Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction. More specifically, the utility model relates to an auxiliary device for burying pipelines in soft soil areas. Background Art

[0002] Problems such as difficult drainage and ground settlement often occur in soft soil areas. The method of trench burying pipelines can appropriately solve this problem and maintain the stability of the ground through drainage. Due to the compression characteristics and bearing capacity of soft soil, traditional pipeline burying is prone to pipeline damage or settlement problems. In addition, there are strict slope requirements for pipeline burying, and traditional pipeline burying is not applicable to soft soil areas. Flat slopes or inverted slopes will cause the pipelines to be unable to drain. The Chinese invention patent with the application number 202111057471.2 discloses a trench burying pipe structure and construction method in soft soil areas. It buries pipes through the methods of trenching, enclosing, arranging internal support beams, hoisting pipelines, stabilizing pipelines, and filling around the pipes. The problems are that the construction process requirements are high, the construction requirements for mechanical facilities are high, and the pipelines are placed separately in the trench, and the pipeline slope is fixed by wrapping with all cement mortar. There are still problems of inconvenient adjustment of pipeline installation in soft soil areas and the risk of gravity settlement. This application urgently needs to solve the above technical problems. Summary of the Invention

[0005] A main trough body, having a detachable cover plate at its top and a conical part that can be inserted into the soft soil area at its outer bottom;

[0006] At least a pair of positioning rods, symmetrically and vertically arranged in the main trough body, the positioning rods being threaded and screwed with positioning nuts;

[0007] A bearing platform, which is a box-shaped structure, the top of the bearing platform is provided with an arc-shaped supporting surface, and both sides of the bearing platform are provided with ear plates, and the ear plates are detachably connected to the positioning nuts;

[0008] A pair of grouting pipes, symmetrically and horizontally arranged in the main trough body, the grouting pipes being provided with grouting holes facing between the bearing platform and the inner bottom of the main trough body;

[0009] A grouting ring pipe, embedded in the side wall and bottom of the main trough body, the grouting ring pipe being provided with grouting holes facing the soft soil area outside the main trough body.

[0010] Preferably, it further includes:

[0011] At least a pair of lateral tightening structures, symmetrically arranged inside the main trough body. The lateral tightening structure includes a tightening block, a tightening side plate, two lateral tightening rods, and two lateral tightening nuts. The tightening block has a vertically penetrating threaded hole and two horizontally penetrating through holes. The tightening block is threadedly connected to the positioning rod. The two lateral tightening rods pass through the tightening block and are connected to the outer surface of the tightening side plate. The two lateral tightening nuts screw the two lateral tightening rods onto the tightening block. The inner surface of the tightening side plate is provided with an arc-shaped supporting surface.

[0012] Preferably, it further includes:

[0013] At least one upper tightening structure, arranged at the inner bottom of the cover plate. The upper tightening structure includes a tightening frame, a tightening top plate, an upper tightening rod, and an upper tightening nut. The tightening frame is of a U-shaped structure and is suspended and installed. The tightening frame has a vertically penetrating through hole. The upper tightening rod passes through the tightening frame and is connected to the outer surface of the tightening top plate. The upper tightening nut screws the upper tightening rod onto the tightening frame. The inner surface of the tightening top plate is provided with an arc-shaped supporting surface.

[0014] Preferably, the positioning nut has an axially penetrating threaded hole and a plurality of vertically penetrating through holes evenly distributed along the circumferential direction.

[0015] Preferably, a support block is provided between the bearing platform and the inner bottom of the main trough body.

[0016] Preferably, the grouting holes of the pipe section of the grouting ring pipe embedded in the side wall of the main trough body are inclined downward.

[0017] The utility model has at least the following beneficial effects:

[0018] First, by placing the main trough body in the trench, arranging a positioning structure inside the main trough body, using the bearing platform to support the pipeline, adjusting the pipeline height to achieve slope adjustment, grouting inside and outside the main trough body to fix the position of the bearing platform and improve the soil strength in the soft soil area, the utility model can improve the slope energy-saving height of pipeline installation and at the same time improve the stability of pipeline installation in the soft soil area. The structure is simple, highly practical, and safe and reliable to use.

