Description

Technical Field

[0001] This utility model relates to the field of soft soil drainage technology, specifically a drainage and pressure relief structure for treating uneven deformation of roadbed in soft soil road sections. Background Technology

[0002] When uneven deformation occurs in the subgrade of soft soil sections, drainage measures are usually required to reduce pressure, which is one of the core technical means of soft soil treatment and deformation control.

[0003] In existing technologies, multiple drainage boards are typically inserted into the ground, with the tops of every two drainage boards connected to a connecting plate. This connecting plate has a through groove and a circular connecting block, with each connecting block connecting two pipes. During drainage operations, pressure is first applied to the deformed parts of the roadbed to press down the bulging sections. Under this pressure, water in the soft soil is transported upward through the drainage boards to the connecting pipes on the ground. However, during this water transport process, the connection between the connecting block and the connecting pipe is prone to instability, leading to a decrease in water transport efficiency or even leakage, which seriously affects the drainage and pressure reduction effect and results in poor overall practicality. Utility Model Content

[0004] The purpose of this utility model is to provide a drainage and pressure relief structure for treating uneven deformation of the roadbed in soft soil sections, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drainage and pressure-reducing structure for treating uneven deformation of roadbed in soft soil sections, comprising two drainage plates, a connecting plate slidably connected to the drainage plates, a through groove on the top wall of the connecting plate, a connecting block fixedly connected to the top of the connecting plate at the position corresponding to the through groove, and two connecting pipes slidably connected to the connecting block; Rubber rings are fixedly connected to the opposite ends of the connecting pipes. A quick-locking mechanism is provided on the connecting block. The quick-locking mechanism includes two threaded rings and multiple pressure rods. A rotating handle is fixedly connected to one end of each threaded ring.

[0006] Preferably, the integral plate communicates with the connecting block through a through groove.

[0007] Preferably, the threaded ring is symmetrically threaded inside the connecting block, and the rotating handle is located at the side end of the connecting block.

[0008] Preferably, the rubber rings are all slidably connected inside the connecting block, and the threaded rings abut against the corresponding rubber rings at the corresponding positions inside the connecting block.

[0009] Preferably, all the pressure rods are slidably connected to the connecting block and the connecting plate, and the top of each pressure rod is spherical.

[0010] Compared with the prior art, the beneficial effects of this utility model are: through the linkage and cooperation of the internal components of the quick-lock mechanism, the drainage plate and the connecting pipe can be reinforced and limited simultaneously, which greatly improves convenience. At the same time, the reinforcement structure can effectively enhance the connection stability between the drainage plate and the connecting pipe, fundamentally avoiding problems such as water leakage and poor water delivery caused by loose connection during water delivery, and ensuring stable and efficient drainage pressure reduction operation.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 The present invention provides the following technical solution: Example 1: A drainage and pressure relief structure for treating uneven deformation of roadbed in soft soil sections includes two drainage plates 1, with a connecting plate 2 slidably connected to the drainage plates 1. A through groove 3 is opened on the top wall of the connecting plate 2, and a connecting block 4 is fixedly connected to the top of the connecting plate 2 at the position corresponding to the through groove 3. Two connecting pipes 5 are slidably connected to the connecting block 4, and the connecting plate 2 communicates with the connecting block 4 through the through groove 3. In use, the drainage board 1 is driven into the roadbed that needs drainage by an external power device. Then, the connecting plate 2 is connected to the drainage board 1, and the connecting block 4 is connected to the connecting pipe 5. The external equipment applies pressure to the ground, causing the ground to settle. The pressure will cause the water from the ground to flow upward along the drainage board 1 and eventually flow into the interior of the connecting plate 2. Then, it enters the two connecting pipes 5 on the connecting block 4 through the through groove 3 and is discharged through the connecting pipes 5. Multiple sets of drainage boards 1 can be set up to drain and reduce pressure together.

[0015] Example 2: The technical solution that differs from Example 1 in this example includes: rubber rings 6 are fixedly connected to the opposite ends of the connecting pipe 5, and a quick-locking mechanism 7 is provided on the connecting block 4. The quick-locking mechanism 7 includes two threaded rings 71 and multiple pressure rods 72. A rotating handle 73 is fixedly connected to one end of each threaded ring 71. The threaded ring 71 is symmetrically threaded inside the connecting block 4. The rotating handle 73 is located at the side end of the connecting block 4. The rubber rings 6 are all slidably connected inside the connecting block 4. The threaded ring 71 abuts against the corresponding rubber ring 6 at the corresponding position inside the connecting block 4. The pressure rod 72 is slidably connected to the connecting block 4 and the connecting plate 2. The top of the pressure rod 72 is spherical. In use, the top of the drainage plate 1 is inserted into the connecting plate 2. At this time, the bottom of the pressure rod 72 will abut against the corresponding drainage plate 1. Then, when the connecting pipe 5 is connected to the connecting block 4, the connecting pipe 5 will drive the rubber ring 6 to connect to the inside of the connecting block 4. As the rubber ring 6 enters the connecting block 4, it will abut against the top of the pressure rod 72. As the rubber ring 6 goes deeper, it will deform and thus go beyond the pressure rod 72 and continue to go deeper into the connecting block 4. Then, the threaded ring 71 is screwed into the side of the connecting block 4. The rotating handle 73 drives the threaded ring 71 to rotate and slowly push it into the connecting block 4 through the thread. When the threaded ring 71 is connected to the connecting block 4, it will abut against the rubber ring 6. At the same time, as the threaded ring 71 pushes into the connecting block 4, it will also squeeze the spherical position at the top of the pressure rod 72. At this time, the pressure rod 72 will be forced to move down. The downward movement of the pressure rod 72 will squeeze and deform the drainage plate 1, thereby improving the connection between the drainage plate 1 and the connecting plate 2 and preventing it from falling off during operation.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
