Construction method for sheet-pile wall of island building platform
The invention discloses a construction method for a sheet-pile wall of an island building platform. The construction method comprises the following construction steps: step 1, leveling and compacting to form a hole digging operation platform; secondly, anti-slide pile construction is conducted, an artificial groove-jumping excavation construction method is adopted for anti-slide piles, adjacent piles cannot be excavated at the same time, and when adjacent pile foundations are constructed, construction can be conducted after the strength of pile bodies of the adjacent pile foundations reaches 100%; rock breaking machines such as an air pick are directly adopted for excavation when the strongly weathered layer is excavated, if hard soil or large stones and the like are encountered, the hard soil or large stones and the like need to be crushed through the air pick and then cleaned one by one, the excavation depth of each section does not exceed 1 m, and when the geological condition in the hole is poor, the excavation depth of each section does not exceed 0.5 m, and a first-stage support is excavated; and after excavation of the underground slide-resistant pile is completed, a reinforcement cage is hoisted and placed, and concrete is poured. According to the method, the cost is low, the rock-soil body is stable in the excavation process of the slope, the pile top elevation of the anti-slide pile and a construction platform have no relevance, and potential quality and safety hazards caused by stress concentration in the steel bar planting process are avoided.
本发明公开了一种用于筑岛平台桩板墙的施工方法，施工步骤如下：步骤一、整平压实形成挖孔作业平台；步骤二、进行抗滑桩施工，抗滑桩采用人工跳槽开挖的施工方法，相邻桩不得同时开挖，若施工相邻桩基时，需待临近桩基桩身强度达到100％后才能进行施工；强风化层开挖时直接采用风镐等破岩机械进行开挖，若遇到硬土或大块石等还需先用风镐破碎后逐个清理，每节开挖深度不超过1m，当孔内地质条件差时，每节开挖深度不超过0.5m，开挖一级支护一级；地面以下抗滑桩开挖完成后，吊放钢筋笼并灌注混凝土。本发明成本较低、边坡在开挖过程中岩土体稳定、抗滑桩桩顶标高与施工平台没有关联性等条件，而且还避免了植筋过程中应力集中带来质量和安全隐患。
