Description

Technical Field

[0001] This utility model relates to the field of road drainage technology, specifically to a drainage structure for construction roads. Background Technology

[0002] Road drainage is a structure that combines road engineering to remove rainwater and snowmelt from road surfaces and the ground, urban wastewater, groundwater, and to lower the groundwater level. Road drainage is mainly divided into surface drainage, roadside drainage, and underground drainage. Surface drainage conducts rainwater and snowmelt from the center of the road to the sides, and then the roadside drainage structure guides it into the underground drainage system. However, many existing drainage structures suffer from blocked roadside drainage channels and underground drainage due to untimely roadside drainage or lack of filtration and separation of impurities, easily leading to roadside water accumulation. Utility Model Content

[0003] I. Technical problems to be solved

[0004] The technical problem this invention aims to solve is that the drainage efficiency is low and not timely, and impurities are not filtered and separated, which can block the channels between roadside drainage and underground drainage, easily leading to roadside water accumulation.

[0005] II. Technical Solution

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a drainage structure for construction roads, including a drainage ditch and a filter screen. The top of the drainage ditch is provided with grooves on both sides. The filter screen is detachably placed on the drainage ditch in cooperation with the grooves on both sides. A re-filtration component that can filter small floating objects and impurities in rainwater is connected to the filter screen. Several sedimentation tanks are provided in the drainage ditch. A drainage channel is connected to the drainage ditch below the sedimentation tanks. A telescopic connecting pipe is connected between the drainage channel and the drainage ditch. The upper surface of the connecting pipe extends out of the sedimentation tanks. A rapid water guiding component is connected to the connecting pipe.

[0007] Furthermore, the re-filtration assembly includes protrusions connected to both sides of the drainage ditch. A connecting ear is connected to the middle of the bottom end of the filter grid. A connecting shaft is provided on the connecting ear. Filter plates are respectively hinged to both sides of the connecting shaft. The free ends of the filter plates overlap the protrusions, so that the filter plates on both sides are unfolded and the free ends slide down the drainage ditch until the filter grid and the groove are engaged. At this time, the free ends of the filter plates abut against the protrusions under the action of gravity.

[0008] Furthermore, the filter plate is provided with a groove on one side and a hinge seat on the other side. The hinge seat and the groove are hinged together by a connecting shaft and a connecting ear, which facilitates the hinged connection of the filter plate with the hinge shaft in pairs. This ensures that rainwater must be filtered through the filter plate before being introduced into the drainage ditch below, avoiding dead corners in the filtration process.

[0009] Further, the connecting ears are provided with through holes, and the connecting shafts are matched with the through holes, so that the filter plate can be matched with the drainage ditch with different widths.

[0010] Further, the rapid water guide assembly comprises a plurality of U-shaped pipes connected to the top end of the connecting pipe in a circumferential direction, and the U-shaped pipes are arranged in an inverted mode.

[0011] Further, the middle part of the connecting pipe is provided with an elastic pipe, and the connecting pipe is provided with a connecting plate at one end close to the elastic pipe.

[0012] III. Advantages

[0013] Compared with the prior art, the construction road drainage structure has the following advantages:

[0014] The filter grid can filter large impurities in the rainwater flow, and reduce the filtering burden of the re-filtering assembly.The re-filtering assembly can filter and screen out small impurities and floating objects in the rainwater. The filtered rainwater is guided into the drainage ditch. The elastic pipe of the connecting pipe can adjust the height of the drainage liquid level. BRIEF DESCRIPTION OF DRAWINGS
