The invention discloses an automatic processing irrigation truck for concrete pier for bridge pier, and includes a body plate, a bottom plate is fixed on the end surface of the body plate, and a storage block is fixed on the right side of the end surface of the bottom plate. A processing mechanism is provided in the storage block, and the processing mechanism includes a stirring cavity with an opening facing upward. The agitating chamber is used for containing concrete. The agitating chamber is provided with a rotatable drive shaft. Ten ten agitating rods are evenly fixed on the drive shaft. The device can be used for bridge pier during transportation. The processing of concrete, by means of stirring and spiral circulation, can not only make the processing fully, but also prevent the subsequent layering of the concrete, ensure the quality of the concrete, and use spiral transportation when needed.

A working method for a trench-cutting device for underground construction, including the following steps: 1) setting up working platforms in working wells at two ends; 2) mounting the trench-cutting device so that the two ends of the trench-cutting device are each in one of the two working wells respectively; 3) enabling the trench-cutting device to cut along a contour line of an underground construction section; and 4) excavating earth along the contour line. Also disclosed is a trench-cutting device for underground construction, consisting of an excavating device (1) and translation devices (2); the excavating device (1) mainly consists of a frame (1-1), a cutting chain (3) and transmission devices (1-2); the frame (1-1) consists of a frame (1-1-1) in a trench and two end frames (1-1-2) outside of the trench; the two end frames (1-1-2) are respectively connected to the translation devices (2) in the two working wells, the transmission devices (1-2) are mounted on the two end frames (1-1-2), and the translation devices (2) are both arranged in the working wells at the two ends. The working platform is set up in four working wells, concrete may be filled in behind as the trench-cutting device excavates the earth, and then after a closed cavity is formed, work is conducted in the cavity. Also disclosed is a trench-cutting device.

A system includes a processor, an input device, an output device, a memory, and programming in the memory. Execution of the programming by the processor configures the system to perform the following functions. The system receives a foundation file, an initial structure file, and an alternative structure file. The system determines an initial congruency between the foundation file and the initial structure file based on respective boundaries and opening points, and an alternative congruency between the foundation file and the alternative structure file based on respective boundaries and opening points. Based upon the alternative congruency equaling or exceeding the initial congruency, the system outputs a valid pairing between the foundation file and the alternative structure file.
