Abstract
Description
Technical Field
[0001] This utility model relates to the field of temporary sealing technology for dewatering wells, specifically a temporary sealing device for dewatering wells and pipeline fixing. Background Technology
[0002] In the construction industry, effective control of groundwater levels is crucial as various construction projects continue to advance. Dewatering wells, as a common facility for lowering groundwater levels and ensuring dry construction areas, are widely used in numerous projects. Through pumps and other equipment within the dewatering wells, groundwater can be extracted and discharged, preventing adverse effects such as foundation pit collapse and soil softening from occurring during construction, thus ensuring the smooth progress of the project.
[0003] However, there are some pressing problems in the actual use of dewatering wells. Firstly, the drainage pipes and pneumatic pipes used for drainage lack a reasonable and orderly arrangement outside the wells. These pipes are scattered haphazardly, making the construction site chaotic, greatly affecting the normal passage of personnel and vehicles, reducing the efficiency of the construction site, and increasing the risk of people tripping or vehicles running over and damaging the pipes. Once the pipes are damaged, it will lead to poor drainage and the inability of pneumatic equipment to operate normally, thus affecting the dewatering effect and delaying the construction progress. Secondly, dewatering wells need to be temporarily sealed during construction breaks or specific stages. If they are not effectively sealed, debris from the construction site can easily fall into the wells, causing blockages and affecting subsequent dewatering functions. Furthermore, there is a risk of serious safety accidents due to personnel accidentally falling into the wells, threatening the lives of construction workers. Utility Model Content
[0004] The present invention aims to solve the above problems and thus provide a temporary sealing device for dewatering wells and pipeline fixing device.
[0005] The technical solution adopted by this utility model to solve the aforementioned problem is:
[0006] A temporary sealing and pipeline fixing device for dewatering wells includes a dewatering well, a dewatering well cover plate installed above the wellhead, the dewatering well cover plate including a side plate surrounding the periphery of the dewatering well and a top cover plate, one side of the opposite sides of the top cover plate is hinged to the side plate, and the other side is connected to the side plate by a lock head, a pipe penetration notch is opened on one edge of the top cover plate, and a binding rope is fixedly connected to the side plate near the pipe penetration notch; a pipeline support rod for supporting and fixing the pipeline is provided on one side of the dewatering well cover plate, the pipeline support rod is located on the side of the dewatering well cover plate near the pipe penetration notch.
[0007] Furthermore, a fixing steel plate is installed at the bottom of the pipeline support rod, and the fixing steel plate is fixedly connected to the ground; this enhances the stability of the pipeline support rod.
[0008] Furthermore, a pipeline guide rod is installed above the dewatering well and between the frame columns on both sides. The middle part of the pipeline guide rod is fixedly connected to the pipeline support rod, and the two ends of the pipeline guide rod are fixedly connected to the adjacent frame columns respectively, providing clear guidance for the pipeline.
[0009] Furthermore, the surface of the dewatering well cover is provided with reflective strips, which include various colors and are arranged alternately. In low-light environments, such as nighttime construction or underground construction areas, the reflective strips can attract the attention of construction workers by reflecting light, thus serving as a warning to the construction workers on site.
[0010] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:
[0011] This utility model features a dewatering well cover plate installed above the wellhead. The side plates and top cover plate combine to form a closed structure. The top cover plate is hinged on one side and locked on the other, allowing construction personnel to quickly open the cover plate for operation when needed, while also ensuring a tight seal when not in use. This effectively prevents debris from falling into the well and avoids blockages that could affect subsequent dewatering. It also prevents personnel from accidentally falling into the well, ensuring their safety. Furthermore, the pipe penetration notch on the edge of the top cover plate provides a dual function of sealing the cover plate and allowing pipelines to pass through, without affecting the normal operation of the dewatering well. Drainage operations: By installing pipeline support rods on one side of the dewatering well cover, stable support points are provided for drainage pipes and pneumatic pipes, changing the previous situation of pipelines being scattered randomly, making the pipes arranged in an orderly manner, reducing the risk of people tripping over the pipelines when passing by, and reducing the risk of pipeline damage caused by vehicles running over the pipelines, ensuring the normal operation of the drainage system, and thus ensuring the continuity and stability of dewatering work; the binding ropes installed on the side plate near the pipe penetration opening further assist in fixing the pipelines, enhancing the stability of the pipeline layout, so that the entire device can play a good role in practicality and safety during construction.
