[0002] Land comprehensive improvement is a systematic project within a certain area. According to the goals and uses determined by the overall land use plan, with land consolidation, reclamation, development, and the increase and decrease connection of urban and rural construction land as platforms, it promotes the comprehensive improvement of fields, water, roads, forests, and villages, aiming to improve rural production, living conditions, and ecological environment, promote large-scale agricultural operation, concentrated population settlement, and industrial agglomeration development, and advance the process of urban-rural integration. During the land improvement process, ditches need to be built to transport water and irrigate the land to ensure the normal growth of crops inside the land.

[0003] Currently, for the construction of continuous irrigation ditches, usually the bottom of the ditch is poured first, and then the ditch slope is poured, which has the defects of cumbersome construction and long construction period. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, one of the purposes of this application is to provide a construction formwork device for continuous irrigation ditches that is convenient for construction and has a short construction period.

[0005] A construction formwork device for continuous irrigation ditches includes:

[0006] An inner formwork and two outer formworks. The inner formwork is arranged between the two outer formworks. The inner formwork is U-shaped and includes two inner vertical plates and a bottom plate connecting the two inner vertical plates. The tops of the two inner vertical plates are respectively connected to the corresponding outer formworks through a connection structure. The two outer formworks and the inner formwork are used to form a cavity with the bottom of the trench.

[0007] Preferably, the connection structure includes a connecting beam. One end of the connecting beam is connected to the top surface of the inner vertical plate through a first fastening bolt, and the other end of the connecting beam is connected to the top surface of the outer formwork through a second fastening bolt.

[0008] Preferably, the connecting beam is provided with an adjustment waist hole for the second fastening bolt to pass through.

[0009] Preferably, the top surface of the outer formwork is further provided with an anchor hole for setting a first ground anchor.

[0010] Preferably, it further includes a first support frame, which is used to be inserted into the space between the two inner vertical plates and includes two vertical support rods and a crossbar connected to the two vertical support rods and used to be erected on the two inner vertical plates.

[0011] Preferably, it further includes a second support frame for inserting into the inner vertical plate and the outer formwork on the corresponding side. The second support frame includes two vertical support rods II and a rod II that is connected to the two vertical support rods II and is used for erection on the inner vertical plate and the outer formwork on the corresponding side.

[0012] Preferably, it further includes an anti-upward movement mechanism. The anti-upward movement mechanism includes a resisting rod that resists one end of the connecting beam close to the inner vertical plate and a second ground anchor for fixing the resisting rod.

[0013] A construction method uses the construction formwork device in any of the above technical solutions for construction, including:

[0014] Step S1: Fix the two outer formworks in a pre-dug trench;

[0015] Step S2: Place the inner formwork between the two outer formworks. At the same time, connect the top of the inner vertical plate to the outer formwork on the corresponding side through the connecting structure, so that a mold cavity is formed by the two outer formworks, the inner formwork and the bottom of the trench. In summary, the present invention has the following beneficial effects:

[0023] The present invention will be further described below with reference to the drawings through specific embodiments.

[0024] Embodiment:

[0025] A construction formwork device for continuous irrigation ditches, as Figures 1-4 shown, includes an inner formwork 1 and two outer formworks 2. The inner formwork 1 is arranged between the two outer formworks 2. The inner formwork 1 is U-shaped and includes two inner vertical plates 11 and a bottom plate 12 connecting the two inner vertical plates 11. The tops of the two inner vertical plates 11 are respectively connected to the corresponding outer formwork 2 through a connecting structure 3. The connecting structure 3 specifically includes a connecting beam 32. One end of the connecting beam 32 is connected to the top surface of the inner vertical plate 11 through a fastening bolt 32, and the other end of the connecting beam 32 is connected to the top surface of the outer formwork 2 through a fastening bolt 33.

