Abstract
The utility model discloses an in-situ protection structure for pipelines above a foundation pit. The in-situ protection structure comprises a truss, steel vertical columns, upper template beams, lower template beams, a wrapping barrel, chain blocks and steep wire ropes. The truss stretches across a pipeline box culvert and is horizontally arranged, the steel vertical columns are arranged at both ends of the truss, the upper template beams are transversely supported by the top of the truss, the upper template beams and the lower template beams correspond to each other one to one, the lower template beams are supported by the bottom of the wrapping barrel, the wrapping barrel wraps the periphery of the pipeline box culvert, and the lower template beams and the lower template beams are connected with the steel wire ropes through the chain blocks. According to the in-situ protection structure, settlement deformation of the pipeline box culvert in the construction process of the foundation pit can be avoided, and therefore in-situ protection of the pipelines is achieved. It can be guaranteed that the settlement deformation value of important pipelines without moving and modifying conditions within the construction range of the foundation pit is not more than an allowable value, and the influences on a foundation pit support structure and a main structure are within a controllable range.
Description
Technical field
The utility model relates to a kind of in-situ conservation structure of pipeline, particularly relates to the in-situ conservation structure of a kind of foundation ditch top pipeline.
Background technique
At present, in carrying out the foundation pit construction process of track traffic and building construction, city proper can run into a large amount of shallow embedding municipal pipelines, these municipal pipeline buried depths are generally in 2m left and right, can affect the construction of foundation pit enclosure structure, earth excavation and agent structure, at present mainly taking to move the method changing solves, temporarily pipeline is changed and adjourned construction area from construction infection region, after foundation pit construction all completes, then pipeline is moved and changes back original position.But at foundation ditch narrow field or pipeline is extremely important and do not possess the situation of moving the condition of changing to distortion sedimentation is very responsive etc. around, just need to carry out in-situ conservation to pipeline.Take which kind of structural type can guarantee that pipe settlement distortion meets the demands, can accomplish economical rationality again, easy construction, does not also have ripe technological scheme at present.
Summary of the invention
The utility model provides the in-situ conservation structure of a kind of foundation ditch top pipeline for solving the technical problem existing in known technology.
The technological scheme that the utility model is taked for the technical problem existing in solution known technology is: the in-situ conservation structure of a kind of foundation ditch top pipeline, comprise truss, steel column, top bearing beam, bottom bearing beam, parcel cylinder, jack and wire rope, described truss is across on pipeline box culvert and horizontal arrangement, the two ends of described truss are equipped with described steel column, the top cross-arm of described truss has described top bearing beam, described top bearing beam is relative one by one with described bottom bearing beam, described bottom bearing beam is supported on the bottom of described parcel cylinder, described parcel cylinder is wrapped in the surrounding of pipeline box culvert, described bottom bearing beam is connected with wire rope by jack with described top bearing beam.
The two ends of described truss are respectively provided with two described steel columns, have set up middle part bearing beam on these two described steel columns, and described erection of truss is on two relative described middle part bearing beams.
Described truss two ends bottom welding has pressure-bearing steel plate.
Advantage and the good effect that the utlity model has are: adopt steel column sub-truss; the structure that truss suspends protected pipeline box culvert in midair by wire rope and jack; can avoid pipeline box culvert generation sedimentation and deformation in foundation pit construction process, thereby realize the in-situ conservation of pipeline.Can guarantee not possess within the scope of foundation pit construction the important pipe settlement deformation values that moves the condition of changing and be no more than permitted value; and the impact of foundation pit enclosure structure and agent structure, in controlled range, is applicable to the in-situ conservation of top pipeline in the foundation pit construction processes such as underground station, construction of underground structure, building construction.

Embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1～Fig. 3, the in-situ conservation structure of a kind of foundation ditch top pipeline, comprise truss 3, steel column 5, top bearing beam 2, bottom bearing beam 7, parcel cylinder 9, jack 10 and wire rope 6, described truss 3 is across on pipeline box culvert 8 and horizontal arrangement, the two ends of described truss are equipped with described steel column 5, the top cross-arm of described truss 3 has described top bearing beam 2, described top bearing beam 2 is relative one by one with described bottom bearing beam 7, described bottom bearing beam 7 is supported on the bottom of described parcel cylinder 9, described parcel cylinder 9 is wrapped in the surrounding of pipeline box culvert 8, described bottom bearing beam 7 is connected with wire rope 6 by jack 10 with described top bearing beam 2.
In the present embodiment, in order to guarantee the stable of Steel Truss integral body, be respectively provided with two described steel columns 5 at the two ends of described truss 3, set up middle part bearing beam 4 on these two described steel columns 5, described truss 3 is erected on two relative described middle part bearing beams 4.In order to improve the local anti-pressure ability of truss, at described truss two ends, bottom welding has pressure-bearing steel plate 1.
After foundation pit construction completes, should carry out in time soil body backfill and the recovery of pipeline box culvert.After the backfill of pipeline box culvert completes, remove the members such as above-mentioned truss 3 and steel column 5.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, can also make a lot of forms, within these all belong to protection domain of the present utility model.
