Abstract
The utility model discloses a high-intensity direct picking and excavating foundation, which has the characteristics of an enlarging head such as high intensity and small size. The high-intensity direct picking and excavating foundation comprises a base pillar which is internally provided with steel bars, the bottom end of the base pillar is connected with the enlarging head which is internally and evenly provided with reinforcing ribs, the reinforcing ribs are connected with connecting ribs, the connecting ribs are connected with hoop ribs in the base pillars, and the base pillars, the enlarging head and the steel bars are poured into an integrated structure through concrete. As the shapes of reinforcing frames formed by the reinforcing ribs in the enlarging head are matched with the shape of the enlarging head, and the enlarging head is wholly made from the reinforced concrete, the foundation obviously improves the intensity of the enlarging head, correspondingly reduces the size of a foundation pit since the size of the enlarging head which is provided with the reinforcing ribs is smaller than that of the common enlarging head which is not provided with the reinforcing ribs under the condition that the intensity requirement is the same, and correspondingly reduces the use amount of the concrete, thereby not only being good for the environment protection, but also being capable of reducing the engineering cost.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
By shown in Figure 1, high tetanic digging foundation, comprise that internal configurations has the pilum 4 of the right circular cylinder shape of many stirrups 2 and vertical muscle 1, described pilum 4 bottoms are connected with enlarged footing 8, described enlarged footing 8 comprises the enlarged footing top 8A of truncated conical shape and the enlarged footing bottom 8B of right circular cylinder shape, the top of described enlarged footing top 8A and described pilum 4 are adaptive and be connected, the bottom of enlarged footing top 8A is adaptive with enlarged footing bottom 8B and be connected, the cross-sectional diameter of above-mentioned enlarged footing bottom 8B is greater than the cross-sectional diameter of pilum 4, described enlarged footing 8 inner edges circumferentially are evenly equipped with reinforcing rib 5, by shown in Figure 3, described every reinforcing rib 5 comprises the first vertical 5A of portion successively, the oblique 5B of portion, the second vertical 5C of portion, the transverse part 5D and the first hook portion 5E, by Fig. 1 and shown in Figure 3, the described first vertical 5A of portion be positioned at described pilum 4 inner and with the axially parallel of pilum 4, the described oblique 5B of portion is positioned at the inside of described enlarged footing top 8A and parallel with the bus of enlarged footing top 8A, the described second vertical 5C of portion be positioned at enlarged footing bottom 8B inside and with the axially parallel of enlarged footing bottom 8B, described transverse part 5D is positioned at the inside of enlarged footing bottom 8B and parallel with the bottom surface of enlarged footing bottom 8B, the length of above-mentioned transverse part 5D is less than the bottom surface radius of enlarged footing bottom 8B, and the described first hook portion 5E is positioned at enlarged footing 8 inside and forms hook shape with above-mentioned transverse part 5D; By illustrated in figures 1 and 2, above-mentioned every reinforcing rib 5 disposes a dowel 3, described dowel 3 comprises two sections, with a section of the axially parallel of above-mentioned pilum 4 be the 3rd vertical 3A of portion, another section is the second hook portion 3B and itself and the described the 3rd vertical 3A of portion formation hook shape, extremely shown in Figure 4 by Fig. 1, the described second hook portion 3B is connected with the above-mentioned oblique 5B of portion, the lower end of the above-mentioned the 3rd vertical 3A of portion is connected with the first hook portion 5E with the above-mentioned first vertical 5A of portion respectively, the bottom of above-mentioned dowel 3 is connected with above-mentioned transverse part 5D, and the part that the above-mentioned the 3rd vertical 3A of portion is positioned at pilum 4 is connected with the stirrup of pilum 4 inside; Above-mentioned pilum, enlarged footing, stirrup, vertical muscle, reinforcing rib and dowel are into a single integrated structure by concrete pouring.
The above reinforcing rib 5 and dowel 3 all by reinforcing bar by being bent into.In addition, the above-described second hook portion 3B is connected with the oblique 5B of portion, the lower end of the 3rd vertical 3A of portion is connected with the first hook portion 5E with the first vertical 5A of portion respectively and the bottom of the 3rd vertical 3A of portion is connected with transverse part 5D, and above connected mode can be welding also available iron wire binding connection or other connected mode.In addition, the bottom of above-mentioned dowel 3 is meant the bending place of dowel 3, promptly the 3rd indulges the position that the 3A of portion is connected with the second hook portion 3B.
Adopt said structure, every reinforcing rib 5 is connected with a dowel 3 on the one hand, conveniently reinforcing rib is placed foundation ditch inside when making construction, in addition, dowel 3 is connected with stirrup, the fixed-site of dowel 3 can be able to be made the fixed-site of reinforcing rib 5 in foundation ditch again; On the other hand, dowel 3 is joined together to form a face frame of being made up of reinforcing bar with reinforcing rib 5, makes reinforcing rib 5 be difficult for because of the external force effect deformation taking place.In addition, because the integral body of enlarged footing 8 is made of steel concrete, and all reinforcing ribs in the enlarged footing 8 form a reinforced frame, and the in-profile of this reinforced frame and enlarged footing 8 is complementary, and makes the intensity of enlarged footing 8 significantly improve.In identical geographical environment, support under the situation of identical electric power pylon, the size that disposes the enlarged footing 8 of reinforcing rib is less than the size of the common enlarged footing that does not dispose reinforcing rib obviously, this is because compare with the enlarged footing 8 that disposes reinforcing rib, the intensity that common enlarged footing will reach instructions for use just must increase concrete consumption, and the increase of concrete amount can cause the corresponding increase of enlarged footing size.Because it is less to dispose the size of enlarged footing 8 of reinforcing rib, corresponding the reducing of foundation ditch size that is dug in the time of can making construction, then the corresponding minimizing of native stone amount of being dug out during excavation pit reduces the environment damage degree, helps to protect environment.In addition, though the configuration reinforcing rib can cause amount of reinforcement to increase in the enlarged footing 8, because reducing of enlarged footing size makes concrete amount reduce, the native stone amount that excavation of foundation pit dug out in addition reduces, and makes whole engineering cost reduce.
