[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] Embodiment 1

[0031] like Figure 1 to Figure 2As shown, an integral pull-out TBM invert block core mold described in an embodiment of the present invention comprises an invert block core mold 1; a bottom membrane 11 is fixedly connected to the bottom surface of the invert block core mold 1; a No. 1 slide groove 12 is penetrated through the top surface of the bottom membrane 11 at the four corners; a plurality of groups of No. 1 slide grooves 12 are slidably connected to the inside thereof; during operation, in the tunnel construction stage, as the excavation depth continues to increase, in order to protect the tunnel safety, it is often necessary to gradually lay invert blocks, disperse the force of the supporting structure above the tunnel to both sides, and at the same time effectively resist the reaction force from the lower stratum of the tunnel. The existing invert is often a reinforced concrete structure, and the staff inside the tunnel first dig a downward ditch of sufficient depth, and first align the plurality of groups of positioning rods 13. The positions of the inverted arch block core mold 1 and the bottom membrane 11 are determined, and the inverted arch block core mold 1 is moved by the lifting equipment. At this time, the bottom membrane 11 installed on the bottom of the inverted arch block core mold 1 can allow the positioning rod 13 to pass through the No. 1 slide groove 12 opened on its four corners, so that the inverted arch block core mold 1 is accurately placed at the predetermined position, and then this step is repeated to install multiple groups of inverted arch block core molds 1 to provide support for subsequent concrete pouring. The position is determined in advance by using multiple groups of positioning rods 13, which can facilitate the subsequent installation and placement of the inverted arch block core mold 1. At the same time, the connection method of bolts and buckles is omitted, the time during assembly is reduced, and the work efficiency is increased. At the same time, the position adjustment of the positioning rod 13 is more convenient than adjusting the inverted arch block core mold 1 as a whole.

[0032] like Figure 4As shown, the side wall of the positioning rod 13 is located below the bottom film 11 and is provided with a pair of No. 2 slide grooves 2 relative to the position; the No. 2 slide groove 2 is slidably connected with an extrusion rod 21; the No. 2 slide groove 2 and the extrusion rod 21 are connected by a spring; the side wall of the positioning rod 13 is located above the No. 1 slide groove 12 after the No. 1 slide groove 12 is fitted; a pair of limit blocks 23 are slidably connected inside the No. 3 slide groove 22; a pair of the limit blocks 23 are connected by an elastic rope; the middle part of the No. 3 slide groove 22 is slidably connected with the limit block 23; the extrusion plate 24 and the extrusion rod 21 are connected by a linkage rod 25; the central axis of the linkage rod 25 is hinged on the inner side wall of the positioning rod 13; during operation, when the staff drives the arch block core mold 1 to move, the arch block core mold 1 will drive the bottom film 11 to move to Just above the positioning rod 13, as the inverted arch block core mold 1 descends, the positioning rod 13 gradually passes through the No. 1 slide groove 12. During the continuous descending process of the inverted arch block core mold 1, the extrusion rod 21 will be squeezed to move the extrusion rod 21 downward, driving the linkage rod 25 to move along the central axis, so that the other end of the linkage rod 25 drives the extrusion plate 24 to rise upward, and pushes the ends of a pair of limit blocks 23 to move the limit blocks 23 outward to block the No. 1 slide groove 12, restricting the bottom membrane 11 from moving upward, and keeping it stable during concrete pouring. The blocking of the bottom membrane 11 by the limit blocks 23 can provide strong support for the pouring of concrete after the inverted arch block core mold 1 is assembled, reduce the quality problems such as bubbles, joints, and leakage during concrete pouring, and provide a stable foundation for subsequent tunnel construction and vehicle traffic.