[0019] Second, the inside of the main trough body has a pipeline segment installation space. The main trough body is of a U-shaped structure. The conical part facilitates inserting the main trough body into the soil. The number of positioning rods can be multiple pairs, which are arranged along the extension direction of the pipeline. Each pair of positioning rods is symmetrically arranged and vertically arranged. The positioning rods are used for threaded connection with the positioning nuts. By rotating the positioning nuts, the height of the positioning nuts is adjusted so that the ear plates of the bearing platform are placed on the positioning nuts, forming an inclination angle of the pipeline to meet the slope requirements. The positioning nuts and the ear plates can also be fixed in height by means of connecting pieces or direct welding. The arc-shaped supporting surface of the bearing platform matches the pipeline arc to prevent shaking. A pair of grouting pipes inject cement mortar into the inside of the main trough body to form a stable support for the bearing platform with adjusted height. The grouting ring pipe injects cement mortar into the soil outside the main trough body to fill and compact the soil outside the main trough body, reducing the influence of the compression characteristics and bearing capacity of the soft soil on the pipeline and further improving the accuracy of the pipeline slope.

[0020] Third, during construction, first survey the position and dig a trench, then place the utility model in the trench. Calculate the pipeline installation height according to the pipeline slope, adjust the height of a pair of positioning nuts, install the bearing platform, fix the ear plates of the bearing platform to the positioning nuts. After installation, use a pair of end plates to close the front and rear of the main trough body to form a basically closed structure, and start grouting. A pair of grouting pipes grout into the inside of the main trough body, and stop grouting when the height reaches the upper middle part of the bearing platform. Synchronously, the grouting ring pipe grouts outside the main trough body, hardens, reaches the technical requirements, and then remove a pair of end plates.

[0021] Fourth, in order to further improve the stability of the pipeline, that is, to avoid horizontal shaking of the pipeline, by setting a side tightening structure, it tightens from the opposite side of the pipeline. The tightening block passes through the positioning rod and is threadedly connected thereto to realize the height positioning of the tightening block in cooperation with the pipeline. Two through holes of the tightening block respectively penetrate two side tightening rods. One end of the side tightening rod passes through the tightening block and is connected to the tightening side plate, which can be detachably connected by a connecting piece or welded after being installed in place. At the same time, the other end of the side tightening rod is tightened by a side tightening nut to realize the horizontal positioning of the side tightening rod in cooperation with the tightening block, ensuring that the pipeline does not move.

[0022] Fifth, in order to further improve the stability of the pipeline, that is, to avoid vertical shaking of the pipeline, by setting an upper tightening structure, it tightens from the top of the pipeline. The tightening frame is a portal frame, which is suspended and installed on the cover plate. The through hole of the tightening frame penetrates the upper tightening rod. One end of the upper tightening rod passes through the through hole of the tightening frame and is connected to the tightening top plate, which can be detachably connected by a connecting piece or welded after being installed in place. At the same time, the other end of the upper tightening rod is tightened by an upper tightening nut to realize the vertical positioning of the upper tightening rod in cooperation with the tightening frame, ensuring that the pipeline does not move.

[0023] Sixthly, design the positioning nut into a structure with a threaded hole in the middle and an axially through hole, which is convenient for the threaded connection between the positioning nut and the positioning rod to adjust the height, and is also convenient for the connection between the positioning nut and the ear plate of the bearing platform to fix the height of the bearing platform. Before grouting after the pipeline is installed, support blocks can be used to support the bearing platform from below, and steel bars or steel pipe piles can be used to improve the strength. Design the side grouting holes of the grouting ring pipe to be inclined downward to accelerate the spraying of the cement mortar at a certain angle.
