DETAILED DESCRIPTION OF THE INVENTION

[0035] This embodiment will be described in detail with reference to the accompanying drawings.

[0036] When this embodiment is in use, it includes a support ring 1 located at the upper end. The function of the support ring 1 is to connect to the ground. The upper end of the support ring 1 is fixedly connected to the ground, and the lower end of the support ring 1 extends downward into the shaft as the top lining structure. In order to ensure the thickness of the support ring 1 to ensure connection stability while maintaining a lightweight design, the support ring 1 needs to adopt a hollow structure. The diameter of the lower end of the support ring 1 extending downward into the shaft determines the diameter of the lining structure. At the same time, the diameter of the lower end of the support ring 1 corresponds to the diameter of the shaft. A plurality of buckles 4 for connecting the lower structure are circumferentially distributed on the lower end surface of the part of the support ring 1 extending downward into the shaft. The lining formwork is connected through the buckles 4 at the lower end of the support ring 1.

[0037] There are multiple lining formworks, which line the side wall of the shaft downward in sequence. A single lining formwork is composed of a ring formed by a plurality of arc-shaped plates 2 with the same height and a connecting plate. Since the lining method is carried out step by step from top to bottom, it is impossible to first assemble it into a complete ring and then transport it downward. It needs to be disassembled first and then assembled. The diameters of the inner and outer sides of each arc-shaped plate 2 correspond respectively, and the contact parts at both ends are matched, so that the gap is reduced after the arc-shaped plates 2 are assembled, thus avoiding the decrease in supporting force. Since each arc-shaped plate 2 is arranged downward, the lining formworks are assembled downward step by step. Vertically penetrating slots 5 are respectively opened at the upper ends of each arc-shaped plate 2, and a plurality of buckles 4 are respectively fixedly connected at the positions corresponding to the slots 5 at the lower ends of the arc-shaped plates 2. The buckles 4 are used to connect the lower arc-shaped plates 2. By passing the buckle 4 upward through one end of the slot 5 and then rotating it by a certain angle to complete the clamping, the buckle 4 and the slot 5 after clamping cannot be separated in the vertical direction. The buckle 4 includes an arc-shaped structure and an arc-shaped middle piece extending downward. The lower end of the arc-shaped middle piece is arrow-shaped. The axis of the arc-shaped middle piece corresponds to the axis of the arc-shaped plate 2. The arrow-shaped structures at the lower ends of each buckle 4 have the same orientation. The shape of each slot 5 is arc-shaped and the radian corresponds to the radian of the arc-shaped middle piece. One end of the slot 5 is the same as the arrow shape of the buckle 4 and allows the buckle 4 to pass through. The other end of the slot 5 corresponds to the width of the arc-shaped middle piece. During assembly, the arc-shaped plate 2 is moved to the position where the buckle 4 and the slot 5 correspond, and then the arrow part of the buckle 4 is passed through the arrow-shaped notch part at one end of the slot 5, and then the arc-shaped plate 2 is rotated along the axis until the arc-shaped middle piece in the buckle 4 rotates to the other end of the slot 5. In this way, the buckle 4 cannot move downward. The slot 5 is located above the positioning slot 13, and the cavity formed by the positioning slot 13 is used to accommodate the buckle 4.

[0038] There are multiple arc-shaped plates 2 which together form a ring. During the installation process of each arc-shaped plate 2, since it is necessary to rotate a certain angle to complete the clamping connection, it is impossible to use all the arc-shaped plates 2 to form a complete ring, thus leaving a gap. At this time, the connecting piece 3 is clamped at the gap position to complete the complete ring. The connecting piece 3 is also an arc-shaped structure, and its radian corresponds to that of the arc-shaped plate 2, and the height of the connecting piece 3 corresponds to the height of the arc-shaped piece. The width of the connecting piece 3 corresponds to the width of the gap reserved by the arc-shaped piece. Multiple longitudinally arranged clamping pieces 18 are respectively fixedly connected to both ends of the connecting piece 3. The installation of the connecting piece 3 is a longitudinal movement, so that both ends of the connecting piece 3 are respectively clamped on the arc-shaped plate 2, thus forming a complete ring. In this way, the assembly action of the lining formwork for one layer is completed.

