Description

Technical Field

[0001] The utility model relates to the technical field of tunnel secondary lining improvement construction, in particular to a lining concrete formwork construction device. Background Art

[0002] With the continuous construction of underground transportation routes such as high-speed railways and bridge tunnels, tunnels that pass through complex geological conditions are becoming more and more common. After the tunnels are completed and put into operation, as the operating time increases, tunnel diseases often occur, including the falling of lining surfaces due to concrete extrusion on the tunnel vault, hollowing out of the upper part of the secondary lining concrete and twisting and deformation of the steel frame, local cracks in the secondary lining on the inner wall of the tunnel, etc., which increase the risk of collapse and seriously threaten driving safety.

[0003] At present, the formwork structure used for tunnel lining reinforcement is too scattered and there are too many of them. It is necessary to set up scaffolding, templates, drill rods and other components. When installing multiple templates, workers need to build a scaffolding platform first, and then stand on the scaffolding platform to build the template. When building the template, workers need to install the single template one by one and use a large number of drill nails to fix it, which is labor-intensive for workers. At the same time, when removing the template and skylight, it is also necessary to manually build a scaffolding platform and dismantle each component one by one, which consumes a lot of time and labor.

[0004] The existing lining concrete formwork construction equipment, in terms of structural design, mostly optimizes and improves the block division and reinforcement of the formwork, but does not play a role in the efficiency of installing the formwork and reducing the labor intensity of workers. Therefore, it is an urgent problem to be solved by those skilled in the art to provide a fast installation lining formwork equipment that can shorten the installation and disassembly period and reduce the labor intensity.

[0051] See also Figure 1The utility model provides a lining concrete mold construction equipment, which includes a pair of positioning mechanisms 1, a pair of arc tracks 2, a power mechanism 3 and a plurality of templates 4. The pair of positioning mechanisms 1 are arranged one by one against the two side walls of the tunnel. The tunnel of the utility model refers to a tunnel after one lining, and the tunnel wall is arc-shaped. The positioning mechanism 1 is arranged at the corner position between the tunnel wall and the bottom surface; the two free ends of the arc track 2 are connected to the pair of positioning mechanisms 1 one by one; the pair of arc tracks 2 are arranged in parallel along a first direction, which is the axial direction of the arc tunnel; the power mechanism 3 is installed on the positioning mechanism 1; the plurality of templates 4 are hinged head to tail in sequence and folded and placed close to a positioning mechanism 1; the power mechanism 3 can drive the template 4 to slide on the pair of arc tracks 2; a plurality of blocking plates 5 are arranged at the gap of the template 4.

[0052] In this embodiment, a pair of positioning mechanisms 1 and a pair of arc tracks 2 are provided, and the symmetrical structure can effectively improve the support strength of the sleeve concrete mold construction equipment and the sliding stability of multiple templates 4. Of course, the specific number of positioning mechanisms 1, arc tracks 2 and power mechanisms 3 can be set according to actual needs.

[0053] The positioning mechanism 1 is set against the side wall of the tunnel, and the tunnel supports and limits the positioning mechanism 1; and the two free ends of the arc track 2 are connected to the paired positioning mechanisms 1 one by one, and the positioning mechanism 1 and the arc track 2 form a stable supporting structure, building a "bridge" for the subsequent installation of multiple templates 4.

[0054] Multiple templates 4 are hinged end to end in sequence and folded and placed close to a positioning mechanism 1. The power mechanism 3 drives the multiple templates 4 to slide on the paired arc tracks 2 until the multiple templates 4 fill the paired arc tracks 2, serving as a supporting structure for the secondary lining. Compared with the traditional method of installing templates 4 one by one on a scaffold, multiple templates 4 are hinged in advance, and the power mechanism 3 drives the multiple templates 4 to slide along the paired arc tracks 2. Multiple templates 4 move from one side positioning mechanism 1 to the other side positioning mechanism 1, which can quickly complete the installation of multiple templates 4 and greatly shorten the installation period of multiple templates 4; the paired arc tracks 2 can support and guide the inner templates 4, greatly reducing the intensity of manual work. Similarly, the power mechanism 3 can also recycle multiple templates 4, greatly shortening the disassembly period of multiple templates 4.

