Description

Technical Field

[0001] The invention relates to the technical field of water conservancy project construction, in particular to a forming die for a cast-in-situ ecological slope protection grid beam. Background Art

[0002] During the construction of highways, railways, water conservancy projects and other projects, there is often a large amount of excavation. Especially during the construction of water conservancy projects, a large number of exposed slopes will be formed on both sides of the river. Since there are no trees and vegetation on the slopes, the soil on both sides of the river will flow into the river under the erosion of rainwater on rainy days, which will not only cause soil erosion, but also increase the safety risks of river dams. Therefore, it is necessary to protect and manage the slopes on both sides of the river.

[0003] Most of the slope protection methods currently used use concrete materials to cast grid beams on the earth slope, and then plant vegetation. During the construction process of casting the grid beams, a casting chamber is set up through multiple molds, and then concrete is filled into the casting chamber. After the concrete solidifies and forms, the mold is removed to realize the grid beam casting construction. However, since the bottom of the existing mold is flat and the surface of the earth slope is uneven, there is a gap between the bottom of the built mold and the earth slope. During pouring, concrete will flow out of the gap and cause waste. In addition, the existing mold is relatively troublesome to build. Therefore, a forming mold for cast-in-place ecological slope protection grid beams is proposed. Summary of the Invention

[0030] When the device of the present invention is in use, the mold outer frame 1 and the mold inner frame 2 are first placed on the earth slope of the river channel. After determining the position, the rocker 25 in the rod groove 26 is pulled out, and the rocker 25 is rotated to drive the rotating shaft 21 to rotate.

The thread is used to control the downward movement of the fixing rod 12 so that the fixing rod 12 is inserted into the soil of the earth slope to fix the mold frame. After that, the mold can be spliced according to the grid beam structure, and the two clamping rods 34 on the other mold outer frame 1 are inserted into the two clamping grooves 33 of the fixed mold outer frame 1. During the insertion process of the clamping rod 34, the clamping rod 34 will squeeze the inclined surface of the limit block 36, and push the limit block 36 completely into the groove 35. After 33, the limit groove 40 on the card rod 34 corresponds to the groove 35. Under the action of the third spring 39, the limit block 36 enters the limit groove 40 to limit and fix the card rod 34, completing the splicing of the two molds. After the mold frame is erected, the mold cover 4 is covered. When the insertion rod 6 on the mold cover 4 is inserted into the insertion hole 5 of the mold outer frame 1 and the mold inner frame 2, the insertion rod 6 will extend into the movable cavity 27 to push the movable plate 28. After the movable plate 28 slides down, the baffle 30 will extend from the slide groove 29 and be inserted into the soil slope. Multiple baffle rods 30 will fill the gap between the bottom of the mold and the soil slope, which can avoid leakage of concrete during pouring, effectively preventing waste of concrete. During the concrete pouring process, only the highest mold needs to be grouted, and the concrete slurry will flow through the through port 8 to the molds below, thereby improving the pouring and grouting efficiency.
