Description

Technical Field

[0001] The utility model relates to the technical field of drainage for soft soil foundation treatment, in particular to a connecting member for vacuum preloading drainage plates of soft soil foundation. Background Art

[0002] In the prior art, the soft soil foundation is usually reinforced by the preloading drainage consolidation method. The preloading drainage consolidation method mainly includes two methods: vacuum preloading and surcharge preloading. When the soft soil foundation is reinforced by methods such as vacuum preloading or surcharge preloading, vertical sand wells or drainage plates are generally arranged in the soft soil foundation as drainage channels. Under the self-weight load of the surcharge material or the preloading of the vacuum load, drainage consolidation occurs, so that the pore water in the soft soil foundation is discharged outwards through the drainage channels.

[0003] In the prior art, for the installation of plastic drainage plates, a connecting member is required to splice the plastic drainage plates and the filter pipes. The traditional connecting member is difficult to use and inconvenient to operate. It is very difficult to firmly splice and fix the plastic drainage plates and the filter pipes, and it is easy to cause water leakage, resulting in poor use effect. Summary of the Utility Model

[0004] In order to solve the problems of the above prior art, the utility model provides a connecting member for vacuum preloading drainage plates of soft soil foundation, which solves the problems that the traditional connecting member is not firm in splicing the drainage plates and the filter pipes and is easy to leak water during use.

[0005] To achieve the above object, the utility model provides the following technical solution: A connecting member for vacuum preloading drainage plates of soft soil foundation, comprising a connecting cylinder, two mounting joints are symmetrically installed on the side wall of the connecting cylinder, a plurality of claw pieces are fixedly connected equidistantly along the circumference at the mouth of the connecting cylinder, external threads are arranged on the outer side surfaces of the claw pieces, and a fixing cover is connected to the claw pieces by threads.

[0006] With the above structural design, the drainage plates and the filter pipes are firmly connected by the connecting member to form a complete water conveyance system, avoiding the phenomena of water leakage or the drainage plates and the filter pipes slipping out of the connecting member, and improving the working efficiency and use effect.

[0007] Preferably, a clamping plate is fixedly connected to the interface of the mounting joint. The clamping plate includes an upper clamping piece and a lower clamping piece. A connecting ear is fixedly connected to the side wall of the clamping plate. A fixing bolt passes through the upper and lower connecting ears, and a knob is fixedly connected to the upper end of the fixing bolt.

[0008] With the above structural design, by rotating the knob, the upper clamping piece and the lower clamping piece approach each other, and the drainage plate is clamped by the pressure of the upper clamping piece and the lower clamping piece pressing against each other, making the connection between the drainage plate and the connecting member closer, preventing the drainage plate from slipping out of the mounting joint, increasing the connection tightness, and improving the drainage effect.

[0009] Preferably, grooves for increasing friction are equidistantly formed on the outer side wall of the fixed cover.

[0010] With the above structural design, by providing grooves, the friction for rotating the fixed cover is increased, facilitating the installation of the fixed cover.

[0011] Preferably, bumps are evenly distributed at equal intervals on the inner side wall of the clamping plate.

[0012] With the above structural design, the bumps are provided to increase the friction between the clamping plate and the drainage plate, preventing the drainage plate from disengaging from the installation joint.

[0013] Preferably, the thickness of the claw piece on the side close to the connecting cylinder is greater than the thickness on the side away from the connecting cylinder.

[0014] With the above structural design, the filter water pipe passes through the fixed cover and the claw piece and is inserted into the connecting cylinder. Through the threaded connection between the fixed cover and the claw piece, during the process of increasing the contact area between the fixed cover and the claw piece, the claw piece will be gradually pressed against the filter water pipe under the restriction of the fixed cover, increasing the friction between the claw piece and the filter water pipe, ensuring the stability and tightness of the connection between the connecting cylinder and the filter water pipe.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By rotating the knob, the upper clamping piece and the lower clamping piece approach each other, and the drainage plate is clamped by the pressure of the upper clamping piece and the lower clamping piece pressing against each other, making the connection between the drainage plate and the connecting member tighter, preventing the drainage plate from disengaging from the installation joint, increasing the connection tightness, and improving the drainage effect.

