Description

Technical Field

[0001] The utility model belongs to the technical field of tunnel construction and provides a movable end template for positioning an embedded waterstop belt, which improves positioning accuracy and effectively ensures waterproofness. Background Art

[0002] In tunnel construction, there is a considerable amount of underground water, so the construction of tunnel waterproofing and drainage is particularly important during the tunnel construction process, especially the installation and positioning of the embedded waterstop. The embedded waterstop is installed in the middle of the secondary lining, but the existing conventional second-village formwork trolley end formwork cannot accurately position and fix the embedded waterstop. Workers are required to first lay out the lines and adjust the formwork when supporting the structural formwork, and then use special clamps, wire pulling method or formwork fixing method and other conventional methods to fix it. The existing positioning and fixing construction process of the embedded waterstop results in poor positioning accuracy, which is easy to damage the embedded waterstop and cause hidden dangers in the later waterproofing. Utility Model Content

[0003] In view of this, the purpose of the present invention is to provide a movable end template for positioning an embedded waterstop, which improves positioning accuracy and effectively ensures waterproofness.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0005] The utility model provides a movable end template for positioning an embedded waterstop, which comprises a secondary lining template trolley body, and at least one set of steel mold turning connection mechanisms fixed on the secondary lining template trolley body;

[0006] The steel mold turnover connection mechanism is fixed to the steel mold plate as a whole. Under the action of external force, the steel mold plate is turned over on the secondary lining mold plate trolley body under the action of the steel mold turnover connection mechanism.

[0007] A left snap ring and a right snap ring are fixed to the top plate of the steel template, and there are at least two right snap rings. The number of the left snap rings is the same as that of the right snap rings, and the axis of the left snap ring and the axis of the right snap ring are on the same straight line.

[0008] The supporting steel pipe passing through the left clamping ring and the right clamping ring is located on the square wood, and the square wood is fixed on the wooden formwork for the secondary lining concrete.

[0009] In order to make the steel mold flip connection mechanism simple in structure, easy to manufacture and operate, the above scheme further: the steel mold flip connection mechanism includes a sleeve welded as one body to the second lining template trolley body, an L-shaped pin welded as one body to the steel template at one end, and the other end of the L-shaped pin passes through the sleeve and is limited by a limit nut threadedly connected to it.

[0016] The present invention is further described below in conjunction with specific embodiments. The accompanying drawings are for illustrative purposes only and are schematic, not actual, representations. They should not be construed as limiting this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted from the drawings.

[0017] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0018] The present invention will be described in further detail below with reference to the accompanying drawings.

[0019] like Figure 1-2As shown, the utility model provides a movable end template for positioning a buried waterstop, which includes: a secondary lining template trolley body 1, at least one set of steel mold flip connection mechanism 2 fixed on the secondary lining template trolley body 1;

[0020] The steel mold turnover connection mechanism 2 is fixed to the steel mold plate 3 as a whole. Under the action of external force, the steel mold plate 3 is flipped on the secondary lining mold plate trolley body 1 under the action of the steel mold turnover connection mechanism 2;

[0021] A left snap ring 4 and a right snap ring 5 are fixed to the top plate surface of the steel template 3. There are at least two right snap rings 5. The number of the left snap rings 4 is the same as the number of the right snap rings 5. The axis of the left snap ring 4 and the axis of the right snap ring 5 are on the same straight line.

[0022] The supporting steel pipe 6, after passing through the left and right snap rings 4 and 5, rests on a square timber 7, which is secured to the secondary concrete lining wooden formwork 8. In this embodiment, the steel formwork 3 is made of 1cm thick steel plate, with the left and right snap rings 4 and 5 welded to each. Each of these rings is 15cm high, 10cm wide, 1cm thick, and has a hole diameter of 5cm. The supporting steel pipe 6, used for fixing, is a φ42mm steel pipe. During use, an embedded waterstop 12 is located between the steel formwork 3 and the wooden formwork 8, effectively ensuring positioning accuracy.

[0023] In order to make the steel mold flip connection mechanism 2 simple in structure, easy to manufacture and operate, in the above embodiment, preferably: the steel mold flip connection mechanism 2 includes a sleeve 9 welded as one body with the second lining template trolley body 1, and an L-shaped pin 10 welded as one body with the steel template 3 at one end, and the other end of the L-shaped pin 10 passes through the sleeve 9 and is limited by a limiting nut 11 threadedly connected to it.

[0024] The relevant components in all the above embodiments are conventional products sold on the market.

[0025] See attached Figures 1 to 3 , the construction process of the structure of the utility model is as follows:

[0026] The embedded waterstop 12 can be accurately positioned by using the half-movable steel formwork 3. The steel formwork 3 can just make the embedded waterstop 12 be located in the middle of the second lining concrete layer 13. The other half end is sealed with the second lining concrete wooden formwork 8. After sealing, the support steel pipe 6 inserted into the left clamping ring 4 and the right clamping ring 5 of the steel formwork 3 is used for fixing and limiting, so as to achieve the conditions for pouring concrete of the second lining concrete layer 13. After the concrete strength reaches the requirement, the support steel pipe 6 is first removed, and then the second lining concrete wooden formwork 8 is removed. Finally, the steel formwork 3 is turned over, and the second lining trolley is pushed forward to construct the next section of the second lining concrete layer 13. This can greatly improve the position accuracy of the embedded waterstop and ensure that the embedded waterstop is not damaged, which has great advantages for its subsequent waterproofing effect. Appendix Figure 3 In the embodiment, the initial support layer 14 is constructed before the embedded water stop 12 is installed.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
