[0035] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] like Figure 1-Figure 6 As shown together, the inclined intercepting ditch formwork structure proposed in this embodiment can be used as a template for pouring concrete on the side wall of the intercepting ditch, and can also be used for pouring concrete on other troughs with an inverted trapezoidal cross-section.

[0037] The intercepting ditch, also known as the sky ditch, refers to the ditch set outside the top of the road cut to intercept the water flowing from the hillside to the roadbed. Generally, after the trench of the intercepting ditch is dug, concrete is poured at the bottom of the trench to form the bottom of the intercepting ditch. Then, the inclined intercepting ditch formwork structure can be used as a template on the bottom to cast the side wall of the intercepting ditch.

[0038] The present inclined intercepting ditch formwork structure comprises a template assembly 1 and a fixing member 2 for fixing the template assembly 1. The template assembly 1 is used as a casting template for pouring concrete to form the side wall of the intercepting ditch; the fixing member 2 is used to stably fix the template assembly 1 in the ditch to prevent the template assembly 1 from shifting during the pouring process.

[0039] In order to ensure that the angle of the side wall of the intercepting ditch cast using the template assembly 1 meets the requirements, the template assembly 1 includes two symmetrically arranged templates 11, the spacing between the bottom ends of the two templates 11 is the bottom width of the intercepting ditch to be formed, and the spacing between the top ends of the two templates 11 is the top width of the intercepting ditch. Trapezoidal brackets 12 are evenly connected between the two templates 11, and the template assembly 1 is placed in the groove of the intercepting ditch.

[0040] The inclination angles of the two templates 11 are respectively the same as the inclination angles of the two side walls. The cross-section of the template assembly 1 is an inverted trapezoid that is basically consistent with the cross-section of the intercepting ditch to be formed. When the two templates 11 are fixed in the groove, concrete is poured between the templates 11 and the side walls of the groove, and the inclined surface and top surface of the formed concrete block meet the construction requirements.

[0041] The trapezoidal brackets 12 evenly connected between the two templates 11 along the length of the two templates 11 can keep the distance between the two templates 11 stable at all times, and the two templates 11 are absolutely symmetrical.

[0042] In order to firmly fix the template assembly 1 in the groove, the fixing member 2 is evenly arranged between the two templates 11. The fixing member 2 includes a lower connecting member 21 embedded in the bottom of the groove, an upper connecting member 22 is connected between the upper edges of the two templates 11, and the upper connecting member 22 and the lower connecting member 21 are connected and tightened by a tensioning member 23. The fixing member 2 can be located between adjacent trapezoidal brackets 12.

[0043] A fixing member 2 is arranged at a certain distance between two templates 11 to ensure that the longer template assembly 1 can be fixed to the bottom with uniform force and will not deviate during the pouring process.

[0044] The lower connecting member 21 is embedded in the concrete at the bottom of the groove, with the top exposed to the concrete. The upper connecting member 22 is arranged between the upper edges of the two templates 11. The upper connecting member 22 and the lower connecting member 21 are aligned up and down. The upper connecting member 22 and the lower connecting member 21 are tightened by the tensioning member 23 to fix the upper connecting member 22 to the bottom surface, thereby positioning the template assembly 1 to the bottom surface.

[0045] In a specific embodiment of the present invention, in order to facilitate pouring, the template 11 includes a rectangular plate, the width of the template 11 is not less than the side wall width of the intercepting ditch, and reinforcing rods 13 are evenly arranged along the width direction of the template 11, and the reinforcing rods 13 are the same length as the template 11.

[0046] The template 11 is adapted to the sidewall of the intercepting ditch, and its width can be slightly wider than the sidewall of the intercepting ditch, so as to be convenient for filling concrete. The angle of the template 11 should be the same as that of the sidewall of the intercepting ditch. A plurality of transverse reinforcing rods 13 on the template 11 can enhance the firmness of the template 11.

