Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0035] A method for constructing an underground space with a pipe shed under an old building, carried out in accordance with the following steps:

[0036] 1) Select at least two locations next to the building that needs to excavate the underground space that are suitable for making entrances or less disturbing to the use of the building (such as open spaces with little vegetation; such as figure 2 shown).

[0037] 2) At this location, excavate at least two working wells 1 or ramps; the cross-sectional size of the working wells or ramps is generally not less than 7 meters x 7 meters (such as image 3 shown), the depth of the working well or ramp must reach the bottom of the underground space below one meter;

[0038] 3) According to the calibrated position of the underground space (that is, the horizontal projection outline 13 of the underground sp...

Abstract

The invention relates to a method for building an underground room under an old building by using pipe sheds, which aims to provide a method which has the characteristics that the construction period is short, the construction size is small and the construction can avoid the underground pipelines. The invention adopts the technical scheme that the method includes the following steps: 1) determining the positions of at least two entrances and exits beside the building; 2) digging work shafts or access ramps at the positions; 3) striking a plurality of steel pipes into each work shaft or access ramp and pouring in cement slurry; 4) digging a horizontally extended construction channel between the steel pipes; 5) striking a plurality of steel pipes into the construction channel; 6) continuing to strike a plurality of steel pipes among the pipe sheds in the construction channel to form a steel pipe wall; 7) cutting earth within the range among the pipe sheds; 8) after the underground room is dig out, welding steel plates or channel steel at the outer side of the pipe shed wall for reinforcement; 9) integrating the pile foundations of the old building; and 10) transforming the work shafts to elevator shafts and transforming the access ramps to entrance / exit ramps.

Description

technical field [0001] The invention relates to a construction method, in particular to a construction method for an underground space. Background technique [0002] With the rapid development of economic construction, more and more buildings are being expanded to high altitude and underground; Restrictions have affected the development of underground buildings. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned deficiencies in the background technology, and provide an improvement of a method for constructing an underground space. This method has the characteristics of short construction period, small construction scale, distance from underground pipelines, and the ability to ensure that the original vegetation on the ground is intact. And the construction cost is lower. [0004] The technical solution provided by the invention is: a method for building an underground space with a pipe shed un...