[0017] 2. The filter water pipe passes through the fixed cover and the claw piece and is inserted into the connecting cylinder. Through the threaded connection between the fixed cover and the claw piece, during the process of increasing the contact area between the fixed cover and the claw piece, the claw piece will be gradually pressed against the filter water pipe under the restriction of the fixed cover, increasing the friction between the claw piece and the filter water pipe, ensuring the stability and tightness of the connection between the connecting cylinder and the filter water pipe.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a connecting member for vacuum preloading drainage plates in soft soil foundations, including a connecting cylinder 1. Two mounting joints 2 are symmetrically installed on the side wall of the connecting cylinder 1. A plurality of claw pieces 4 are fixedly connected equidistantly along the circumference at the mouth of the connecting cylinder 1. An external thread 5 is arranged on the outer side surface of the claw piece 4. A fixing cover 3 is connected to the claw piece 4 by a thread. The drainage plate 11 and the filter pipe 10 are firmly connected through the connecting member to form a complete water conveyance system, avoiding the phenomena of water leakage or the drainage plate 11 and the filter pipe 10 slipping out of the connecting member, and improving the working efficiency and use effect.

[0023] A clamping plate 12 is fixedly connected to the interface of the mounting joint 2. The clamping plate 12 includes an upper clamping piece and a lower clamping piece. A connecting ear 7 is fixedly connected to the side wall of the clamping plate 12. A fixing bolt 9 passes through the two connecting ears 7 from top to bottom. A knob 8 is fixedly connected to the upper end of the fixing bolt 9. The drainage plate 11 is clamped by the pressure of the upper clamping piece and the lower clamping piece pressing against each other, making the connection between the drainage plate 11 and the connecting member tighter, preventing the drainage plate 11 from slipping out of the mounting joint 2, increasing the connection tightness, and improving the drainage effect.

[0024] Grooves 13 for increasing friction are equidistantly opened on the outer side wall of the fixing cover 3. By providing the grooves 13, the friction for rotating the fixing cover 3 is increased, facilitating the installation of the fixing cover 3.

[0025] Convex points 14 are evenly distributed at equal intervals on the inner side wall of the clamping plate 12. The convex points are provided to increase the friction between the clamping plate 12 and the drainage plate 11, preventing the drainage plate 11 from slipping out of the mounting joint 2.

[0026] The thickness of the claw piece 4 on the side close to the connecting cylinder 1 is greater than the thickness on the side far from the connecting cylinder 1. The filter pipe 10 passes through the fixing cover 3 and the claw piece 4 and is inserted into the connecting cylinder 1. Through the threaded connection between the fixing cover 3 and the claw piece 4, during the process of increasing the contact area between the fixing cover 3 and the claw piece 4, the claw piece 4 will be gradually pressed against the filter pipe 10 under the restriction of the fixing cover 3, increasing the friction between the claw piece 4 and the filter pipe 10, and ensuring the stability and tightness of the connection between the connecting cylinder 1 and the filter pipe 10.

[0027] Working principle: The construction workers pass the filter pipe 10 through the fixed cover 3 and the claw pieces 4 in sequence and extend it into the connecting cylinder 1. The fixed cover 3 is threadedly connected to the claw pieces 4. During the process of increasing the contact area between the fixed cover 3 and the claw pieces 4, the claw pieces 4 will gradually press tightly against the filter pipe 10 under the restriction of the fixed cover 3, increasing the friction between the claw pieces 4 and the filter pipe 10, and ensuring the stability and tightness of the connection between the connecting cylinder 1 and the filter pipe 10. The construction workers extend the drainage board 11 into the installation joint 2, rotate the knob 8 to make the upper clip and the lower clip approach each other, and clamp the drainage board 11 by the pressure of the upper clip and the lower clip approaching each other, making the connection between the drainage board 11 and the connecting member closer, preventing the drainage board 11 from disengaging from the installation joint 2, increasing the connection tightness, and improving the drainage effect.
