A kind of across base pit engineering conduit wiring suspension structure
Technical field
This utility model relates to conduit wiring suspension structure, particularly to one across base pit engineering conduit wiring suspension structure.
Background technology
Original various municipal pipelines inevitably will be brought extreme influence by subway work, to original planned and
Build pipeline layout to make troubles, pipeline move change and how problem to existing pipeline protection become the difficult problem in subway work it
One.The successful suspention experience that municipal construction is conventional, all uses Bailey bracket beam to be supported former suspension system.
Design requirement all can not be met because of former Pile Bearing Capacity and stability, therefore when second consolidation scheme is checked
Ignore former pile foundation stress, the gravity of former suspension system is fully relied on new Bailey bracket beam and supports, pass through through checking computations stressing conditions.
Bailey bracket beam monolithic a size of 3m length, 1.5m is high, and it is 0.45m that two panels Bailey bracket laterally couples size (i.e. array pitch).Bailey beam base
Seat uses φ 1200 drilled pile, and arrangement of reinforcement is with reference to dependency structure design reinforcement.Rock stake at end is met at the stake end.Consider that Bailey beam temperature deformation is stretched
The impact of contracting etc., Bailey beam bearing one end sets sliding support, one end sets hold-down support.Bearing uses φ 22 × 50 bolt by shellfish thunder
Beam support plate is connected on pedestal pre-embedded steel slab, and sliding support plate sets bar shaped bolt hole makes steelframe longitudinally can freely stretch.Shellfish
Lei Liang removes and just can need to carry out after pipeline is buried in the earth and stablizes.Therefore, pipeline must be positioned at below Bailey beam, admittedly should be by new shellfish
Lei Liang is placed between former Bailey beam and pipeline.Additionally, it is contemplated that in former suspension system along in the range of each 3m in structure longitudinal direction north and south,
Side slope is carried out injecting grout through steel perforated pipe reinforcing.
Using the scheme of Bailey bracket, when the situation that pipeline is less, can pass by the middle part of truss, the shortcoming of this scheme is
Bailey bracket cannot also serve as support.When pipeline diameter is bigger, be from the jacking of Bailey bracket top or bottom suspension protection scheme, this side
The shortcoming of case is in addition to Bailey bracket cannot also serve as support, because pipeline absolute altitude limits, and Bailey bracket scope Underground Construction difficulty, have
In the case of Xie, need to adjust organization plan.

This utility model purpose is to overcome the deficiencies in the prior art, a kind of across base pit engineering conduit wiring suspension structure,
Its constructing operation is convenient, and can protect pipeline well.
In order to achieve the above object, this utility model is by the following technical solutions:
A kind of across base pit engineering conduit wiring suspension structure, including: twice first concrete support, described first coagulation
Soil stays in the pipeline hole of overhead pipe;Twice first concrete support is parallel to each other and horizontally disposed;
Some linking beams, the two ends of described contact are separately fixed on twice first concrete support;
Support framework, the quantity of described support framework identical with the quantity of described linking beam and with described linking beam one a pair
Should;Described support framework includes two first shaped steel and one first girder steel;The upper end of two first shaped steel links described in being fixed on
The downside of beam, described first girder steel is fixed on the lower end of two first shaped steel.
As preferably, described first girder steel arranges curved plate bearing.
As preferably, floor of putting more energy into is set in described first shaped steel and described first girder steel.
As preferably, described in the put more energy into thickness of floor be 12mm.
As preferably, described first shaped steel is H profile steel, and described first girder steel is steel beam with box shape.
Compared with prior art, this utility model has the advantages that
By said structure, this utility model utilizes the first of deep-foundation pit engineering to support, and by setting up linking beam, both solves
Determine across the problem of foundation ditch pipeline protection, similar Bailey bracket will not have been produced again and invade the problem of structure roof, save simultaneously
Construction investment.

Detailed description of the invention
A kind of across base pit engineering conduit wiring suspension method, comprise the following steps:
S1, the building enclosure of construction pipeline 5 foundation ditch;In order to allow the most smooth and structural safety of construction, sinking of building enclosure
Slag thickness need to be less than 50mm.
S2, construction twice first concrete support 1, twice first concrete support 1 is parallel to each other and horizontally disposed;
S3, some linking beams 2 of constructing, the two ends of linking beam 2 are connected with twice first concrete support 1 respectively;And
The downside of linking beam 2 is provided with two H profile steel being parallel to each other;H profile steel is vertical with linking beam 2;
Soil in S4, excavation overhead pipe 5 foundation ditch, makes the elevation of overhead pipe 5 foundation ditch less than the absolute altitude bottom pipeline 5;
S5, connect a steel beam with box shape 32 in the lower end of two H profile steel;In order to allow pipeline 5 place more stable and to improve even
Connect rigidity, steel beam with box shape 32 arranges curved plate bearing.
S6, pipeline 5 is migrated in the framework that H profile steel 31 and steel beam with box shape 32 form.As shown in Figure 4, it is seen then that every company
The framework being all made up of with steel beam with box shape 32 H profile steel 31 below binder 2, and pipeline 5 is just through these frameworks, is placed on these
On the steel beam with box shape 32 of framework, i.e. the common support of these frameworks plays pipeline 5.
Arranging in H profile steel 31 and steel beam with box shape 32 and put more energy into floor 4, the floor 4 preferably thickness of putting more energy into of employing is put more energy into floor,
Concrete thickness is 12mm.
One described in the utility model across base pit engineering conduit wiring suspension structure, including:
Twice first concrete support 1, first concrete support 1 is located in the pipeline hole of overhead pipe 5;Twice
One concrete support 1 is parallel to each other and horizontally disposed;
Some linking beams 2, the two ends of contact are separately fixed on twice first concrete support 1;
Support framework, the quantity of support framework identical with the quantity of linking beam 2 and with linking beam 2 one_to_one corresponding;Support frame
Frame includes two H profile steel 31 and a steel beam with box shape 32;The upper end of two H profile steel 31 is fixed on the downside of linking beam 2, steel beam with box shape
32 lower ends being fixed on two H profile steel 31.In order to allow pipeline 5 place more stable and to improve coupling stiffness, on steel beam with box shape 32
Curved plate bearing is set.
Arranging floor 4 of putting more energy in H profile steel 31 and steel beam with box shape 32, the floor 4 preferably thickness of putting more energy into of employing is put more energy into floor, tool
Body thickness is 12mm.
This utility model utilizes the first of deep-foundation pit engineering to support, and by setting up linking beam 2, has both solved across foundation ditch
The problem of pipeline protection, will not produce again similar Bailey bracket and invade the problem of structure roof, save construction investment simultaneously.
