Abstract
The invention discloses a deformed bar concrete and cemented soil distributed type foundation pit supporting wall. The deformed bar concrete and cemented soil distributed type foundation pit supporting wall is characterized by being composed of a dual-shaft or three-shaft cement mixing pile machine or a cemented soil water sealing exterior wall constructed by TRD equipment and a cast-in-place deformed bar concrete soil stopping interior wall; the cast-in-place deformed bar concrete soil stopping interior wall is composed of cast-in-place tube-sinking bored piles with the H-shaped or T-shaped or rectangular cross section in parallel, and the distance between the interior wall and the exterior wall is 0.1-1 m. Compared with the prior art, the deformed bar concrete and cemented soil distributed type foundation pit supporting wall has the following obvious advantages that the consumed steel consumption is lowered by 20-30%, the manufacturing cost is lowered by 20-30%, and no mud contamination is formed. Compared with the prior art, a worker does not need to remove cemented soil on a steel mold, and the labor intensity of the worker and the construction cost are lowered.
Description
Technical field
The present invention relates to building foundation pit supporting engineering field, particularly relate to a kind of deformed bar concrete and cement-soil march-past pattern foundation pit supporting structure wall.
Background technology
As everyone knows, the bending resistance square of foundation pit supporting pile is the same with the beam stress principle on building top, and square-section is better than circular cross-section cost performance, but does not see columned beam in the world, is but cylindric soldier pile everywhere.Find afterwards in invention " the cast-in-place deformed bar concrete pile core cement-soil diaphragm wall of pattern foundation pit supporting structure " (ZL201120056477.3), " in twin shaft or triaxial cement diaphragm wall; be provided with cast-in-place deformed bar concrete pile core by spacing 0.8-3m; cement-earth underground continuous wall is that the cement mixing pile of diameter 0.5-1.5m intersects side by side composition, reinforced concrete pile core cross section is I shape or T font or Back Word type or rectangle or oblate type " of this claim.Larger problem is there is in construction, mainly after cement mixing pile driving construction, shake the punching block of heavy profile iron reinforced concrete pile core immediately in the cement-soil of non-initial set, filling with concrete, extricate oneself from a predicament and brace oneself up to action punching block time find that a large amount of soil cement from becoming stuck is on steel form, often pull out once, workman must shovel it with spades, thus, significantly increases labor strength, and pay great number reward, improve construction costs.
Summary of the invention
The object of the present invention is to provide deformed bar concrete and cement-soil march-past pattern foundation pit supporting structure wall, than the cylindric bored pile scheme of current designs, the rolled steel dosage of use reduces 20-30%, and cost reduces 20-25%, mud-less pollution.Compared with former invention, root out the cement-soil on punching block without the need to workman, reduce labor strength and construction cost.
The object of the invention is to be achieved through the following technical solutions: a kind of deformed bar concrete and cement-soil march-past pattern foundation pit supporting structure wall, it is characterized in that, pattern foundation pit supporting structure wall is by the cement-soil water-stopping external wall of twin shaft or three axle cement mixing pile machines or TRD equipment construction, form with the concrete gear of cast-in-place deformed bar native interior wall apportion, deformed bar concrete inner wall is I-shaped or T-shaped by cross section or the cast-in-place tube-sinking cast-in-situ pile of rectangle forms side by side, inner-outer wall spacing 0.1-1m.
The present invention compared with prior art, has following remarkable advantage: the rolled steel dosage of use reduces 20-30%, and cost reduces 20-25%, mud-less pollution.Compared with former invention, root out the cement-soil on punching block without the need to workman, reduce labor strength and construction cost.
Accompanying drawing explanation
Fig. 1 is an exemplary embodiments generalized section of the present invention.
Fig. 2 is gear soil interior wall and the water-stopping external wall cross sectional representation of an exemplary embodiments of the present invention.
In figure: 1 miscellaneous fill layer, 2 muds, the cement-soil exterior wall in 3 miscellaneous fills, 4 concrete Guan Liang, the cement-soil exterior wall of 5 muds, 6.T shape steel concrete interior wall, 7 foundation ditches, absolute altitude at the bottom of 8 foundation ditches, 9 main muscle, 10 stirrups.
Detailed description of the invention
An exemplary embodiments of the present invention as shown in Figure 1, Figure 2, before building foundation pit excavation, it is rectangle punching block that vibrator sunk pile machine shakes into cross section in miscellaneous fill (1) and mud (2), and two protrusion blooms are established in punching block end, is of a size of T-shaped stake two corner.Punching block shakes and is sink to design elevation, puts into reinforcing cage in punching block, Reperfu-sion concrete, then extricate oneself from a predicament and brace oneself up to action punching block, what punching block end was established two protrudes blooms and in soil, forms cavity when upper pulling out, and concrete filling cavity forms T-shaped stake, namely complete a T-shaped pile driving construction, go round and begin again, complete all T-shaped pile driving constructions.On foundation ditch building site, press design drawing position construction cement-soil water-stopping external wall (3,5) by triaxial cement mixing pile machine again, namely complete the making construction of pattern foundation pit supporting structure wall of the present invention, then by prior art earth excavation.
Claims (1)
1. a deformed bar concrete and cement-soil march-past pattern foundation pit supporting structure wall, it is characterized in that, pattern foundation pit supporting structure wall is by the cement-soil water-stopping external wall of twin shaft or three axle cement mixing pile machines or TRD equipment construction, form with the concrete gear of cast-in-place deformed bar native interior wall apportion, deformed bar concrete inner wall is I-shaped or T-shaped by cross section or the cast-in-place tube-sinking cast-in-situ pile of rectangle forms side by side, inner-outer wall spacing 0.1-1m.
