Abstract
Description
Technical Field
[0001] The invention relates to the technical field of vacuum pre-pressing for reverse pumping, and in particular to a drainage wrench-type joint for reverse pumping. Background Art
[0002] With the continuous expansion of the scale of construction in my country's coastal areas, the supply of land resources is becoming increasingly tight, and reclamation of seashores has become the main way to obtain land resources. Seashore reclamation often adopts the method of land reclamation by blowing and filling, but the water content of the blown-fill silt is high, the fluidity is large, and the bearing capacity is extremely low. It usually needs to be reinforced by vacuum preloading before it can be used. Vertical drainage boards are generally used in traditional vacuum preloading drainage construction methods. Because the pumping end of the vertical drainage board is at the top, the vacuum degree decays along the depth direction of the vertical drainage board, which often leads to poor treatment of the underlying soil, and ultimately makes the overall reinforcement effect of the soil uneven.
[0003] In response to the problems existing in the current vacuum preloading technology, a patent (CN116043812A) has proposed a vacuum preloading system based on reverse pumping, which can solve the problem of vacuum attenuation along the depth direction of the vertical drain board in the traditional vertical drainage structure. However, the above method has the problem of difficulty in inserting the board during the actual construction process. The traditional positive drain board can bend a section of the drain board as a fulcrum when inserting the board, but the reverse pumping drain board has a pumping end at the bottom, and bending the drain board will hinder the upward transmission of the vacuum, so it is necessary to propose a drain board hand-type joint for reverse pumping.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] The purpose of the present invention is to provide a drain plate hand-type joint for reverse drainage, which solves the problem of reverse drain plate plugging.
[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] like Figures 1 to 8 As shown, this embodiment provides a drainage wrench-type joint for reverse pumping, including a concentric reducing tubular connecting end 1, an inclined reduced pipe diameter 7, a plug-in slot 2 and a board side slot 3; the upper part of the concentric reducing tubular connecting end 1 is used to connect with the vacuum tube 9; the lower part of the concentric reducing tubular connecting end 1 is connected to the top of the inclined reduced pipe diameter 7; the plug-in slot 2 is arranged between the board side slot 3 and one side of the inclined reduced pipe diameter 7.
[0032] In this specific embodiment, the concentric reducer tubular connection end 1 includes a plurality of tapered tubes connected in sequence; and the diameter of the smaller end of the tapered tube is larger than the diameter of the larger end of the adjacent tapered tube above. A cylindrical tube is provided on the top of the concentric reducer tubular connection end 1. By inserting the tapered tube of the concentric reducer tubular connection end 1 into the vacuum tube 9 and tying and connecting it through the vacuum tube binding wire 10, the diameter of the cylindrical tube of the concentric reducer tubular connection end 1 is 12mm, and each 10mm downward is a layer, and the diameter of each layer increases by 5mm. The diameter of the lower end is 32mm, which can be applied to five different diameters of steel wire hoses of 10mm, 15mm, 20mm, 25mm, and 30mm. The 1mm protruding outward of the tapered tube is used to fix the steel wire of the steel wire hose to prevent the steel wire from falling off.
[0033] The inclined reduced diameter pipe 7 is a cylindrical pipe, and a first inclined surface is arranged on the side of the inclined reduced diameter pipe 7 away from the plug-in slot 2. The first inclined surface can reduce the force bearing area between the hand-shaped joint and the soil, increase the pressure, and reduce the difficulty of plugging the board.
[0034] The bottom of the strip slot 2 and the board side slot 3 is provided with a tip 5, and the inclined surface of the tip 5 is located in the same plane as the first inclined surface of the inclined reduced diameter 7. The tip 5 can increase the pressure when manually inserting the board and reduce the difficulty of inserting the board.
[0035] An air hole 6 is provided between the inclined and reduced diameter tube 7 and the socket card slot 2, and the air hole 6 is used for transmitting vacuum and draining water.
[0036] Round holes 4 with a diameter of 4 mm are provided on both sides of the socket slot 2. A drain board 8 is provided in the socket slot 2. The drain board 8 is connected to the socket slot 2 by inserting a drain board binding wire 11 into the round hole 4 to prevent the drain board 8 from falling off.
[0037] A patch 13 is arranged in the board side slot 3, and the top of the patch 13 is connected to the bottom end of a steel pipe 12. The bottom of the board side slot 3 is sealed, which serves as a force point for the patch 13.