[0033] like Figure 5 As shown, a fourth slide slot 31 is provided at the bottom of the limit block 23; a support plate 3 is hingedly connected to the side wall of the fourth slide slot 31 away from the extrusion plate 24; the support plate 3 and the fourth slide slot 31 are connected by a torsion spring; one end of a support rod 32 is hingedly connected to the side wall of the support plate 3 and the top of the fourth slide slot 31; the support rods 32 are a pair and are connected by a torsion spring; when working, when the limit block 23 moves out of the third slide slot 22 under the extrusion of the extrusion plate 24, the support plate 3 moves under the torsion force of the torsion spring after there is no shielding from the third slide slot 22 The support plate 3 rotates downward, and at the same time, a pair of support rods 32 assist the support plate 3 to rotate under the action of the torsion spring, so that the angle between the pair of support plates 3 changes to 180 degrees. At the same time, the support plate 3 vertically downward contacts the top surface of the bottom membrane 11. The rotation of the support plate 3 can fill the gap between the limit block 23 and the bottom membrane 11, and further reduce the shaking caused by the gap between the bottom membrane 11 and the limit block 23, thereby affecting the appearance of bubbles and voids in the subsequent concrete filling process, thereby affecting the quality and leaving safety hazards for tunnel construction.

[0034] like Figure 3As shown, No. 5 slide grooves 4 are provided at corresponding positions on both sides of the No. 1 slide groove 12; a connecting block 41 is slidably connected inside the No. 5 slide groove 4; the connecting block 41 is rotatably connected to the end of the positioning rod 13 with a rotating shaft; multiple groups of No. 6 slide grooves 42 are provided on both sides of the positioning rod 13; during operation, when the bottom film 11 is located above the positioning rod 13 and slides, the connecting block 41 contacts the side wall of the positioning rod 13 under the action of the spring. At this time, the No. 6 slide groove 42 provided on the side wall of the positioning rod 13 can allow the connecting block 41 to enter, so that a collision effect is generated during the movement of the connecting block 41, causing a sound, and the downward movement of the bottom film 11 can drive the connecting block 41 and the No. 6 slide groove 42 to collide, so that the bottom film 11 produces a sound during the movement, reminding the staff of the position of the bottom film 11, reducing the deviation of the bottom film 11 during the installation process, and at the same time using sound to remind the staff that the bottom film 11 is in the installation process, increasing the construction safety of the staff.

[0035] like Figure 3 As shown, the positioning rod 13 is provided with a seventh slide groove 5 inside; a connecting rope 51 is fixedly connected to the top of the seventh slide groove 5; a plurality of groups of impact balls 52 are fixedly connected to the middle of the connecting rope 51; a first magnet 53 is fixedly connected to the inside of the impact ball 52; a second magnet 54 is fixedly connected to the inside of the connecting block 41; the first magnet 53 and the second magnet 54 are magnetically attracted to each other; during operation, during the movement of the bottom film 11, as the bottom film 11 continues to move downward, the magnetic attraction effect between the first magnet 53 and the second magnet 54 mobilizes the impact ball 52 to move left and right Movement, after one pair of the impact balls 52 leaves the range of the second magnet 54, the pair of impact balls 52 approach each other and collide with each other, and the magnetic attraction between the first magnet 53 and the second magnet 54 can be used to make the pair of impact balls 52 collide with each other during the movement of the bottom membrane 11 to produce a sound, and the sound of the movement of the connecting block 41 can further remind the staff that the bottom membrane 11 is in the process of installation, thereby reducing the problem of injuries caused by the staff not paying attention to the position of the bottom membrane 11 and colliding with the bottom membrane 11, thereby improving construction safety.

