AI Technical Summary
During the construction of gravel piles, the pull-out rate and air pressure will affect the discharge speed, resulting in the crushed stone stuff being squeezed tightly in the pile pipe, making it difficult to get rid of the material, causing the construction to stop.
A jet pressurization device in the pile pipe of the gravel pile is designed. By installing eight sets of jet pressurization components on the pile pipe, the air pressure provided by the air compressor is used to maintain a certain air pressure in the pile pipe, promoting the discharge of the gravel, and increasing the instantaneous air pressure through the jet port when the discharge is abnormal to speed up the discharge speed.
It effectively accelerates the cutting speed of gravel materials, solves the construction stoppage caused by poor cutting, and ensures the continuity and efficiency of construction.

Abstract
Description
Technical Field
[0001] The utility model relates to an air jet pressurizing device in a pile pipe of a gravel pile ship. Background Art
[0002] Gravel piles are composite foundation reinforcement piles made of gravel (pebbles) as the main material. Gravel piles and pebble piles are collectively referred to as loose piles or coarse granular soil piles abroad. The so-called loose piles refer to piles without bonding strength. The composite foundation composed of loose piles such as gravel columns or pebble piles and soil between piles can also be called loose pile composite foundation. The composite foundations such as gravel piles, crushed stone piles, and slag piles widely used at home and abroad are all loose pile composite foundations.
[0003] During the construction of gravel piles, the pipe pulling rate and air pressure will affect the feeding speed of the gravel piles. Sometimes, the gravel is squeezed tightly in the pile pipe through the gap extrusion and is not easy to feed, resulting in the suspension of construction. Therefore, a jet pressurizing device in the pile pipe of a gravel pile ship is proposed to solve the above problems. Utility Model Content
[0004] The utility model aims to overcome the existing defects and provide a jet pressurizing device in the pile pipe of a gravel pile ship to accelerate the material feeding speed.
[0005] The technical scheme for achieving the above purpose is: a jet pressurizing device in a pile pipe of a gravel pile ship, comprising eight sets of jet pressurizing components, which are installed in two layers, with four sets evenly installed on the pile pipe in each layer.
[0006] Preferably, the jet pressurization assembly includes an air intake pipe, a jet support, a one-way air intake valve and a two-inch column tube bolt;
[0007] The jet support is connected to the air inlet pipe, the one-way air inlet valve is arranged inside the jet support, one end of the jet support is connected to the two-inch column tube bolt, and the other end is connected to the pile pipe.
[0008] Preferably, the jet support is connected to the pile pipe by welding.
[0009] Preferably, the upper end of the pile pipe is an airtight door; the lower end is crushed stone.
[0010] Preferably, the upper end of the air inlet pipe is connected to an air compressor.
[0011] Preferably, the angle between the air inlet pipe and the air jet support is 30°.
[0012] The beneficial effects of the utility model are as follows: the jet pressurizing device in the pile pipe of the gravel pile ship adds 4 jet pressurizing components on the upper and lower parts of the pile pipe of the gravel pile ship, so that the air in the air compressor enters the pile pipe through the air pipe, so that a certain air pressure is maintained in the pile pipe, so that the crushed stone material is discharged normally during the pipe pulling process. If the discharge is abnormal, the instantaneous air pressure can be increased through the jet port to speed up the discharge speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.
[0017] The utility model will be further described below in conjunction with the accompanying drawings.
[0018] like Figure 1-2 As shown, a jet pressurizing device in a pile pipe of a crushed stone pile ship mainly functions to balance and increase the air pressure in the pipe: it includes eight sets of jet pressurizing components 20, which are installed in two layers, four sets in each layer are evenly installed on the pile pipe 10. The upper end of the pile pipe 10 is an airtight door 30; the lower end is crushed stone 40.
[0019] Specifically, the jet pressurization assembly 20 includes an air intake pipe 201, an air intake support 202, a one-way air intake valve 203 and a two-inch column tube bolt 204; the air intake pipe 201 is connected to the air intake support 202, and the upper end of the air intake pipe 201 is connected to the air compressor. The angle between the air intake pipe 201 and the air intake support 202 is 30°. A one-way air intake valve 203 is arranged inside the air intake support 202, one end of the air intake support 202 is connected to the two-inch column tube bolt 204, and the other end is connected to the pile pipe 10. The air intake support 202 is welded to the pile pipe 10.
[0020] Specifically, during construction, the upper end of the pile pipe is sealed and pressure-maintained by an airtight door 30, and the interior below the pile pipe is filled with crushed stone 40, forming a relatively intact closed space.
[0021] When jet pressurization is needed, the air compressor is turned on, and the compressed air in the air compressor enters the jet support 202 through the air inlet pipe 201, and then enters the pile pipe 10 through the one-way air inlet valve 203. Since the pile pipe forms a sealed space up and down and has no other air outlet, the pressure in the pile pipe can be maintained.
[0022] If gravel is stuck in the pile pipe 10 and the gravel does not flow out when the pipe is pulled out, the jet pressurizing device can be opened to increase the instantaneous air pressure in the pile pipe so that the gravel can flow out normally and the gravel feeding rate can match the pipe pulling rate, thereby achieving the effect of controlling the pile quality.
[0023] The jet pressurizing device in the pile pipe of the gravel pile ship is provided with four jet pressurizing components 20 respectively on the upper and lower sides of the pile pipe 10 of the gravel pile ship, so that the air in the air compressor enters the pile pipe 10 through the air pipe, so that a certain air pressure is maintained in the pile pipe 10, so as to promote the normal discharge of gravel during the pipe pulling process. If the discharge is abnormal, the instantaneous air pressure can be increased through the jet port to speed up the discharge speed.
[0024] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
