Abstract
The invention discloses a grate type prestressed tubular pile supporting structure, which consists of a concrete tubular pile and a #-shaped concrete grate. A hole for the concrete tubular pile to penetrate through is arranged at the cross position of the #-shaped concrete grate, wherein steel bar frameworks are both arranged in the concrete tubular pile and the #-shaped concrete grate. The single-connection concrete tubular pile and the #-shaped concrete grate at the upper portion are combined to form a framework system of the supporting structure, thereby fully playing prestressing effect of the concrete tubular pile, reducing lateral deformation of a non-prestress reinforcement structure, decreasing usage of concrete and steel bars for a concrete tubular pile with equivalent supporting effect, being quick in construction speed, and saving construction cost.
Description
Technical field
The invention belongs to the realm of building construction, particularly a kind of grid type pile for prestressed pipe supporting and protection structure.
Background technology
When soft base and deep foundation ditch operation, all extensively adopt concrete perfusion pile tube campshed at present as supporting and protection structure; Be that concrete tubular pile adopts the mode that is set up in parallel; To form a zone of protecting with concrete tubular pile in the operation area, cave in the earth that prevents the operation area periphery.When deep foundation ditch, then adopt with the structure of prestressed anchor collocation and carry out pattern foundation pit supporting structure, be provided with screw thread, anchor pole is inserted in the soil body, and put channel-section steel, channel-section steel is fixed, fix cheating wall basically with nut in the outer end of anchor pole in the outer end of anchor pole.Yet increase along with soft basic distortion strength increase or foundation depth; The diameter that then must increase concrete tubular pile to be to play more firm effect, will corresponding increase reinforcing bar and concrete consumption after the concrete diameter increases, also can increase engineering quantity simultaneously; So just will certainly increase engineering cost; Simultaneously anchor pole then will increase difficulty of construction when running into the rear hard hard thing is arranged, even have influence on the actual effect of anchor pole, and then influence workmanship.
Summary of the invention
In order to solve the deficiency of existing supporting and protection structure; The present invention provides a kind of grid type pile for prestressed pipe supporting and protection structure, and this supporting and protection structure not only can play effective support action, and can promote supporting effect; Reduce reinforcing bar and concrete consumption simultaneously, practice thrift the duration.
The present invention realizes through following technical proposals: it is made up of concrete tubular pile and groined type concrete grid; Infall at groined type concrete grid is provided with the hole that can supply concrete tubular pile to pass; Wherein in concrete tubular pile and groined type concrete grid, be equipped with cage of reinforcement, and groined type concrete grid is the integral one-step molding structure.Utilize the groined type concrete grid on single-unit prestressed concrete pipe pile and top to be combined to form the frame system of supporting and protection structure, give full play to the prestressing effect of concrete tubular pile.
The invention has the beneficial effects as follows: not only can play effective support action, and can promote supporting effect, reduce reinforcing bar and concrete consumption simultaneously, practice thrift the engineering-built cost, be convenient to promote the use of.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described further.
Fig. 1 is a perspective view of the present invention.
Fig. 2 is a plan view from above of the present invention.
Code description among the figure: 1 concrete tubular pile; 2 groined type concrete grids; 3 preformed holes; 4 tie-beams.
The specific embodiment
Like Fig. 1, shown in Figure 2; Concrete tubular pile (1) is separately positioned on the place, preset stake position of construction area; Successively concrete tubular pile is passed in the preformed hole (3) from its pairing groined type concrete grid (2) respectively then, groined type concrete grid is fixedly connected into an integral body by tie-beam (4).After wherein any concrete tubular pile receives lateral pressure; Its active force all can be passed in the whole support system through groined type concrete grid; Thereby decomposed the pressure that the single-unit pile for prestressed pipe is born, given full play to the prestressing effect of concrete tubular pile.In practice; For improving resistance to tension of the present invention; In concrete tubular pile and groined type concrete grid, be equipped with cage of reinforcement; And groined type concrete grid is the integral one-step molding structure, and the while, the reinforcing bar amount of in concrete tubular pile and groined type concrete grid, using was also many more along with the increase of the foundation depth of its supporting.
