Description
Technical Field
[0001] The present invention relates to the technical field of tunnel chamber construction, in particular to a tunnel chamber lining trolley and a lining casting trolley system provided with the tunnel chamber lining trolley. Background Art
[0002] In the construction of tunnel chamber lining projects, the chamber lining and the tunnel mainline lining intersecting with the chamber lining are usually constructed simultaneously. Figure 1 and Figure 2 As shown, the traditional construction method is: first, the main line lining trolley 91 is moved to the intersection of the chamber 92 and the tunnel main line 93, and the main line lining trolley 91 is positioned; then, the workers use small steel plates 94 to assemble the chamber formwork in the chamber 92, and use a simple bracket 95 made of I-beams to support and fix the chamber formwork. Among them, since the opening where the chamber lining and the tunnel main line lining intersect is an arc-shaped curved surface, it is difficult to overlap and assemble with the small steel plates 94. Therefore, the existing practice is to use a wooden formwork 96 instead of the small steel plate 94, so that the cut wooden formwork 96 meets the overlap and assembly requirements by cutting the wooden formwork 96; then, the concrete pouring construction of the chamber 92 and the tunnel main line lining is carried out.
[0003] It can be seen that the existing chamber formwork is temporarily made on site by workers, which makes it difficult to reuse. During the concrete pouring construction, the tunnel mainline lining and the chamber lining are often poured together, resulting in a large amount of concrete poured and a high pouring pressure, and the conditions for concrete vibration operation are not met. In addition, the chamber formwork often has problems such as deformation, mold running, and concrete leakage. Furthermore, since the chamber formwork is simply assembled, the joints of the small steel plates 94 seriously affect the smoothness of the surface of the chamber 92.
[0004] In summary, the existing construction methods are likely to cause defects in the chamber, such as loose concrete, insufficient strength, poor quality of the curved surface forming of the chamber lining, and poor concrete surface appearance, leaving major quality and safety risks for subsequent line operations and tunnel maintenance.

[0043] First embodiment of tunnel chamber lining trolley
[0044] Reference Figure 3 and Figure 4 The tunnel chamber lining trolley 100 is used to cooperate with the mainline lining trolley 101 to cast concrete for the tunnel mainline lining and the chamber lining. The tunnel chamber lining trolley 100 includes a vehicle body unit 1, a side form unit 2, a top form unit 3, an end form unit, and a telescopic support leg 5. There are two side form units 2, which are distributed on opposite sides of the vehicle body unit 1 along the width direction of the vehicle body unit 1. In this embodiment, the tunnel chamber lining trolley 100 can adjust its operating length according to the depth of the chamber lining, so that the tunnel chamber lining trolley 100 can assist in the construction of chambers of different depths, thereby improving the flexibility of the tunnel chamber lining trolley 100 and expanding the scope of application of the tunnel chamber lining trolley 100.
[0045] Specifically, the vehicle body unit 1 includes more than two vehicle bodies 11, which are distributed along the length direction of the vehicle body unit 1. A running wheel set is provided at the bottom of each vehicle body 11 to facilitate the movement of the tunnel chamber lining trolley 100.
[0046] The side formwork unit 2 includes a side form assembly 21, a first drive assembly 22, and a first support assembly. The side form assembly 21 includes two or more side formwork modules 211. The two or more side formwork modules 211 are distributed along the length of the vehicle body unit 1, and the two or more side formwork modules 211 correspond one-to-one with the two or more vehicle bodies 11. The side formwork module 211 at the head end of the side formwork module 21 is used to cooperate with the mainline lining trolley 101, and the side formwork module 211 at the end of the side formwork module 21 is used to cooperate with the end wall formwork unit 4. In order to ensure that the side form module 211 at the head end of the side form module 21 can closely cooperate with the main line lining trolley 101, an annular overlapping surface 2111 is formed at the first end of the side form module 21 at the head end of the side form module 21, so that when the tunnel chamber lining trolley 100 is docked with the main line lining trolley 101, the annular overlapping surface 2111 can fit tightly on the side form of the main line lining trolley 101.
