Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline connection, in particular to a pipeline connection device based on soft foundation reinforcement by vacuum preloading method. BACKGROUND

[0002] As a high-efficiency and practical foundation treatment technology in the field of soft foundation reinforcement, the vacuum preloading method is widely used in port construction, low-lying area improvement and foundation reinforcement engineering in river beach areas. Through this method, the drainage speed of pore water in the foundation can be significantly accelerated, thereby effectively improving the bearing capacity and stability of the foundation. In the construction process, the vacuum preloading method requires laying a layer of sand cushion as the foundation first, then burying one end of the drainage plate bag under the sand cushion, and connecting the other end to the main pipeline system through a special pipe plate connector. With the suction effect of the vacuum pump, negative pressure is generated to achieve the reinforcement effect of the foundation. However, in the actual construction process, a large number of drainage plate bags need to be arranged, which greatly increases the workload of manual docking, and often requires frequent bending or squatting to assist operation, greatly increasing the workload of construction personnel. At the same time, the drainage plate bag is usually in the shape of a flat rectangular cuboid, which makes the docking process more complex and tedious. More importantly, after the docking is completed, additional sealing and reinforcement treatment of the connection is required, which undoubtedly further prolongs the construction time, reduces the construction efficiency and overall operation speed.

The connection assembly quickly completes the connection of the drainage mechanism and the plug-in mechanism when taking the drainage mechanism, without the need for workers to frequently bend over to take the docking, greatly reducing the physical load of workers and improving work speed and efficiency.
