Embodiment

[0031] A shield machine grouting anti-blocking component, its structure is as follows Figure 1-3 As shown, it mainly includes a grouting head 1, a grouting piston 2, a liquid pipeline 4 and a liquid B pipeline 5. Wherein the grouting head guide rod 3 is affixed to the inner wall of the grouting head 1 through a cross brace, such as Figure 4 As shown, and matched with the axial hole 8 of the piston; the grouting piston 2 is installed inside the grouting head 1, and the rear end of the grouting piston 2 is connected with the piston rod of the oil cylinder, and the piston movement can be performed inside the grouting head 1, so that The volume of the mixing zone 7 changes; the inside of the grouting head 1 is close to the outlet end as the mixing zone 7, and the mixing zone 7 communicates with the A liquid pipeline 4 on one side, and communicates with the piston axial hole 8 of the grouting piston 2 at the rear end. During the two-liquid grouting, the A liquid injected into th...

Abstract

The invention relates to a shield machine grouting anti-blocking component. The shield machine grouting anti-blocking component comprises a grouting head and a grouting piston which moves in the grouting head in a reciprocating mode. Two liquid injection pipelines are connected onto the grouting head, a pore passage is formed in the grouting piston, and the front end of the grouting piston and theinner wall of the grouting head form a mixing cavity. The mixing cavity communicates with one liquid injection pipeline, and the other liquid injection pipeline communicates with the pore passage formed in the grouting piston. Compared with the prior art, according to the shield machine grouting anti-blocking component, the structure is simple, the occupied space is small, the high economical efficiency and reliability are achieved, the grouting anti-blocking component adapts to the characters of different grout and can adapt to grout proportion change, the grouting efficiency and effect areimproved, cleaning water is saved, grout waste is avoided, and the grouting blocking problem is basically solved.

Description

technical field [0001] The invention relates to the field of shield tunneling method grouting construction, in particular to a shield tunneling machine grouting anti-blocking component. Background technique [0002] During shield excavation, it is necessary to fill in an appropriate amount of grouting within a very short period of time when the shield tail gap (that is, the segmental lining protruding from the shield tail and the building gap in the soil) is formed through synchronous grouting that is carried out synchronously with the excavation. The slurry material will fill it densely, so that the surrounding rock and soil can be supported in time, effectively prevent the collapse of the soil, control the subsidence of the ground surface, fix the position of the segment, prevent the accumulation of water behind the segment, and ensure that the shield tunnel is not damaged after construction. Deformation and no water leakage. [0003] The stability and effectiveness of th...
