Abstract
The utility model discloses a foundation pit steel pipe brace replacing and construction structure for a ramp. The foundation pit steel pipe brace replacing and construction structure comprises a foundation pit dug in the peripheral length direction of the ramp, wherein support piles are piled around the foundation pit; an inner support system is connected inside each support pile; a ramp bottom plate is laid and an inner ramp wall and an outer ramp wall on the two sides of the ramp bottom plate are built inside the foundation pit; a swinging rib is reserved at the top end of each of the inner and outer ramp walls; an edge beam is arranged inside the outer ramp wall along the length direction of the ramp; the inner and outer ramp walls are higher than the standard height of the bottom of the edge beam; a plurality of embedded steel plates are embedded in the edge beam in sequence and at intervals; a plurality of post-thickened embedded part steel plates corresponding to the embedded steel plates one by one are connected inside the inner ramp wall; a steel pipe brace is connected between each embedded steel plate and the post-thickened embedded part steel plate corresponding to the embedded steel plate; and backfilled earth is backfilled and plain concrete conversion plate strips are laid between the support piles and the outer ramp wall. Due to the adoption of the structure, the brace replacing system is stressed uniformly and stably and has enough strength.
Description
Technical field
The utility model relates to a kind of foundation ditch support replacement constructing structure, relates in particular to a kind of ramp foundation ditch steel pipe support support replacement constructing structure.
Background technology
In the Construction of Deep Foundation of highrise building, the foundation pit supporting project construction period is long, and cost is high, is the emphasis stage of whole engineering.The design form of pattern foundation pit supporting structure is more, but is subjected to the restriction of engineering present position and geological conditions, and not only economy but also applicable support form were often few.At present concrete inner support system requires low, easy construction to be applied in more and more in the engineering of deep foundation pit support because of it to surrounding enviroment, but is subjected to the restriction of foundation ditch support system, engineering construction during to certain position the dismounting of inner support be a necessary process.In the construction of basement car ramp, need to carry out special support replacement technology construction to the ramp, just can carry out the foundation ditch inner support and remove, guarantee ramp construction safety when then carrying out the construction of follow-up ramp.

1 application number is that the Chinese patent of CN201220017701.2 discloses " bracing of foundation pit fagging structure ", the utility model discloses bracing of foundation pit fagging structure, comprise the concrete slab body, be embedded in respectively the parallel horizontal two groups of reinforcing bars in upper and lower of concrete slab body, and described horizontal two groups of reinforcing bar one ends directly anchor into basement structure, the described horizontal two groups of reinforcing bars that are embedded in the upper and lower of concrete slab body intersected before anchoring into basement structure, and then directly anchored into basement structure.
2 application numbers are that the Chinese patent of CN201020676839.4 discloses that " hole steel sheet piling pit supporting construction in a kind of hole, hole steel sheet piling pit supporting construction in a kind of hole relate to and cheat steel sheet pile supporting and protection structure in a kind of hole, belong to the Geotechnical Engineering field.The utility model comprises hole end absolute altitude in absolute altitude at the bottom of parallel with the earth's surface respectively hollow place, hole, absolute altitude hole end absolute altitude in the hole vertically arranges steel sheet pile at the bottom of the hollow place, the upper end of steel sheet pile connects channel-section steel formation channel-section steel and encloses purlin, and channel-section steel encloses joint steel pipe or shaped steel formation inner support on purlin.
Although the 1st ~ 2 patent has a series of advantage, can not solve in the construction of basement car ramp, the series of problems such as ramp support replacement technology construction are removed thereby carry out the foundation ditch inner support, then carry out the construction of follow-up ramp and guarantee the ramp construction safety.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of have enough intensity, rigidity are provided, a kind of ramp foundation ditch steel pipe support support replacement constructing structure of sound construction, equalization stable power transmission.
a kind of ramp of the present utility model foundation ditch steel pipe support support replacement constructing structure, it is included in the foundation ditch that ramp periphery length direction digs, set soldier pile on described foundation ditch limit, be connected with interior support system in described soldier pile inboard, be equipped with ramp place's base plate and build in described foundation ditch ramp interior wall and the ramp exterior wall that is positioned at base plate both sides, place, ramp arranged, be reserved with on the top of ramp interior wall and ramp exterior wall and get rid of muscle, be provided with side bar in the ramp inner side of outer wall one along the ramp length direction, the height of described ramp interior wall and ramp exterior wall is higher than the absolute altitude at the bottom of the beam of side bar, the interval is embedded with the polylith pre-embedded steel slab successively on described side bar, interior wall inboard, ramp be connected with the polylith pre-embedded steel slab one by one corresponding arrange after increase the embedded part steel plate, increase after each piece pre-embedded steel slab and setting corresponding to it and be connected with the steel pipe support between embedded part steel plate, backfill has the first floor backfill between soldier pile and described ramp exterior wall, be equipped with plain concrete conversion strip at the top of described first floor backfill, be filled with the second layer backfill last time in described plain concrete conversion strip.
Adopt the beneficial effect of the utility model structure to be: in the construction of basement car ramp, the stressed complexity in place, ramp, need to carry out the construction of support replacement technology to the place, ramp, the foundation ditch inner support could be removed, guarantee ramp construction safety when then carrying out the construction of follow-up ramp.The steel pipe support is installed between the side bar on ramp interior wall and ramp inner side of outer wall, backfill first floor backfill between soldier pile and ramp exterior wall, then lay first floor plain concrete conversion strip at the top of first floor backfill, fill out the second layer backfill last time in first floor plain concrete conversion strip.Wholely like this consisted of take steel pipe support, side bar, backfill, plain concrete conversion strip as main stable support-replacing system.The suffered power of steel pipe support can equalization stable in addition passes to the ramp interior wall, the slab column of passing to agent structure that then can equalization stable.So adopt this structure to make the support-replacing system stress balance stablize, have enough intensity, rigidity, guarantee balanced power transmission and the rigidity stability and safety of the support replacement construction of basement car ramp.
