(Summary description)At present, the leakage detection of municipal solid waste landfills mainly adopts the methods specified in relevant standards, including background wells, drainage wells, pollution diffusion wells and pollution monitoring wells. Since the groundwater level is lower than the anti-seepage structure layer of the landfill, groundwater has no adverse effect on the anti-seepage structure layer, so there is no need to set up drainage wells.

At present, the leakage detection of municipal solid waste landfills mainly adopts the methods specified in relevant standards, including background wells, drainage wells, pollution diffusion wells and pollution monitoring wells. Since the groundwater level is lower than the anti-seepage structure layer of the landfill, groundwater has no adverse effect on the anti-seepage structure layer, so there is no need to set up drainage wells. At this time, it is necessary to regularly sample and analyze the pollution diffusion wells and pollution monitoring wells around the landfill to understand the groundwater pollution. However, the existing leak detection structures for landfills still have some shortcomings in use. When in use, the drain pipe and the water pipe cover are usually connected by screw threads, and the water pipe cover cannot be opened and closed quickly, and it is not convenient to detect the extracted leachate or groundwater. When the drainage pipe in the drainage ditch is subjected to the external force of the additional load generated by the landfill, the uneven settlement of the foundation will damage the pipeline system and cannot buffer the force. In addition, the operation of sampling and monitoring leachate from the natural ground cannot be guaranteed. Therefore, we propose a leakage detection structure for municipal solid waste landfills.

In order to solve the problems of the above-mentioned system, technicians provide a leakage detection structure for municipal solid waste sanitation and urban solid waste landfill. It adopts the following technical solutions: including natural foundation layer, landfill, anti-seepage layer, drainage The anti-seepage layer is located in the gap between the landfill and the natural foundation layer, the drainage ditch is located at the bottom of the anti-seepage layer, and the drainage pipe is located in the drainage ditch. One end of the drain pipe is located outside the natural base layer. The top surface of the drain pipe is provided with a water pipe cover. The connection mechanism includes a plug passing through one side of the drain pipe. The connection between the drain pipe and the water pipe cover is provided with a torsion spring. There is a support plate, the gap between the support plate and the drain pipe is fixedly connected with a connecting column, the insertion column passes through the support plate, and the gap between the rubber sleeve and the support plate is connected with a spring sleeve, and the spring sleeve is located outside the insert.

Wherein, a pull ring is fixedly installed on one end surface of the plug, and the pull ring is located outside the drain pipe. A small hole is opened on one side of the drain pipe, and the insertion post passes through the small hole. There are two sets of connecting columns, and the two sets of connecting columns are symmetrically arranged on one side of the support plate. The specifications of the second connecting board are consistent with the specifications of the third connecting board, and the specifications of the first extension board are consistent with the specifications of the third extension board. The connection between the first connecting plate and the buffer tube is an I-shape, and the connection between the third connecting plate and the buffer tube is an I-shape. The specification of the first rubber column is consistent with the specification of the second rubber column, and the first rubber column and the second rubber column are symmetrically fixedly connected to one side surface of the second connecting plate.

Compared with the prior art, the leakage detection structure of the leakage landfill site has the following beneficial effects: 1. By setting the plug-in column, the use of threaded connection between the drain pipe and the water pipe cover is effectively avoided, and the water pipe cover cannot be opened quickly. It is easy to detect the extracted leachate or groundwater, and has better practicability; 2. By setting up a buffer pipe, it can effectively avoid the drainage pipe in the drainage ditch being affected by the additional load external force generated by the landfill due to uneven foundation. Settlement damages the pipeline system, which is beneficial to buffer the force, so as to ensure the sampling and monitoring of the leachate in the natural base layer, which is more stable and durable.
