Abstract
The invention discloses an anomalous concrete tubular pile comprising a centre bore coaxially arranged with the pile shaft and end boards arranged at the two ends of the pile shaft, which is characterized in that the pile shaft positioned between the end boards is coaxially provided with a groove, and the transect of the groove is in semicircular shape, V-shape or U-shape, which are symmetrically or equally arranged around the pile shaft. The anomalous concrete tubular pile not only can be used for semi-rigid pile-soil composite foundation but also can be driven into soil as rigid pile; the tubular pile has the advantages of large superficial area, strong bearing capacity, and small use amount of concrete, and is particularly suitable for the geology of coastal areas and the Yellow River flood plain areas.
Description
Technical field:
The present invention relates to the pile foundation Foundation Design technology in the building field, be specifically related to prestressed concrete abnormity pile tube.
Background technology:
Prestressed high-strength concrete pile is widely used in the engineering constructions such as house, road, bridge with its superior performance.It mainly acts on is to be squeezed on the harder rock stratum, the end, ground by machinery to nail is the same, can better play the weight of buildings such as supporting house, bridge.For the coastal area or yellow general Plain, build about 12 layers little high residential building, generally all adopt rigid pile, and less expensive reasonably is semi-rigid compound base (saving the ground cost), is about to cement and is the clay shape with soil by mechanical agitation, then column or tube is inserted wherein, when treating its half curdled appearance, column or tube are extracted, fluid concrete in the hole is condensed into one with it more again; Or column or tubular coagulation soil member (comprise pile tube, down with) inserted wherein, be condensed into one with it.The first prefabricated fluid concrete in the hole then that portals, after a kind of mode easily cause to collapse the hole or form constriction and influence foundation quality, and after adopting a kind of mode to prepare semi-rigid compound base cost higher.Because the particularity of coastal area or yellow general Plain geological conditions, the bearing capacity of pile tube or the concrete component that inserts in the clay shape cement-soil are based on frictional force, and pile tube or " member " and soil contact face on every side are long-pending big more, and then bearing capacity is big more.According to this utility theory, when not increasing or reducing concrete amount, increase the surface area that inserts member in the semi-rigid compound base, to obtain ground, become pursuing one's goal of coastal area or yellow general Plain than large bearing capacity.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of special-shaped concrete pipe, and the pile tube surface area is big, and bearing capacity is strong, and concrete amount is few, is particularly suitable for the semi-rigid compound base in coastal area and uses.
The present invention is achieved through the following technical solutions:
A kind of special-shaped concrete pipe comprises and the centre bore of the coaxial setting of pile body that characteristics are coaxial grooves that are provided with on the pile body.
The further improvement project of the present invention is, a kind of special-shaped concrete pipe, comprise centre bore with the coaxial setting of pile body, be arranged at the end plate at pile body two ends, characteristics are coaxial grooves that are provided with on the pile body between the end plate, the shape invariance in cross section, pile crown two ends makes the termination bearing capacity identical with former stake, the construction of convenient stake.Pile tube in the technical program both can be used for semi-rigid compound base, also can be used as rigid pile and directly squeezed in the soil.
Pile body cross section among the present invention can be rectangle, circle or polygon (considering from the transportation angle, better with rectangle), the cross section semicircular in shape of groove, V-arrangement, U-shaped, and groove symmetry or five equilibrium are arranged at the side face of pile body.
The present invention has the following advantages:
One, the present invention has groove at the side face of pile body, makes that the girth of pile body is longer than the former stake of not establishing groove, has therefore increased the surface area of stake, that is has increased the frictional force of stake, and the corresponding bearing capacity that increases stake has reduced the concrete consumption simultaneously.Through to around respectively establish a groove barrette and former barrette area relatively, more than 25%, concrete amount reduces more than 30% the barrette that is provided with groove than the area increase of former barrette.
Two, at the coaxial grout hole that is provided with of centre bore one side of pile body, when bearing stratum is squeezed in stake, can adopt high-pressure slip-casting, reinforce the soil body of stake end, further improve the bearing capacity of stake.
Description of drawings:
Fig. 1 is arranged at the schematic perspective view on the pile body between the end plate for the groove among the present invention;
Fig. 2 is Figure 1A-A cross section enlarged diagram;
Fig. 3 passes through the schematic perspective view of pile body for the groove among the present invention.
The specific embodiment:
As shown in Figure 1, 2, a kind of special-shaped concrete pipe comprises the centre bore 2 with pile body 1 coaxial setting, is arranged at the end plate 3 at pile body 1 two ends.
Still as shown in Figure 1, 2, the coaxial groove 4 that is provided with on the pile body between the end plate 31.As shown in Figure 2, the pile body cross section is rectangular, the cross section semicircular in shape of described groove 4, and groove 4 is symmetricly set in pile body 1 peripheric surface.
As shown in Figure 1, 2, at the coaxial grout hole 5 that is provided with of centre bore 2 one sides of pile body 1.
Embodiment 2
As shown in Figure 3, a kind of special-shaped concrete pipe comprises the centre bore 2 with pile body 1 coaxial setting, the coaxial groove 4 that is provided with on pile body 1, and groove 4 is symmetricly set in pile body 1 peripheric surface.
All the other are implemented as embodiment 1.
