Problems solved by technology

However, due to the small diameter of the joints of the pipe jacking, it is difficult to accommodate multiple slag trucks working in parallel in the pipeline. Therefore, each time the slag trucks are filled with muck and transported to the exit of the tunnel, they return to reload the slag
As the excavation proceeds, this method will cause the slag truck to fail to return in time, resulting in slag accumulation in the tunnel or the inability of the screw machine to continuously discharge the slag.

Embodiment Construction

[0021] The present invention will be further described below in conjunction with accompanying drawing.

[0022] figure 1 Schematically shows a muck conveying device 100 for a pipe jacking construction method according to the present invention, which is integrally arranged in a tunnel pipe 101 . Such as figure 1 As shown, the muck conveying device 100 includes a conveyor belt 1 , which extends axially in the tunnel pipe 101 and moves in a circular motion to continuously transport the muck to the exit of the tunnel pipe 101 . The muck conveying device 100 also includes a support assembly supporting the conveyor belt 1 and a driving machine 41 (such as Figure 4 shown).

[0023] The conveyor belt 1 includes a muck receiving section 11 in the front area, a coil running section 12 in the middle area, and a muck releasing section 13 in the tail end area. These sections of conveyor belt 1 are supported and held by support assemblies, which will be described in detail below. The ...

Abstract

The invention discloses a muck transporter used for a pipe-jacking construction method. The muck transporter comprises a conveyor belt arranged in a tunnel pipeline, and the conveyor belt is tensioned and moves circularly. The conveyor belt extends in the axial direction of the pipeline, and comprises a muck receiving section located in a front area, a winding operation section located in a middle area, and a muck releasing section located in a tail area. Along with advancement of tunnel construction, the muck receiving section also advances forward, and meanwhile, the portion, located in the winding operation section, of the conveyor belt is gradually unfolded. According to the muck transporter, the conveyor belt is used for continuously transporting muck, and the conveyor belt adapts to advancement of tunnel construction. Muck is continuously discharged, and muck accumulation within a tunnel is avoided.

Description

technical field [0001] The invention relates to the field of tunnel excavation, in particular to a muck conveying device used in a pipe jacking construction method. Background technique [0002] In the process of tunnel construction, in order to avoid damage to roads and ground structures and affect people's life and work, it is more and more inclined to use trenchless technology to construct tunnels. Currently, the most commonly used trenchless technology is pipe jacking. [0003] The pipe jacking construction method is generally: use the jacking force generated by the jacking equipment to overcome the friction between the pipeline and the surrounding soil, so as to push the pipeline into the soil according to the designed slope, and transport away the muck generated by the excavation of the tunnel. After one section of pipeline has been jacked into the soil layer, the second section of pipeline is lowered to continue jacking until the construction is completed. [0004] ...
