Double-layer cofferdam for water conservancy project construction
The invention discloses a double-layer cofferdam for water conservancy project construction, relates to the technical field of water conservancy projects, and solves the problems that an existing cofferdam is poor in sound insulation and noise reduction effect, the propagation distance of noisy sound generated during construction is long, and living of nearby residents is easily disturbed. The double-layer cofferdam for water conservancy project construction comprises a main cofferdam body, an auxiliary cofferdam body and protruding blocks, wherein the main cofferdam body is of a square structure, a bottom plate is arranged at the bottom of the main cofferdam body, the auxiliary cofferdam is arranged at the top of the bottom plate, the outer walls of the four faces of the main cofferdam are each provided with an outer groove, a set of sliding strips are installed in each outer groove through springs, a blocking weir is installed on the main cofferdam body in a sleeved and sliding mode, the blocking weir is of the square structure, and an outer plate is arranged at the bottom of each of the four outer walls of the main cofferdam body. According to the double-layer cofferdam, the physical diffuse reflection principle is achieved through the unevenness of the four sets of protruding blocks, and the good sound insulation and noise reduction effects are achieved.
本发明公开了一种用于水利工程建设的双层式围堰，涉及水利工程技术领域，解决了现有围堰的隔音降噪的效果较差，施工时发出的嘈杂声传播距离较远，容易干扰附近居民的起居的问题。一种用于水利工程建设的双层式围堰，包括主围堰，副围堰和凸块，所述主围堰为口字形结构，且主围堰的底部设置有一处底板；所述底板的顶部设置有一处副围堰；所述主围堰的四面外壁上均开设有一处外槽，且每处外槽内均通过弹簧安装有一组滑条；所述主围堰上套滑安装有一处挡堰，且挡堰为口字形结构；所述主围堰四面外壁的底部均设置有一处外板。本发明利用四组凸块的凹凸不平做到了物理所述的漫反射原理，起到了较好的隔音降噪效果。
