Background

The horseback is commonly used in pipeline engineering implemented by a non-excavation method, and is an inspection well built on a main pipeline. The use of the horseback well increases the implementation length of a non-excavation method, and reduces the influence of construction on the surrounding environment such as municipal roads, pipelines and the like.

The general way of riding the horse well at present is: in the non-excavation method implementation process, a special pipe joint is adopted to replace a part of common pipe joints, and the special pipe joint is generally provided with an outer-wrapped steel plate; then, supporting and retaining soil by adopting an open cut or steel casing mode, revealing the special pipe joint, and welding the steel casing and an outer steel plate together; and finally, building a reinforced concrete inspection well and accessory facilities in the steel casing. The construction of the conventional horseback riding well can be implemented by meeting the conditions that the diameter of a main pipe reaches a certain size, and the position of a special pipe joint needs to be preset.

With the continuous development of urban construction, the trenchless method is more and more likely to encounter underground pipelines and obstacles in the implementation process. Under the influence of such external conditions, the trenchless approach is forced to be stopped, which may occur when an inspection well is newly added to the implemented pipeline. And when the pipe diameter of the main pipe is smaller, the construction mode of the conventional horse riding well cannot meet the requirement.
