[0041] Please refer to the attached document. Figures 1-5 This application illustrates a detachable and adjustable trackless stepping lining trolley provided in an embodiment of the present application, used for concrete pouring during tunnel construction. Specifically, it includes: a portal-shaped passage component, template assemblies installed above and on both sides of the portal-shaped passage component, vertical hydraulic cylinders 11 fixedly installed at both ends of the portal-shaped passage component, and a first heightening seat assembly 4 and a second heightening seat assembly 5 slidably installed at the bottom of the portal-shaped passage component, with a stepping hydraulic component 18 installed between the second heightening seat assembly 5 and the bottom of the portal-shaped passage component.

[0042] like Figure 1 , Figure 2As shown, during the step-by-step movement, the first lifting seat assembly 4 and the second lifting seat assembly 5 need to be reset first, and then the vertical hydraulic cylinder 11 is retracted. The first lifting seat assembly 4 and the second lifting seat assembly 5 support the portal passage component and the template assembly above. The stepping hydraulic component 18 extends, driving the portal passage component and the template assembly above to slide relative to the first lifting seat assembly 4 and the second lifting seat assembly 5, thus realizing the movement of the portal passage component and the template assembly above. Then, the vertical hydraulic cylinder 11 extends and supports the ground, lifting the portal passage component and the template assembly above upwards. The first lifting seat assembly 4 and the second lifting seat assembly 5 are in a suspended state. The first lifting seat assembly 4 and the second lifting seat assembly 5 are manually or with the help of auxiliary tools to be reset, and then the above-mentioned step-by-step movement is repeated. Generally, each stroke is about 0.6m (corresponding to the designed stroke of the stepping hydraulic component 18).

[0043] The second heightening seat assembly 5 includes an upper block 501 and a lower block 502 distributed vertically. The upper block 501 and the lower block 502 are detachably fixed and installed, and the mating surface of the upper block 501 and the lower block 502 is an 8°-30° inclined surface. The first heightening seat assembly 4 and the second heightening seat assembly 5 have the same structure.

[0044] like Figure 3 As shown, when walking on a steep slope that transitions to a flat slope, the corresponding lower block of the first heightening seat assembly 4 or the second heightening seat assembly 5 located on the steep slope is removed. This ensures that the first heightening seat assembly 4 and the second heightening seat assembly 5 are stably supported on the ground, and that the gate-shaped passage component and the template assembly above are basically in a horizontal state. Through the above structural design, it can be adapted to use on slopes and keep the gate-shaped passage component and the template assembly above horizontal, making it safer to use.

[0045] In one embodiment, the portal tunnel component includes: a plurality of portal structures 1 spaced apart along the tunnel length direction and a top crossbeam 2 and a bottom crossbeam 3 fixedly connected to the sides of the plurality of portal structures 1, wherein the top crossbeam 2 is close to the top and the bottom crossbeam 3 is close to the bottom.

[0046] The top beam 2 and the bottom beam 3 connect several separate gantry structures 1 into a whole structure to form a passage. The gantry structure 1 is formed by welding and fixing trusses made of I-beams and channel steel. A clearance passage for vehicles is reserved inside the gantry structure 1.

[0047] The length of the top crossbeam 2 is determined by the theoretical lining length and the formwork overlap length. Generally, the theoretical lining length can be 9m or 12m, or it can be divided into two 4.5m or two 6m sections. The formwork overlap length is 0.1m. The bottom crossbeam 3 is welded and fixed to the bottom of the portal frame structure 1. The length of the bottom crossbeam 3 is determined by the theoretical lining length and the formwork overlap length. Generally, the theoretical lining length can be 9m or 12m, or it can be divided into two 4.5m or two 6m sections. The formwork overlap length is 0.1m.

[0048] In one embodiment, the template assembly includes: a top template 7 and side templates 10 disposed on both sides of the top template 7. The top of the side templates 10 is hinged to the top template 7. A plurality of side template supports 9 and side hydraulic cylinders 8 are installed between the side templates 10 and the gantry structure 1. A top template support 6 is installed between the side templates 10 and the gantry structure 1 and near the junction of the side templates 10 and the top template 7.

[0049] Both the lateral formwork support 9 and the top formwork support 6 are extendable and adjustable threaded rod structures. The lateral hydraulic cylinder 8 is used to increase the stability of the lateral formwork 10 and the inner side of the tunnel, and to prevent the lateral formwork 10 from being displaced by force during the grouting process.

[0050] In one embodiment, both the top template 7 and the side template 10 are provided with reserved working windows 12 and reserved grouting holes 13. The reserved working window 12 is generally 500*500mm in size, and the inner diameter of the reserved grouting hole 13 is controlled at about 125mm, all in order to facilitate grouting operations.

[0051] In one embodiment, the bottom of the top template 7 and the top of the gantry structure 1 form a reserved ventilation duct area 14, which is an elliptical structure and serves as a ventilation function.

[0052] In one embodiment, an internal support 15 is fixedly installed on the inner side of the gantry structure 1. The internal support 15 can increase the structural strength of the gantry structure 1. The internal support 15 adopts a detachable structure, and whether to install it is considered comprehensively based on the actual needs of the site, the size of the opening, and the load conditions.

[0053] In one embodiment, at least one end of the portal access member is equipped with an operating ladder 16 for construction workers to climb.

[0054] In one embodiment, the portal-shaped passage component is provided with several sections, and adjacent portal-shaped passage components are fixedly installed by connecting bolts 17. The bolt installation points are detachable, that is, a single section can be used according to actual needs.

[0055] Other embodiments of the present invention will readily occur to those skilled in the art upon consideration of the specification and practice of the disclosure herein. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of the present invention and include common knowledge or customary techniques in the art not disclosed herein.