[0055] After completing the installation of multiple templates 4, the gaps of the templates 4 can be blocked by sealing plates 5, and the multiple sealing plates 5 can be fixed at both ends of the templates 4, so that a closed area is formed between the paired arc tracks 2, templates 4, multiple sealing plates 5 and the tunnel wall, thereby improving the stability of the solidification after pouring concrete.

[0056] like Figure 2As shown, the positioning mechanism 1 includes a support frame 11 and a pair of arc-shaped arch frames 12; the support frame 11 is arranged close to the side wall of the tunnel; along the first direction, the pair of arc-shaped arch frames 12 are arranged on both sides of the support frame 11 in a one-to-one correspondence; the arc-shaped arch frames 12 abut against the side wall of the tunnel. Specifically, the shape of the arc-shaped arch frames 12 is adapted to the shape of the side wall of the tunnel, forming a support structure with surface abutment, thereby improving the stability of the support. The support frame 11 is placed on the bottom surface of the tunnel, and forms a support system with the pair of arc-shaped arch frames 12 and the pair of arc-shaped rails 2. The positioning mechanism 1 is limited by the tunnel itself, and has a simple structure and is easy to place.

[0057] Secondly, the positioning mechanism 1 also includes a plurality of adjustment legs 13; the plurality of adjustment legs 13 are arranged at the bottom end of the support frame 11 so as to be able to level the support frame 11. The legs can be screw rods, cylinders, electric push rods or hydraulic cylinders, etc. By adjusting the telescopic length of the legs 13, the height of the support frame 11 can be adjusted accordingly, and the support frame 11 can be leveled, so that the paired support frames 11 are basically at the same horizontal height, further improving the stability of the support limit and improving the adaptability to the flatness of the tunnel bottom surface.

[0058] In addition, the arc track 2 includes a plurality of arc parts connected end to end; the arc arch 12 is connected to the arc parts. In this embodiment, the arc track 2 and the arc parts are both made of I-shaped steel, and the cross-section is concave or L-shaped, or other shapes, as long as they can play a supporting and guiding role for the multiple templates 4. During construction, the multiple arc parts are hoisted to the tunnel wall position one by one, and tightened and fixed using the multiple dowels reserved during the primary lining. In order to further improve the stability of the support, the multiple arc parts can be connected by bolts. Since the multiple dowels can play a positioning role for the multiple arc parts, it is convenient for personnel to operate and reduces labor intensity.

[0059] Furthermore, the power mechanism 3 includes a winch, a cable and a plurality of guides 32; the winch is installed on the positioning mechanism 1, and the number can be set as required; a plurality of guides 32 are provided on the side of the arc track 2 close to the axis; one end of the cable is connected to the winch, and the other end of the cable passes through the plurality of guides 32 in sequence and is connected to the template 4; the winch can retract the cable to drive the plurality of templates 4 to slide along the inner side of the paired arc track 2. The cable can be a steel wire rope or a chain, and the cable abuts against the guide 32, which can guide the cable and prevent the cable from invading the air and interfering with other components; the cable and the guide 32 cooperate with the paired arc track 2 to guide the plurality of templates 4, so that the plurality of templates 4 can slide stably inside the paired arc track 2. The leftmost template 4 of the tunnel among the multiple templates 4 after installation is taken as the first template 43, and the rightmost template 4 is the second template 44, that is, the topmost template 4 of the multiple stacked templates 4 is the first template 43, and the bottommost template 4 is the second template 44 as an example for explanation.

