Overflow confluence diversion and self-breaking dam earthwork plate and extraordinary flood diversion channel

Abstract

Overflow confluence diversion and self-breaking dam earthwork plate and extraordinary flood diversion channel belongs to the water conservancy project of the spillway project and the defense field ofthe dam to deal with the water attack. The project mainly includes the following steps: overflow, confluence diversion and self-breaking dam are quantized and designed ; the overflow, confluence diversion and self-breaking dam (1) comprises a road-edge stone overflow, confluence diversion and self-breaking dam (1-a), an upstream sub-bank road edge stone overflow, confluence diversion and self-breaking dam (1-b), a pipe belt and a road-edge stone overflow, confluence diversion and self-breaking dam (1-c) ; the earthwork plate of the earthwork plate and extraordinary flood diversion channel (2)is formed by a plurality of fish scale-shaped units, the fish scale-shaped units are arranged in an area with high flow velocity, and are divided into a earthwork plate seamless connection (II-I), horizontal-seam fish scale-shaped connection (II-II) according to the connection type of the fish scale-shaped unit. The present invention is applicable to the controllable automatic flood diversion of areservoir sub-dam, a main dam, a higher levee and a higher drainage head dam, and has simple structure, low cost and no permanent land occupation.

Description

technical field

[0001] The invention belongs to the technical field of dike and dam extreme flood diversion engineering, and also belongs to the technical field of national defense against water attack, and specifically relates to a design method of a self-collapsing embankment and a geotechnical plate extreme flood diversion channel. Background technique

[0002] Japan, 2018 July 5, 2018, the western part of Japan experienced heavy rain. A river in Mabi-cho, Kurashiki City burst its embankment. The flood destroyed about one-third of the houses, forcing thousands of people to climb on the roof for help. In Mabi-cho alone, at least 28 people were injured. People were killed, and the Japanese authorities issued evacuation orders to 5 million people when the rain was at its worst, but many people did not take these orders seriously. Under the theoretical and technical conditions, "Wolf is coming" is a worldwide social problem. Japan's No. 10 typhoon "Lion Rock" in 2016 caused ...

[0035]Example 1: Watershed flood diversion system, the embankment of a certain river basin adopts the super flood channel of the geotechnical slab of the overflow and confluence diversion self-collapsing embankment, and the overflow and confluence diversion and flushing self-collapsing dam 1 is designed according to the flood prevention and mitigation design theory of the flood confluence diversion self-collapsing embankment. Standard flood dam disaster prevention and reduction theory design geoslab very flood channel 2, overflow confluence diversion self-break dam 1 bottom connects geoslab very flood channel 2, geoslab very flood channel 2 both sides connect embankment bank 3; super standard flood dam protection The theory of disaster reduction, which is to determine the structural form and scale of the special flood channel of the geotechnical board according to the flood damage mechanism of flood discharge and beach fields and the goal of disaster prevention and reduction, an...

[0054] Embodiment 2, the extreme flood diversion of war water attack and the extraordinary flood diversion of rivers crossing the border rivers between countries: 1) prevent war water attack, adopt the method of decentralized flood diversion and decentralized water storage, and use self-breaking dams and extraordinary spillways of geosynthetic materials for emergency response To deal with war water attack; to deal with the dam break and surge disaster caused by the water attack of the upstream reservoir, it is now built at the auxiliary dam of the reservoir and the low dam on the bank to prevent or reduce the dam break disaster; at the head of the canal The dikes or barrages on both sides of the project are built to prevent the dam break surge from destroying the canal head project; the upstream flood diversion gates of the rivers are built to prevent the dam break surge from destroying the flood diversion gates and diverting; the dikes on both sides of the river are scattered t...

Embodiment 3

[0055]Example 3, example of flood diversion and protection dams: A small cross-border river does not have the conditions to build a flood detention area. Building a flood diversion gate is not only expensive, but it is also difficult to manage far away from villages. Concentrating on flooding one place is unfairly opposed. In view of this situation, the present invention is adopted to distribute floods in a balanced manner to the beach fields, the low-standard flood floods are diverted using a fixed-period rotation system, and an automatic forecasting system is set at the flood diversions. Due to the low cost of the present invention, unmanned management, automatic and controllable flood diversion is economically and technically feasible; because of its fair flood diversion, residents and farmers can accept and solve the difficult problem of flood protection embankment site selection and management problems in non-flood detention areas; because there are definite Flood diversi...
