[0002] With the acceleration of the urbanization process, shield tunnel construction plays an increasingly important role in urban infrastructure. Traditional tunnel construction methods have problems such as long construction periods and large environmental impacts. As an important component in shield tunnel construction, the production efficiency and quality of precast culverts directly affect the progress and quality of the entire project.

[0003] The installation and disassembly process of traditional templates is cumbersome and time-consuming. At the same time, the traditional template connection method has problems such as poor stability and easy displacement, which affect the forming quality of the culvert. Moreover, the traditional culvert template connection method may be difficult to disassemble quickly and conveniently after pouring, affecting the continuity and efficiency of the production process. In response to the above problems, this device was invented. Content of the Utility Model

[0024] In order to enable those skilled in the art of this technology to better understand the solution of this application, the following further details the application in combination with the drawings and specific implementation manners.

[0025] Embodiment:

[0026] Referring to Att Figure 1 and Figure 2 , a shield tunnel integral precast box culvert production device in this embodiment includes a base 1, and pillars 16 are fixedly installed at the four corners of the bottom of the base 1.

[0027] Referring to Att Figures 1 - 4 , on both sides of the top of the base 1 in the X-axis direction, first slots 10 are provided. Above the base 1, two first outer templates 11 are arranged. At the bottom of the first outer template 11, first insertion rods 12 adapted to the first slots 10 are fixedly installed. At both sides of the top of the first outer template 11, first connection blocks 18 are fixedly installed. Bolt holes are provided in the first connection blocks 18. During use, through the first slots 10 and the first insertion rods 12, the connection between the first outer template 11 and the base 1 is realized. When the two first outer templates 11 on both sides come into contact, bolts are inserted into the bolt holes, and the assembly between the two first outer templates 11 on both sides is realized by using the first connection blocks 18 and the bolts.

[0028] Referring to Att Figures 1 - 3, on both sides of the top of the base 1 in the Y-axis direction, second slots 13 are provided. Above the base 1, two second outer templates 14 are also provided. At the bottom of the second outer template 14, second insertion rods 15 adapted to the second slots 13 are fixedly installed. The second outer template 14 is connected to the base 1 through the second slots 13 and the second insertion rods 15.

[0029] Refer to the appendix Figure 2 and Figure 4 , on both sides of the outer wall surface of the first outer template 11, second connecting blocks 19 are fixedly installed. A lead screw 20 is threadedly connected to the second connecting block 19. At the inner end of the lead screw 20, a hand ring 21 is fixedly installed. At the outer end of the lead screw 20, a stepped block 22 is fixedly installed. A stop block 23 is provided outside the lead screw 20. A stepped groove adapted to the stepped block 22 is provided on the stop block 23. By providing the stepped block 22 and the stepped groove, the rotational connection between the lead screw 20 and the stop block 23 is realized.

[0030] Among them, the first slot 10, the first insertion rod 12, the second slot 13, and the second insertion rod 15 are all trapezoidal structures, thus ensuring the connection stability between the first outer template 11, the second outer template 14, and the base 1.

[0031] Refer to the appendix Figure 1 and Figure 2 , multiple grouting pipes 17 are connected to the first outer template 11. A forming block 24 is fixedly installed on the second outer template 14, and the total length of the two forming blocks 24 on both sides is equal to the length value of the first outer template 11.

[0032] During use, the operator first realizes the connection between the two first outer templates 11 and the base 1 through the first slots 10 and the first insertion rods 12, and then uses the first connecting block 18 and bolts to assemble the two first outer templates 11. Subsequently, the connection between the two second outer templates 14 and the base 1 is realized by using the second slots 13 and the second insertion rods 15. When the forming blocks 24 on both sides come into contact, the operator rotates the hand ring 21 to realize the rotation of the lead screw 20, and further realizes the movement of the stop block 23. When the inner wall surface of the stop block 23 contacts the second outer template 14, the connection between the first outer template 11 and the second outer template 14 can be realized. At this time, a cavity is formed between the two first outer templates 11 and the second outer templates 14 on both sides. Mortar is injected through the grouting pipes 17, and the mortar solidifies in the cavity to form a culvert.

[0033] Refer to the appendix Figure 3 and Figure 5 , two ejection grooves 2 are provided on the base 1. The two ejection grooves 2 are arranged side by side. An ejection plate 3 is provided in the ejection groove 2. A limit baffle 4 is fixedly installed on the side wall of the ejection groove 2. The limit baffle 4 is used to realize the moving distance of the ejection plate 3. When the bottom of the ejection plate 3 contacts the limit baffle 4 by ejection, the top of the ejection plate 3 just coincides with the top surface of the base 1.

[0034] Refer to the attached Figure 5 , on both sides of the bottom of the ejector plate 3, connecting seats 5 are fixedly installed. On both sides of the ejector groove 2 at the bottom of the base 1, support plates 25 are fixedly installed. A bidirectional screw 6 is rotatably installed between the two support plates 25 on both sides. A transmission assembly 7 is arranged between the two bidirectional screws 6 on both sides. The transmission assembly 7 includes a double-shaft motor 701 arranged below the base 1. There are bevel gear sets 702 between the output shafts at both ends of the double-shaft motor 701 and the bidirectional screws 6 on both sides. On both sides of the bidirectional screw 6, moving seats 8 are threadedly connected. The width of the moving seat 8 is equal to the width value of the ejector groove 2, thus realizing the limit of the moving seat 8, enabling the two moving seats 8 in the same ejector groove 2 to move towards or away from each other during the rotation of the bidirectional screw 6. A support rod 9 is movably installed between the connecting seat 5 and the moving seat 8 arranged on the same side. Under the connection action of the support rod 9, the ejector plate 3 moves longitudinally to realize the ejection of the formed culvert.

[0035] Finally: The above is only the preferred embodiment of the present invention and is not used to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
