The inner die comprises an upper die 8, a lower die 9 and four pre-tightening support rods 10, the upper die 8 and the lower die 9 are symmetrical U-shaped structures, the outer sides of the U-shaped structures are made of elastic steel plates, grid rib plates are welded on the inner sides of the U-shaped structures, grooves 11 are formed in the top ends of side plates of the U-shaped structures, the joints of the side plates and the bottom plate are arranged to be chamfer structures 12, and pre-tightening gaps 13 are formed in the inner sides of the joints of the side plates and the bottom plate; the four pre-tightening support rods 10 are divided into two groups, namely two groups, and are respectively arranged on the inner sides of the upper die 8 and the lower die 9 at intervals. The inner sides of the upper die 8 and the lower die 9 are provided with rectangular square holes 20 with the same length, and the rectangular square holes 20 are used for the forklift to be inserted to facilitate disassembly and assembly. The pretension bracing piece 10 is two-way screw thread telescopic link, and just, two anti-threaded rods pass through two-way screw thread muffjoint promptly, the detachable connection in the inboard of going up mould 8 or 9 curb plates of lower mould in both ends of pretension bracing piece can realize adjusting the curb plate tensioning through rotatory two-way screw thread sleeve.
The working principle is as follows:
firstly, a front door 1, a rear door 2 and a side door 3 are respectively opened, a reinforcement cage, namely a reinforcing rib (not shown in the figure) arranged inside a water collecting culvert is arranged on a middle positioning step in an outer mold, and a grouting gap is formed between the reinforcement cage and the outer mold under the action of the middle positioning step. Then, the front door 1, the rear door 2 and the side door 3 are sequentially closed and are mutually locked with the supporting bottom plate 5 through the locking mechanism 6.
Then, assemble the centre form into the inboard of steel reinforcement cage again, its step is: firstly, an upper die 8 is placed into a reinforcement cage, two ends of the upper die 8 abut against a concave structure 14 of a front door 1 and a convex structure 15 of a rear door 2, two pre-tightening support rods 10 arranged on the inner side of the upper die are respectively adjusted, two side walls of the upper die 8 are outwards expanded, and the upper die 8 is supported on the upper portion of the reinforcement cage; then, the lower die 9 is placed into the reinforcement cage, two ends of the lower die 9 abut against the recessed structure 14 of the front door 1 and the raised structure 15 of the rear door 2, and two pre-tightening support rods 10 arranged on the inner side of the lower die 9 are respectively adjusted to enable two side walls of the lower die 9 to expand outwards, so that the lower die 9 is supported on the lower portion of the reinforcement cage, and it is noted that the groove 11 of the lower die 9 and the groove 11 of the upper die 8 must be aligned when the lower die 9 is installed and adjusted through the pre-tightening support rods 10. Because the inner mould is positioned by the concave structure 14 of the front door 1 and the convex structure 15 of the rear door 2, the inner mould is supported on the inner side of the reinforcement cage, and a grouting gap is reserved between the inner mould and the reinforcement cage. Further, a vibration base is provided on the outer side of the side door 3, and a vibrator is attached to the vibration base.
And finally, placing the special grouting material hopper on the mold by adopting hoisting equipment, opening the bin gate to perform grouting into the mold, starting the vibrator to tap and exhaust the concrete, closing the bin gate to stop grouting when the mold is filled with the concrete, and naturally solidifying for 12-24 hours. After the solidification time reaches the standard, firstly loosening the pre-tightening support rods 10 on the inner side of the lower die 9 to enable the two side walls to contract inwards, slightly lifting upwards by inserting a forklift into the rectangular square hole 20, and then pulling outwards to take out the rectangular square hole; then the pre-tightening support rods 10 on the inner side of the upper die 8 are loosened, so that the two side walls contract inwards, and the upper die is inserted into the rectangular square hole 20 by a forklift, lifted upwards slightly and pulled outwards to be taken out. After the internal mold is completely taken out, the locking mechanism on the external mold is loosened, the front door 1, the rear door 2 and the side door 3 are opened in sequence, and the formed integrated water collecting culvert is taken out by using a forklift. The whole production process of the integrated water collecting culvert is completed.