[0047] In a specific embodiment of the present invention, the reinforcing rod 13 is arranged on the side of the template 11 facing the symmetry plane, and the smooth side of the template 11 faces the concrete pouring side, so that the poured side wall is smooth and flat.

[0048] In a specific embodiment of the present invention, in order to stably connect the two templates 11, the trapezoidal bracket 12 includes two symmetrically arranged oblique rods 121, an upper connecting rod 122 is connected between the upper ends of the two oblique rods 121, a lower connecting rod 123 is connected between the lower ends of the two oblique rods 121, and a middle connecting rod 124 is connected between the middle parts of the two oblique rods 121. The two oblique rods 121 are respectively fixed on the two templates 11, and the oblique rods 121 are vertically fixed to the reinforcing rods 13. The length of the oblique rod 121 is the distance from the uppermost reinforcing rod 13 to the lowermost reinforcing rod 13.

[0049] The trapezoidal bracket 12, which is symmetrically trapezoidal in shape, is fixed between the two templates 11. The two oblique rods 121 of the trapezoidal bracket 12 are respectively fixed to the reinforcing rods 13 of the two templates 11 by iron nails, and the template assembly 1 presents the shape of a water intercepting ditch.

[0050] In a specific embodiment of the present invention, in order to facilitate tightening and fixing, the lower connecting member 21 includes a U-shaped rod 211, and the two ends of the U-shaped rod 211 are pre-buried in the bottom. The upper connecting member 22 includes a double steel pipe 221 spanned between the upper edges of the two templates 11. The double steel pipe 221 is two steel pipes side by side, and the length of the steel pipe is slightly larger than the distance between the upper edges of the two templates 11. The U-shaped rod 211 and the middle of the double steel pipe 221 are directly opposite each other in the upper and lower parts.

[0051] The arc-shaped rod of the U-shaped rod 211 is exposed at the bottom for easy connection; the double steel pipe 221 is pressed on the upper part of the two templates 11, and is pulled downward by the middle part of the double steel pipe 221 to facilitate the overall balanced positioning of the template assembly 1.

[0052] In a specific embodiment of the present invention, the tensioning member 23 may include a tensioning screw 231, one end of which is set as a hook 232, the hook 232 is hooked on the U-shaped rod 211, the other end of the tensioning screw 231 is passed through the double steel pipes 221, the butterfly buckle 234 at the other end of the tensioning screw 231 is buckled on the double steel pipe 221, and the cast steel nut 235 of the tensioning screw 231 tightens the tensioning screw 231 to tighten the U-shaped rod 211 and the double steel pipe 221.

[0053] One end of the tension screw 231 is bent into a hook 232, and the other end retains a butterfly buckle 234 and a cast steel nut 235. The hook 232 is hooked on the U-shaped rod 211, the tension screw 231 vertically passes between the double steel pipes 221, the two arc buckles of the butterfly buckle 234 are buckled on the double steel pipes 221 respectively, and the cast steel nut 235 is tightened, so that the tension screw 231 tightens the U-shaped rod 211 and the double steel pipes 221, thereby firmly fixing the template assembly 1 at the bottom of the groove.

[0054] In a specific embodiment of the present invention, the template 11 can be a wooden template 11, and the trapezoidal bracket 12 is a wooden bracket. The wooden template 11 and the wooden bracket are connected by iron nails, which is convenient for installation and disassembly. The length of the wooden template 11 can be longer, and a longer side wall can be cast at one time.

[0055] In a specific embodiment of the present invention, a mold release agent is applied to the side of the template 11 facing the side wall of the groove, which facilitates the demoulding after pouring the concrete and ensures the quality of the concrete surface.

[0056] The formwork structure of the sloped intercepting ditch is firmly fixed, the angles of the templates 11 on both sides remain stable, no displacement or deformation occurs during the pouring process, and the angles of the poured sloped side walls are always consistent.

[0057] During the pouring of concrete, the stability of the formwork assembly should be checked at any time. After the pouring is completed, the formwork assembly 1 is removed.