[0047] The side mold assembly 211 includes a first arch top mold 2112, a first side mold 2113, and a first bottom mold 2114. In the circumferential direction of the tunnel chamber lining trolley 100, the two ends of the first side mold 2113 are hinged to the first arch top mold 2112 and the first bottom mold 2114, respectively, so that the first arch top mold 2112 and the first bottom mold 2114 can each rotate independently relative to the first side mold 2113. The circumferential overlap surface 2111 of the first end of the side mold assembly 211, located at the head end of the side mold assembly 21, is formed on the end faces of the first arch top mold 2112, the first side mold 2113, and the first bottom mold 2114 of the side mold assembly 211. The structural design of the side mold assembly 211 makes it easier to demold the side mold assembly 21 and enables the tunnel chamber lining trolley 100 to be more easily retracted and moved.
[0048] In the longitudinal direction of the vehicle body unit 1, any two adjacent side mold modules 211 are detachably connected. Preferably, an end plate 2215 is provided at the connection between a side mold module 211 and another side mold module 211, so that the two adjacent side mold modules 211 can be detachably connected through the end plate 2215. Figure 5 As shown, when two adjacent sets of side mold modules 211 need to be connected, the locking assembly 2119 can pass through the end plates 2215 of the two adjacent sets of side mold modules 211 to fix the two adjacent sets of side mold modules 211 together.
[0049] Combine Figure 6In order to ensure the airtightness when the tunnel chamber lining trolley 100 and the main line lining trolley 101 are docked, a first sealing strip 2116 is provided on the first end of the side mold group 21, and the first sealing strip 2116 protrudes from the annular overlapping surface 2111. As in the present embodiment, a first groove is provided at the first end of the side mold group 211 located at the head end of the side mold group 21, and the first groove is made to pass through the first end of the first arch top mold 2112, the first end of the first side mold 2113 and the first end of the first bottom mold 2114 of the side mold group 211 along the annular direction of the tunnel chamber lining trolley 100. The first sealing strip 2116 is provided in the first groove and protrudes from the annular overlapping surface 2111 of the side mold group 211. Figure 7 When the tunnel chamber lining trolley 100 is docked with the main line lining trolley 101, the first sealing strip 2116 will be squeezed and deformed, so that the annular overlapping surface 2111 of the side form module 211 at the head end of the side form module 21 can fit tightly on the side form of the main line lining trolley 101. The first sealing strip 2116 prevents the concrete from seeping into the tunnel chamber lining trolley 100 from the overlapping part between the tunnel chamber lining trolley 100 and the main line lining trolley 101 during the pouring of the chamber lining and the tunnel main line lining through its own deformation, thereby ensuring the pouring quality of the chamber lining and the tunnel main line lining.
[0050] Combine Figure 8 Furthermore, a third sealing strip 2117 is provided on the second end of the side form assembly 21. The third sealing strip 2117 is used to abut the end wall formwork unit 4 to ensure airtightness between the side formwork unit 2 and the end wall formwork unit 4. This prevents concrete from seeping into the interior of the tunnel chamber lining trolley 100 through the gap between the side formwork unit 2 and the end wall formwork unit 4 during the chamber lining pouring process, thereby ensuring the pouring quality of the chamber lining. In this embodiment, the third sealing strip 2117 is provided on the second end of a group of side form modules 211 located at the end of the side form assembly 21.
[0051] Furthermore, a fifth sealing strip 2118 is provided at the bottom of the side mold assembly 21, and the fifth sealing strip 2118 protrudes from the bottom surface of the side mold assembly 21. For example, in this embodiment, the bottom of the first bottom mold 2114 of each side mold assembly 211 is provided with a fifth sealing strip 2118, and the fifth sealing strip 2118 protrudes from the bottom surface of the first bottom mold 2114 (see FIG. Figure 4 The fifth sealing strip 2118 is used to prevent concrete from penetrating into the interior of the tunnel chamber lining trolley 100 through the gap between the side formwork module 211 and the ground during the chamber lining pouring process.
[0052] The first drive module 22 is connected between the side mold assembly 21 and the vehicle body unit 1 and is used to drive the side mold assembly 211 to move in the width direction. The first drive module 22 includes two or more first drive mechanisms 221, each corresponding to one or more vehicle bodies 11. Each first drive mechanism 221 is connected between a set of side mold assemblies 211 and a vehicle body 11. Preferably, the first drive mechanism 221 utilizes a first hydraulic cylinder connected between the vehicle body 11 and the first side mold 2113.