[0026] During specific construction, the following steps are adopted:

[0027] Step S1: Fix the two outer formworks 2 in a pre-dug trench 0;

[0028] Step S2: Place the inner formwork 1 between the two outer formworks 2. At the same time, connect the top of the inner vertical plate 11 to the corresponding outer formwork 2 through the connecting structure 3, so that a mold cavity is formed among the two outer formworks 2, the inner formwork 1 and the bottom of the trench;

[0029] Step S3: Inject slurry into the mold cavity;

[0030] Step S4: When the ditch is formed in the mold cavity, remove the inner formwork 1 and the outer formwork 2.

[0031] The above-mentioned construction formwork device for continuous irrigation ditches directly pours out the ditch. Compared with the prior art method of pouring the ditch bottom first and then the ditch slope, the construction is more convenient and the construction period is shorter. In addition, a mold cavity is formed with the bottom of the trench, eliminating the bottom formwork, simplifying the disassembly and assembly of the formwork, and being beneficial to improving the construction efficiency.

[0032] The top surface of the outer formwork 2 is provided with an adjustment waist hole 30 for the fastening bolt 33 to pass through. By changing the position of the fastening bolt 33 in the adjustment waist hole 30, the position of the inner formwork 1 relative to the outer formwork 2 is adjusted, so as to ensure that the inner formwork 1 is in the exact middle of the two outer formworks 2 and ensure that the wall thicknesses of the two ditch walls of the ditch are the same.

[0033] The top surface of the outer formwork 2 is also provided with an anchor hole 21. The anchor hole 21 is stably fixed by setting a ground anchor one connected to the land.

[0034] It further includes a first support 5, which is inserted into the space between the two inner vertical plates 11. The first support 5 includes two vertical support rods 51 and a first support rod 52 that is connected to the two vertical support rods 51 and is used to be erected on the two inner vertical plates 11. The first support 5 prevents the inner vertical plates 11 from being bulged during pouring, ensuring the pouring thickness of the ditch wall.

[0035] It further includes a second support 6, which is inserted into the inner vertical plate 11 and the outer formwork 2 on the corresponding side. The second support 6 includes two vertical support rods 61 and a second support rod 62 that is connected to the two vertical support rods 61 and is used to be erected on the inner vertical plate 11 and the outer formwork 2 on the corresponding side. The second support 6 prevents the outer formwork 2 and the inner vertical plate 11 from being bulged during pouring, further ensuring the pouring thickness of the ditch wall.

[0036] As Figure 5 shown, it further includes an anti-upward movement mechanism 4. The anti-upward movement mechanism 4 includes a resisting rod 41 that resists one end of the connecting beam 31 close to the inner vertical plate 11 and an anchor 42 for fixing the resisting rod 41. The anchor 42 is connected to the land outside the outer formwork 2. By resisting the connecting beam 32, during pouring, it prevents the inner formwork 1 from moving upward greatly, preventing the bottom of the ditch from becoming thicker, thereby preventing unnecessary waste of slurry and increase in construction costs.

[0037] It further includes a stay cable mechanism 5 connecting the anchor 42 and the outer formwork 2. The stay cable mechanism 5 includes a first cable segment 51 connected to the anchor 42, a second cable segment 52 connected to the outer formwork 2, and a tension adjustment mechanism connecting the first cable segment 51 and the second cable segment 52. The tension adjustment mechanism includes a threaded sleeve 53 and a threaded rod 54 that cooperate with each other. During pouring, the stay cable mechanism 5 can effectively prevent the outer formwork 2 from floating upward greatly, preventing the bottom of the ditch from becoming thicker, thereby preventing unnecessary waste of slurry and increase in construction costs, and the tension adjustment mechanism makes the tension of the stay cable mechanism 5 more appropriate.

[0038] The above embodiments only describe the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various variations and improvements made by those of ordinary skill in the art to the technical solution of the present invention should all fall within the protection scope of the present invention. The technical content claimed by the present invention has been fully recorded in the claims.
