Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

Referring to fig. 1-4, a steel pipe pile foundation includes a steel pipe pile 1, a fixing plate 2 is fixedly connected to an upper surface of the steel pipe pile 1, the steel pipe pile 1 is connected to the fixing plate 2 through bolts, and after a protective guard is damaged, workers can replace the protective guard conveniently, so that the phenomenon that the steel pipe pile 1 needs to be dug out or replaced by a new position, which is more inconvenient, is avoided.

Threaded hole 3 is seted up in the four corners of fixed plate 2, and the lateral wall fixedly connected with rotating vane 4 of steel-pipe pile 1, rotating vane 4 adopt the revolution mechanic of earth anchor, are convenient for get into earth with rotating vane 4 is rotatory inside, improve fixed effect between rotating vane 4 and the earth simultaneously.

A plurality of rectangle recesses 5 have been seted up to steel-pipe pile 1's lateral wall symmetry, and rectangle recess 5 runs through the setting of steel-pipe pile 1 lateral wall, and rectangle recess 5's bottom surface fixedly connected with stopper 7, and one side of stopper 7 sets up to the arc surface, opens the card at fixture block 6 and fixed block 8 and advances earth after, and stopper 7 is spacing to fixture block 6, has avoided fixture block 6 and fixed block 8 to open the back completely, influences fixed effect.

The inside wall of rectangular groove 5 rotates and is connected with pivot 9, and the inside of rectangular groove 5 is inlayed and is equipped with the bearing, and the pivot is inserted and is established the inside rotation setting of bearing, reduces pivoted frictional force between fixture block and the rectangular groove, avoids fixture block and fixed block to receive earth extrusion back, because of the rotation frictional force between fixture block and the rectangular groove is too big, causes the unable open phenomenon of fixture block.

The lateral wall fixedly connected with fixture block 6 of pivot 9, the one end fixedly connected with fixed block 8 of fixture block 6, fixed block 8 extends the lateral wall of steel-pipe pile 1.

The working principle is as follows: when a worker installs the steel pipe pile 1, the steel pipe pile 1 is driven into the soil through a vibration hammer, the steel pipe pile 1 is driven into the position of the rotating blade 4, then the rotating blade 4 is rotated into the soil through the rotating steel pipe pile 1, so that the steel pipe pile is effectively fixed, meanwhile, the fixing block 8 at one end of the fixture block 6 is opened towards two sides and clamped into the soil under the action of the rotating steel pipe pile 1, so that the fixing effect between the steel pipe pile 1 and the soil is further increased, when the steel pipe pile 1 is pulled upwards by external force, the fixing block 8 at one end of the fixture block 6 is extruded by the soil, the fixture block 6 is continuously pulled towards two sides and clamped into the soil, the steel pipe pile 1 is stably inserted into the soil through the obstruction of the soil to the fixture block 6 and the fixing block 8, when the worker needs to replace the guard rail, the bolt between the guard and the steel pipe pile 1 can be removed, can change for the staff is simple and convenient more when changing the rail guard, has avoided needing to dig out steel-pipe pile 1, or has changed new position, causes phenomenons such as more inconvenient.
