Tube well overhanging protection structure and brickwork tube well in-situ protection construction method

Abstract

The invention provides a tube well overhanging protection structure. The tube well overhanging protection structure comprises an inner hanger plate traction part, an outer hanger plate traction part,a spandrel girder, inner hanger plates for being connected with the inner side wall of a tube well, and outer hanger plates for being connected with the outer side wall of the tube well. The spandrelgirder is located above the inner hanger plate. The inner hanger plate traction part is wound around the spandrel girder. The inner hanger plates are hung at the two ends of the inner hanger plate traction part correspondingly. The outer hanger plate traction part is wound around the spandrel girder, and the outer hanger plates are hung at the two ends of the outer hanger plate traction part correspondingly. According to the tube well overhanging protection structure, the overall structure of the brickwork tube well can be effectively protected in the process of openly cutting a foundation trench brickwork tube well in a complex environment, and cracking of the brickwork tube well is effectively avoided to improve construction convenience and safety. The invention further provides a brickwork tube well in-situ protection construction method.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a tube well suspension protection structure and a construction method for masonry tube well in-situ protection. Background technique [0002] During the construction of underground passages, traffic evacuation and pipeline relocation are generally considered. Pipelines are generally relocated before construction. Suspended for protection. [0003] In the process of conventional pipeline relocation, it is necessary to set up pipeline wells connected to new pipelines and set up new pipelines. After the completion of new pipelines, stop the operation of existing pipelines and start new pipelines. During this process, new pipeline wells and pipelines need to be built. Time, Space, manpower and material resources are consumed. At the same time, since the tube well is usually connected to multiple pipelines, if the pipeline is relocated, it will cause problems such as...

[0003] In the process of conventional pipeline relocation, it is necessary to set up pipeline wells connected to new pipelines and set up new pipelines. After the completion of new pipelines, stop the operation of existing pipelines and start new pipelines. During this process, new pipeline wells and pipelines need to be built. Time, The consumption of space, manpower and material resources is relatively large. At the same time, since the tube well is usually connected with multiple pipelines, if the pipeline is relocated, the construction period will be long and the project cost will be high.

[0004] In the conventional process of suspending and protecting tube wells, external suspension is often used for the suspension protection of pipelines. However, there are few cases of protection of masonry tube wells for rainwater and sewage in domestic foundation pit projects, so the external suspension of pipelines is often used. Applied to tube wells, however, different tube well materials lead to different suspension schemes. Since the masonry structure is a structure that is not subject to tension and shear under pressure, it is necessary to adopt a reasonable suspension protection scheme according to the mechanical properties and engineering characteristics of the masonry structure. If the masonry tube well is directly suspended externally and then excavated, it is easy to ignore the characteristics of the masonry tube well, resulting in cracking of the masonry tube well, or even structural damage, loss of use function of the masonry tube well, and delay in the construction period
