Construction method for using vertical buried pipe heat exchange pipe well as well point dewatering well in construction
The invention discloses a construction method for using a vertical buried pipe heat exchange pipe well as a well point dewatering well in construction. A well body is included, and the well body sequentially comprises a large-diameter section, a transition section and a small-diameter section from top to bottom; the depths of the large-diameter section and the transition section are matched with the depth of a well point downcast pipe; the construction method comprises the following specific construction steps: 1, drilling downwards from the earth surface to form a well body; 2, a heat conduction pipe with a U-shaped lower end is arranged in the well body; 3, the well body is filled with the mixture to fill the small-diameter section; 4, arranging a well point downcast pipe in the well body; 5, filling the well body with medium sand until the medium sand is 1 meter away from the ground surface; 6, filling cohesive soil in a range from the medium sand to the earth surface in the well body; and 7, before the foundation pit is excavated, dewatering work is carried out through a well point dewatering pipe arranged in the well body and corresponding well point dewatering equipment, and the height of the underground water level is reduced. The ground surface shallow layer section of the vertical buried pipe well is used as a well point dewatering well in the foundation pit excavation period, one well has two purposes, and the functions of two kinds of wells are achieved.
本发明公开了施工中将竖直地埋管换热管井作为井点降水井的施工方法，包括井体，井体从上向下依次包括大径段、过渡段和小径段；大径段和过渡段的深度与井点降水管匹配；施工步骤具体如下：1、从地表向下钻孔，形成井体；2、在井体内设置下端呈U形的导热管；3、向井体内填充混合料填满小径段；4、在井体内设置井点降水管；5、向井体内填充中砂，填充到距离地表1米的深度；6、在井体内，中砂至地表的范围填充黏性土；7、开挖基坑前，通过设置在井体内的井点降水管，以及相应的井点降水设备实施降水工作，降低地下水水位高度。本发明将竖直地埋管井的地表浅层段作为基坑开挖期间的井点降水井之用，实现一井两用，实现两种井的功能。
