Description

Technical Field

[0001] The utility model relates to the technical field of ditch construction, in particular to a precast mold for the side wall panels of a rectangular ditch. Background Technique

[0002] A municipal rectangular ditch is a drainage ditch with a rectangular cross-sectional shape. The rectangular cross-sectional shape makes the internal flow channel wide and flat, and there are not too many curved parts inside the channel, which can reduce the water flow resistance and make the water flow more smoothly, thereby improving the drainage efficiency. Compared with ditches of other shapes, the bottom width of a rectangular ditch is usually larger, which means it can cover a larger drainage area and effectively collect and discharge more rainwater or sewage. In addition, the construction of a rectangular ditch is relatively simple. Standard molds can be used for prefabrication and then assembled on site. This modular construction method can greatly improve the construction efficiency, shorten the construction period, and rectangular ditches are usually made of concrete or other strong materials, with good structural stability, capable of withstanding large water flow impacts and soil pressures, and not easily deformed or damaged. Generally speaking, the design of a rectangular ditch is reasonable and not easy to be blocked, and its strong structure makes the maintenance cost relatively low. In addition, due to the high drainage efficiency, it can reduce road damage and other problems caused by waterlogging, and further reduce the maintenance cost, so it is widely used.

[0003] In the construction of a municipal rectangular ditch, the prefabrication and installation of the rectangular ditch are important links, and the segmented construction method is often adopted, that is, the side wall part of the rectangular ditch is prefabricated first, then hoisted onto the prepared ditch cushion for installation, and finally the concrete pouring of the ditch bottom plate is carried out. It is an efficient construction method.

[0004] The existing prefabrication method for the side wall panels of a ditch is to make templates with wooden squares, and the templates are connected by driving steel nails. When removing the formwork, the steel nails are pried out again. This method is time-consuming and laborious, causes great damage to the formwork, has a low turnover rate, the formwork is prone to deformation, and there are also certain safety hazards. There are often upward-facing nails, which cause greater disturbance to the concrete when removing the formwork, and are prone to damage the concrete, resulting in a decline in construction quality and other problems. Content of the Utility Model

The limiting template can block a certain height of concrete to form a rectangular notch. The cover plate can block the opening between the limiting template and the side template on the same side to avoid the problem of slurry leakage. The length of rectangular notch one.

[0010] Further, a number of elevation templates are provided below the end template and the side template. The elevation templates include an elevation end template having the same length as the end template and an elevation side template having the same length as the side template. The elevation end template and the elevation side template are respectively located below the end template and the side template and correspond to them. The elevation end template and the elevation side template enclose an elevation rectangular frame.

[0011] Further, limiting rods are fixed on both sides of the adjusting screw rod where the clamping plate is located, and the other ends of the limiting rods penetrate through the fixed block.
