Description

Technical Field

[0001] The utility model relates to the field of municipal engineering facilities, in particular to a drainage ditch structure for municipal engineering. Background Technique

[0002] A drainage ditch refers to a channel used to drain accumulated water and sewage, which mainly has the following functions: (1) It plays a role in drainage. During the rainy season or when floods come, the drainage ditch can quickly guide rainwater and floods into rivers or sewers, preventing water accumulation and reducing the occurrence of flood disasters; (2) It plays a role in purifying water quality. After the wastewater generated by urban living and industrial activities is treated by a sewage treatment plant, it needs to be discharged into rivers or the ocean through the drainage ditch; (3) It plays a role in ventilation. Since the length of the drainage holes is relatively long, there is often a certain air flow inside, which can reduce the accumulation of gases in the ditch, ensure good circulation of other substances in the ditch, and avoid the accumulation of malodorous gases.

[0003] The installation height of the existing prefabricated drainage ditch is not adjustable. As a result, if the depth of excavation at the construction site is too large or too small, the depth needs to be continuously adjusted to make the drainage ditch flush with the ground after installation, which is inconvenient during the construction process. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drainage ditch structure for municipal engineering, which has the function of adjustable height and is convenient to be flush with the ground.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A drainage ditch structure for municipal engineering includes a groove with a "U"-shaped cross-section and a grille cover plate arranged in the groove. Support members are detachably connected to both sides of the groove. The support members include a lifting part that is inverted "U"-shaped and is arranged to lift on the edge of the groove, and a placing part that is arranged on one side of the lifting part close to the middle of the groove and extends along the horizontal direction. Height adjustment components for adjusting the height of the placing part are respectively arranged between the two inner side surfaces of the groove and the two placing parts. The two sides of the grille cover plate are placed on the two placing parts, and the upper surface of the grille cover plate and the upper surface of the lifting part are at the same height.

[0006] By adopting the above technical solutions, when the height of the grille cover plate is too high or too low, the height of the support member can be adjusted through the height adjustment component, which has the function of conveniently adjusting the installation height of the grille cover plate. Thus, when the grille cover plate is placed on the placing parts of the two support members, it is convenient to make the height of the grille cover plate flush with the ground height.

[0007] A further setting of the present utility model is as follows: A plurality of recessed portions with a "U"-shaped cross-section are provided on the placing portion. The height adjustment assembly includes a support platform provided on the inner side surface of the groove and corresponding to the recessed portion, an adjustment screw provided on the support platform and passing through the recessed portion, and two adjustment nuts threadedly connected to the adjustment screw and respectively abutting against the upper and lower surfaces of the bottom of the recessed portion. The upper end of the adjustment screw is located inside the recessed portion.

[0008] By adopting the above technical solution, when adjusting the height of the placing portion of the support member, first loosen the upper adjustment nut, and the height of the placing portion of the support member can be adjusted by adjusting the lower adjustment nut. Then, fix the placing portion of the support member by tightening the upper adjustment nut, and finally, the height of the support member is adjusted.

[0009] A further setting of the present utility model is as follows: A plurality of positioning sleeves are provided on the two outer side surfaces of the groove, and a plurality of positioning pieces respectively passing through the positioning sleeves are provided at the bottom of the side of the lifting portion away from the placing portion.

[0010] By adopting the above technical solution, the setting of the positioning sleeve and the positioning piece can realize the positioning of the installation of the groove and the support member.

[0011] A further setting of the present utility model is as follows: Rubber buffer sheets are provided on both sides of the grille cover plate and are placed on the placing portion.

[0012] By adopting the above technical solution, the rubber buffer sheets on both sides of the grille cover plate can play a role in buffering and shock absorption, thereby reducing the occurrence of vibration of the grille cover plate.

[0013] A further setting of the present utility model is as follows: A compression spring is sleeved on the part of the adjustment screw located between the recessed portion and the support platform. An enhancing arm with an upwardly protruding arc in the middle is provided between the corresponding two adjustment screws. The middle of the enhancing arm abuts against the lower adjustment nut, and both ends of the enhancing arm abut against the lower surface of the bottom of the recessed portion under the action of the compression spring.

[0014] By adopting the above technical solution, the setting of the enhancing arm can realize the support by abutting against the lower surface of the grille cover plate, thereby improving the structural stability of the grille cover plate. BRIEF DESCRIPTION OF THE DRAWINGS
