Description

Technical Field

[0001] The utility model relates to the technical field of drainage systems, in particular to an anti-clogging linear drainage ditch applied to a circulation service road in front of an airport terminal building. Background Art

[0002] Airport terminals are characterized by large traffic volumes, so loops are often set up in front of the terminals. Circulars are passages for passenger vehicles. According to relevant regulations, motor vehicles should be parked at designated locations. Parking in loops seriously affects the efficiency of the passage, so long-term parking is not allowed in loops. When there is too much rain, traditional road ditches or linear ditches often become clogged with debris and difficult to clean. If there is too much rain in the loop, vehicles enter frequently, and when a blockage occurs, it is difficult to clean, and long cleaning times will seriously affect the road conditions. For the circular service roads in front of the airport terminal, it is even more necessary to complete the anti-blocking and clearing work as soon as possible after encountering water. Therefore, there is an urgent need to design an anti-blocking linear drainage ditch for the circular service roads in front of the airport terminal. Utility Model Content

[0003] In response to the above technical problems, an anti-clogging linear drainage ditch for the circular service road in front of the airport terminal is provided. The technical means adopted by this utility model are as follows:

[0004] A blockage-resistant linear drainage ditch used for a circular service road in front of an airport terminal comprises a plurality of confluence sections arranged along a curb and cleaning sections arranged at intervals between the confluence sections. The confluence sections comprise height-adjustable strip rainwater grates, below which drainage pipes are arranged. The cleaning sections comprise steel grating rainwater grates and a cleaning well arranged below the steel grating rainwater grates. The drainage pipes converge into the cleaning well. The confluence sections are arranged on the inner side of the curb. The outer edge of the cleaning section protrudes from the curb by a preset distance, and the inner edge is recessed from the curb by a preset distance. The steel grating rainwater grate is arranged in the recessed section.

[0005] Furthermore, the strip rain grate of the confluence section includes several strip holes, the edgemost strip hole is 30±1mm away from the end of the rain grate, the distance between two adjacent strip holes is 20±1mm, the width of a single strip hole is 20±1mm, and the length of a single strip hole is 60±2mm.

[0006] Furthermore, the height-adjustable function of the strip rain grate is realized based on a height-adjusting bracket, and the height-adjusting bracket includes symmetrically arranged angle steels, steel plate brackets, galvanized steel plates, galvanized steel plate welded supports and a connecting piece. The bottom of the angle steel is connected to a pipe fixing structure for installing a drain pipe. The steel plate bracket is arranged on the vertical section of the angle steel, and the galvanized steel plate welded support is arranged above the galvanized steel plate. The strip rain grate is installed through the galvanized steel plate welded support. The height of the galvanized steel plate and the steel plate bracket is adjustable. After adjustment, the steel plate bracket and the galvanized steel plate on both sides are fastened through the connecting piece.

[0007] Furthermore, the pipe fixing structure for installing the drainage pipe includes a frame-type accommodating cavity, the drainage pipe is arranged inside the cavity, and the outside of the cavity is filled with waterproof mortar.

[0008] The utility model adopts a linear drainage design with a large water interception area and no dead angles in road rainwater collection. It not only improves the road rainwater runoff control rate, but also reduces rainwater runoff pollution. The cleaning well is convenient for cleaning and prevents blockage.

[0009] The utility model has the following advantages:

[0010] 1. This utility model is a linear drainage ditch that only occupies 100mm of the width outside the curbstone and does not affect the application of road markings.

[0011] 2. Compared with traditional road side ditches or linear ditches, this new linear drainage ditch greatly improves the aesthetics of the airport circulation service road while ensuring good drainage effect.

[0012] 3. The abandoned flow chute of the utility model adopts a cleaning well to effectively prevent blockage.

[0013] 4. The utility model is easy to disassemble when cleaning the well, does not occupy the motorway area, and ensures the safety of maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS
