More specifically, the present invention has a relatively low specific gravity, a long gel time, and a high compressive strength of the cured product, which is suitable for use as a light source in cavities such as the back of tunnel lining concrete in tunnel repair work.

空洞を充てんする方法がとられてきた。Conventional technology Conventionally, as a method for placing tunnel lining concrete, the method of pulling out concrete pipes using the reverse winding method has generally been adopted. No matter how much construction is done, cavities inevitably occur between the upper part of the arch and the ground, and especially when sewn fabric or hanging sheets are installed on the shoring, a considerable amount of cavities occur. When such cavities occur, the active specific pressure applied to the lining concrete becomes uneven, and the passive earth pressure of the ground cannot be used effectively, so the occurrence of cavities is preferable for the lining concrete. This is a phenomenon that does not exist. Therefore, a method of filling the cavity using mortar or the like has been used so far.

クリート巻厚が数口も不足して覆工コンクリートの背面

変圧を受け、覆工コンクリートのはく離やはく落が生じ
ているものもあることが分かった。By the way, a recent survey of tunnels that had deteriorated over time revealed that in such tunnels, the thickness of the concrete lining was several inches short, and the back surface of the concrete lining became quite hollow. It was found that the concrete was subjected to deformation, causing the concrete lining to peel or fall off in some cases.

それもある。When repairing a tunnel that has deteriorated over time by filling the cavity with mortar, etc., the mortar has a high specific gravity, so it is necessary to cover the cavity with only the weight of the injection material.
This is extremely dangerous from a security standpoint, as there is a risk that the concrete may fall, and even if it is filled with mortar, it will not be able to ensure the strength of the concrete against the insufficient thickness of the concrete lining.
There are other problems. Furthermore, when conventional railway tunnels in electric operation sections are repaired with mortar, turbid water from the mortar leaks from cracks in the concrete lining and drips onto the overhead wires, causing a short circuit and potentially causing train operation problems.

いう利点も有している。Since the specific gravity is considerably lower than that of cement-based injection materials, there is no risk of the degraded lining concrete falling or being destroyed by the weight of the injection material, making it an excellent injection material in terms of safety measures. Furthermore, unlike conventional mortar-based injection materials, it does not use water, so it has the advantage that it does not leak water and cause short-circuits in overhead wires, causing train operation problems.