[0039] A conveying pipeline 6 is arranged inside the connecting piece 3. The upper and lower ends of the conveying pipeline 6 respectively cooperate with the upper and lower ends of the connecting piece 3. Through holes are respectively arranged at the corresponding positions of the upper and lower ends of the connecting piece 3 and the ends of the conveying pipeline 6. The upper end of the conveying pipeline 6 is the first connection port 14, and the first connection port 14 is fixedly connected to the upper end of the connecting piece 3. The lower end of the conveying pipeline 6 is the second connection port 15, and the second connection port 15 is connected to the lifting member 10. The lifting member 10 is vertically slidably connected to the lower end of the connecting piece 3. The diameter of the first connection port 14 is larger than that of the second connection port 15, and at the same time, the first connection port 14 and the second connection port 15 cooperate with each other. When the second connection port 15 moves downward along with the lifting member 10, it will be inserted into the first connection port 14 on the connecting piece 3 located below. In this way, the conveying pipelines 6 in multiple vertically arranged connecting pieces 3 can be respectively connected. Connecting heads 16 are respectively arranged in each of the conveying pipelines 6, and control valves 17 are respectively rotatably connected in each of the connecting heads 16. The communication of the conveying channels is controlled by the control valves 17, and the connecting heads 16 are used to connect the filling rings 7.

[0040] A filling ring 7 is arranged outside the lining formwork. The filling ring 7 includes an arc-shaped ring body, and the range of the ring body corresponds to the range of the arc-shaped plate 2 in the lining formwork. The filling ring 7 is a hollow structure, and the hollow part is used to fill fillers. According to the use scenarios, different materials are used for the fillers. When stable connection and long-term support are required, concrete is filled in the hollow part. After the concrete sets, it adheres to the side wall of the shaft, and at the same time, it avoids forming an uneven cavity between the side wall of the shaft and the lining formwork. When temporary support is required, air or water can be filled into the filling ring 7 and pumped out after the support is completed. If heat preservation treatment is required, heat preservation materials can be filled. Different materials are filled according to different requirements.

[0041] A plurality of positioning holes 19 are formed in the outer side of the arc-shaped plate 2. The support of the arc-shaped plate 2 is a temporary support. Through the connection between the buckle 4 and the clamping groove 5, the connection force is relatively small. After the arc-shaped plate 2 is installed, additional support is required for the arc-shaped plate 2 to make the lining formwork fit tightly with the side wall of the shaft. A plurality of positioning holes 19 for positioning are formed in the outer side surface of the arc-shaped plate 2. A mating hole 20 is formed at a position corresponding to the positioning hole 19 on the filling ring 7. The condensation rod 21 passes through the positioning hole 19 and the mating hole 20 from the inner side of the lining formwork and is inserted outward into the side wall of the shaft. When the condensation effect is not required, the condensation rod 21 can be replaced with a solid rod. In the formation where condensation is required, a condensation rod 21 with a hollow pipe is used. A circulating cooling medium is introduced into the hollow condensation rod 21, and the formation is frozen through the cooling medium. During the freezing of the formation, the geological structure with relatively rich underground water content is frozen, thereby completing the construction of the condensation method. Through holes are respectively formed at the extending ends of the condensation rod 21, and a check buckle 23 is rotatably connected in the through hole. An elastic member is provided between the extending end of the check buckle 23 and the condensation rod 21. The ground is connected through the check buckle 23 to prevent the condensation rod 21 from being pulled out outward, thereby improving the connection stability.

[0042] The arc-shaped plate 2 is a hollow structure. Arc-shaped tracks 24 are symmetrically arranged at the upper and lower ends of the arc-shaped plate 2 respectively. By filling the arc-shaped plate 2 with an arc-shaped structure in the arc-shaped track 24, the lining thickness is increased, thereby improving the support strength of the lining. In order to convey the arc-shaped plate 2 into the arc-shaped track 24, the support rod 25 on one of the arc-shaped plates 2 is set to be detachably connected, while the remaining support rods 25 are set to be fixedly connected. In this way, after the detachable support rod 25 is disassembled, the arc-shaped plate 2 can be moved into the arc-shaped track 24 from the disassembled part, and then the arc-shaped plate 2 is moved to the remaining part of the arc-shaped track 24. The arc-shaped plate 2 is continuously filled in the arc-shaped track 24 until the arc-shaped track 24 is filled with the arc-shaped plate 2, and then the detachable support rod 25 is fixedly connected.

[0043] Arc-shaped protection plates 26 are respectively fixedly connected to the outer sides of the lower end surfaces of each arc-shaped plate 2 and the outer sides of the lower end surfaces of the connecting members 3. The protection plate 26 is used to form a protection structure for the protection gap after the connection of each arc-shaped plate 2. Similarly, an arc-shaped protection plate 26 for connecting the mating lining formwork is provided on the outer side of the lower end surface of the support ring 1. The connection gap between each layer of lining formwork is shielded by the protection plate 26, and at the same time, the stability after the connection of adjacent lining formworks can be improved.

[0044] Obviously, the above embodiments are merely examples given for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the claims of this patent application.
