Reinforcing structure for soil body above shallow-buried tunnel and construction method of reinforcing structure
The invention discloses a reinforcing structure for a soil body above a shallow-buried tunnel and a construction method of the reinforcing structure, and relates to the field of tunnel engineering.The construction method comprises the steps that firstly, before tunnel construction, a reinforcing supporting device is arranged in a foundation on the lower side of a road; 2, a bearing platform is poured at the upper ends of the lime-soil compaction piles in the length direction of the tunnel, and a bottom cross beam is erected on the bearing platform; 3, main beams are erected on the bottom cross beams, and the main beams are connected with the lime-soil compaction piles; 4, static pressure compaction is conducted on the roadbed, then the road surface is poured, after the road surface is coagulated, beam plates are laid on the road surface, and the beam plates are connected with the main beams; 5, after tunnel construction is completed, the beam plates are dismantled, and the road surface is laid again through asphalt; by means of the method, the foundation on the lower side of the road is reinforced in the tunnel construction process, a reinforced structure is formed, the strength of the foundation on the lower side of the road can be effectively enhanced, tunnel construction safety is guaranteed, and the method has the advantages of being convenient to construct, reinforcing through lime soil, short in construction period, capable of saving cost and good in reinforcing effect.
本发明公开了一种浅埋隧道上方土体加固结构及其施工方法，涉及隧道工程领域，包括步骤1：在隧道施工前，在道路下侧地基中做加固支撑装置；步骤2：沿隧道长度方向在灰土挤密桩上端浇筑承台，并在承台上搭设底横梁；步骤3：在底横梁上搭设主梁，并将主梁与灰土挤密桩连接；步骤4：对路基进行静压夯实，然后浇筑路面，待路面凝结后，在路面上铺设梁板，并将梁板与主梁连接；步骤5：在隧道施工完成后，拆除梁板，用沥青重新进行路面铺设；通过本方法在隧道施工过程中对道路下侧地基进行加固，形成加固结构，可以有效增强道路下侧地基的强度，保证隧道施工安全，具有施工方便，利用灰土进行加固，施工周期短、节省费用和加固效果好的特点。
