Description
Technical field
The present invention relates to building engineering field, and in particular to the foundation ditch in the field such as underground engineering, hydraulic engineering, municipal works
Bracing Systems.
Background technology
Urban Underground Space Excavation has turned into long-term emphasis investment construction field in country, is produced in development process substantial amounts of
Base pit engineering.Riverine and coastal Soft Deep Foundation Pit engineering using Shanghai, Tianjin, Wuhan, Nanjing as representative is largely enclosed using board-like
The support system of protection structure combination inner supporting structure, wherein the deadweight of horizontal inner supporting structure and construction loads mainly use steel lattice
The vertical support system of structure post combination cast-in-situ bored pile undertakes.To ensure that the stability of steel lattice column and vertical load effectively pass
Cast-in-situ bored pile is handed to, steel lattice column is commonly inserted below the effective stake top of cast-in-situ bored pile 2 ~ 3 meters.And bored pile construction produces
Raw substantial amounts of discarded slurry, produces serious problem of environmental pollution；Because pile concrete is strong using underwater cast-in-place perfusion, pile body
Spend low, construction quality is difficult to control, and collapse hole, necking down, pile bottom sediment turn into the major defect of bored concrete pile；In addition cast-in-situ bored pile is applied
Work speed is slow, efficiency is low, cost is high.In order to adapt to the growth requirement of new period building industrialization and energy-saving and emission-reduction, prefabricated pile is planted
Stake technology turns into a green pile foundation technology with broad prospect of application.The Integration ofTechnology cast-in-situ bored pile, deep-layer stirring
The advantages of technologies such as stake, drilling base expanding and base expanding, prefabricated pile, compared to conventional borehole bored concrete pile, mud emission reduces more than 80%, concrete
Dosage reduces more than 60%；Without squeezing soil compared to traditional prefabricated pile, noise is small, and application is wider.But current prefabricated pile plants stake skill
Art is mainly used in agent structure foundation engineering, and as foundation ditch stand column pile then need to solve vertical support steel lattice column with it is pre-
Effective connectivity problem of stake processed, so that it is guaranteed that steel lattice column undertakes effective transmission and the stability of load.
The content of the invention
The technical problems to be solved by the invention are that the assembling for how realizing steel lattice column and prefabricated pile connects, so that will
The steel lattice column and prefabricated pile of factorial praluction ensure that steel lattice column undertakes load as base pit engineering vertical support structure
Effectively transmission and stability.
To be connect in order to solve the above technical problems, the invention provides the connection of a kind of vertical support steel lattice column and prefabricated pile
Head, technical scheme are：Joint is arranged between steel lattice column and prefabricated pile；Joint is by square-section metal sheet pile and positioned at square section
The joint steel loop plate of face metal sheet pile bottom surface is mutually permanently connected to be formed；The vertical angle steel of steel lattice column corner is close to be nested in square
On the outside of the corner of section metal sheet pile, angle steel is connected with the neighboring area full weld that square-section metal sheet pile is bonded；The stake top of prefabricated pile
Steel loop plate is fixed with joint steel loop plate to be docked.
Beneficial effects of the present invention are：Steel lattice column and prefabricated pile pass through factorial praluction, reliable in quality；Scene passes through
The mode of assembling is constructed, and work efficiency improves；Compared to traditional vertical support system, the length of steel lattice column reduces 2 ~ 3m, column
Stake mud emission reduces more than 80%, and concrete amount reduces more than 60%.The present invention realizes the work of foundation ditch vertical support structure
Factory's metaplasia production and prefabricated construction, will promote the development of building trade green construction technology, and energy-saving and emission-reduction and protection are realized in promotion
The target of ecological environment.
Soft Deep Foundation Pit engineering uses the board-like supporting type gone along with sb. to guard him with reference to inner support more, and the present invention realizes steel pile
The vertical support structure to form inner support is connected by factorial praluction, assembling with prefabricated pile, base pit engineering industry will be promoted
Change the development of support technology, realize the target of energy-saving and emission-reduction.
Brief description of the drawings
Below in conjunction with the accompanying drawings and application method the invention will be further described.
Fig. 1 is vertical support steel lattice column and prefabricated pile connection diagram.
Fig. 2 is vertical support steel lattice column and prefabricated pile jointing organigram.
Embodiment
The present invention carries out assembling with prefabricated pile to steel lattice column by a kind of shaped steel jointing and is connected, so as to be used as base
The vertical support structure of engineering level support is cheated, is realized using prefabricated pile as base pit engineering stand column pile.With reference to accompanying drawing, specifically retouch
State as follows：
As depicted in figs. 1 and 2, prefabricated pile 3 is being transferred to setting absolute altitude, erection joint 1, by joint steel loop plate 4 and prefabricated
The periphery of stake top steel loop plate 5 of stake is welded to connect integrally, then lifts steel lattice column 2, four angle steel nestings of steel lattice column 2 again
In the outside of the square-section metal sheet pile of joint 1, angle steel is connected with the neighboring area full weld that square-section metal sheet pile is bonded.Or
First steel lattice column 2 and joint 1 are welded as a whole, then are attached with prefabricated pile 3.
Joint 1 is formed by the square-section metal sheet pile of epimere and the joint steel loop plate weld of lower end, square-section metal sheet pile
Four sides outside and the intersection corner region of joint steel loop plate 4 set three pieces of steel ribs per side, steel ribs and square-section metal sheet pile and
Together, the connected mode in figure is only a kind of signal to joint steel loop plate weld, can also take other prior art measure handles
Square-section metal sheet pile and joint steel loop plate are mutually permanently connected；Four angle steel of steel lattice column 2 are close to be nested in the epimere of joint 1
The outside of square-section metal sheet pile corner, nested lengths are calculated according to load requirement；The stake top steel loop plate 5 of prefabricated pile is with connecing
The joint steel loop plate 4 of first 1 lower end docks, and upper and lower two parts steel loop plate carries out full weld connection after being adjacent to border abutment joint, certainly
Other prior arts can also be taken to complete being fixedly connected for stake top steel loop plates and joint steel loop plate.The present invention is by joint by steel
Lattice column 2 and the assembly connection of prefabricated pile 3 are integrated, the new vertical supporting structure as base pit engineering support system.
The practical scheme provided of the invention is discussed in detail above, for those of ordinary skill in the art, according to this
The thought of inventive embodiments, in specific embodiments and applications there will be changes.In summary, in this specification
Appearance should not be construed as limiting the invention, and all any changes made according to design philosophy of the present invention are all in the protection model of the present invention
Within enclosing.