[0053] The first support module is connected between the side module 21 and the vehicle body unit 1 to support the side module 21 and prevent the side module 21 from shifting or deforming during the chamber lining pouring process, thereby ensuring the pouring quality of the chamber lining. The first support module includes two or more sets of first telescopic rods 231, which correspond one-to-one with the two or more vehicle bodies 11. Preferably, the first telescopic rod group 231 includes more than two first telescopic rods 2311 distributed along the length direction of the vehicle body unit 1 and more than two second telescopic rods 2312 distributed along the length direction of the vehicle body unit 1. The first telescopic rod 2311 and the second telescopic rod 2312 are preferably screw-type telescopic rods; the two ends of the first telescopic rod 2311 are respectively hinged to the vehicle body 11 and the first arch top mold 2112 to support and limit the first arch top mold 2112 to prevent the first arch top mold 2112 from rotating relative to the first side mold 2113 during the pouring of the chamber lining, thereby ensuring the pouring quality of the chamber lining; the two ends of the second telescopic rod 2312 are respectively hinged to the vehicle body 11 and the first bottom mold 2114 to support and limit the first bottom mold 2114 to prevent the first bottom from rotating relative to the first side mold 2113 during the pouring of the chamber lining, thereby ensuring the pouring quality of the chamber lining.
[0054] The top formwork unit 3 is mounted on top of the carbody unit 1 and positioned between the two side formwork units 2. It not only coordinates with the side formwork units 2 and end wall formwork units 4 to assist in forming the chamber lining, but also limits the position of the side formwork units 2 and end wall formwork units 4 to ensure the quality of the chamber lining. The top formwork unit 3 comprises a top mold assembly 31 and a second drive module 32. The second drive module 32 is connected between the top mold assembly 31 and the carbody unit 1 and is used to drive the top mold assembly 31 to move vertically along the height of the carbody unit 1.
[0055] The top mold assembly 31 includes two or more arch top molds 311, which are distributed along the length direction of the car body unit 1, and the two arch top molds 311 correspond one-to-one to the two or more car bodies 11. Among them, one arch top mold 311 located at the head end of the top mold assembly 31 is used to cooperate with the main line lining trolley 101, and one arch top mold 311 located at the end of the top mold assembly 31 is used to cooperate with the end wall mold unit 4. In order to ensure that the arch top mold 311 at the head end of the top mold assembly 31 can closely cooperate with the main line lining trolley 101, a matching overlap surface is formed at the first end of the arch top mold 311 located at the head end of the top mold assembly 31, so that when the tunnel chamber lining trolley 100 and the main line lining trolley 101 are docked, the matching overlap surface can closely fit on the side mold of the main line lining trolley 101. In addition, the cross-section of the arch top mold 311 is preferably roughly trapezoidal, and the first arch top mold 2112 of the side mold group 21 is inclined near one end face of the arch top mold 311, so that the first arch top mold 2112 can fit on the arch top mold 311.
[0056] Furthermore, to ensure airtightness during docking between the tunnel chamber lining trolley 100 and the mainline lining trolley 101, a second sealing strip is provided on the first end of the top mold assembly 31, protruding from the mating overlap surface. For example, in this embodiment, a second groove is provided at the first end of the dome top mold 311 at the head end of the top mold assembly 31, extending circumferentially through the first end of the dome top mold 311. The second sealing strip is disposed within the second groove and protrudes from the mating overlap surface of the dome top mold 311. Similarly, when the tunnel chamber lining trolley 100 is docked with the main line lining trolley 101, the second sealing strip will be squeezed and deformed, so that the mating overlapping surface of the arch top form 311 at the head end of the top form group 31 can fit tightly on the side form of the main line lining trolley 101. The second sealing strip prevents the concrete from seeping into the interior of the tunnel chamber lining trolley 100 from the overlapping part of the tunnel chamber lining trolley 100 and the main line lining trolley 101 during the pouring of the chamber lining and the tunnel main line lining through its own deformation, thereby ensuring the pouring quality of the chamber lining and the tunnel main line lining.
[0057] Furthermore, a fourth sealing strip is provided on the second end of the top formwork assembly 31. This fourth sealing strip is used to abut the end wall formwork unit 4 to ensure airtightness between the top formwork unit 3 and the end wall formwork unit 4. This prevents concrete from seeping into the interior of the tunnel chamber lining trolley 100 through the gap between the top formwork unit 3 and the end wall formwork unit 4 during the chamber lining pouring process, thereby ensuring the pouring quality of the chamber lining. In this embodiment, the fourth sealing strip is provided on the second end of a dome top formwork 311 located at the end of the side formwork assembly 21.
