Abstract

The present invention provides a segment, segment assembly, and a grouting apparatus. The segment includes the grouting apparatus comprising: a segment body formed of a concrete material and having aninjection hole penetrated therethrough; an injection pipe member fitted into the injection hole and formed hollow; and a backflow prevention member provided on the injection pipe member to transfer afluid in one direction such that the injection pipe member is opened when an injection material is injected and the fluid is prevented from flowing backward in the direction opposite to the directionin which the injection material is injected.

Description

technical field [0001] The present invention relates to a segment, a segment assembly and a grouting device, and in more detail, relates to a segment, a segment assembly and a grouting device with the function of preventing backflow. Background technique [0002] Generally speaking, in order to excavate a tunnel or install an underground structure under a structure located on the upper part of the weak surface, the tunnel should be planned to be constructed on a rock formation or a solid ground, or when there is a weak surface, the grouting method must be carried out before excavating the tunnel. Excavate the supporting force of the surface, thereby blocking the groundwater contained in the surface, preventing the collapse and over-excavation of the excavation surface, and ensuring the stability of the excavation surface. [0003] When excavating a tunnel, the excavation area is larger than the outer diameter of the segments, so that the segments are easily connected, and th...
