Tunnel entering section slope reinforcing excavation-free construction method
The invention discloses an excavation-free construction method for reinforcing a slope body of a tunnel entering section, which is characterized in that excavation-free reinforcement of the slope body of the tunnel entering section is reinforcement from the earth surface to the periphery of a tunnel hole, and a soft and loose covering layer and a full and strong weathering layer of the tunnel entering section are improved and reinforced on the spot by utilizing an original earth surface topography; the method comprises the following steps that (1) the range of a plane, needing to be reinforced, of the tunnel entering section is determined; (2) the depth, needing to be reinforced, of the tunnel entering section and the length of each grouting pipe are determined; (3) determining the arrangement distance of each grouting pipe, and marking each geological drilling point position on the surface of the slope body; (4) geologically drilling a slope body, and arranging a grouting pipe; (5) grouting to reinforce the stratum; and (6) after reinforcement, the tunnel is excavated according to general procedures. The method is convenient in process, economical, green and low-carbon, can flexibly and effectively determine the range of the slope reinforcing area of the tunnel-entering section, and can safely and efficiently implement tunnel-entering excavation.
本发明公开了一种隧道进洞段坡体加固免挖施工方法，所述的进洞段坡体免挖加固是从地表向隧道洞周加固，利用原生地表地形，对隧道进洞段较软、较松散的覆盖层和全、强风化层就地改良加固，并通过注浆形成与拟筑隧道洞周轮廓相适应的拱形加固体，包括以下步骤：(1)确定隧道进洞段需加固的平面范围；(2)确定隧道进洞段需加固的深度和各注浆管长度；(3)确定各注浆管的布置间距，坡体地表标示各地质钻孔点位；(4)坡体地质钻孔、安置注浆管；(5)注浆加固地层；(6)加固后按一般工序进洞开挖隧道。本发明工艺便捷、经济节约、绿色低碳，即可灵活有效地确定进洞段坡体加固区域范围，又能安全高效地实施隧道进洞开挖。