[0058] Any two adjacent arch top forms 311 are adjacent to each other in the length direction of the vehicle body unit 1. Preferably, a sealing gasket can be provided between the two adjacent arch top forms 311 to prevent concrete from seeping into the tunnel chamber lining trolley 100 through the gap between the two adjacent arch top forms 311 during the chamber lining pouring process.
[0059] The second drive module 32 includes two or more second drive mechanisms 321, each of which is connected between a dome top mold 311 and the vehicle body 11. The second drive mechanism 321 preferably includes two or more second hydraulic cylinders distributed along the length of the vehicle body unit 1, each of which is connected between the dome top mold 311 and the top of the vehicle body 11.
[0060] Combine Figure 9 The end wall mold unit 4 includes an end wall mold group 41 and a second support mold group 42. The end wall mold group 41 is located at the second end of the side mold group 211 and is used to form the end wall of the chamber. The second support mold group 42 is connected between the end wall mold group 41 and the vehicle body unit 1. Figure 3 and Figure 13 As shown), the side mold group 21, the top mold group 31 and the end wall mold group 41 are connected to form a shaping surface, so that the shaping surface can shape the contour of the chamber lining.
[0061] The end wall module 41 includes an end wall top module assembly, an end wall middle module assembly 412 and an end wall bottom module assembly 413, wherein in the height direction of the vehicle body unit 1, the two ends of the end wall middle module assembly 412 are hinged to the end wall top module assembly 411 and the end wall bottom module assembly 413 respectively. Preferably, the end wall top module assembly 411 includes two end wall top modules 4111 arranged in a mirror-symmetrical manner. In addition, an avoidance groove 4110 is provided in the middle of the end wall top module assembly 411. The cross section of the avoidance groove 4110 matches the cross section of the arch top module 311, and the avoidance groove 4110 passes through the two end wall top modules 4111 along the length direction of the vehicle body unit 1; the end wall middle module assembly 412 includes two end wall middle modules 4121 arranged in a mirror-symmetrical manner. The two end wall middle modules 4121 are connected by a hinge 415, so that the two end wall middle modules 4121 can pass through The hinge 415 rotates relative to each other, so that the end wall module 41 can be folded in half along its own symmetrical center line.

[0067] Combine Figures 11 to 13 The following is a brief description of the usage of the tunnel chamber lining trolley 100:
[0068] When the chamber lining pouring construction is to be carried out, the tunnel chamber lining trolley 100 is first moved into the chamber at the excavation site. At this time, the chamber has already undergone primary support concrete construction and chamber bottom construction.
[0069] Next, the tunnel chamber trolley is positioned by installing the surveying and setting out position, and the position of the vehicle body unit 1 is adjusted according to the surveying and setting out centerline. After the adjustment is completed, the second end of the telescopic support leg 5 is controlled to support the floor of the chamber. The length of the tunnel chamber lining trolley 100 can be adjusted according to the depth of the chamber.
[0070] Next, the position of the top mold unit 3 can be adjusted through the adjustment unit 6; then the second driving module 32 of the top mold unit 3 drives the top mold group 31 to move a certain height, so that the top mold group 31 pushes the first arch top mold 2112 of the side mold unit 2 to a certain height.
[0071] Next, the first driving module 22 of the side mold unit 2 drives the side mold group 21 to move to the designed position in the width direction of the vehicle body unit 1; then, the second driving module 32 of the top mold unit 3 drives the top mold group 31 to move to the designed position, so that the top mold group 31 and the side mold group 21 form an annular shaping surface of the chamber lining.
[0072] Next, the positions of the first arch top mold 2112 and the first bottom mold 2114 are adjusted, so that the first telescopic rod 2311 and the second telescopic rod 2312 of the first telescopic rod assembly 231 respectively support the first arch top mold 2112 and the first bottom mold 2114, and limit the position of the first arch top mold 2112 and the first side mold 2113. When the first bottom mold 2114 is installed, the fifth sealing strip 2118 at the bottom of the first bottom mold 2114 is tightly attached between the first bottom mold 2114 and the floor of the chamber, thereby sealing the gap between the first bottom mold 2114 and the floor of the chamber.
