Problems solved by technology
[0002] The construction of the subway will inevitably have a great impact on the original various municipal pipelines, and bring inconvenience to the layout of the original planned and under-construction pipelines. One of the most difficult problems, improper pipeline protection methods can easily cause engineering accidents
[0003] The existing in-situ protection of pipelines all adopts the scheme of Bailey frame, but when the diameter of the pipeline is large, it is necessary to drag the roof from the upper part of the Bailey frame or suspend the protection of the pipeline from the lower part of the Bailey frame. Construction efficiency is low, there is still room for improvement

Embodiment Construction
[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0041] The invention discloses a method for suspending a pipeline 1 across a foundation pit, comprising the following steps:
[0042] S1. Excavate at least two first foundation pits arranged at intervals on the upper side of the box culvert 2. The width of the first foundation pit is greater than the width of the box culvert 2. The enclosure structure of the first foundation pit is constructed, and then the first foundation pit is constructed. The ring beam 5 is poured with concrete in the foundation pit. Two fixing plates 51 are pre-embedded on the upper side of the ring beam 5. The width of the ring beam 5 is greater than that of the box culvert 2. The length of the ring beam 5 protruding from both sides of the box culvert 2 is equal. The number of the first foundation pit can be selected according to the length of the pipeline 1 and the suspension force ca...

The invention relates to a suspension method and structure for a pipeline stretching across a foundation pit, and relates to the technical field of pipeline supporting. The suspension structure comprises a plurality of first supporting beams, at least two ring beams, load bearing beams, a suspension beam, suspension rods, first nuts and second nuts. The first supporting beams are arranged on the lower side of a box culvert, the ring beams are arranged on the upper side of the box culvert, the load bearing beams are fixed to the upper sides of the ring beams, and the suspension beam is fixed tothe load bearing beams. The suspension rods are arranged on the two sides of the box culvert, the lower ends of the suspension rods penetrate through the first supporting beams, and the upper ends ofthe suspension rods penetrate through the suspension beams. The first nuts are connected to the suspension rods in a threaded mode and arranged on the upper sides of the suspension beams, and the second nuts are connected to the suspension rods in a threaded mode and abut against the lower sides of the first supporting beams in a connection mode. The two sides of each ring beam stretch out of thetwo sides of the box culvert, and the at least two ring beams are arranged in a separated mode. The suspension method and structure for the pipeline stretching across the foundation pit have the advantages of being simple in structure and convenient to construct and improving the construction efficiency of pipeline suspension.
Description
technical field [0001] The invention relates to the technical field of pipeline support, in particular to a suspension method and a suspension structure for a pipeline across a foundation pit. Background technique [0002] The construction of the subway will inevitably have a great impact on the original various municipal pipelines, and bring inconvenience to the layout of the original planned and under-construction pipelines. One of the most difficult problems is that improper pipeline protection methods can easily cause engineering accidents. [0003] The existing in-situ protection of pipelines all adopts the scheme of Bailey frame, but when the diameter of the pipeline is large, it is necessary to drag the roof from the upper part of the Bailey frame or suspend the protection of the pipeline from the lower part. The construction of the underground structure within the Bailey frame is difficult, resulting The construction efficiency is low, and there is room for improvem...
