In addition, those skilled in the art can combine and combine the different embodiments or examples described in the present application and the features of the different embodiments or examples without contradiction.

[0044] The application is described below in combination with Figure 1 , Figure 2 , Figure 3 and Figure 4 , a preparation device for a similar model prefabricated roadway provided by an embodiment of the application is described, which comprises a mold box 1, a roadway mold 2 and a pulling-out device 3.

[0045] As shown in Figure 1 and Figure 2 , the mold box 1 is configured with a receiving cavity, the top of the mold box 1 is provided with an open mouth of the receiving cavity, and the opposite side of the mold box 1 is provided with a mounting hole 11, that is, two mounting holes 11 are arranged on the mold box 1, and the two mounting holes 11 are arranged oppositely.

[0046] As shown in Figures 1 to 3 , the roadway mold 2 adopts a cuboid structure, the two ends of the roadway mold 2 are arranged in the opposite two mounting holes 11, and the length of the roadway mold 2 is greater than the length of the corresponding side of the two mounting holes 11 of the mold box 1. Thus, it can be ensured that one end of the roadway mold 2 is located outside the mold box 1 through the corresponding mounting hole 11. If the roadway mold 2 is relatively long, the two ends of the roadway mold 2 can also be arranged outside the mold box 1 through the corresponding mounting holes 11.

[0047] In this embodiment, the opposite sides of the mold box 1 are provided with corresponding mounting holes 11. The mold box 1 is assembled by four side plates and two bottom plates and connected by bolts, and the mounting holes 11 of the roadway mold 2 are reserved at the designed roadway position, and the roadway mold is arranged through the mounting holes 11 and mounted on the mold box 1.

[0048] As shown in Figure 1 and Figure 4 , the pulling-out device 3 comprises a mounting seat 31 and a jack 32. The mounting seat 31 is sleeved on the protruding end of the roadway mold 2, and the mounting seat 31 is connected with the mold box 1. Thus, the mounting seat 31 can be used to limit the moving direction of the roadway mold 2 when the roadway mold 2 is supported and removed, and it can be ensured that the roadway mold is pulled out straight and does not get stuck. The piston rod of the jack 32 is telescopic along the extension direction of the roadway mold 2, and the jack 32 is arranged opposite to the protruding end of the roadway mold 2. Thus, when the roadway mold 2 is removed by using the jack 32, the stress direction of the roadway mold 2 when pulled out can be ensured, and the problem that the roadway mold 2 has a large resistance and is easily stuck when pulled out in an incorrect direction can be solved.

[0049] Specifically, in the whole process of pouring the model, after the mold box 1 and the roadway mold 2 are assembled, the roadway mold 2 is arranged in the receiving cavity through the mounting hole 11, and it is ensured that one end of the roadway mold 2 is outside the mold box 1.

[0050] After the main structure of the preparation device of the similar model prefabricated roadway is installed, the preparation device of the similar model prefabricated roadway is hoisted in the water tank, so that a large amount of water generated in the model forming process can be conveniently treated. Meanwhile, in order to ensure the flatness of the pouring model, a level meter can be placed in the mold box 1, and the level of the mold box 1 can be checked by adjusting the height of the leveling pad iron around the bottom.

[0051] After the preparation device of the similar model prefabricated roadway is completed, pouring is performed in the accommodating cavity.

[0052] The pulling-out device 3 is arranged on the mold box 1, the mounting seat 31 is sleeved on the protruding end of the roadway mold 2, the piston rod of the jack 32 is opposite to the protruding end of the roadway mold 2, and the piston rod is connected with the roadway mold 2. When the roadway mold 2 is removed by using the jack 32, the stress direction when the roadway mold 2 is pulled out can be ensured.

[0053] The pulling-out device 3 is used to remove the roadway mold 2, and after the roadway mold 2 is removed, the pulling-out device 3 and the mold box 1 are removed. Since the roadway mold 2 is pre-buried in the mold box 1 during pouring, a pouring model containing a roadway can be constructed.

[0054] The preparation device of the similar model prefabricated roadway provided by the application is characterized in that the two ends of the roadway mold 2 are arranged in the two opposite mounting holes 11 of the mold box 1, one end of the roadway mold 2 is arranged outside the mold box through the corresponding mounting hole 11, the mounting seat 31 is sleeved on the protruding end of the roadway mold 2, the piston rod of the jack 32 is telescopic along the extension direction of the roadway mold 2, and the piston rod is arranged opposite to the protruding end of the roadway mold 2. When the roadway mold 2 needs to be pulled out of the mold box, the piston rod can be directly connected with the roadway mold 2, so that the roadway mold 2 can be pulled out straight and does not get stuck, and the difficulty of removing the roadway mold 2 is solved.

The first clamping piece is connected to the top end of the mounting seat 31 through a first connecting plate 34, and the second clamping piece is connected to the bottom end of the mounting seat 31 through a second connecting plate 35. Thus, the fixing of the jack 32 can be completed by using the clamping piece 33 and the connecting plate.

[0058] Since the weight of the jack 32 is large, in order to improve the stability of the overall structure when the roadway mold 2 is pulled out, as shown in Figure 1 and Figure 4 , the pulling-out device 3 further comprises a supporting leg 36.

The oil outlet of the hydraulic pump 37 is communicated with the jack 32, and the hydraulic pump 37 is provided with a control switch for controlling the hydraulic pump. Thus, the movement of the piston rod in the jack 32 can be controlled by the hydraulic pump 37, and the jack 32 is used to move the roadway mold 2 out of the mold box 1.

[0061] Based on the above embodiment, in one embodiment, as shown in Figure 3 , the roadway mold 2 comprises a plurality of side plates 21 and connecting pieces 22. The plurality of side plates 21 are sequentially spliced to form an internally hollow roadway cavity, and adjacent side plates 21 are fixed through the connecting pieces 22.

[0062] Among them, the side plate 21 can adopt a steel plate, and the assembled roadway mold 2 is spliced by four steel plates, and the adjacent steel plates are firmly connected to each other through the connecting pieces 22 and bolts at the joint positions of the adjacent steel plates. The connecting piece 22 is a cuboid steel block, two bolt holes are respectively formed on two faces of the connecting piece 22, and the adjacent steel plates are firmly connected through the connecting piece 22 and the bolts at the joint positions of the adjacent steel plates. Four connecting pieces 22 are respectively arranged at the two ends of the roadway mold.

[0066] After the mold box and the roadway mold are assembled, the roadway mold is arranged in the accommodating cavity through the installation hole, and one end of the roadway mold is ensured to be outside the mold box.

[0067] After the main structure of the whole similar model precast roadway preparation device is installed, the similar model precast roadway preparation device is hoisted in the water tank to facilitate the processing of a large amount of water precipitated in the model forming process. At the same time, in order to ensure the flatness of the pouring model, a level meter can be placed on the mold box, and the height of the leveling pad iron around the bottom is adjusted to check the levelness of the mold box.
