River channel closure method and arrangement structure thereof
The invention discloses a river channel closure method. The river channel closure method comprises the following steps that 1, at the end of a flood season or in the early stage of a dry season, a first-stage diaphragm wall construction platform is pre-occupied; 2, a dike head of the first-stage diaphragm wall construction platform conducts anti-scour protection on the pre-occupied end of the first-stage diaphragm wall construction platform; 3, first-stage diaphragm wall construction is started, and downstream side weir body trailing filling construction of the first-stage diaphragm wall construction platform is conducted; 4, when the flow of a river channel is the dry flow in the dry season, second-stage diaphragm wall construction platform occupation closure is conducted, and a riverbed is cut off; 5, after a second-stage diaphragm wall construction platform occupies the closure cut-off riverbed, second-stage diaphragm wall construction is started, and downstream side weir body trailing filling construction of the second-stage diaphragm wall construction platform is conducted; and 6, after the first-stage diaphragm wall construction platform and the second-stage diaphragm wall construction platform are both occupied, river channel closure is completed. The river channel closure method has the advantages that the closure difficulty is lowered, and the engineering investment is saved. The invention further discloses a river channel closure arrangement structure.
本发明公开了一种河道截流方法。它包括如下步骤，步骤一：在汛末或枯水期前期，进行一期防渗墙施工平台预进占；步骤二：一期防渗墙施工平台堤头对一期防渗墙施工平台预进占端头进行防冲保护；步骤三：开始一期防渗墙施工，一期防渗墙施工平台下游侧堰体尾随填筑施工；步骤四：待河道流量为枯水期较枯流量时，进行二期防渗墙施工平台进占合龙、截断河床；步骤五：二期防渗墙施工平台进占合龙截断河床后，开始二期防渗墙施工，二期防渗墙施工平台下游侧堰体尾随填筑施工；步骤六：一期防渗墙施工平台、二期防渗墙施工平台全部进占后，河道截流完成。本发明具有降低截流难度，节省工程投资的优点。本发明还公开了河道截流布置结构。
