Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of tunnel secondary lining construction, in particular to a synchronous secondary lining construction system and a construction method thereof. BACKGROUND

[0002] Pipeline extension is an important step in slurry balance shield machine construction. In the operation process of the slurry balance shield machine, the slurry pipe cannot be disconnected, and the slurry pipe needs to be continuously extended with the advancement of the main machine. However, the slurry pipeline in various forms of pipeline extension devices needs to be suspended on the tunnel segment wall through a tool, which will affect the subsequent secondary lining construction of the tunnel, such as the construction of the walkway on both sides of the railway tunnel, the construction of the side wall of the highway tunnel, and the secondary lining of the river-crossing tunnel. Therefore, before the tunnel secondary lining construction, the pipeline needs to be operated for secondary arrangement on the tunnel wall. This process needs to disconnect the pipeline, causing the slurry balance shield machine to stop, and affecting the overall construction efficiency of the tunnel.

[0003] In summary, how to realize synchronous secondary lining in tunnel excavation construction, especially how to perform synchronous secondary lining in the process of slurry balance shield machine excavation construction, is a technical problem to be solved.

[0006] The technical solution of the present application is:

[0007] The synchronous secondary lining construction system comprises a pipeline extension device connected to a trailer, a walking table pouring trolley and a secondary lining trolley arranged in sequence behind the trailer, the walking table pouring trolley comprises a walking table pouring trolley walking unit for walking on both sides of a box culvert and a walking table pouring unit for pouring a walking support structure of the secondary lining trolley on the outside of the box culvert, and a pipeline tool is arranged behind the pipeline extension device for positioning a slurry pipeline on the box culvert or cast-in-place ground. The synchronous secondary lining construction system can pour secondary structure lining while the slurry balance shield tunneling machine is excavating, specifically, the pipeline extension device can be synchronized with the slurry balance shield tunneling machine to add pipes and extend the slurry pipeline, the slurry pipeline behind the pipeline extension device can be directly fixed on the box culvert through the pipeline tool, avoiding the influence of the slurry pipeline suspended on the pipe segment on the secondary structure construction behind.

[0044] Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered part of the specification.

[0045] An object of the present application is to provide a synchronous secondary lining construction system that can meet the synchronous secondary lining construction during the construction of a slurry balance shield machine, avoid the secondary pipeline arrangement operation during the subsequent secondary lining construction, realize the synchronous assembly of the secondary lining under the non-stop state, improve the construction efficiency, and reduce the construction process.

[0046] To achieve the above object, the present application has a trailer, a pipeline extension device, a pipeline arrangement tool, a secondary lining trolley, etc. The trailer provides support for the pipeline extension device. The pipeline extension device is composed of a structure assembly, a pipeline assembly, and a slurry pipe crane. The structure assembly is the pipeline support of the entire pipe replacement device and the walking unit on the trailer. The pipeline assembly is the slurry pipeline that meets the slurry inlet and slurry outlet. The slurry pipe crane is used for hoisting and transporting the slurry pipe during pipeline extension. The pipeline arrangement tool is a device designed to support the pipeline to meet the pipeline extension and synchronous secondary lining. The secondary lining trolley is a walking frame unit that can perform synchronous secondary lining construction at the tail of the slurry balance shield machine while tunneling. It has the functions of walking, planting, pouring, and troweling, and can realize the tunnel shield construction segment assembly, secondary lining walking platform, and synchronous forming of the secondary lining segment.

[0047] In the present application, by changing the way of fixing the inlet and outlet slurry pipes in the inner wall of the segment in the past, a new pipeline extension device and tool are designed. The inlet and outlet slurry pipes are placed on the box culvert or cast-in-place ground, and the remaining pipelines (such as water pipes and high-voltage cables) that assist the slurry balance shield machine in tunneling are also placed on the box culvert or cast-in-place ground through the tool. At this time, there are no other pipelines on the inner wall of the segment. The trolley for secondary lining construction is carried at the tail of the shield machine, which is divided into a walking platform construction trolley and an arc segment construction trolley. Since there are no other obstacles on the inner wall of the segment, there is no need for secondary pipeline operation during the secondary lining construction. The secondary lining construction can be carried out simultaneously at the tail of the slurry balance shield machine while tunneling. The two can be carried out simultaneously. The secondary lining construction trolley has the functions of walking, planting, pouring, and troweling, and can realize integrated forming without the need for secondary construction. The pipeline extension device and the secondary lining trolley in the construction method simultaneously consider material transportation, ventilation pipe arrangement, pipeline arrangement, etc., and are a relatively comprehensive solution for slurry balance shield machine secondary lining construction.

