Tailing pond culvert pipe segmented grouting construction device and construction method thereof
The invention relates to the field of culvert pipe construction, in particular to a tailing pond culvert pipe segmented grouting construction device and a construction method thereof. The technical problems that the texture of a soil layer of the tailing pond is loose, if bubbles are not discharged in time in the grouting period, the structural strength of a culvert pipe supporting hole body is prone to being insufficient, and damage and even fracture of the culvert pipe are caused when the soil layer collapses are solved. The segmented grouting construction device for the tailings pond culvert pipe comprises a punching assembly, an annular frame and the like. The annular frame is connected with a punching assembly. A plurality of holes are formed in a hole body of a stratum in advance, then an arc-shaped pressing plate is supported by an expansion air cushion, meanwhile, slurry is jetted to the inner wall of the hole body, the slurry is squeezed to be injected into the holes formed in the inner wall of the hole body in advance, a formed culvert pipe is tightly combined with the surrounding soil layer, meanwhile, high-temperature gas is injected into the expansion air cushion, and the high-temperature gas is injected into the expansion air cushion. And bubbles in the slurry are absorbed outwards in time through the expansion air cushion and the central column.
本发明涉及涵管施工领域，尤其涉及一种尾矿库涵管分段注浆施工装置及其施工方法。为了解决尾矿库的土层质地疏松，并且在注浆期间若不及时将气泡排出，易导致涵管支撑洞体的结构强度不足，在土层坍塌时造成涵管的破损甚至断裂的技术问题。本发明提供了这样一种尾矿库涵管分段注浆施工装置，包括有打孔组件和环形架等；环形架上连接有打孔组件。本发明预先在地层的洞体上打设多个孔洞，再由膨胀气垫将弧形压板撑起，同时向洞体内壁喷注浆料，使浆料受到挤压而被注入洞体内壁预先打设的孔洞中，让形成的涵管与其周围的土层紧密结合，同时膨胀气垫内注入有高温气体，使浆料中的气泡及时通过膨胀气垫和中心柱被向外吸除。
