Positioning device and construction method of prestressed corrugated pipe

LIU WEI

The invention discloses a positioning device for a prestressed corrugated pipe and a construction method thereof.The positioning device comprises a plurality of supports arranged at intervals in the installation direction of the prestressed corrugated pipe, and the top of each support is provided with an arc-shaped contact face matched with the bottom of the prestressed corrugated pipe; the bottoms of the arc-shaped contact surfaces are detachably arranged on the mounting beam bottom of the prestressed corrugated pipe, and the arc-shaped contact surfaces are in contact with the wave troughs of the prestressed corrugated pipe. According to the positioning device, the prestressed corrugated pipe is supported by the supports, the supports are arranged between the prestressed corrugated pipe and the bottom of the mounting beam at intervals, and due to the fact that the supports are matched with the adjusting nuts through the harness screws, the height of the supports can be adjusted conveniently, and maintenance is convenient; meanwhile, the arc-shaped contact surfaces matched with the troughs of the prestressed corrugated pipe are arranged on the bracket, so that the prestressed corrugated pipe can be conveniently clamped to be prevented from moving, the prestressed corrugated pipe can be mounted according to design requirements, and the requirement of prestress is met.

本发明公开了一种预应力波纹管的定位装置及其施工方法，定位装置包括沿预应力波纹管安装方向间隔设置的多个支架，每个支架的顶部均设置有与预应力波纹管底部配合的弧形接触面，其底部均能够拆卸地设置在预应力波纹管的安装梁底上，弧形接触面与预应力波纹管的波谷处接触。本发明的定位装置借助若干个支架将预应力波纹管支撑起来，这些支架间隔设置在预应力波纹管和安装梁底之间，由于支架采用通丝螺杆与调节螺母的配合，方便调节支架的高度，维修便利，同时支架上设置有与预应力波纹管的波谷相配合的弧形接触面，方便卡住预应力波纹管，以防止预应力波纹管移动，使其可以按照设计要求进行安装，满足预应力的要求。
