Problems solved by technology
During conventional construction, when the immersed tube reaches the design elevation, the general cast-in-situ pile hopper is used for feeding, the feeding speed is uncontrollable, and the air pressure in the pile tube is likely to increase sharply during the feeding process, which is not conducive to the quality control of pouring
[0003] Therefore, there are above-mentioned inconveniences and problems in the known cast-in-situ pile hopper in the construction process of the static pressure sinking pile.

Embodiment 1
[0026] see now figure 1 , figure 1 It is a structural schematic diagram of the air-permeable controllable feeding hopper of the static pressure pipe sinking pile machine according to the embodiment of the present invention. As shown in the figure, the hopper body 1 of the hopper is a bucket-shaped device composed of a cylinder and a tapered bucket welded together. The upper mouth is large and the lower mouth is small. The upper mouth of the bucket body 1 is solidly welded, the length of the beam is the inner diameter of the bucket body cylinder, and the guide pipe 2 is vertically welded in the middle of the beam 1;
[0027] The load-bearing device is provided with a connecting piece 5, a load-bearing pipe 3 and a hopper door 7. The load-bearing pipe 3 is a hollow tube passing through the upper beam 6 of the bucket body 1, and its top is solidly welded with a steel wire rope and a static The connecting piece 5 connected to the crane of the sinking pipe pile machine, the circu...

The invention relates to a breathable controllable feed hopper of a static-pressure pipe pile sinking machine machine. The breathable controllable feed hopper comprises a hopper body (1), a bearing tube (3) and a plurality of cushion ribs (4). The breathable controllable feed hopper is characterized in that the hopper body (1) is a hopper-shaped device formed by welding a cylinder and a tapered hopper; the bearing device is provided with a connection (5), the bearing tube (3) and a feed hopper door (7); the cushion ribs (4) are uniformly distributed and fixedly welded to a strip-shaped gasket iron at the lower end of the tapered hopper of the hopper body (1) and serve as contact gaskets at an opening of a pile tube. The breathable controllable feed hopper is simple in structure, easy to produce, convenient, safe and reliable to produce, effective in decreasing air pressure in the tube during irrigation and reasonable in controlling irrigation speed.
Description
technical field [0001] The invention relates to a feeding hopper, in particular to a breathable and controllable feeding hopper of a static pressure pipe sinking pile machine. Background technique [0002] During the construction of the static pressure sinking pile, it is necessary to add the filler that meets the design into the sinking tube, and pull the sinking tube out of the ground according to the technological requirements to complete the construction of the sinking tube pile. During conventional construction, when the immersed tube reaches the design elevation, the general cast-in-situ pile hopper is used for feeding. The feeding speed is uncontrollable, and the air pressure in the pile tube is likely to increase sharply during the feeding process, which is not conducive to the quality control of pouring. [0003] Therefore known cast-in-situ pile hopper has above-mentioned various inconveniences and problems in the construction process of static pressure sinking pip...
