[0002] Drainage ditches are necessary structures in engineering projects and are widely used in permanent and temporary projects. Conventional drainage ditch construction mainly uses cast-in-place reinforced concrete or plain concrete. Since the drainage ditch structure is generally small in size, has many edges and corners, and has thin walls, the on-site construction process involves multiple processes such as formwork, demoulding, and pouring. After the construction is completed, the drainage ditch surface is rough, the gloss is poor, the construction joints seepage, the drainage is not smooth, there are cracks and missing corners, and the line is not straight. In order to avoid the above-mentioned quality defects, U-shaped prefabricated assembled concrete drainage ditches are mostly used nowadays.

After the drain ditch is transported to the construction site, it is manually transported and slid into the excavated trench using steel pipes and slings or seesaws, and then it is straightened and assembled piece by piece using crowbars. There are many safety hazards, low construction efficiency, long construction period, large labor consumption and high cost. Utility Model Content

The X-shaped claw 54 is hinged at the intersection and can be opened or closed around the hinge axis. The lower end extends vertically downward to form a clamping section. The opposite end surfaces of the pair of clamping sections serve as clamping surfaces. The rubber plates 55 are arranged on the clamping surfaces. The opposite end surfaces of the pair of rubber plates 55 are provided with a plurality of horizontal convex ribs 56.
