Tunnel reinforcing construction method for reinforcing by using preformed holes in inner wall of tunnel
The invention discloses a tunnel reinforcing construction method for reinforcing by using preformed holes in the inner wall of a tunnel, and aims to provide the tunnel reinforcing construction method for reinforcing by using the preformed holes in the inner wall of the tunnel, which can simplify the tunnel reinforcing construction steps, improve the tunnel reinforcing construction efficiency and achieve a good tunnel reinforcing effect. The method comprises the following steps: A, disassembling a plug on an inner wall preformed hole at a specified position on the inner wall of a tunnel, and forming a duct piece reinforcing hole in a shield duct piece; the walking vehicle runs to a designated position of the tunnel; b, a high-pressure jet grouting pile is constructed, a jet grouting drill rod of a high-pressure jet grouting pile machine passes through the pipe piece reinforcing hole, the high-pressure jet grouting pile is constructed in a soil layer on the outer side of the shield pipe piece of the tunnel, and one end of the high-pressure jet grouting pile is tightly attached to the outer wall of the shield pipe piece; then, a jet grouting drill rod of the high-pressure jet grouting pile machine is reset; and C, returning to the step A, and circulating in this way.
本发明公开了一种利用隧道内壁预留孔进行加固的隧道加固施工方法，旨在提供一种能够简化隧道加固施工步骤，提高隧道加固施工效率，且隧道加固效果好的利用隧道内壁预留孔进行加固的隧道加固施工方法。它包括以下步骤：A，将隧道内壁上指定位置的内壁预留孔上的堵头拆卸，在盾构管片上形成管片加固孔；行走车行驶至隧道的指定位置；B，施工高压旋喷桩，高压旋喷桩机的旋喷钻杆通过管片加固孔，在隧道的盾构管片外侧的土层内施工高压旋喷桩，且高压旋喷桩一端与盾构管片外壁紧密贴合；然后高压旋喷桩机的旋喷钻杆复位；C，返回A步骤，如此循环。
