Document Type and Number:
WIPO Patent Application WO/2022/120724
Kind Code:
A1
Abstract:
Disclosed is a capillary permeable drainage belt connecting device used for asphalt road reconstruction in old residential areas. The device comprises a fixed housing, a connecting mechanism, needles, drainage grooves, a baffle plate, a collecting mechanism, a collecting box and a filter screen. In the present invention, two capillary drainage belts are clamped to the interiors of two ends of the fixed housing, thereby facilitating the connecting and mounting of the two capillary drainage belts. A plurality of needles are mounted on two sides of the baffle plate, and the capillary drainage belts and the needles are inserted, such that the capillary drainage belts are connected more stably and are not prone to shaking. A plurality of drainage grooves are arranged at the outside of the baffle plate, which facilitate the mutual communication of the two connected capillary drainage belts and thus facilitates the drainage of rainwater. When there is fine gravel and sand in rainwater inside the capillary drainage belts and the fixed housing, the fine gravel and sand are filtered by means of the filter screen and same enters the collecting box and is stored therein; and by means of pulling out the collecting box, the gravel and sand inside the collecting box is cleaned, such that the efficiency of drainage of the capillary drainage belts and the fixed housing is ensured.
