Double-sleeve artesian deep well dewatering construction method and structure for muddy silty clay silty soil
The invention belongs to the technical field of building construction, and particularly relates to a double-sleeve artesian deep well dewatering construction method for muddy silty clay silty soil. The double-sleeve artesian deep well dewatering construction method comprises the following steps of (1) measuring and positioning a deep well, digging a pit and detecting an obstacle; (2) deep well hole forming; (3) lowering a coarse filter pipe and filling the coarse filter pipe with a coarse filter material; (4) well washing; (5) lowering a fine filter pipe and filling the fine filter pipe with afine filter material; (6) trial precipitation; (7) implementing precipitation; and (8) plugging a tube well. The method has the beneficial effects that firstly, soil property parameter characteristics are defined through geological exploration, and it can be ensured that underground water can well permeate into the deep well and clean water basically flows into the well by adopting a double-filtering measure of combining the coarse filter pipe and the fine filter pipe; the precipitation effect is effectively guaranteed, and the good precipitation effect is shown in the two aspects of large water yield and clear water discharge; and the defects of small water yield, turbid effluent and the like in the prior art are overcome, and it can be ensured that deep well precipitation meets the design and construction requirements.
本发明属于建筑施工技术领域，具体涉及一种淤泥质粉质粘土夹粉土地质的双套管自流深井降水施工方法，包括以下步骤：(1)深井测量定位及挖坑探障；(2)深井成孔；(3)下放粗滤管及灌填粗滤料；(4)洗井；(5)下放细滤管及灌填细滤料；(6)试降水；(7)实施降水；(8)管井封堵。本发明首先通过地质勘探明确土质参数特性，采用粗滤管和细滤管相结合的双重过滤措施，确保地下水不仅能够较好地渗透到深井，而且使得自流到井内的基本是清水；有效保证降水效果，良好的降水效果表现在出水量大与出清水两方面；解决出水量小、出水浑浊等现有技术中的不足，能够确保深井降水满足设计及施工要求。