[0036] like Figure 3As shown, the bottom surface of the bottom membrane 11 is provided with guide grooves 6 on both sides of the No. 1 slide groove 12; the side walls of the guide grooves 6 are fixedly connected with rubber plates 61; the rubber plates 61 are in contact with the side walls of the positioning rods 13, and the rubber plates 61 are arc-shaped and bent upward; during operation, when the bottom membrane 11 is installed and fixed, the rubber plates 61 provided on the bottom surface of the bottom membrane 11 can assist the positioning rods 13 in installation, and at the same time, the rubber plates 61 installed on the side walls of the guide grooves 6 can contact the side walls of the No. 6 slide grooves 42 during the downward movement of the bottom membrane 11, and fill the gap between the No. 1 slide groove 12 and the positioning rods 13 according to the continuous descent of the bottom membrane 11, and utilize the guide grooves 6 provided on the ground of the bottom membrane 11, in conjunction with the rubber plates 61, to fill the gap between the No. 1 slide groove 12 and the positioning rods 13 during the movement of the bottom membrane 11, thereby increasing the stability of the bottom membrane 11 during the subsequent concrete filling process and reducing the possibility of shaking.

[0037] like Figure 6 As shown, the side wall where the rubber plate 61 and the positioning rod 13 are in contact is provided with a No. 8 slide groove 7; the No. 8 slide grooves 7 are multiple groups and are evenly arranged; the multiple groups of No. 8 slide grooves 7 are fixedly connected with suction cups 71 inside; during operation, after the rubber plate 61 and the positioning rod 13 are in contact, the bottom film 11 continues to drop, which will cause the contact area between the rubber plate 61 and the positioning rod 13 to increase continuously, and at this time, the suction cup 71 installed on the side wall of the rubber plate 61 can be adsorbed on the side wall of the positioning rod 13, and the suction cup 71 installed on the side wall of the rubber plate 61 can be used to further assist the rubber plate 61 to fit on the side wall of the positioning rod 13, thereby increasing the fixing effect and reducing the shaking of the bottom film 11.

[0038] like Figure 6 As shown, the side wall of the guide groove 6 is fixedly connected with a cleaning plate 8; the rubber plate 61 slides in the middle of the cleaning plate 8; the cleaning plate 8 is provided with a No. 9 slide groove 81 at the contact position with the rubber plate 61; the No. 9 slide groove 81 is slidably connected with a brush 82; the brush 82 and the No. 9 slide groove 81 are connected by a spring; the brush 82 is in contact with the side wall of the rubber plate 61; when working, the rubber plate 61 will move on the cleaning plate 8 during movement, and at this time, the brush 82 will contact the side wall of the rubber plate 61 under the action of the spring, and scrape and clean the suction cup 71 installed inside the No. 8 slide groove 7, and the auxiliary rubber plate 61 is attached to the side wall of the positioning rod 13. The contact between the brush 82 and the rubber plate 61 can reduce the adhesion of dust and impurities on the suction cup 71, further improve the adsorption effect after the rubber plate 61 and the positioning rod 13 are in contact, strengthen the fixing effect, and reduce the shaking of the bottom film 11.

[0039] like Figure 6As shown, the middle part of the cleaning plate 8 and the side wall in contact with the rubber plate 61 are rotatably connected with a cam 9; during operation, during the movement of the rubber plate 61, the cam 9 rotates during the contact with the rubber plate 61, causing the rubber plate 61 to jump, thereby increasing the contact between the rubber plate 61 and the brush 82. The rotation of the cam 9 can increase the contact between the rubber plate 61 and the brush 82, further improving the cleaning effect of the suction cup 71 and reducing the adhesion of impurities on the suction cup 71.

[0040] Embodiment 2

[0041] like Figure 7 As shown, compared with Example 1, another implementation of the present invention is: the top side wall of the extrusion plate 24 is rotatably connected to a pair of rollers 101; the rollers 101 are in contact with the ends of the limit blocks 23; during operation, when the extrusion plate 24 is pushed by the linkage rod 25, the rollers 101 installed on the top thereof utilize their own rotation to contact the ends of the limit blocks 23, and assist the limit blocks 23 to be pushed outward. The self-rotatability of the rollers 101 can assist the limit blocks 23 to be pushed out smoothly, thereby reducing the occurrence of jams and improving the stability of the equipment during operation.

