Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] refer to figure 1 , the present invention provides a mortar tank conveying pipe of shield tunneling mixing station and its construction method, which has the characteristics of simple structure, convenient construction, good reliability, etc. It takes too long to unblock the pipe when it is blocked.
[0032] The mortar tank conveying pipe of the shield tunneling mixing station of the present invention will be described below in conjunction with the accompanying drawings.
[0033] Such as figure 1 and figure 2 As shown, the conveying pipe of the mortar tank of the shield mixing station of the present invention includes a protective pipe 10 ; a slurry conveying pipe 20 ; pads 30 ; and bolts 40 .
[0034] Wherein, the protection pipe 10 is pre-buried in the ground, the slurry delivery pipe 20 is penetrated in the protection pipe 10, an...

The invention relates to a shield mixing station mortar tank conveying pipe. The shield mixing station mortar tank conveying pipe comprises a protective pipe which is pre-embedded underground, a mortar conveying pipe body arranged in the protective pipe in a penetrating mode, and cushion blocks arranged between the protective pipe and the mortar conveying pipe body. The shield mixing station mortar tank conveying pipe has the beneficial effects that the shield mixing station mortar tank conveying pipe is formed by adopting the structure including an inner sleeve pipe and an outer sleeve pipe,accordingly, when being blocked, the conveying pipe can be unchoked only by pulling out the inner sleeve pipe for mortar conveying from the pre-embedded protective pipe without breaking the ground totake out the pre-embedded pipe, construction is easy, the consumed time is short, continuous operation of shield mortar filling can be recovered in time, and the influence on the construction period is small.
Description
technical field [0001] The invention relates to the technical field of shield tunneling construction, in particular to a mortar tank conveying pipe of a shield tunneling mixing station and a construction method thereof. Background technique [0002] The pipeline for conveying mortar in the mortar tank of the shield mixing plant is generally located in the temporary hardened ground on the ground. In order not to affect road traffic, the pipeline is usually buried under the ground aisle. Due to the characteristics of mortar, once the mortar in the delivery pipe is not transported for a long time and stays in the pipeline, the mortar will harden in the pipeline and block the pipe. However, shield grouting is a continuous operation, and it must be restored in time after the pipeline is blocked. However, since the mortar tank conveying pipeline of the shield mixing station is pre-buried underground, when a pipe blockage occurs, the road surface has to be broken, the excavated an...
