Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of drainage pipes, and in particular relates to a drainage pipe for a municipal construction project. Background Art
[0002] Municipal drainage pipes are generally divided into sewage and drainage pipes. Sewage is collected by drainage pipes and sent to sewage treatment plants before being discharged into nearby water bodies or recycled. Rainwater runoff is collected by drainage pipes and generally discharged into nearby water bodies, such as rivers and canals. Pipes are generally arranged in multiple lines and exposed near water bodies. The volume of drainage pipes varies depending on the amount of rainfall.
[0003] Inspection wells, commonly known as "manholes", are generally located at the intersection of drainage pipes, bends, changes in pipe diameter or slope, waterfalls, and at certain intervals on straight pipe sections. They are drainage ancillary structures that facilitate regular inspection, cleaning and unblocking of pipes.
[0004] At present, a Chinese patent with publication number CN219973443U and publication date November 7, 2023 discloses a municipal drainage pipe cleaning and collection device, including a first drain pipe and a second drain pipe, a square manhole is built between the first drain pipe and the second drain pipe, a square mesh tube is placed on the inner surface of the square manhole, and square openings are opened on the outer surfaces of both sides of the square mesh tube. An inclined guardrail is fixedly connected to the inner surface of the square mesh tube, and a material receiving assembly is placed in the square manhole, so that garbage during cleaning can be flushed into the square mesh tube for collection, which is convenient for collecting garbage during cleaning.
[0005] When small particles of impurities such as silt in sewage pass through the manhole, the silt cannot be filtered out by the mesh tube and the inclined guardrail, which will ultimately be detrimental to the filtration and collection of small particles of impurities such as silt. Utility Model Content
[0006] The utility model aims to provide a drainage pipe for a municipal construction project, which can better collect small particles of sediment in sewage.
[0007] The above-mentioned technical purpose of the utility model is achieved through the following technical scheme: a municipal construction engineering drainage pipe, comprising an inspection well, an inlet pipe located on one side of the inspection well, and an outlet pipe located on the other side of the inspection well, wherein a baffle extending in a vertical direction and located between the inlet pipe and the outlet pipe is arranged in the inspection well, a gap for sewage to pass through is left between the lower end of the baffle and the bottom wall of the inspection well, an overflow plate connected with the bottom wall of the inspection well at the lower end is arranged in the inspection well and located on the side of the baffle close to the outlet pipe, a filter basket located below the inlet pipe is detachably connected to the side of the baffle away from the overflow plate, vertical grooves for the side edges of the baffle to be embedded are provided on the inner walls on both sides of the inspection well, connecting rods are arranged on both sides of the lower end of the baffle, and a storage tray that abuts against the bottom wall of the inspection well and is used to store mud and sand is arranged between the lower ends of the two connecting rods.
[0008] The utility model is further configured as follows: dovetail slide grooves extending in the vertical direction are provided on both sides of the baffle plate, and dovetail slide rods embedded in the dovetail slide grooves are provided on both sides of the filter basket.
[0009] The utility model is further configured as follows: a drain port is provided on the storage tray, a connecting sleeve is provided around the drain port, a connecting column extending in a vertical downward direction is provided on the lower side of the filter basket, and a sealing plate covering the connecting sleeve is provided at the lower end of the connecting column.
[0010] The utility model is further configured as follows: a handle bar is arranged on the inner side of the filter basket.
[0011] The utility model is further configured as follows: a filter screen is provided on the inner wall of the inspection well and at the position of the water outlet pipe.
[0012] The utility model is further configured as follows: a handle groove is provided at the upper end of the baffle.
[0013] In summary, the utility model has the following beneficial effects:
[0014] 1. After the sewage from the water inlet pipe enters the inspection well, it will first fall into the filter basket, through which the large particles of impurities in the sewage can be filtered, so that the large particles of impurities are retained in the filter basket; the sewage after passing through the filter basket can pass through the gap at the lower end of the baffle plate and then flow into the overflow plate. At this time, the sewage first passes through the barrier of the baffle plate to reduce the flow rate of the sewage, so that the flow rate of the sewage is relatively stable after it is collected on one side of the overflow plate; and the sewage can settle at the overflow plate, so that the sediment is deposited on the receiving plate at the bottom of the inspection well under the action of its own gravity, and finally the small particles of sediment in the sewage can be better collected;
[0015] When the sand collected in the storage tray needs to be cleaned, the baffle plate only needs to be lifted upwards, and the baffle plate together with the storage tray at the lower end can be taken out of the inspection well, and finally the sand collected in the storage tray can be cleaned conveniently;
[0016] 2. The filter basket is embedded in the dovetail slide groove of the baffle plate by a dovetail slide rod, and the detachable connection between the filter basket and the baffle plate can be realized, so that the impurities filtered out of the filter basket can be cleaned conveniently;
[0017] 3. When the receiving tray needs to be lifted upward, first move the filter basket vertically upward and separate it from the baffle plate. At this time, the blocking plate at the lower end of the connecting column can be removed from the connecting sleeve; then lift the receiving tray upward, and the water gathered above the receiving tray can fall through the drain port. At this time, it can be avoided that the sewage gathered above the receiving tray causes the need to overcome a large sewage gravity when lifting the receiving tray;
[0018] 4. The filter basket can be easily removed by using the handle;
[0019] 5. The filter screen at the outlet pipe can further filter out large particles of impurities, preventing a large number of large particles of impurities from entering the outlet pipe after the filter basket is removed;
[0020] 6. When the baffle plate needs to be lifted upward, the handle groove on the upper end of the baffle plate can be used for holding by hand, thereby facilitating the baffle plate to be lifted upward more conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

Then, the receiving tray 42 is lifted upward, and the water gathered above the receiving tray 42 can fall through the drain port 421. At this time, the sewage gathered above the receiving tray 42 can be prevented from overcoming the greater sewage gravity when lifting the receiving tray 42. Finally, the silt collected in the receiving tray 42 can be easily cleaned.
