Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction lining equipment, in particular to an adjustable lining trolley end formwork assembly. Background Technique

[0002] Most railway engineering tunnels are constructed using the New Austrian Tunneling Method. Under the premise of utilizing the bearing capacity of the surrounding rock itself, millisecond blasting and smooth blasting techniques are used for the excavation of the tunnel body, and the tunnel body is constructed with a composite inner and outer two-layer lining formed by the primary support and the secondary lining. At present, due to the change of the lining type after the secondary lining construction of the tunnel, the lining thickness has different structural thicknesses such as 50 cm, 60 cm, 70 cm, 80 cm, etc., so it is necessary to replace the end formwork of different lining trolleys to meet the requirements of lining construction, resulting in a waste of resources. In addition, the problem of water seepage at the construction joint of the railway tunnel secondary lining is also one of the common problems in tunnel construction quality, causing difficulties in maintenance during the operation period and waste of costs.

[0003] In the prior art, in order to ensure that the lining end formwork can be applicable to different lining thicknesses and solve the problem of water seepage at the secondary lining construction joint, the commonly used method is to set two formworks, one of which can be adjusted up and down to meet different lining thicknesses; the other formwork is fixedly arranged on the lining trolley and a transverse positioning clip groove for inserting a positioning clip is processed in the middle, and the positioning clip is used to connect the embedded waterstop and manually adjust the position of the waterstop, so as to solve the problem of water seepage at the secondary lining construction joint.

[0004] In the actual construction, the embedded waterstop should be set in the middle position of the lining. Therefore, when the lining thickness changes, the position of the embedded waterstop also needs to be adjusted. However, in the prior art, there are often errors in manually adjusting the position of the waterstop, resulting in inaccurate setting of the position of the embedded waterstop. And when the lining thickness changes, it is necessary to manually adjust the position of the formwork, manually adjust the position of the embedded waterstop, and also disassemble and install the positioning clip. The whole adjustment process is relatively complex, time-consuming, and the manual labor intensity is relatively large. Therefore, it is necessary to develop a lining trolley end formwork assembly that can improve construction efficiency, reduce labor intensity, and ensure that the position of the embedded waterstop is always accurate.

[0023] Advantages of the present utility model:

[0024] An adjustable end formwork assembly for a lining trolley provided by the present utility model includes a bottom connecting block, an end formwork, a middle-buried waterstop and a formwork adjusting block. One of the bottom connecting block and the end formwork is provided with a connecting hole, and the other is provided with a plurality of positioning holes arranged in the vertical direction in sequence.

[0043] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0044] like Figure 1 - Figure 2 As shown, the utility model provides an adjustable lining trolley end template assembly, including a bottom connecting block 1, an end template 2, an embedded water stop 3 and a template adjustment block 4. The bottom connecting block 1 is fixedly connected to the lining trolley 1000; the bottom connecting block 1 and the end template 2, one is provided with a connecting hole 100, and the other is provided with a plurality of positioning holes 200 in sequence along the vertical direction. When the connecting hole 100 is connected with different positioning holes 200 and a connecting piece is passed through, the height position of the end template 2 relative to the bottom connecting block 1 is different, and a locking mechanism 20 is provided on the end template 2; the locking mechanism 20 locks and connects the embedded waterstop 3, and the vertical distance from the embedded waterstop 3 to the reference plane of the lining trolley 1000 is the water-stop height; the template adjustment block 4 can be selectively connected to the end template 2, and the adjustable lining trolley end template assembly has an initial state and an increased state. In the initial state, the end template 2 works alone, and the vertical distance from the top of the end template 2 to the reference plane is the working height. In the increased state, the template adjustment block 4 is connected to the end template 2, and the vertical distance from the top of the template adjustment block 4 to the reference plane is the working height. At this time, the water-stop height is half of the working height.

[0045] In the present invention, the bottom connection block 1 and the end template 2 can be connected by connecting the connecting piece through the connecting hole 100 and the positioning hole 200. When the connecting hole 100 is connected to different positioning holes 200, the top of the end template 2 is at a different height relative to the reference plane of the lining trolley 1000, so that different lining thicknesses can be adapted. At the same time, a locking mechanism 20 is provided on the end template 2 to lock and connect the embedded water stop 3, so that the position of the embedded water stop 3 can move with the end template 2. In the initial state of the adjustable lining trolley end template assembly, the end template 2 operates alone, and the height of the embedded waterstop 3 to the reference plane is half of the height of the top of the end template 2 to the reference plane. At this time, the waterstop height is half of the working height, and the waterstop effect is the best; in the height adjustment state, the end template 2 moves up relative to the bottom connection block 1, and the setting position of the embedded waterstop 3 also moves the same distance. At this time, a template adjustment block 4 is connected to the end template 2, so that the height of the embedded waterstop 3 to the reference plane is half of the height of the top of the template adjustment block 4 to the reference plane. At this time, the waterstop height is still half of the working height. Therefore, when the lining thickness changes, it is only necessary to manually adjust the position of the end template, and there is no need to manually re-position the position of the embedded waterstop, which improves construction efficiency, reduces labor intensity, and ensures the accuracy of the position of the embedded waterstop.

