Develop rapidly.The application of deep basal pit inner support technology will not only ensure the stabilization of side slope, and meet wanting for Deformation control
Ask, to ensure the safety such as the building around foundation ditch, underground utilities, road.In recent years, deep pit digging support issues are increasingly dashed forward
Go out, thus deep pit digging supporting and the influence to adjacent building, road and facility are increasingly that engineers are of interest.It is existing
The conventional one kind of Brace in Deep Footing Groove is reinforced concrete support；Another is steel pipe inner supporting, its advantage：From heavy and light, beneficial to applying
Work, low cost, recoverable, environmental protection, shortcoming：Rigidity is small, and easy unstability is, it is necessary to which vertical levels are supported.But foundation ditch is opened
Dig depth more and more deeper, excavation environment is increasingly complicated, the problem of design and construction personnel frequently encounter new and new challenge, so that
Making the success rate of base pit engineering reduces.How a kind of safety and stability that both can guarantee that during deep pit construction of optimum choice
Property, the deep foundation pit supporting structure scheme of good economic benefit can be obtained again, be all that the primary of base pit engineering research is asked all the time
Topic.Meanwhile, the deep-foundation pit engineering in city excavates the influence for requiring that strict control is excavated to surrounding environment.Therefore consider
The each side such as safety, economy and environmental evaluation factor explores optimization design of foundation pit supporting method, solves deep pit digging and causes
Urban Environmental Geology Problems undoubtedly there is important theory significance and engineering practice to be worth.
The content of the invention
There is provided one kind for the safety and stability and Cost Problems that solve deep pit construction process for the utility model
With the double Pin large diameter steel pipe inner support beams of layer.
The utility model adopts the following technical scheme that realization：
With the double Pin large diameter steel pipe inner support beams of layer, indulged by some parallel horizontal double steel pipe groups of same layer with some parallel
Formed to double steel pipe group interconnection, be groined type node at interconnection, the concrete composition component of inner support beam is including two-way
Two-tube cross integral joint, straight shaped steel pipeline section and regulation leg, each ends are bolted by mounting flange,
Groined type node is combined using two cross integral joints of two-way, two-pipe, and inner support beam end is the tune being connected with waist rail
Save leg.
The cross integral joint of described two-way, two-pipe intersects interlocking by a steel pipe with two perpendicular steel pipes, whole
Body structure is bi-directional symmetrical, and the channel-section steel that intersecting the intra-node of interlocking has square crossing is strengthened, and the node four for intersecting interlocking is outer
Portion angle is provided with ring flange provided with steel plate rib, each end of steel pipe is strengthened, and ring flange medial surface is connected with steel tube head full weld, method
Blue disk extension ring portion medial surface is evenly equipped with floor with outer wall of steel pipe, and ring flange extension ring portion is provided with coupling bolt hole.
Described straight shaped steel pipeline section is that a straight section steel pipe two ends are provided with ring flange, ring flange medial surface and steel tube head full weld
Connection, ring flange extension ring portion medial surface and outer wall of steel pipe are evenly equipped with floor, and straight shaped steel pipeline section is divided into standard paragraphs, regulation section, non-
Standard paragraphs, standard segment length has 1 meter and 4 meters of long segments, and regulation segment length has 0.25 meter and 0.5 meter of long stage, and non-standard segment is
The section of length needed for individually formulating as needed.
The utility model has the advantages that compared with the prior art：Optimize inner supporting structure, steel pipe support dismounting
It is convenient, construction period is shortened, prefabrication reduces construction cost, and steel pipe support is adapted to different size of base
Hole, can be reused；The inner support of combining form can be constituted with reinforced concrete support and steel pipe support, if for facing
Nearly existing line deep foundation pit construction, reduces the influence to existing line.Therefore the utility model is super suitable for subgrade deep basal pit
The construction of deep subterranean excavation；It is closer to and earthwork work suitable for being embedded with pipeline, surrounding building high to environmental requirement around foundation ditch
Phase urgent foundation pit construction；The foundation ditch of lifting can not be supported in place suitable for loop wheel machine；Suitable for foundation ditch periphery narrow space,
Lack the stacking place as material and plant equipment.