[0060] In one embodiment, the first hoist 31 is installed on the positioning mechanism 1 on the left side of the tunnel, and multiple templates 4 are stacked and placed inside the support frame 11 on the right side of the tunnel. One end of the pull wire is connected to the first hoist 31, and the other end is connected to the first template 43 after passing through multiple guide members 32 in sequence. During the installation operation, the first template 43 is first manually placed in the arc arch 12, and the first hoist 31 is started. The pull wire pulls the first template 43 from the right side of the tunnel along the paired arc tracks 2 to the left side of the tunnel. The first template 43 abuts against the bottom surface of the left side of the tunnel, and the second template 44 abuts against the bottom surface of the right side of the tunnel. During the disassembly operation, the second template 44 is pulled by hand or equipment to recycle multiple templates 4. First, the second template 44 is directly removed from the right side, and then the remaining templates are pulled by the pull wire of the first hoist 31 and slowly lowered into the positioning mechanism 1 on the right side of the tunnel. Then the template 4 is removed, and the above steps are repeated to remove all templates 4 one by one. Both installation and disassembly operations reduce the intensity of manual work.

[0061] In another embodiment, a first winch 31 is installed on the positioning mechanism 1 on the left side of the tunnel, and a second winch 33 is installed on the positioning mechanism 1 on the right side of the tunnel; one end of the first template 43 is connected to the pull wire on the first winch 31, and the other end is connected to the pull wire on the second winch 33. During the installation operation, the first template 43 is first manually placed into the arc-shaped arch frame 12 on the right side, and the first winch 31 is started to reel in the wire, and the pull wire pulls the first template 43 from the right side of the tunnel to the left side of the tunnel; at the same time, the second winch 33 pays out the wire. During the disassembly operation, the first winch 31 pays out the wire, and the second winch 33 reels in the wire, thereby completing the recovery of multiple templates 4. This embodiment does not require manual or external equipment intervention, and the operation efficiency of recovering multiple templates 4 is higher, further reducing the intensity of manual work.

[0062] It should be noted that, due to the limited space in the tunnel, the stacking height of multiple templates 4 may be limited, and they can be installed in multiple batches. For example, if a total of 16 templates 4 are required, 4 templates are installed each time, and the installation is carried out in 4 batches. After all the templates 4 are installed, the multiple batches of templates 4 can be connected.

[0063] Furthermore, the guide member 32 is a concave connector or a guide wheel. The pull wire can be located inside the concave connector, thereby achieving the guiding and limiting operation of the pull wire. The guide wheel can be a guide wheel with an inwardly concave outer ring, and the pull wire is located in the concave position of the guide wheel, which can also play a role in guiding and limiting the pull wire, thereby improving the stability and safety of multiple templates 4 during operation. In one embodiment, a plurality of ear plates are provided on the template 4, and the pull wire is wound around the ear plate, and the height of the ear plate is higher than the installation height of the guide member 32, that is, the ear plate can move in the gap between the guide member 32 and the arc track 2. Of course, the pull wire can also be directly connected to the template 4, as long as the interference between the pull wire and the guide wheel can be avoided.

[0064] See also Figure 3 , a plurality of pulleys 41 are arranged on the template 4; the pulleys 41 can roll in the arc track 2. Compared with the slide rail slider structure of the template 4 and the arc track 2, the pulleys 41 are arranged on the template 4, which can reduce the friction between the template 4 and the arc track 2, improve the stability of the template 4 sliding process, and extend the service life of the equipment.

[0065] like Figure 4 As shown, a pouring window 42 is provided on the template 4, and after the installation of multiple templates 4 and multiple blocking plates 5 is completed, concrete can be poured into the inner wall of the tunnel from the pouring window 42. The pouring window 42 is synchronously set when the template 4 is made, which further improves the working efficiency.

[0066] It should be understood that the above description of the specific embodiments of the utility model is only for illustrating the technical route and features of the utility model, and its purpose is to enable those skilled in the art to understand the content of the utility model and implement it accordingly, but the utility model is not limited to the above specific implementation methods. All changes or modifications made within the scope of the claims of the utility model should be included in the protection scope of the utility model.