[0048] According to the present application, the secondary lining construction of the shield machine can be more efficiently realized, the problem of secondary pipeline arrangement during subsequent tunnel construction is solved, the secondary lining construction while tunneling is met, repeated construction is avoided, the construction process is reduced, the construction efficiency is improved, the construction method is simple and feasible, the device is simple and easy to manufacture, and it can be widely applied to tunnel construction.

[0049] Specific embodiments are described below:

[0050] A synchronous secondary lining construction system, such as Figure 1 and Figure 5 As shown, the system includes a pipeline extension device 2 connected to a trailer 1. Behind the trailer 1, a traveling platform pouring trolley 3 and a secondary lining trolley 4 are arranged in sequence. The traveling platform pouring trolley 3 includes a traveling platform pouring trolley traveling unit 304 for traveling on both sides of the box culvert 6 and a traveling platform pouring unit 303 for traveling support structure 12 for pouring the secondary lining trolley 4 on the outside of the box culvert 6. Behind the pipeline extension device 2, a pipeline tooling 8 is arranged for positioning the mud pipeline 7 on the box culvert 6 or the cast-in-place ground.

[0051] The synchronous secondary lining construction system provided in this embodiment can perform secondary structure lining pouring while the slurry balance shield tunneling machine is tunneling. Specifically, during the tunneling process of the slurry balance shield tunneling machine, the pipeline extension device 2 can simultaneously add pipes, thereby extending the slurry pipe synchronously. The slurry pipe 7 behind the pipeline extension device 2 can be directly fixed to the box culvert 6 through the pipeline fixture 8, avoiding the slurry pipe 7 being suspended on the tunnel segment 5 and affecting the subsequent secondary structure construction. However, fixing the slurry pipe 7 to the box culvert 6 requires avoiding interference with the secondary lining trolley and material transfer equipment. Therefore, the secondary lining trolley's traveling support structure 12 is constructed through the traveling platform pouring trolley 3. This ensures that the secondary lining trolley will not interfere with the slurry pipe 7 and material transfer equipment while traveling and pouring the secondary lining structure 13 on the traveling support structure 12.

[0052] Furthermore, both the traveling platform pouring trolley 3 and the secondary lining trolley are equipped with independent traveling units, which can greatly improve the flexibility of construction, and they do not have to follow the trailer 1 in sync.

[0053] Based on the above embodiments, as a preferred embodiment of the synchronous secondary lining construction system, such as... Figure 2 As shown, a relay pump 9 is installed behind the pipeline extension device 2 for positioning on the box culvert 6. The relay pump 9 is used to pump mud from the mud pipeline 7. This embodiment provides a better layout scheme. As the tunnel excavation progresses, the mud pipeline 7 becomes longer and longer, requiring the relay pump 9 to relay the mud. Placing the relay pump 9 on the box culvert 6 can improve space utilization and avoid interference with the construction of the traveling platform pouring trolley 3 and the secondary lining pouring trolley 4.

[0054] Based on the above embodiments, as a preferred embodiment of the synchronous secondary lining construction system, such as... Figure 4As shown, the secondary lining trolley is a secondary lining pouring trolley or a secondary lining assembling trolley, when the secondary lining trolley is a secondary lining pouring trolley, a transport vehicle 10 for conveying pouring material to the walking pouring trolley 3 and the secondary lining pouring trolley 4 is further included. The embodiment provides two preferred structural modes of the secondary lining trolley, one of which is the secondary lining pouring trolley 4 for the cast-in-place secondary lining structure 13, and the other of which is the secondary lining assembling trolley for assembling the prefabricated secondary lining piece. Meanwhile, the embodiment provides the transport vehicle 10 and a more optimal arrangement scheme, preferably, the slurry pipeline 7 and the relay pump 9 are arranged on the same side of the box culvert 6, and the transport vehicle 10 passes on the other side of the box culvert 6.

The embodiment provides a more reliable positioning structure at the pipeline extension, specifically, the inlet pipe and the outlet pipe in the pipeline assembly 202 are reliably positioned, because the inlet pipe and the outlet pipe in the pipeline assembly 202 are used to connect the slurry pipeline in front of the trailer 1 with the slurry pipeline 7 behind the trailer 1, and the slurry pipeline in front of the trailer 1 is higher in horizontal height, while the slurry pipeline 7 behind the trailer 1 is lower in horizontal height, so the inlet pipe and the outlet pipe in the pipeline assembly 202 are both transition elbows, and the elastic supporting wheel 204 and the hoisting support 205 can more reliably position and support them.
