Bearing platform for heating pipe channels to stride reserved subway station and construction method thereof

Abstract

The invention discloses a construction method of a bearing platform for heating pipe channels to stride a reserved subway station. The bearing platform comprises a platform plate and stand columns which support the platform plate; the bearing platform supports lower portions of heating pipes; guard piles and a waterproof curtain surround the periphery of the bearing platform; the height of the platform plate of the bearing platform coincides with that of a top mark of the reserved subway station; the stand columns which are steel structured lattice columns comprise portions which are reserved above a bottom line of a foundation ditch of the reserved subway station and portions which are reserved under the bottom line of the foundation ditch of the reserved subway station; the stand column portions which are reserved under the bottom line of the foundation ditch of the reserved subway station are inserted in reinforcement cages inside the piles and are combined into a whole through concrete pouring. The bearing platform is simple in structure and convenient to construct and enables later subway station construction to be normally operated under the platform due to the fact that the bearing platform is arranged under the heating pipes and the construction is not influenced by the front constructed heating pipes, does not influence safe quality of the heating pipes and provides favorable reference for similar intersection problem of underground engineering.

Description

technical field [0001] The invention relates to an underground thermal pipeline support structure and a construction method thereof. Background technique [0002] With the rapid development of underground construction projects, the difficulties encountered in the construction of underground crossing projects are also increasing. The uncertainty of geological conditions and the complexity of the site environment determine the difficulty and danger of project construction. How to solve the project During the implementation process, the intersection of pipelines and other important structures or reserved structures, how to ensure the smooth progress of the project is a difficult problem often encountered in the construction of underground projects. , The intersection of the thermal pipeline and the reserved subway station brings great difficulty to the construction, affects the work progress and reduces the work efficiency, and after the construction of the thermal pipeline st...
