Construction method of riding well on existing shield drainage pipeline
The invention provides a construction method of a riding well on an existing shield drainage pipeline. The construction method comprises that step 1: a foundation pit retaining structure is constructed on a foundation pit to be excavated, and the bottom of the foundation pit is paved with a shield pipeline; step 2: the foundation pit is divided into at least one section, if the foundation pit is divided into one section, the foundation pit is excavated until a set pit bottom elevation position is reached, and side walls and a base plate of the foundation pit are poured; if the foundation pit is divided into a plurality of sections, sections before the final section are excavated, then the final section is excavated until a set pit bottom elevation position is reached, the base plate of the foundation pit is poured, then the side walls of the final section are poured; step 3: a top pipe communicated with a well chamber is arranged, and a first hole is arranged in the base plate of the foundation pit and the top of the shield pipeline through a diamond barrel saw drilling machine; step 4: a top plate provided with a second hole is arranged on the top of the well chamber; and step 5: a well shaft and a well lid are arranged on the top plate. According to the invention, the riding well is arranged on the existing shield drainage pipeline, top sealing pipe pieces is removed by means of a static force cutting method, and the construction method is simple to implement, low in cost and high in safety.
