[0065] To make the technical means, inventive features, objectives, and effects of this utility model readily understandable, the technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0066] In summary, a more specific embodiment of this utility model is as follows:

[0067] Before using the tunnel invert end filling support component of the above-mentioned design structure, it needs to be manufactured and installed as a backup.

[0068] Example 1

[0069] As per the instruction manual Figures 1 to 9 As shown, a tunnel invert end filling support assembly includes:

[0070] The first baffle (1) has a first base plate (2) that is adapted to the corresponding side arch (10) extending to the bottom of the first baffle (1). Multiple first base plate fixing holes (21) are provided through the first base plate (2).

[0071] The second baffle (3) has a second base plate (4) that is adapted to the corresponding side arch (10) extending to the bottom of the second baffle (3). Several second base plate fixing holes (41) are provided through the second base plate (4).

[0072] Multiple adjustable support members (5) are rotatably connected to the first baffle (1) and the second baffle (3), respectively;

[0073] Fixing member (6) passes through the first base plate fixing hole (21) and the second base plate fixing hole (41) respectively and is fixed on the ground;

[0074] Among them, the first baffle (1) and the second baffle (3) are assembled to seal the filling end of the tunnel invert arch (10).

[0075] In this utility model, the side back rib at the bottom of the first baffle (1) is fixedly connected to the first base plate (2) or is processed into an integral structure;

[0076] The bottom edge of the second baffle (3) is fixedly connected to the second base plate (4) or is processed into an integral structure.

[0077] In this utility model, the first baffle (1) and the second baffle (3) are both made of 8mm thick steel plates according to the corresponding side arch filling size to make the main template. 8mm thick 10cm wide steel plates are used as the back ribs around the template, and 8mm thick 5cm wide steel plates are used as the horizontal and vertical back ribs (30cm apart). They are welded together to form a whole.

[0078] Furthermore, it also includes several hanging rings (7) respectively connected to the top of the first baffle (1) and the second baffle (3).

[0079] In this utility model, the lifting ring (7) serves as the connection point of the lifting equipment, which facilitates transportation and installation through the lifting equipment and avoids lifting instability or baffle tilt caused by improper lifting points.

[0080] Furthermore, it also includes several connectors (8) for securely connecting the overlapping ends of the first baffle (1) and the second baffle (3) into one unit.

[0081] Specifically, the connectors (8) are vertically connected to the overlapping ends of the second baffle (3);

[0082] The first baffle (1) has a through hole (11) on the side back rib of the overlapping end that is adapted to the connector (8).

[0083] In this utility model, the connector (8) is not limited to being installed on the second baffle (3). It can be installed on the first baffle (1) and / or the second baffle (3). It only needs to have a connection hole provided on the other baffle that does not have the connector (8) installed to complete the connection work.

[0084] Specifically, the connector (8) includes:

[0085] Mounting base (81), mounting base (81) is arranged opposite to each other on the second baffle (3);

[0086] Pin (82) is slidably connected to two mounting bases (81);

[0087] Among them, the pin (82) is used to pass through the side back rib of the overlapping end of the second baffle (3) and connect with the corresponding connection hole (11) of the first baffle (1).

[0088] Preferably, the pin (82) is in the shape of a "T"; furthermore, a limiting block is provided on the second baffle (3) between the two mounting seats (81) to limit the movement of the pin (82) after the connection is completed; after the pin (82) passes through the second baffle (3) and connects to the connection hole (11) of the first baffle (1), it prevents the pin (82) from moving laterally, which would lead to an unstable connection. The specific connection steps of the connector (8) are as follows: After the overlapping ends of the first baffle (1) and the second baffle (3) are together, pinch the vertical end of the pin (82), rotate the pin (82) upward so that the vertical end of the pin (82) is perpendicular to the second baffle (3), then move the pin (82) towards the connection hole (11) of the first baffle (1) until the horizontal end of the pin (82) is inserted into the connection hole (11), and then rotate the vertical end of the pin (82) downward so that the vertical end of the pin (82) is located between the limiting block and the mounting seat (81) near the end of the first baffle (1), thus completing the connection of the connector (8).

[0089] Furthermore, the adjustable support (5) includes:

[0090] Connecting seat (51), one end of which is connected to the first baffle (1) or the second baffle (3);

[0091] Support member (52), one end of which is rotatably connected to connecting seat (51);

[0092] The fixed base (53) is rotatably connected to the other end of the support (52) for contacting the ground;

[0093] Among them, the support member (52) has telescopic adjustment function and length locking function.

[0094] In this utility model, the support member (52) is a hydraulic rod; the fixed seat (53) is also provided with several fixing holes, which can be used to fix it to the unexcavated solid inverted rock mass by locking the locking member, so as to ensure the support stability of the adjustable support member (5).

[0095] Furthermore, one end of the fastener (6) is tapered.