[0046] Specifically, Figure 1 As shown, a plurality of connection holes 100 are provided, and the plurality of connection holes 100 are arranged in sequence along the vertical direction. A connection hole 100 and a positioning hole 200 are penetrated by a connecting piece to form a connection portion. The bottom connection block 1 and the end template 2 are connected by at least one connection portion to improve the stability of the connection between the bottom connection block 1 and the end template 2.

[0047] In this embodiment, the connecting member is a pin shaft, and the bottom connecting block 1 is sequentially provided with 4 connecting holes 100 along the vertical direction, and the spacing between two adjacent connecting holes 100 is 5 cm. The end template 2 is sequentially provided with 4 positioning holes 200 along the vertical direction, and the spacing between two adjacent positioning holes 200 is 5 cm. During on-site construction, when the lining thickness is 50cm, the embedded waterstop 3 is set at a lining thickness of 25cm, and the four connecting holes 100 on the bottom connecting block 1 correspond to the four positioning holes 200 on the end template 2. A corresponding connecting hole 100 and a positioning hole 200 form a group, and each group of connecting holes 100 and positioning holes 200 are connected by pins, which improves the stability of the connection between the bottom connecting block 1 and the end template 2; when the lining thickness is 60cm, first flip the template adjustment block 4 with a vertical dimension of 5cm and connect it to the end template 2, and then move the end template 2 upward by 5cm, so that the three positioning holes 200 on the end template 2 correspond to the three connecting holes 100 on the bottom connecting block 1, and each group of connecting holes 100 and positioning holes 200 are connected by pins. At this time, it can meet the requirement of a lining thickness of 60cm and ensure that the embedded waterstop 3 is set at a position of 30cm. On the contrary, to adjust the lining thickness from 60 cm to 50 cm, it is only necessary to first move the end template 2 downward by 5 cm and then remove the template adjustment block 4 from the end template 2.

[0048] In other embodiments, the connecting parts can also be bolts, rivets, etc. The number of connecting holes 100 and positioning holes 200 is not necessarily the same, and is not limited to 4, and can be set according to specific circumstances; secondly, the spacing between two adjacent connecting holes 100 or two adjacent connecting holes 200 can be adjusted according to specific construction conditions.

[0049] More specifically, the end template 2 includes a lower ring template 21 and an upper ring template 22, and the lower ring template 21 is provided with a connection hole 100 or a positioning hole 200; the upper ring template 22 is connected to the lower ring template 21, and the embedded water stop 3 is sandwiched between the lower ring template 21 and the upper ring template 22. By setting the end template 2 in the form of connecting the upper ring template 22 and the lower ring template 21, the problem of difficulty in installation due to the large overall volume of the end template 2 is solved. In addition, sandwiching the embedded water stop 3 between the lower ring template 21 and the upper ring template 22 not only simplifies the structure, but also makes the embedded water stop 3 more stable and not easy to shift.

[0050] More specifically, the upper ring template 22 is rotatably connected to the lower ring template 21, which is more convenient for the installation and disassembly of the upper ring template 22 and the lower ring template 21. In this embodiment, the upper ring template 22 and the lower ring template 21 are connected by a pin shaft. During installation, only the upper ring template 22 and the lower ring template 21 need to be penetrated and connected by the pin shaft, and then the upper ring template 22 is flipped to complete the clamping of the embedded waterstop 3; during disassembly, only the locking of the pin shaft needs to be released, and the upper ring template 22 is flipped to loosen the embedded waterstop 3 to complete the disassembly. It can be seen that the installation and disassembly of the upper ring template 22 and the lower ring template 21 are simple and convenient.

[0051] More specifically, a support portion 211 is provided on the lower ring template 21, and a fixing portion 221 is provided on the upper ring template 22. The support portion 211 and the fixing portion 221 constitute a locking mechanism 20. The support portion 211 is rotatably connected to the fixing portion 221, and the embedded waterstop 3 is clamped between the support portion 211 and the fixing portion 221. By providing the support portion 211 and the fixing portion 221, the embedded waterstop 3 can be kept horizontally straight and does not shift. In this embodiment, the dimension of the support portion 211 in the horizontal direction is larger than that of the lower ring template 21, and the dimension of the fixing portion 221 in the horizontal direction is larger than that of the upper ring template 22. The lengths of the support portion 211 and the fixing portion 221 in the horizontal direction are not less than half of the length of the embedded waterstop 3, so that the embedded waterstop 3 can be horizontally straight and does not shift during construction, and it can be ensured that the embedded length and the exposed length of the embedded waterstop 3 are each half. At this time, the embedded waterstop 3 has a better waterstop effect.

