Embodiment
[0017] as attached figure 1 Shown: a construction method for pressure relief of lead holes in existing buildings, including the following steps:
[0018] S101. Use stainless steel pipes, flanges, and blind plates to prefabricate the bonded pipe 5 for the drainage and pressure relief of the existing building; the production method of the bonded pipe 5 is to use argon arc welding of multiple stainless steel pipes, and its length depends on the building floor. 2 The thickness should be adjusted, but should not be less than 15cm; single-sided welding is used between the welded stainless steel pipe and the chassis of the flange to meet the connection strength requirements; double-sided full welding is used between the stainless steel pipe and the chassis of the flange , need to meet the connection strength and waterproof requirements. Bolts are used between the flange and the blind plate, and a gasket is installed between the two.
[0019] S102. Excavate the pit 1 on the building...

The invention discloses a guide hole pressure relief construction method for an existing building, and particularly relates to the technical field of building construction. The guide hole pressure relief construction method of the existing building comprises the following steps that a stainless steel pipeline, a flange plate and a blind plate are adopted to prefabricate a bonding pipe; a pit slot is dug in the building bottom plate, and a primary hole is drilled in the pit slot through a water milling drilling machine; the bonding pipe and the primary hole are fully coated with water-resistant reinforced epoxy resin, and the bonding pipe and the primary hole are bonded together; the water milling drilling machine penetrates through the bonding pipe and performs secondary drilling on the primary hole, then the water milling drilling machine is removed, and a pipe opening of the bonding pipe is closed after clear water flows out of the drilled hole; and meanwhile, the pit slot and the bonding pipe are enclosed into a maintenance chamber by using a steel plate. By adopting the technical scheme of the guide hole pressure relief construction method for the existing building, the problem of anti-floating instability of the existing building is solved, the guide hole pressure relief construction method can be used for rapid pressure relief operation when the existing building is unstable, and meanwhile, the guide hole pressure relief construction method for an existing building can be used as a long-term or temporary water-resistant plate guide hole drainage pressure relief method for the existing building.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for pressure relief of lead holes in existing buildings. Background technique [0002] In recent years, with the development of urban underground space, a large number of square-style buildings with large-scale underground buildings have sprung up. The problem of anti-floating of underground buildings has become more prominent, and related damage cases have emerged in endlessly. When the existing buildings appear anti-floating instability, how to quickly and effectively solve it becomes the focus of attention. Conventional treatment measures such as ballasting, adding anti-floating anchors, and uplift piles have problems such as high construction costs, long periods, dewatering construction, and large impact on the surrounding environment. It is urgent to develop a new construction method for pressure relief of pilot holes , to achieve the pur...
