A method for detecting road diseases by intelligent cruise via an unmanned aerial vehicle (UAV), the UAV and a detecting system therefor are provided. The method for detecting road diseases by intelligent cruise via UAV, wherein a road disease detection model and a road recognition model based on deep learning network are built in the UAV, wherein the method specifically comprises a step of: automatically flying the UAV on a predetermined route on the actual road determined by the road recognition model, and obtaining road disease test results by the road surface disease detection model. The present invention adopts the road recognition model and road disease detection model based on deep learning network, which can realize automatic cruise and automatic road disease detection, only need to set a predetermined route or area range, which is convenient and fast.

A trough plate for constructing a locked polymer anti-seepage wall includes a plate body, a guide tube, a grouting pipe and an anti-blocking head. A construction method of the locked polymer anti-seepage wall includes the steps of positioning an Ntrough plate and then pressing the Ntrough plate into ground, wherein N is a natural number larger than and equal to 1; engaging an (N+1)trough plate with the Ntrough plate, and then pressing the (N+1)trough plate into the ground; connecting a grouting pipe of the Ntrough plate with a grouting machine, pulling out the Ntrough plate, and simultaneously grouting through the grouting pipe of the Ntrough plate by the grouting machine; and repeating the steps (B) and (C) till the locked polymer anti-seepage wall is completed, wherein the steps (B) and (C) are repeated every time, N is automatically increased by 1.
