Abstract
The utility model discloses a basement supporting construction of no concrete to propping, 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, 1.5~2.5m of the degree of depth of cutting the earth places the position billet on the engineering stake, engineering stake below the billet has 2~4, the basement is reinforced district's width by the livestock farm and for propping up 1m scope within the fender pile outward flange tangent line, is reinforced district's degree of depth and be the following 1.5m~2m of basement, set up steel shotcrete for the first time between first steel waist rail and the billet.
Description
Technical field
The utility model relates to a kind of basement supporting and protection structure, particularly a kind of without the basement supporting and protection 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 supporting and protection structure of concrete to support, solves the problem of prior art.
In the utility model, basement supporting and protection 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, first steel waist rail top mark is high identical with soldier pile top mark height, the embedded bar of first steel waist rail and soldier pile is welded to connect, prestressed cable anchorage is at first steel waist rail, digging depth 1.5 ~ 2.5m places billet in position on engineering pile, and the engineering pile below billet has 2 ~ 4.Billet thickness is 10 ~ 12cm, billet setting position is from basement edge 13 ~ 15m, fluted in the middle of billet, the recessed poor degree of depth is 8 ~ 12mm, length and width are 10 ~ 15cm, stabilization zone, basement passive area width is 1m scope within soldier pile outward flange tangent line, and the stabilization zone degree of depth is below basement substrate 1.5m ~ 2m.First time bracing members is set between first steel waist rail and billet.
The utility model construction speed is fast, and construction costs is low.
Accompanying drawing explanation
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, first bracing members, 7, billet, 8, engineering pile.
Detailed description of the invention
In embodiment, basement supporting and protection 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, first steel waist rail 2 top mark is high identical with soldier pile 1 top mark height, first steel waist rail 2 is welded to connect with the embedded bar of soldier pile 1, prestress anchorage cable 3 is anchored at first steel waist rail 2, billet 7 is placed in digging depth 1.5 ~ 2.5m position on engineering pile 8, and the engineering pile 8 below billet 7 has 2 ~ 4.Billet 7 thickness is 10 ~ 12cm, billet 7 setting position is from basement edge 13 ~ 15m, fluted in the middle of billet 7, the recessed poor degree of depth is 8 ~ 12mm, length and width are 10 ~ 15cm, stabilization zone, basement passive area 5 width is 1m scope within soldier pile 1 outward flange tangent line, and the stabilization zone degree of depth is below basement substrate 1.5m ~ 2m.First time bracing members 6 is set between first steel waist rail 2 and billet 7.
