Abstract

The invention discloses a supporting steel pipe device of an underground added layer of an existing building. The supporting steel pipe device comprises at least two steel pipes, every two adjacent steel pipes are connected with each other through a steel pipe joint and short pins, and a first plughole in which a long pin can be plugged is formed in the position, outside the range of the length of each steel pipe joint, at the upper end of each steel pipe; each steel pipe joint and every two adjacent steel pipes are provided with corresponding second plugholes in which the short pins can be plugged, and the first plughole and the second plugholes in each steel pipe are arranged by being staggered by 90 degrees. Meanwhile, the invention further discloses an installing method of the supporting steel pipe device. The supporting steel pipe device guarantees that the steel pipes bear force reasonably after being connected, achieves rapid and convenient connection of the steel pipes, shortens the time for inserting the steel pipes into boreholes, and lowers the risk of borehole collapse. Meanwhile, horizontal tied rod members can be installed conveniently, and stability of the steel pipes is guaranteed. The steel pipes can be recycled, so that engineering cost is lowered. Required hoisting equipment is portable, construction is applicable to basements and other narrow and small space, and technical support is provided for the underground added layer of the existing building.

Description

technical field [0001] The invention relates to a civil construction technology, in particular to a supporting steel pipe device and an installation method for an existing building's underground layer increase. Background technique [0002] Orderly, reasonable, comprehensive and efficient development and utilization of underground space resources of existing buildings has become one of the most effective ways to expand infrastructure capacity, improve urban comprehensive disaster prevention capabilities, improve land use efficiency and save land resources. According to the requirements of urban planning, most new buildings have considered the development and utilization of underground space. However, a large number of existing buildings have not designed underground parking lots due to historical reasons and lack of forward-looking. With the increase in the number of cars, it is difficult to park. Therefore, the development of the underground space of existing buildings is ...