[0052] Specifically, as Figure 1 - Figure 2 shown, the present utility model further includes a first fixing member 5. The first fixing member 5 is respectively connected to the fixing portion 221 and the support portion 211, making the connection between the fixing portion 221 and the support portion 211 more stable, and at the same time ensuring that the embedded waterstop 3 can be clamped more tightly by the fixing portion 221 and the support portion 211, thereby improving the stability and the effect of the embedded waterstop 3.

[0053] More specifically, the first fixing member 5 is rod-shaped and extends vertically, and the bottom end abuts against the reference plane. At this time, the first fixing member 5 can support the fixing portion 221 and the support portion 211, so that the fixing portion 221 and the support portion 211 are more stable, and further ensure that the embedded waterstop 3 is horizontally straight, making the installation quality of the embedded waterstop 3 higher, and the waterstop effect of the embedded waterstop 3 is better exerted.

[0054] Specifically, the adjustable lining trolley end template further includes a second fixing member 6. The second fixing member 6 is respectively connected to the template adjusting block 4 and the end template 2, making the connection between the template adjusting block 4 and the end template 2 more stable.

[0055] Specifically, the adjustable end formwork of the lining trolley further includes a reinforcement ring cross brace 7 and a reinforcement ring 8. One end of the reinforcement ring cross brace 7 abuts against the bottom connection block 1, the other end of the reinforcement ring cross brace 7 is connected to one end of the reinforcement ring 8, and the other end of the reinforcement ring 8 is connected to the reference plane, enabling the adjustable end formwork assembly of the lining trolley to be firmly connected to the end of the lining trolley 1000.

[0056] Specifically, the adjustable end formwork of the lining trolley further includes a diagonal brace 9. One end of the diagonal brace 9 abuts against the end formwork 2, and the other end of the diagonal brace 9 abuts against the reference plane, for supporting the end formwork 2 to make the end formwork 2 more stable. In this embodiment, the diagonal brace 9 is a telescopic rod. Even if the lining thickness changes, by stretching or contracting the diagonal brace 9, the abutment and support of the end formwork 2 can be achieved, reducing the cost of manually replacing the diagonal brace 9.

[0057] In this embodiment, the adjustable end formwork assembly of the lining is mainly made of steel, so that it is not affected by the environment during storage and can be recycled.

[0058] In this embodiment, the installation steps of the adjustable end formwork of the lining trolley are as follows:

[0059] First, the lower ring formwork 21 and the upper ring formwork 22 are rotationally connected by a pin shaft, and the upper ring formwork 22 and the formwork adjusting block 4 (if the lining thickness is required) are fixed by a pin shaft.

[0060] Then, the lining trolley 1000 is in place, the bottom connection block 1 is fixedly connected to the lining trolley 1000, then one end of the reinforcement ring cross brace 7 is connected to the bottom connection block 1, the other end is connected to the reinforcement ring 8, and the other end of the reinforcement ring 8 is connected to the lining trolley 1000.

[0061] Then, install the end formwork 2, and fixedly connect the lower ring formwork 21 and the bottom connection block 1 with a pin shaft.

[0062] Next, install the embedded waterstop 3 on the support portion 211 of the lower ring formwork 21, flip the upper ring formwork 22, and clamp the embedded waterstop 3 between the fixing portion 221 and the support portion 211. At this time, fix the upper ring formwork 22 and the lower ring formwork 21 with a pin shaft.

[0063] Immediately afterwards, install the second fixing member 6 to fix the formwork adjusting block 4 and the end formwork 2, and then install the first fixing member 5 to fix the upper ring formwork 22 and the lower ring formwork 21.

[0064] Finally, install the diagonal brace 9.

[0065] After the lining concrete is poured, the removal is carried out in the order of installing first and removing later, and installing later and removing first. Among them, the embedded waterstop 3, the bottom connection block 1, the reinforcement ring cross brace 7 and the reinforcement ring 8 do not need to be removed. When the end formwork 2 does not need to be changed, the lower ring formwork 21, the upper ring formwork 22 and the formwork adjustment block 4 are also not removed, and only the pin fixing needs to be cancelled. The whole installation and disassembly process is simple and convenient, and the labor cost is low.

[0066] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
