A kind of lattice-pile foundation, comprises the foundation pile 2 being placed in underground, is connected to the basis, ground 1 on foundation pile top; It is characterized in that, be interconnected by diaphragm wall 3 between described foundation pile 2, form one in integrally-built underground foundation; Underground foundation by with foundation pile 2 for node, with the diaphragm wall 3 arranged continuously downwards from earth's surface for connector, the cross section formed with foundation pile 2 and diaphragm wall 3 be netted grating texture body for elementary cell, jointly connect expansion and formed.
Further, described foundation pile 2 lower end is provided with the expansion pile top 4 that cross-sectional area increases; The lower end of diaphragm wall 3 is provided with the Extended chemotherapy 5 of cross-sectional area increase, and the longitudinal section of diaphragm wall 3 adopts variable cross-section structure.
Further, described expansion pile top 4 and Extended chemotherapy 5 are positioned in same level, expand pile top 4 and are connected as a whole with the mutual correspondence of Extended chemotherapy 5.
Further, the horizontal plane of described Extended chemotherapy 5 is higher than the horizontal plane expanding pile top 4, and Extended chemotherapy 5 and corresponding foundation pile 2 are interconnected as a whole.
Further, basis, described ground 1 be cushion cap or raft foundation or box foundation or continuous grade beam.
Further, the subsection reinforcement device 6 for section construction is provided with in described diaphragm wall 3; Described subsection reinforcement device 6 comprises reinforcing bar 601 and steel pipe 602, and the external diameter of steel pipe 602 is not more than the thickness of diaphragm wall 3, and run through uniformly from top to bottom and be provided with some reinforcing bars 601 being parallel to diaphragm wall 3 and arranging, concrete seven has been built in inside; Reinforcing bar 601 free end of adjacent subsection reinforcement device 6 is interlaced, and is built by concrete seven and link together.
Further, the external diameter of described steel pipe 602 equals the thickness of diaphragm wall 3, and steel pipe 602 wall being parallel to diaphragm wall 3 is provided with some through holes 603 for flowing out part concrete seven.
A construction method for lattice-pile foundation, is characterized in that, is completed by following steps:
A. the construction line-putting location, determines the accurate location of each foundation pile 2 by construction lofting;
B. beat base pile hole, utilize existing pile hole construction instrument to complete the excavation of base pile hole;
C. segmentation fluting, utilizes grooving tool, centered by the base pile hole described in step b, to base pile hole direction segmentation fluting adjacent in length and breadth, and adopts bracing or strutting arrangement segmentation to support;
D. settle cage of reinforcement, described in step c with segmentation fluting and the foundation pile broken charges of the cell body that supports of segmentation and its correspondence settles cage of reinforcement;
E. segmentation is built, in the base pile hole placing cage of reinforcement described in step and cell body, concreting 7 forms foundation pile 2 and corresponding diaphragm wall 3, and by cage of reinforcement free end expose the concrete seven suitable length of building, for adjacent reinforcing bar bridge joint stubble;
F. form lattice-pile foundation, form one in integrally-built underground foundation to after the program of each base pile hole successively whole completing steps c to e, basis 1 is on the ground set on the top of underground foundation, finally forms lattice-pile foundation.
Further, the grooving tool described in step c segmentation fluting is pneumatic slotting drill, and described bracing or strutting arrangement is support air bag or subsection reinforcement device 6.
Further, described step b to e can complete in order successively for same base pile hole, can carry out for different base pile holes simultaneously.
Of the present inventionly aim to provide a kind of lattice-pile foundation, slotted by pneumatic slotting drill between the foundation pile 2 of underground, form dark narrow foundation ditch, foundation ditch lower end is carried out end and is expanded formation enlarged footing, build with reinforcing bar skeleton concrete seven in foundation ditch, form the diaphragm wall 3 connecting foundation pile 2, the degree of depth several meters of lattice-pile foundation is to tens meters, original pile foundation is connected with each other by diaphragm wall, form the entirety formed for elementary cell expansion with netted grating texture body, be similar to current box-structure, but difference is: foundation pile 2 of the present invention and diaphragm wall 3 and surrounding rock body 8 acting in conjunction, need not overall excavate, then backfill, can direct control, rock mass 8 in lattice-pile foundation keeps original state, good integrity, and become to be integrated with lattice-pile foundation, make the good rigidity of lattice-pile foundation, flexing resistance is strong, load is large, and also owing to need not overall excavate, therefore the degree of depth is far longer than current box foundation, and therefore basic stability, safety outclass box foundation, also greatly reduce cost.
A kind of lattice-pile foundation of the present invention and construction method thereof, its beneficial effect is:
1) in order to reach the mechanical requirements of design in original pile foundation, the diameter of stake is all comparatively large, and with increases such as depth of buildings; But it is overall owing to adopting diaphragm wall 3 to be therewith interconnected to become a stressed lattice between foundation pile 2 of the present invention, therefore the diameter of foundation pile 2 can reduce greatly, and sectional of constructing completes, thus large quantities of materials is saved, owing to adopting fluting, the arrangement of reinforcement equipment of specialty, speed of application is fast, shortens the duration that concrete seven is built greatly.
2) surface area of the lattice-pile foundation described in the present invention expands to cover the peripheral area of diaphragm wall 3 from the peripheral area of single pile, much larger than the surface area of existing pile foundation, thus shaft resistance is large, and friction bearing capacity is large; The pile top of each foundation pile 2 can adopt and expand pile top 4 simultaneously, and thus the bearing capacity of pile top cannot complete the pile-type of end expansion much larger than other; Therefore, the bearing capacity of lattice-pile foundation of the present invention improves greatly, under identical requirement, greatly reduces the operation of construction, accelerates construction speed.
3) lattice-pile foundation described in the present invention, due to the overall structure that underground foundation is a not digging up and filling in, be engaged in the basis, ground 1 that underground foundation top is formed again, therefore the flexural stress suffered by it and shearing force can not focus on independently on foundation pile 2, but shared by entirety, the ability of bending resistance shearing resistance is far longer than other foundation structure, the disease that thorough elimination conventional infrastructure differential settlement causes, considerably increase the shock resistance of building simultaneously, be specially adapted to the basis of high level or super high rise building.
