Stratum reinforcement method for water-rich sand layer under tramcar track
The invention relates to the technical field of pipe jacking construction, in particular to a method for reinforcing a water-rich sand layer under a tramcar track. A method for reinforcing a water-rich sand layer under a tramcar track comprises the steps that surveying and setting out are conducted, and a construction range is set out according to the jacking axis and the distance; geological supplementary survey: carrying out geological supplementary survey according to the construction range; ground grouting reinforcement is conducted, specifically, ground grouting reinforcement is conducted on the ground subjected to survey lofting and geological supplementary exploration; the periphery of the pipe jacking machine is grouted in the circumferential direction, pipe jacking construction is conducted on the water-rich sand stratum below the tramcar track through the pipe jacking machine, and the periphery of the pipe jacking machine is grouted and reinforced; and checking is conducted, specifically, the grouting effect is checked. When pipe jacking construction is carried out on the water-rich sand stratum under the tramcar track, the water-rich sand stratum under the tramcar track is reinforced by matching ground grouting reinforcement with peripheral grouting reinforcement of a pipe jacking machine, and collapse deformation of the tramcar track caused by the influence of construction of the pipe jacking machine on the water-rich sand stratum is prevented.
本发明涉及顶管施工技术领域，具体涉及一种有轨电车轨道下富水砂层地层加固方法。一种有轨电车轨道下富水砂层地层加固方法，包括：测量放样，按照顶进轴线和距离在地方放样出施工范围；地质补勘，根据施工范围进行地质补勘；地面注浆加固，对进行测量放样以及地质补勘后的地面进行地面注浆加固；顶管机外周向注浆，采用顶管机在有轨电车轨道下方的富水砂层地层进行顶管施工，在顶管机外周向注浆加固；检查，对注浆效果进行检查。在有轨电车轨道下富水砂层地层进行顶管施工时通过地面注浆加固配合顶管机外周向注浆加固对有轨电车轨道下的富水砂层地层进行加固，防止有轨电车轨道受顶管机在富水砂层地层进行施工的影响而导致塌陷变形。
