Description

Technical Field

[0001] The utility model relates to the technical field of trapezoidal ditch template construction, in particular to a mechanical trapezoidal ditch template system. Background Art

[0002] In the existing technology, the construction of trapezoidal ditch formwork mostly adopts wooden formwork support. First, the concrete base plate is poured, and then the formwork is nailed together on site to form the opposite wall. Due to the slope of the trapezoidal ditch, workers need to adjust the inclination angle of the formwork and use additional wooden slats, shaping cards or tie bars to support and reinforce the formwork before pouring concrete. After the concrete reaches a certain strength, the formwork is removed and transported.

[0003] However, it is difficult to adjust the formwork. If the adjustment is not accurate or the fixation is not firm, it is easy to cause leakage or even expansion and running of the formwork, which will have a serious impact on the design slope, joint treatment and linear appearance quality of the trapezoidal concrete ditch. Moreover, most of the formwork and the supporting and reinforced wooden nails are a whole piece. The angle of the formwork cannot be adjusted according to the different construction environments. It can only be adjusted and reinforced by repeated nailing and disassembly, resulting in a waste of resources and an increase in construction costs. At the same time, operators take a lot of time to adjust the slope and reinforce the formwork, which reduces construction efficiency, affects the construction progress, and increases construction costs. In addition, the movement of the formwork requires the disassembly of the formwork, supports, nails, reinforcements, steel pipes, etc., and then they are sorted and transported one by one. The ditches are mostly built in fields or hills with complex terrain and narrow roads that are difficult for vehicles to enter. The transfer of formwork and accessories is mainly done by manual transportation, which is very labor-intensive and time-consuming. Utility Model Content