[0042] During the tunnel construction phase, as the excavation depth continues to increase, in order to protect the safety of the tunnel, it is often necessary to gradually lay inverted arch blocks to disperse the force on the supporting structure above the tunnel to both sides, and at the same time effectively resist the reaction force from the lower stratum of the tunnel. The existing inverted arch is often a reinforced concrete structure. The tunnel internal workers first dig a downward ditch of sufficient depth, and first fix multiple groups of positioning rods 13 to determine the positions of the inverted arch block core mold 1 and the bottom membrane 11. Then, the inverted arch block core mold 1 is moved by the lifting equipment. At this time, the bottom membrane 11 installed on the bottom of the inverted arch block core mold 1 can allow the positioning rod 13 to pass through the No. 1 slide groove 12 opened on its four corners, so that the inverted arch block core mold 1 is accurately placed in the predetermined position. Repeat this step to install multiple sets of inverted arch block core molds 1 to provide support for subsequent concrete pouring. When the staff drives the inverted arch block core mold 1 to move, the inverted arch block core mold 1 will drive the bottom membrane 11 to move to just above the positioning rod 13. As the inverted arch block core mold 1 descends, the positioning rod 13 gradually passes through the No. 1 slide groove 12. During the continuous descending process of the inverted arch block core mold 1, the extrusion rod 21 will be squeezed to move the extrusion rod 21 downward, driving the linkage rod 25 to move along the central axis, so that the other end of the linkage rod 25 drives the extrusion plate 24 to rise upward, push the ends of a pair of limit blocks 23, so that the limit blocks 23 move outward, block the No. 1 slide groove 12, and limit the bottom membrane 11 so that it cannot move upward, so as to ensure that the bottom membrane 11 can be placed in the concrete pouring state. The support plate 3 rotates downward under the torsion force of the torsion spring after the limit block 23 moves out of the No. 3 slide groove 22 under the extrusion of the extrusion plate 24, and at the same time, a pair of support rods 32 assist the support plate 3 to rotate under the action of the torsion spring, so that the angle between the pair of support plates 3 changes to 180 degrees. At the same time, the support plate 3 vertically downward contacts the top surface of the bottom film 11. When the bottom film 11 slides above the positioning rod 13, the connecting block 41 contacts the side wall of the positioning rod 13 under the action of the spring. At this time, the No. 6 slide groove 42 opened on the side wall of the positioning rod 13 can allow the connecting block 41 to enter, so that a collision effect is generated during the movement of the connecting block 41, causing a sound. During the movement of the bottom film 11, as the bottom film 11 continues to move, The bottom film 11 moves downward, so that the magnetic attraction effect between the No. 1 magnet 53 and the No. 2 magnet 54 mobilizes the impact ball 52 to move left and right. After a pair of impact balls 52 leave the range of the No. 2 magnet 54, the pair of impact balls 52 approach each other and collide. When the bottom film 11 is installed and fixed, the rubber plate 61 opened on the bottom surface of the bottom film 11 can assist the installation of the positioning rod 13. At the same time, the rubber plate 61 installed on the side wall of the guide groove 6 can contact the side wall of the No. 6 slide groove 42 during the downward movement of the bottom film 11, and fill the gap between the No. 1 slide groove 12 and the positioning rod 13 according to the continuous descent of the bottom film 11. After the rubber plate 61 and the positioning rod 13 are in contact, the bottom film 11 continues to descend, which will increase the contact area between the rubber plate 61 and the positioning rod 13.At this time, the suction cup 71 installed on the side wall of the rubber plate 61 can be adsorbed on the side wall of the positioning rod 13. The rubber plate 61 will move on the cleaning plate 8 during movement. At this time, the brush 82 will contact the side wall of the rubber plate 61 under the action of the spring, and scrape and clean the suction cup 71 installed inside the No. 8 slide 7, and assist the rubber plate 61 to fit on the side wall of the positioning rod 13. During the movement of the rubber plate 61, the cam 9 will rotate during the contact process with the rubber plate 61, causing the rubber plate 61 to jump, so that the contact between the rubber plate 61 and the brush 82 is increased.
