Abstract
The invention discloses a kind of grid type pile for prestressed pipe supporting and protection structure, it is made up of concrete tubular pile and groined type concrete grating, be provided with the hole can passed for concrete tubular pile at the infall of groined type concrete grating, wherein in concrete tubular pile and police schools, be equipped with cage of reinforcement.The present invention utilizes the groined type concrete grating singly connecing 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, decrease the lateral deformation of non-prestressed reinforcement structure, decrease concrete and the amount of reinforcement of Equivalent Support effect concrete tubular pile, speed of application is fast, saves engineering 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
All extensively adopt concrete perfusion pile tube campshed as supporting and protection structure at present when soft base and deep foundation ditch operation; namely concrete tubular pile adopts the mode be set up in parallel; to form a region of carrying out protecting with concrete tubular pile in operation area, cave in prevent the earth of operation area periphery.Then adopt when deep foundation ditch the structure of arranging in pairs or groups with prestressed anchor to carry out pattern foundation pit supporting structure, be provided with screw thread in the outer end of anchor pole, anchor pole is inserted in the soil body, and the outer end of anchor pole cover on channel-section steel, with nut, channel-section steel is fixed, to be fixed substantially cheating wall.But increase or the increase of foundation depth along with soft base distortion strength, then must increase the diameter of concrete tubular pile to play more firm effect, concrete diameter will corresponding increase reinforcing bar and concrete consumption after increasing, also engineering quantity can be increased simultaneously, so just engineering cost will certainly be increased, simultaneously anchor pole then will increase difficulty of construction running into when there is hard hard object at rear, even have influence on the actual effect of anchor pole, and then affect workmanship.
Summary of the invention
In order to solve the deficiency of existing supporting and protection structure, the invention provides a kind of grid type pile for prestressed pipe supporting and protection structure, this supporting and protection structure not only can play effective support action, and can promote supporting effect, reduce reinforcing bar and concrete consumption simultaneously, save the duration.
The present invention is realized by following technical proposals: it is made up of concrete tubular pile and groined type concrete grating, the hole can passed for concrete tubular pile is provided with at the infall of groined type concrete grating, wherein in concrete tubular pile and groined type concrete grating, be equipped with cage of reinforcement, and groined type concrete grating is integral one-step molding structure.Utilize the groined type concrete grating 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 supporting effect be promoted, reduce reinforcing bar and concrete consumption simultaneously, save engineering-built cost, be convenient to promote the use of.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is perspective view of the present invention.
Fig. 2 is plan view from above of the present invention.
Code description in figure: 1 concrete tubular pile; 2 groined type concrete gratings; 3 preformed holes; 4 tie-beams.
Detailed description of the invention
As shown in Figure 1 and Figure 2, concrete tubular pile (1) is separately positioned on the default stake position place of construction area, then passed from the preformed hole (3) the groined type concrete grating (2) corresponding to it respectively by concrete tubular pile successively, groined type concrete grating is fixed by tie-beam (4) and connects into an entirety.After wherein any concrete tubular pile is subject to lateral pressure, its active force all can be passed in whole support system by groined type concrete grating, thus decomposed the pressure that single-unit pile for prestressed pipe bears, give full play to the prestressing effect of concrete tubular pile.In practice, for improving resistance to tension of the present invention, cage of reinforcement is equipped with in concrete tubular pile and groined type concrete grating, and groined type concrete grating is integral one-step molding structure, simultaneously along with the increase of the foundation depth of its supporting, the reinforcing bar amount in concrete tubular pile and groined type concrete grating is also more.
Claims (2)
1. a grid type pile for prestressed pipe supporting and protection structure, include concrete tubular pile, it is characterized in that: be connected with groined type concrete grating on the top of concrete tubular pile, cage of reinforcement is provided with in concrete tubular pile, cage of reinforcement is provided with in groined type concrete grating, groined type concrete grating is fixed by tie-beam and connects into an entirety, and the infall of groined type concrete grating is provided with the hole can passed for concrete tubular pile, and groined type concrete grating is integral one-step molding structure.
2. a kind of grid type pile for prestressed pipe supporting and protection structure according to claim 1, is characterized in that: be provided with the fixing hole that can pass for concrete tubular pile at the infall of groined type concrete grating.
