Technical field

[0001] The utility model relates to the compressed air supply device in the pile tube of a gravel pile driving vessel. Background technology

[0002] A gravel pile is a pile used to reinforce composite foundations, consisting primarily of gravel (or pebbles). Gravel piles and pebble piles are commonly referred to as loose-fill piles or coarse-grain piles abroad. Loose-fill piles are piles without bond strength. A composite foundation composed of loose-fill piles, such as gravel columns or pebble piles, and the soil between the piles can also be referred to as loose-fill pile composite foundation. The composite foundations widely used at home and abroad, such as gravel piles and silt piles, all belong to the loose-fill pile composite foundation.

[0003] During the construction process of gravel piles, the pipe pulling speed and the magnitude of air pressure may affect the discharge speed of gravel piles, sometimes the gravel material will be greatly compressed due to the pressure caused by the gaps in the pile pipe, difficult to discharge, which will lead to the interruption of construction work, therefore, a compressed air supply device in the pile pipe of gravel pile driving ship is proposed to solve the above problem. Subject of the utility model

[0004] The purpose of the utility model is to provide a compressed air supply device in the pile pipe of a gravel pile driving vessel that overcomes existing deficiencies and increases the discharge speed.

[0006] Preferably, the compressed air supply component comprises an air inlet tube, an air outlet base, a check inlet valve, and a two-inch column tube bolt; The air inlet pipe is connected to the air outlet base, the check inlet valve is arranged inside the air outlet base, one side of the air outlet base is connected with the two-inch column pipe bolt, the other side is connected with the pile pipe.

[0007] Preferably, the air outlet base is welded to the pile tube.

[0008] Preferably, the upper end of the pile tube is provided with an airtight door; the gravel material is located underneath.

[0009] Preferably, the upper end of the air inlet pipe is connected to an air compressor.

[0010] Preferably, the angle between the air inlet pipe and the air outlet base is 30°.

[0011] The advantageous effect of this utility model is as follows: The compressed air supply device in the pile tube of the gravel pile driving ship, thereby four compressed air supply components are installed above and below the pile tube, so that the air from the air compressor is fed into the pile tube via the air inlet pipe, thereby maintaining a constant air pressure in the pile tube, which promotes normal discharge of the gravel material during the pipe pulling process, if the discharge is not smooth, the instantaneous air pressure can be increased through the air outlet port to increase the discharge speed. Designation of the drawings Fig. 1 is a schematic diagram of the application and connection of the compressed air supply device in the pile pipe of the gravel pile driving vessel of the utility model; Fig. 2 is a detailed view of the compressed air supply component of the utility model.

[0013] The technical solutions of the utility model are described clearly and completely below, taking into account the attached figures. It should be noted that in the description of the utility model, terms such as "center," "top," "bottom," "left," "right," "vertical," "horizontal," "inside," and "outside" describe directions or positional relationships that refer exclusively to the positions and orientations shown in the figures. These terms are merely intended to simplify the description of the utility model and are not intended to indicate or imply that the devices or components in question must necessarily have a particular orientation or be constructed or operated in a particular direction. Therefore, they should not be understood as limitations of the present utility model. Furthermore, the terms "first," "second," "third," etc., serve only to simplify the description of the utility model.merely description and should not be understood as an indication of a sequence or meaning.

[0014] The utility model is described in more detail below in conjunction with the attached figures.

[0015] As in the Fig. 1-2 shows a compressed air supply device in the pile tube of a gravel pile driving vessel, the main function of which is to equalize and increase the air pressure in the tube. It includes eight groups of compressed air supply components 20, with eight groups of compressed air supply components 20 installed at the upper and lower levels, and four groups at each level evenly installed on the pile tube 10. The upper end of the pile tube 10 is provided with an airtight door 30; below is the gravel material 40.

[0016] Specifically, the compressed air supply component 20 includes an air inlet pipe 201, an air outlet base 202, a check inlet valve 203, and a two-inch column tube bolt 204. The air inlet pipe 201 is connected to the air outlet base 202, and the upper end of the air inlet pipe 201 is connected to an air compressor. The angle between the air inlet pipe 201 and the air outlet base 202 is 30°. The check inlet valve 203 is arranged inside the air outlet base 202. One side of the air outlet base 202 is connected to the two-inch column tube bolt 204, and the other side is connected to the pile tube 10. The air outlet base 202 is welded to the pile tube 10.

[0017] Specifically, during construction, the upper end of the pile tube is closed by the airtight door 30 and kept under pressure, with the gravel material 40 located in the lower area of ​​the pile tube interior, so that a relatively well-sealed space is created.

[0018] When compressed air supply is required, the air compressor is switched on, and the compressed air from the air compressor enters the air outlet base 202 via the air inlet pipe 201 and then enters the pile tube 10 via the check inlet valve 203. Since the pile tube is sealed at the top and bottom and there are no other outlets, the pressure in the pile tube is maintained.

[0019] When gravel material is blocked in the pile tube 10 and the gravel material is not discharged when the tube is pulled out, the compressed air supply device can be turned on to increase the instantaneous air pressure in the pile tube, so that the gravel material is discharged normally, thereby harmonizing the discharge speed of the gravel material with the tube pulling speed, resulting in better control of the pile quality.

[0020] The compressed air supply device in the pile tube of the gravel pile driving ship, thereby four compressed air supply components 20 are installed above and below the pile tube 10, so that the air from the air compressor is fed into the pile tube 10 via the air inlet pipe, thereby maintaining a constant air pressure in the pile tube 10, which promotes normal discharge of the gravel material during the pipe pulling process, if the discharge does not proceed smoothly, the instantaneous air pressure can be increased through the air outlet opening in order to increase the discharge speed.