[0073] Next, the end wall module 41 is installed. During installation, the end wall top formwork assembly 411 is first positioned and fixed, then the end wall middle formwork assembly 412 is positioned and fixed, and finally the end wall bottom formwork is positioned and fixed; at the same time, when the installation of the end wall module 41 is completed, the tunnel chamber lining trolley 100 is in the expanded position. At this time, the third sealing strip 2117 is tightly attached between the side formwork assembly 21 and the end wall module 41, the fourth sealing strip is tightly attached between the top formwork assembly 31 and the end wall module 41, and the sixth sealing strip 414 is tightly attached between the end wall bottom formwork assembly 413 and the floor of the chamber.
[0074] Next, the position of the tunnel chamber lining trolley 100 is reviewed to ensure that the tunnel chamber lining trolley 100 is in the designed position; the main line lining trolley 101 is moved to the designed position, and the tunnel chamber lining trolley 100 and the main line lining trolley 101 are docked. During docking, the docking of the circumferential lap joint 2111 and the matching lap joint with the side form of the main line lining trolley 101 is observed through the casting window of the tunnel chamber lining trolley 100 and / or the main line lining trolley 101, and it is ensured that the first sealing strip 2116 and the second sealing strip are squeezed and deformed and tightly attached between the tunnel chamber lining trolley 100 and the main line lining trolley 101.
[0075] Next, the concrete pouring construction of the chamber lining and the tunnel mainline lining is carried out. The pouring process is from bottom to top, and the pouring of concrete is monitored through the pouring windows of the tunnel chamber lining trolley 100 and / or the mainline lining trolley 101 to ensure full pouring. At the same time, during the concrete pouring process, the first and second attached vibrating units are turned on to vibrate the concrete of the chamber lining to ensure the density and appearance quality of the concrete of the chamber lining.
[0076] When the concrete strength meets the demoulding conditions, the mainline lining trolley 101 is demoulded first, and then the mainline lining trolley 101 is moved; then, the tunnel chamber lining trolley 100 is demoulded. When the tunnel chamber lining trolley 100 is demoulded, the second driving module 32 of the top mold unit 3 is first driven to move the top mold downward; then the support of the first supporting module for the side mold group 21 is released, and then the first arch top mold 2112 of the side mold group 21 of the side mold unit 2 is separated from the chamber lining; then the first driving module 22 is used to control the first side mold 2113 and the first bottom mold 2114 to separate from the chamber lining, and then the first bottom mold 2114 is folded and contracted; then the support of the telescopic support leg 5 for the vehicle body unit 1 is released; then the support of the second supporting end wall mold group 41 is released, and then the end wall bottom mold assembly 413, the end wall middle mold assembly 412 and the end wall top mold assembly 411 are demoulded from the chamber lining in turn; finally, the tunnel chamber lining trolley 100 is moved out of the chamber.
[0077] In summary, it can be seen that through the structural design of the tunnel chamber lining trolley, the tunnel chamber lining trolley can form a shaping surface for auxiliary chamber lining through the side formwork unit, top formwork unit and end wall formwork unit thereon, so as to solve the problems of deformation, mold running and concrete leakage of the chamber formwork in the existing manual production of formwork, and can also ensure the molding quality of the chamber lining (including the flatness of the chamber lining surface, the molding quality of the chamber mouth lining curve, etc.) and the molding accuracy; in addition, the tunnel chamber lining trolley can also greatly improve the construction efficiency of the chamber lining and can be reused.

The top form unit 73 includes a set of top modules 731 and a set of second drive modules 732. The end wall form unit 74 is connected to the second ends of the second arch top form, the second side form, and the second bottom form.
[0080] Lining pouring trolley system embodiment
[0081] Reference Figure 15 The lining casting trolley system includes a tunnel chamber lining trolley 81 and a mainline lining trolley 82, wherein the tunnel chamber lining trolley 81 is the tunnel chamber lining trolley described in the first or second embodiment of the tunnel chamber lining trolley. When the lining casting trolley system is constructing the chamber lining and the tunnel mainline lining, the tunnel chamber lining trolley 81 is first moved into the chamber 801 and placed in the deployed position; then the mainline lining trolley 82 is moved into the tunnel mainline 802 and positioned at the chamber entrance, so that the circumferential lap joint surface and the mating lap joint surface of the tunnel chamber lining trolley 81 are adjacent to the side form of the mainline lining trolley 82.
[0082] In summary, it can be seen that through the design of the lining casting trolley system, the tunnel chamber lining trolley can cooperate with the mainline lining trolley to simultaneously form the chamber lining and the tunnel mainline lining, thereby better improving the chamber forming quality and safety of use.
