Construction technology of adjacent mountain gravity type wharf embankment guiding foundation bed
The invention discloses a construction process of a guide embankment foundation bed of a gravity type wharf adjacent to a mountain, the construction is divided into three sections, and the elevation of the rock surface where the root section of the guide embankment is located is more than + 3.0 m; the elevation of the reef plate rock surface where the middle section of the guiding embankment is located is reduced from + 3 m to-6 m along the bank; the elevation of the reef plate rock surface where the initial section of the guiding embankment is located is reduced from-6.0 m to-12 m along the bank; when the foundation bed construction process of the initial section of the guiding embankment is carried out, underwater reef explosion construction is adopted; when the foundation bed construction process of the root section of the guiding embankment is carried out, the land shallow hole and deep hole blasting combined technology is adopted; when the foundation bed construction process of the middle section of the guiding embankment is carried out, an area with the rock surface elevation below + 0 m is pushed, filled and leveled through block stones to form a construction platform with the elevation of + 3.0 m, and then block stone covering layer guiding hole drilling, bed rock solid hole drilling and blasting operation are sequentially carried out on the construction platform through a hydraulic down-the-hole drill. The problem that the conventional onshore and underwater reef explosion process cannot be realized on the middle section of the guiding embankment is solved.
本发明公开了一种邻近山体重力式码头引堤基床的施工工艺，分三段施工，引堤根部段所处的岩面标高均在+3.0m以上；引堤中部段所处的礁盘岩面标高从+3m顺岸降至‑6m；引堤起始段所处的礁盘岩面标高为从‑6.0m顺岸降至‑12m；进行引堤起始段的基床施工流程时，采用水下炸礁施工；进行引堤根部段的基床施工流程时，采用陆上浅孔和深孔爆破相结合的工艺；进行引堤中部段的基床施工流程时，先将岩面标高在+0m以下的区域采用块石推填、平整形成标高为+3.0m的施工平台，接着在施工平台上采用液压潜孔钻机依次进行块石覆盖层引孔钻设、基岩实孔的钻进和爆破作业。本发明解决了引堤中部段无法实现常规的陆上和水下炸礁工艺的难题。
