Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, and more specifically, to a flip plug board based on a tunnel secondary lining trolley and its steel-wood combined construction framework. Background Technique

[0002] At present, in the construction process of highway engineering for tunnel composite lining, a new lining trolley is usually used for concrete pouring construction of the secondary lining, and a plug board is often required to cooperate for lateral sealing at the side position of the pouring area between the trolley and the tunnel surface. Traditional plug boards generally use several narrow wooden strips for plugging. However, in actual application, due to too many joints of the traditional plug board, phenomena such as slurry leakage are likely to occur.

[0003] At the same time, since the wooden strip cannot be disconnected from the middle, when installing the embedded water stop belt, the water stop belt needs to be bent and attached to the inner side of the plug board, and then pried out after the concrete is poured and the formwork is removed. However, in the on-site implementation process, first, the water stop belt cannot be effectively fixed, and the water stop belt is likely to be displaced during the concrete pouring process, thus reducing the waterproof effect of the water stop belt. Second, the process of prying out the water stop belt will cause damage to the water stop belt.

[0004] In view of the above situation, some manufacturers have proposed steel plug boards. However, due to the poor flatness of the surface of the initial support formed by excavation and the large stiffness of the steel plug board, it is difficult to adjust during the adaptation process, and it is difficult to fit and seal tightly with the surface of the initial support, resulting in a reduction in the quality and efficiency of the secondary lining construction. Content of the Utility Model

[0048] As Figures 1 to 4 shown, the embodiment of the present utility model provides a flip - type plug - head plate and its steel - wood combination construction framework based on a tunnel secondary lining trolley. The flip - type plug - head plate includes a hinged base 1, a first rotating arm and a plug - head plate assembly 2, a second rotating arm 3 and a second plug - head plate 4. By means of two hinges and two sets of plug - head plates, on the basis of effectively realizing the established plugging function, it can also respectively control the relative flipping and opening of the two sets of plug - head plates, thereby effectively improving the convenience of installation and removal of the plug - head plate and the operation efficiency. At the same time, the waterstop assembly interval 5 formed by the two sets of plug - head plates is more convenient for the installation and removal of the waterstop, thus effectively saving the overall installation time of the plug - head plate framework, and further effectively controlling the installation quality of the embedded waterstop, ensuring that the plug - head plate is tightly embedded and sealed with the primary support surface to prevent slurry leakage. In addition, the hinged base 1 can be used to adjust the extension length of the framework according to different lining thicknesses based on the lining trolley a, significantly improving the functional adaptability and practicality of the overall framework, and having good popularization and application value. The specific settings are as follows:

At the same time, a local plug - head plate structure can be effectively formed after the first rotating arm and the plug - head plate assembly 2 are rotated.

[0050] One end of the second rotating arm 3 is connected and assembled in a transfer manner to the other end of the first rotating arm and the plug - head plate assembly 2, and the other end of the second rotating arm 3 is fixedly assembled with a second plug - head plate 4. The second rotating arm 3 and the second plug - head plate 4 can be further rotated based on the first rotating arm and the plug - head plate assembly 2, and the second plug - head plate 4 can be set to be flush with the first plug - head plate in the first rotating arm and the plug - head plate assembly 2 after rotation, so as to drive the two sets of plug - head plates to remain flush with each other based on the rotation of the two hinges, thereby effectively realizing the established plugging function. At the same time, the two sets of plug - head plates can be further respectively driven to perform relative flipping and opening, effectively improving the convenience of installation and removal and the operation efficiency.

[0051] When the first plug board in the first indexing arm and the plug board assembly 2 is flush with the second plug board 4 after indexing, a water stop belt assembly interval 5 is formed between them, which is used to facilitate the disassembly and assembly of the water stop belt through the water stop belt assembly interval 5. Thus, the overall installation time of the plug board construction framework is saved, and at the same time, the installation quality of the embedded water stop belt can be further effectively controlled, improving the functional practicability.

[0052] Please refer to Figure 1 and Figure 2 As shown in, the steel-wood combined construction framework includes the above-mentioned flip-type plug board based on the tunnel secondary lining trolley, as well as a first support plate 6, a first limiting rod 7, a limiting cushion block 8, a second support plate 9, a second limiting rod 10, a plug wooden strip 11 and a limiting wooden wedge 12; specifically, the first support plate 6 is fixedly assembled on the first indexing arm and the plug board assembly 2, and the first limiting rod 7 is inserted through the first support plate 6 to form a lever structure with the first support plate 6 as the fulcrum; the lining trolley a forms a supporting force x acting on one end of the first limiting rod 7 through a transmission member, and the other end of the first limiting rod 7 touches and presses on the back side of the first plug board of the first indexing arm and the plug board assembly 2 through the limiting cushion block 8, so as to effectively transmit the supporting force x to the first plug board through the lever action and the fulcrum formed by the first support plate 6, and further keep the first indexing arm and the plug board assembly 2 stable.

[0053] The second support plate 9 is fixedly assembled on the first indexing arm and the plug board assembly 2, the second limiting rod 10 sequentially passes through the first support plate 6 and the second support plate 9, and the second limiting rod 10 extends and touches and presses on the second indexing arm 3, so as to further stably limit the second indexing arm 3 and the second plug board 4 based on the first indexing arm and the plug board assembly 2 through the second limiting rod 10.

[0054] As a preferred solution of this embodiment, please continue to refer to Figure 1 As shown in, a plug wooden strip 11 is further provided on the back side of the position where the second plug board 4 corresponds to the gap between the initial support surface b, the plug wooden strip 11 is correspondingly arranged with the second limiting rod 10, and a limiting wooden wedge 12 is firmly embedded between the plug wooden strip 11 and the second limiting rod 10, so as to further firmly block the plug wooden strip 11 at the edge gap position through the limiting wooden wedge 12 based on the limiting action of the second limiting rod 10.
