Abstract

The invention provides an assembled drainage device. The assembled drainage device comprises multiple drainage ditch units; each drainage ditch unit comprises a lower base plate, and two side plates correspondingly connected to two opposite ends of the lower base plate in the width direction; an accommodating cavity opened at the upper end is surrounded by the lower base plate and the two side plates; the multiple drainage ditch units are connected in sequence to communicate with the accommodating cavity; the upper ends of the side plates of the multiple drainage ditch units are leveled; a paving layer with a preset slope is arranged on the inner surface of the lower base plate of each drainage ditch unit in the length direction; and the paving layers in junctions of the adjacent drainageditch units are smoothly connected. The assembled drainage device can implement longitudinal drainage without depending on the terrain; and through connecting arrangement of the lower base plate and the two side plates, the drainage device achieves higher stability.

Description

technical field [0001] The invention relates to the technical field of drainage, in particular to an assembled drainage device. Background technique [0002] It is advisable to design self-contained vertical and horizontal drainage ditches near the base of urban rail transit vehicles to introduce accumulated water into the local drainage system. The horizontal direction refers to the direction parallel to the horizontal plane, and the longitudinal direction refers to the direction perpendicular to the horizontal plane. . The vertical drainage equipment is mainly used to collect rainwater between the stock roads and the outside of the enclosure wall. The vertical slope ratio should not be less than 2‰, and should not be less than 1‰ under difficult conditions, so as to ensure that the collected rainwater can quickly achieve gravity drainage and prevent water accumulation. cause roadbed damage. [0003] The drainage ditch is made by workers on-site molding and cast-in-place ...
