Abstract
The utility model discloses a structure is strutted to basement that props to no concrete, a characterized by fender pile adopts the drilling bored concrete pile, set up the stagnant water curtain from the fender pile central point outside a 1.5~2m in orientation department, the stagnant water curtain adopts triaxial cement stirring stake, it sets up first steel waist rail to prop up the inboard orientation upper portion of fender pile, first steel waist rail top mark is high with to strut the pile bolck elevation the same, first steel waist rail is connected with the pre -buried welded steel who props up the fender pile, the anchor of prestressed anchorage cable is at first steel waist rail, the inboard orientation middle part of fender pile sets up the second and says the steel waist rail, and the second says that the anchor of prestressed anchorage cable says the steel waist rail at the second, and engineering pile bolck elevation is the same with basement bottom plate basement elevation, and the engineering stake is above -mentioned to set up the billet, sets up the steel shotcrete between billet and first steel waist rail, sets up the steel shotcrete between billet and the second way steel waist rail.
Description
Technical field
The utility model relates to a kind of basement support structure, particularly a kind of without the basement support structure of concrete to support.
Background technology
Tradition basement support technology is that basement supporting is provided with concrete and maintains basement supporting to support and stablize, but concrete can increase basement support cost greatly to support, also causes very large impact to earthwork outward transport in addition, thus delays the construction period.If by the safe and orderly adjustment of stress in basement Bracing Process, transfer and reallocation, make basement supporting when significant economic benefit and duration benefit obviously can be obtained without when inner support.But how to avoid in basement supporting construction process without concrete to support situation under safety problem be the problem that engineering staff faces.
Utility model content
The utility model is to provide a kind of without the basement support structure of concrete to support, solves the problem of prior art.
In the utility model, basement support structure adopts as follows: soldier pile adopts bored pile, and bored pile diameter is 600 ~ 900mm.Arrange water-stop curtain from soldier pile central point lateral direction 1.5 ~ 2m place, water-stop curtain adopts three axle cement mixing piles, and three axle cement mixing pile stake footpaths are 600mm or 500mm, and adjacent three axle cement mixing piles are engaged mutually, and occlusion distance is 200mm or 150mm.Inside soldier pile, top, direction arranges first steel waist rail, and first steel waist rail top mark is high identical with soldier pile top mark height, and the embedded bar of first steel waist rail and soldier pile is welded to connect, and prestressed cable anchorage is at first steel waist rail.
Second steel waist rail is set in the middle part of direction inside soldier pile, second steel waist bottom elevation is the first time soil excavation degree of depth, the embedded bar of second steel waist rail and soldier pile is welded to connect, second prestressed cable anchorage is at second steel waist rail, engineering pile cuts when second time soil excavation, engineering pile top mark is high identical with basement bottom board substrate absolute altitude, above engineering pile, billet is set, between billet and first steel waist rail, bracing members is set, between billet and second steel waist rail, bracing members is set.The stabilization zone width of basement passive area is 1m scope within soldier pile outward flange tangent line, and the stabilization zone degree of depth is below basement substrate 1.5m ~ 2m.
The utility model construction speed is fast, and construction costs is low.

Fig. 1 is basement supporting schematic diagram.
In each accompanying drawing: 1, soldier pile, 2, first steel waist rail, 3, prestress anchorage cable, 4, water-stop curtain, 5, basement passive area, 6, bracing members, 7, billet, 8, engineering pile, 9, second steel waist rail.
Detailed description of the invention
In embodiment, basement support structure adopts as follows: soldier pile 1 adopts bored pile, and bored pile diameter is 800mm.Arrange water-stop curtain 4 from soldier pile 1 central point lateral direction 1.8m place, water-stop curtain 4 adopts three axle cement mixing piles, and three axle cement mixing pile stake footpaths are 600mm, and adjacent three axle cement mixing piles are engaged mutually, and occlusion distance is 200mm.Inside soldier pile 1, top, direction arranges first steel waist rail 2, and first steel waist rail 2 top mark is high identical with soldier pile 1 top mark height, and first steel waist rail 2 is welded to connect with the embedded bar of soldier pile 1, and prestress anchorage cable 3 is anchored at first steel waist rail 2.
Inside soldier pile 1, second steel waist rail 9 is set in the middle part of direction, second steel waist rail 9 end absolute altitude is the first time soil excavation degree of depth, second steel waist rail 9 is welded to connect with the embedded bar of soldier pile 1, second prestress anchorage cable 3 is anchored at second steel waist rail 9, engineering pile 8 cuts when second time soil excavation, engineering pile 8 top mark is high identical with basement bottom board substrate absolute altitude, engineering pile 8 arranges billet 7 above, between billet 7 and first steel waist rail 2, bracing members 6 is set, between billet 7 and second steel waist rail 9, bracing members 6 is set.The stabilization zone width of basement passive area 5 is 1m scope within soldier pile outward flange tangent line, and the stabilization zone degree of depth is below basement substrate 1.5m ~ 2m.
