The use of lining trolleys to complete the concrete pouring can not only ensure the construction quality and aesthetics of the concrete structure, but also reduce labor costs and save construction time.

For underground projects with many caverns and distributed in a planar shape, if conventional trolleys are used to construct the lining structure, it will bring about two negative effects: one is the sharp increase in the number of trolleys required. The construction cost is bound to double; the second is the increase in the number of trolleys, which increases the difficulty of the trolley’s turnover in the cave, increases the assembly and disassembly time of the trolley, and undoubtedly also affects the transportation of materials and muck, which greatly increases The risk of construction delays. The use of traditional formwork and scaffolding methods to complete the construction of the lining structure of this type of project requires repeated disassembly and assembly of scaffolding and formwork.

The following is the assembly principle of a prefabricated lining trolley that can realize rapid turnover:

The trolley of the invention can quickly complete assembly and disassembly between adjacent sections. The assembly principle is divided into two stages: the first stage is the assembly installation of the heightened mast. The heightening mast is assembled on the ground and superimposed on the base mast by hoisting to complete the assembly of the mast assembly. The second stage is the prefabricated installation of the top template assembly. The top template assembly is assembled on the ground synchronously, and then superimposed on the mast assembly by hoisting to complete the second assembly. Use an excavator or set a pre-embedded lifting point on the roof of the cave to carry out the lifting operation. According to the lifting capacity, the top formwork assembly is split into several top formwork assembly units, and the parts are lifted to the door frame assembly before completion A simple assembly is enough.

The trolley of the present invention can complete rapid transfer between non-adjacent sections, which greatly saves the time that the trolley needs to be disassembled and then transferred to the next section for reassembly. The disassembly process of the trolley of the present invention is opposite to the assembling process. First, the top formwork assembly is hoisted and unloaded to the ground, and the whole is transferred to the next section to wait for hoisting again. Use the same operation to unload the heightening mast assembly to the ground, and transfer it to the next section as a whole to wait for it to be hoisted again. It is necessary to judge whether the top template assembly needs to be widened according to the size of the next section, the side template assembly should be heightened, partial parts replacement or reinforcement of the heightened mast assembly, and the mechanical screw rod Make adjustments, etc.

The following is the turnover principle of a prefabricated lining trolley that can realize rapid turnover:

If cavern A and cavern C are non-adjacent caverns of a certain underground project, they have similar or identical cross-sectional dimensions, which conform to the scope of application of the trolley of the present invention. The two caverns are connected by the main channel B, and the spatial relationship is shown in Figure 4. After using the trolley of the present invention to finish the lining of the cavern A, the trolley needs to be quickly transferred to the cavern C for lining construction.

a. If the cross-sectional dimensions of cavern A and cavern C are the same, and the space of cavern B is enough for the trolley to be transported without disassembly and assembly, then only need to follow 3 steps to complete the transport:

Step 1: Evacuate the trolley in cavern A along the track to cavern B.

Step 2: Put temporary support structures such as piers on the bottom surfaces of the lower longitudinal beams of each trolley, start the hydraulic system of the trolley, and allow the hydraulic cylinder to contract to drive the traverse mechanism and the traveling system to separate from the track. The weight of the trolley is borne by the temporary support structure. Remove the matching bolts in the traverse mechanism, and with the assistance of the bearings in the traverse mechanism, rotate the lower turntable and its connected walking system by 90 degrees, and then use the matching bolts to fix the traverse mechanism. Pull out the track and move it to cave B to reposition it to welcome the lowering of the walking wheels again. Start the hydraulic system of the trolley again to allow the hydraulic cylinder to expand and contract to drive the traverse mechanism and the traveling system out of contact with the steel rail again, and remove the temporary support mechanism. At this time, the weight of the trolley is again applied to the track through the hydraulic system and the traveling system. Start the trolley traveling system and let the trolley travel to the exit of cave C. The purpose of this step is to keep the upper structure of the trolley in the same position, let its traveling wheels rotate 90 degrees in cave B, and then continue to walk to the intersection with cave C.

Step 3: The operation of moving the trolley to cavern C only needs to repeat the operation of step 2, rotate the walking wheel 90 degrees again to restore it to its original position, and advance cavern C to start the lining construction.

b. If the cross-sectional dimensions of cavern A and cavern C are similar, or the space of cavern B is not enough for the trolley to be transported without disassembly and assembly, then only the top template assembly and side of the trolley The template assembly or heightening mast assembly is unloaded and transferred to the vicinity of the hanging point of cave C to complete the necessary heightening mast adjustment or adding top and side templates and other preparations. Then, use the operations in steps 1-3 above to move the basic door frame assembly to the vicinity of the hanging point of the cavern C, and complete the assembly-type assembly of the trolley in the cavern C.

The above are only the preferred embodiments of the present utility model. It should be pointed out that for those skilled in the art, without departing from the structure of the present utility model, several modifications and improvements can be made, and these will not affect the present utility model. The effect of implementation and the practicability of the patent.
