Hidden city flood prevention wall

Abstract

The invention discloses a hidden city flood prevention wall comprising a plurality of door bodies which are adjacently arranged, and the fracture surfaces of the door bodies are in the shape of inverted T; each door body comprises a water blocking door plate and wing plates located at the bottoms of the back side and the front side of the water blocking door plate; the wing plates are perpendicular to the water blocking door plates; the bottoms of the water blocking door plates are fixed to the top of one side of a water drainage ditch through a plurality of rotating supporting hinges; the water blocking door plates can rotate to the side of the water drainage ditch by 90 degrees from the erected state; when the water blocking door plates rotate to the side of the water drainage ditch by 90 degrees and are in a laid-down state, the water blocking door plates are flush with the municipal road ground; a plurality of telescopic supporting rods are connected in the wing plates of the bottoms of the back sides of the water blocking door plates and can be in lap joint with the top of the other side of the water drainage ditch after being pulled out, and therefore the water blocking door plates can be stabilized in the erected state; and the telescopic supporting rods are connected with the top of the other side of the water drainage ditch in a fastened manner through bolts. The flood prevention wall is safe, economical, convenient and fast to install and easy to store after being used, the city flood prevention requirement can be met, and it is guaranteed that the hidden city flood prevention wall, the urban landscape and roads are harmonious and unified.

Description

technical field [0001] The invention relates to a flood control facility, in particular to a concealed urban flood control wall. Background technique [0002] At present, the existing urban flood control technologies are roughly divided into three types, which are building permanent dams, building temporary water retaining cofferdams with woven bag soil, and installing plug-in retaining walls. The plug-in retaining walls mainly have a base , column, water baffle, and sealing device. The column is fixed on the base through the embedded bolts on the base (that is, the foundation). The water retaining part is a movable baffle. When the flood comes, the movable water baffle is inserted between the two columns. , multiple groups are connected to form a rigid continuous flood wall. [0003] Among them, the first flood control technology of building dams is the traditional flood control method, which is a permanent water-retaining structure. Building a permanent dam for flood cont...

Problems solved by technology

[0003] Among them, the first flood control technology of building dams is the traditional flood control method, which is a permanent water-retaining structure. Building a permanent dam for flood control in the city not only costs a lot, but also brings inconvenience to traffic, is not easy to be hydrophilic, and hinders the layout of environmental landscapes. and other problems, causing the artificial division of the city and destroying the integrity of the city; the second flood control technology of woven bag water retaining cofferdam not only needs to deploy a large amount of manpower and material resources for flood control and emergency rescue, but also has poor anti-leakage effect of the cofferdam. Difficulty in cleaning and other problems; the third type of plug-in retaining wall is an improved urban flood protection device, but there are the following technical problems: ① Before installation, prefabrication of the base and installation of embedded parts are required, and the embedded parts are exposed outdoors for a long time , not only obstructs traffic, but also the pre-embedded bolts are prone to rust and damage, and it is difficult to install once the flood arrives; ② When the flood arrives, the situation is very urgent, and a large number of columns, water retaining plates, and bolts need to be moved and assembled on site, which is not conducive to emergency flood prevention; ③ A large area of ​​retaining wall accessories warehouse needs to be built
