High-ductility wall-building protection underground reservoir artificial dam body structure and construction method thereof
The invention relates to a high-ductility wall-building protection underground reservoir artificial dam body structure and a construction method thereof. The inner side and the outer side of a dam body are each provided with protection building blocks in a built mode to form two protection walls, the protection building blocks are prepared from high-ductility cement mortar, each protection building block is of a hollow structure, vertical steel bars and intra-wall tie bars are arranged in the hollow cores of the two protection walls in the longitudinal direction and the transverse direction respectively, then the hollow cores are filled with the high-ductility cement mortar, and the two protection walls are connected by hooking the vertical steel bars on the same layer in the two protection walls through inter-wall tie bars; and concrete is poured between the two protection walls to form a concrete interlayer, so that the artificial dam body structure is formed. According to the structure and the method, the construction difficulty in a narrow channel of a coal mine is reduced, the complex construction process of an impervious layer of a traditional artificial dam is simplified, the problem of synchronous construction of two different materials of an impervious wall and common concrete is solved, and the effects of seepage resistance, reinforcement, coordinated deformation anddam body durability improvement are achieved.
本发明涉及一种高延性砌墙防护地下水库人工坝体结构及其建造方法，在坝体的内外两侧分别砌筑防护砌块，形成两道防护墙，所述防护砌块采用高延性水泥砂浆制备而成，且防护砌块为空芯构造，在两道防护墙的空芯内纵向和横向分别配置竖向钢筋和墙内拉结筋，并以高延性水泥砂浆填充，两道防护墙之间通过墙间拉结筋钩住两道防护墙内同层的竖向钢筋进行连接；在两道防护墙间浇筑混凝土成为混凝土夹层，从而形成人工坝体结构。本发明降低了煤矿狭小通道内的施工难度，简化了传统人工坝防渗层复杂的施工工序，解决了防渗墙与普通混凝土两种不同材料的同步施工问题，起到抗渗、加固、协调变形、提高坝体耐久性的作用。
