Description
Technical field
This utility model relates to the realm of building construction, and specific design one extension type support with manually dug piles constructs.
Background technology
In order to ensure construction safety during artificial digging pile, preventing the hole wall soil body from caving in, cause personal injury accidents, conventional stake holes method for protecting support has steel form method, fixing steel pile casting, concrete guard ring etc..Steel form method is a good steel form in digging stake holes, bar-mat reinforcement after-pouring concrete guard wall is inserted in colligation, the supporting excavation earthwork and casting concrete amount are relatively big, can again excavate, it is impossible to work continuously after concrete initial set to be treated, time interval is long, easily causing hydrops at the bottom of hole, soil body north maceration intensity reduces affects again bottom supporting safety, uses and easily cause periphery foundation deformation in Udoll layer, owing to effect is relatively low, digging process easily produces stake holes and ground hidden danger；Fixing steel pile casting is only applicable to shallow-layer and protects the pile of stake mouth; often have space to need on ground between casing and soil layer to be fixed against; it is difficult to again sink when steel pile casting is produced frictional resistance large force if soil layer deformation is caved in; its subject matter is only supporting aperture section; it is difficult to protect to deep, is difficult to carry out particularly with strengthening construction under basis；Concrete guard ring is suitable with above-mentioned fixing steel pile casting technique, digging process sinks by deadweight, if the wet soft deformation concrete guard ring of ground soil layer is just difficult to sink to continuing operation by locking, technique is heavy, bigger to soil around pile disturbance, easily seep water along gap and slip soil and draw body prop deformation tilt, more deeply, slightly weak earthen foundation reinforce in pore digging and be difficult to use, in reinforcing engineering, difficulty of construction is the biggest under the foundation.Therefore, seeking a kind of efficient, economical and practical, convenient to operate, the most secure support with manually dug piles method becomes urgent need and solves the technical problem that.
Therefore, it is necessary to provide a kind of extension type support with manually dug piles structure.
Utility model content
The purpose of this utility model is to provide a kind of extension type support with manually dug piles structure.
The technical solution of the utility model is as follows:
A kind of extension type support with manually dug piles structure, including steel plate, bolt, the first connecting portion being formed at described steel plate two opposite sides and the second connecting portion, described first connecting portion is formed with bolt hole, described second connecting portion is formed with chute, described first connecting portion and folded the setting of described second connecting portion make described steel plate enclose volume formation pipe, described bolt hole is corresponding with described runner position, described bolt inserts described bolt hole and described chute, makes described first connecting portion and the fixing connection of the second connecting portion.
Preferably, described steel plate is rectangular steel plates, and described first connecting portion and described second connecting portion lay respectively at the both sides in described steel plate length direction, and described chute is arranged along the length bearing of trend of described steel plate.
Preferably, described steel plate thickness is 2-3mm.
Preferably, also include that conduit, described conduit are located in described steel plate encloses the pipe that volume is formed and the length of described conduit is more than the width of described steel plate.
Preferably, the quantity of described conduit is two.
Preferably, described conduit is plastics airway.
Preferably, described first connecting portion and the second connecting portion lay respectively at outside and the inner side of described pipe.
Preferably, also include that nut, described nut are welded in described bolt hole.
The beneficial effects of the utility model are: this utility model utilizes extension type support with manually dug piles to construct, it is achieved that artificial stake continuous excavation supporting operation, lift and do not affected by prop aperture, top is little after casing is flexible, can directly under enter understratum；Prop up sheath thin, decrease earth volume excavated volume；Can overcome that earth excavation amount is big, formwork supporting plate casting concrete amount is big with excavation immediate support stress, personal security hidden danger is many, presetting period length is difficult to continuous excavation supporting in hole defect, decrease the disturbance to the supporting soil body, beneficially stake holes and ground safety；Dry sand ash is easy to fill gap and closely knit, can absorb hole wall moisture, soil property of hardening, again can waterproof raising intensity after solidification；The method is convenient to operate, and quick construction is efficient, and safe and reliable, comprehensive cost is cheap；It is difficult to be completely exhausted out additionally, due to the air when foundation bottom casting concrete, often forms the hidden danger such as space, by plug in conduit aerofluxus slip casting again, by irregular space or gap filling, reach to pour closely knit good consolidation effect.
