Construction method for constructing engineering dam in karst landform
The invention discloses a construction method for constructing an engineering dam in a karst landform. The construction method comprises the following steps that a, a gully where water flow flows through in a concentrated mode is selected, and no underground river or water flow channel exists underground through the geophysical prospecting and drilling technology; b, dam foundations are arranged at the positions, with small distances, of the two sides of the gully and located on the downstream of the gully in the step a, and the depth and the width of the dam foundations are determined through the underground hydrodynamics; c, holes are drilled and grooves are formed in the dam foundations in the step b, and then piling and column erecting are conducted in the grooves; d, quick-setting concrete is poured into the dam foundations where the piling and column erecting are conducted in the step c, and dam bases are formed after the quick-setting concrete is solidified; and e, finished bricks are used for building the front sides and the rear sides of the dam bases. By means of the construction method, the problem of qualitative, positioning and quantitative surveying of a complex seepage field of a karst depression can be simply, conveniently and effectively solved, and effective blocking of deep and large pipelines in the seepage field is avoided.
本发明公开了一种在喀斯特地貌建设工程水坝的施工方法，包括以下步骤：a.选取水流集中流过的沟壑山谷，通过物探、钻探技术确保地下没有暗河及水流通道；b.在步骤a所述的沟壑山谷下游，在沟壑山谷两侧距离较小的位置开设坝基，坝基的深度及宽度通过地下水动力学确定；c.在步骤b所述的坝基内部钻孔开槽，随后在槽内进行打桩立柱；d.在步骤c已打桩立柱的坝基内部采用快凝混凝土进行灌注，凝固后形成坝基座；e.利用成品砖在坝基座前后两侧进行砌筑。通过本申请的施工方法，能够简便有效的解决喀斯特洼地复杂渗流场定性、定位、定量勘测的问题，避开渗流场中深大管道的有效封堵。