[0096] In this utility model, the fixing member (6) is a steel bar with a cone shape at one end. The cone shape makes it easy to pass through the fixing hole of the bottom plate and fix it to the ground. The rib-shaped texture on the outside of the steel bar can increase the friction between the steel bar and the ground, prevent the steel bar from slipping in the ground, thereby improving the fixing effect and stability. At the same time, the rib-shaped texture on the outside also makes it easy to pull it out with tools.

[0097] Furthermore, it also includes a seal for sealing the gap between the first baffle (1) and the second baffle (3), and for sealing the gap between the two ends of the connecting baffle (9) and the first baffle (1) and the second baffle (3).

[0098] In this invention, the sealing element is a rubber sealing strip, a silicone sealing strip, or a cement-based sealant.

[0099] This embodiment is mainly used for filling at the end of an inverted arch without a central drainage ditch. The specific usage steps are as follows:

[0100] When in use, the operator lays out the center line of the tunnel invert arch filling and the elevation measurement, and then puts the wire rope of the hoisting equipment into the lifting ring (7) on the first baffle (1) and hoists it to the left side of the filling end of the tunnel invert arch (10). Then, the first bottom plate (2) at the bottom of the first baffle (1) is adjusted to a suitable position.

[0101] Then, the operator uses the lifting ring (7) connected to the second baffle (3) by the lifting equipment to lift it to the right side of the filling end of the tunnel arch (10). The operator adjusts the position of the second baffle (3) by the lifting equipment so that the left end of the second baffle (3) overlaps with the right end of the first baffle (1). After the position is adjusted, the pin (82) of the connector (8) is inserted into the corresponding connecting hole (11) to complete the connection between the first baffle (1) and the second baffle (3).

[0102] Next, the operator connects to the ground using multiple fasteners (6) that pass through the first base plate fixing hole (21) and the second base plate fixing hole (41);

[0103] Then, the operator adjusts the length of the support (52) on the adjustable support (5) so that the fixed seat (53) at the bottom of the support (52) abuts against the solid inverted rock mass that has not been excavated, ensuring that the air leg of the support is firmly fixed and is securely connected to the ground by the locking device;

[0104] Finally, the joint between the first baffle (1) and the second baffle (3) is sealed with a rubber sealing strip to prevent concrete leakage and water penetration. Afterward, concrete can be poured after applying a release agent to the surfaces of the first baffle (1) and the second baffle (3). After the filling concrete reaches the demolding strength, the formwork is removed with the help of an excavator, the formwork surface is cleaned and stacked neatly.

[0105] Example 2

[0106] As per the instruction manual Figures 10 to 17 As shown, this embodiment is basically the same as embodiment 1, except that it also includes a connecting baffle (9) set on the upper part between the first baffle (1) and the second baffle (3). Both ends of the connecting baffle (9) are connected to the baffles at the corresponding ends by locking parts (91).

[0107] Specifically, the shape and structure of the locking member (91) are the same as those of the connecting member (8); the pin of the locking member (91) is set through the side back rib of the end baffle;

[0108] The connecting baffle (9) has through-holes on the side back ribs at both ends, which are adapted to the corresponding locking parts (91).

[0109] This embodiment is mainly used for filling at the end of an inverted arch with a central water ditch. The specific usage steps are as follows:

[0110] When in use, the operator lays out the center line of the tunnel invert arch filling and the elevation measurement, and then puts the wire rope of the hoisting equipment into the lifting ring (7) on the first baffle (1) and hoists it to the left side of the central water ditch at the filling end of the tunnel invert arch (10). Then, the first bottom plate (2) at the bottom of the first baffle (1) is adjusted to a suitable position.

[0111] Then, the operator uses the lifting ring (7) connected to the second baffle (3) by the lifting equipment to lift it to the right side of the central water ditch at the filling end of the tunnel arch (10), and adjusts the position of the second baffle (3) by the lifting equipment.

[0112] Next, the connecting baffle (9) is moved to the upper part of the central water ditch. Then, the position of the connecting baffle (9) is adjusted so that the locking connection holes at both ends of the connecting baffle (9) are aligned with the corresponding locking parts (91). Then, the pins (82) of the locking parts (91) on both sides are inserted into the corresponding locking connection holes to complete the connection work between the first baffle (1), the second baffle (3), and the connecting baffle (9).

[0113] Next, the operator connects to the ground using multiple fasteners (6) that pass through the first base plate fixing hole (21) and the second base plate fixing hole (41);

[0114] Then, the operator adjusts the length of the support (52) on the adjustable support (5) so that the fixed seat (53) at the bottom of the support (52) abuts against the unexcavated solid inverted rock mass, ensuring that the air leg of the support is firmly fixed and is securely connected to the ground by the locking device;

[0115] Finally, seal the connection between the first baffle (1), the second baffle (3), the connecting baffle (9), and the central ditch with a sealant. After applying an isolation coating to the baffle surface, concrete can be poured. After the filling concrete reaches the demolding strength, use an excavator to remove the formwork, clean the formwork surface, and stack it neatly.

[0116] Finally, it should be noted that the concept, specific structure, and technical effects of this utility model have been clearly and completely described above in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model.
