedimentation displacement reduces, and adopts existing construction of continuous concrete wall plant construction, all operations on the ground, stake, construction molding of post.Be applicable to various bored concrete pile foundation constructions.
Description
The invention belongs to the cast-in-place concrete pile and the bore forming method thereof of the stake in the Foundation Design, particularly cross section.
At present, in the foundation construction of building, often adopt cast-in-place concrete pile, the section of castinplace pile mostly is round, and its piling method is to adopt auger machine boring, perfusion mud off, descending reinforcing cage, concrete perfusion, pile.Along with the development of industry with civilian construction, some piles and industrial premises require the bearing capacity of stake bigger, and bearing stratum is darker.When building has the multilayer underground structure, often need construction underground structure post on the pile body of round foundation pile, just need foundation pile that bigger bearing capacity is arranged this moment.
The bearing capacity of round section driven cast-in-place pile, be subjected to the restriction of its construction technology and section configuration, can not be very big, this is because the bearing capacity of the foundation pile of round section depends on due to cross-sectional area and the peripheral length, therefore need to change the section configuration of stake, to improve the bearing capacity and the frictional resistance of stake.Simultaneously, the piling method of circle cross section castinplace pile adopts machine drill boring at present, utilizes rig to fetch earth, and need join special-purpose machines and tools in addition for stake point soil (being pile bottom sediment) and clear up, and also brings the loaded down with trivial details of construction.
When building had the multilayer underground structure, existing job practices was machine drill boring, the pouring foundation pile is provided with casing on foundation pile, personnel are lowered in the casing, the working face of cleaning foundation pile, the center of calibration structure post is provided with the structural column steel pipe, the concrete of reperfusion structure post, casing is removed in segmentation again, be that foundation pile and structural column are the gradation perfusions, it is loaded down with trivial details to construct, and personnel are safety inadequately.
In the construction of underground structure, as the supporting barricade, often adopt continuous underground wall structure, the construction of continuous concrete wall method is to adopt special-purpose machinery grab bucket grooving, creep mud off, descending reinforcing cage, pouring underwater concrete, moulding.When the slurry coat method cycle operation, needn't change plant, just can eluriate and clean out the sediment at the bottom of the continuous wall groove, guarantee that the diaphragm wall substrate is solid, enough bearing capacities are arranged.Can be used to solve the sediment cleaning of castinplace pile.
The objective of the invention is, design a kind of castinplace pile of cross section,, reduce sedimentation and deformation to improve bearing capacity of single pile; Adopt the range of equipment equipment cutting slots of construction of diaphragm wall, cleaning sediment, pouring underwater concrete, pile, can realize the grooving of cross stake, not change facility and clear up stake point soil, stake, post one-shot forming immediately, avoid underground work, handled easily, safe construction.
Cross castinplace pile of the present invention by reinforcing cage and concrete form, is characterized in that, the pile body section of castinplace pile is cross, horizontal, vertical two to aileron be orthogonal;
The piling method of cross castinplace pile of the present invention is, grooving, and retaining wall, descending reinforcing cage, pouring underwater concrete is characterized in that, adopts special-purpose machinery grab bucket grooving, becomes cross slotted eye; When mud off, with slurry coat method cycle operation cleaning pile bottom sediment;
When constructing structure post on the foundation pile pile body, its piling method is that employing special-purpose machinery grab bucket grooving becomes cross slotted eye; With slurry coat method cycle operation cleaning pile bottom sediment; Following cross foundation pile reinforcing cage; Hang steel pipe column, insert in the reinforcing cage its lower end, on steel pipe top the steel pipe locator is set; After adjusting contraposition, following tremie is to stake trench bottom, pouring underwater concrete; When underwater concrete is filled into foundation pile design elevation place, drop into rubble, push down the concrete surface of cross section part; Continuation is at the pipe top of pouring concrete within steel pipe to steel pipe, pile.
The steel pipe locator is made up of locating flange, framework, cat ladder, on the upper and lower crossbeam of framework, be symmetrical arranged 4 locator verticality and adjust leading screw, on the middle cross beam of framework, be symmetrical arranged 4 steel pipe verticality and adjust bolt, on the framework top panel, be symmetrical arranged 4 steel pipe horizontal movements around the locating flange and adjust bolt.
The advantage that the present invention has is, the stake of the more round section of castinplace pile of cross section, and bearing capacity is improved, and the sedimentation displacement reduces greatly; Adopt existing construction of continuous concrete wall plant, needn't be equipped with drilling machine and scarfing cinder equipment, stake, post one-shot forming, cost saving, easy to operate; Needn't personnel's underground work, construction safety is reliable.
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of cross castinplace pile
Fig. 2 is the A-A sectional drawing of Fig. 1
Fig. 3 is a steel pipe locator constructional drawing
Fig. 4 is that the piling method of cross castinplace pile is implemented illustration
As seen from the figure, when the lid of underground construction dug reverse construction, the aileron section of cross castinplace pile 1 was 300 * 60 centimetres, and dark 30 meters, at 17 meters of the degree of depth, steel pipe 2 diameters that are connected to structural column are 630 centimetres.The piling method of cross castinplace pile is:
The grab bucket grooving, excavate horizontal, vertical aileron groove after, become cross slotted eye;
Mud off, slurry coat method are filled with whole slotted eye;
Start the mud circulation pump, utilize the cycle operation of slurry coat method, the cleaning pile bottom sediment;
Descending reinforcing cage is to bottom land;
Hang steel pipe column, insert in the reinforcing cage its lower end, on steel pipe top the steel pipe locator is set, adjust the steel pipe horizontal movement earlier and adjust bolt, adjust the adjustment leading screw of verticality of steel pipe locator and the adjustment bolt of steel pipe verticality again, adjust the steel pipe column center, and locate after the center of foundation pile;
Following tremie is to the stake end, pouring underwater concrete;
Underwater concrete is filled into the design elevation (promptly-17 meter) of foundation pile and locates, and throws in rubble on cross section, pushes down concrete surface;
In steel pipe, continue concrete perfusion, to the mouth of pipe of steel pipe, pile.
The steel pipe locator is made up of locating flange 3, framework 4, cat ladder 5, on the upper and lower crossbeam of framework, be symmetrical arranged 4 locator verticality and adjust leading screw 6, on the middle cross beam of framework, be symmetrical arranged 4 steel pipe verticality and adjust bolt 7, on the framework top panel, be symmetrical arranged 4 steel pipe horizontal movements around the locating flange and adjust bolt 8.
