Abstract

The invention provides a combined foundation pit supporting structure with an inclined strut and a pull anchor. An enclosure wall is arranged in the foundation pit supporting structure. The inclined strut is arranged at the top of the enclosure wall. The lower end of the inclined strut is connected with a support. The support is located at the bottom of a foundation pit and provided with a stiffening pile used for offsetting acting force of the inclined strut. The foundation pit is little in deformation and safe and reliable in structure. Materials are saved, the manufacturing price is lowered, the project period is short, and construction space is large.

Description

A kind of with diagonal brace and the combined type foundation pit supporting construction that draws anchor
Technical field
The present invention relates to technical field of civil engineering, particularly a kind of with diagonal brace and the combined type foundation pit supporting construction that draws anchor.
Background technology
Soft Deep Foundation Pit engineering in general adopts the supporting type of horizontal inner support, but for large-scale excavation engineering, huge support system is set, high, the densely covered inner support of engineering cost impact construction, and the involving great expense of inner support, support post and stand column pile three.Therefore, need to design a kind of simple, feasible support form, meet the requirement of economy, safety, convenient construction.
In pattern foundation pit supporting structure, tiltedly throwing support is the normal support form simple in structure adopting, but conventional oblique throwing support, need be after bottom slab concreting, and one end is supported on base plate, long in time limit, cost is high, and has the problem to foundation ditch internal modification.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the problem existing in existing pattern foundation pit supporting structure, provides a kind of with diagonal brace and the combined type foundation pit supporting construction that draws anchor.
In order to address the above problem, technical scheme of the present invention is such:
A kind of with diagonal brace and the combined type foundation pit supporting construction that draws anchor, in foundation pit supporting construction, be provided with enclosure wall and tiltedly throw support, tiltedly throw support upper end and connect enclosure wall top, tiltedly throw support lower end and connect the oblique support bearing of throwing, tiltedly throw support bearing and be positioned at foundation ditch bottom, described oblique throwing support bearing below is provided with bearing stake, tiltedly throws support bearing and is also connected with the stiffening pile that divides active force for offsetting oblique throwing support part.
Described enclosure wall top is provided with capping beam and is connected with oblique throwing support upper end.
Described bearing stake is concrete pile or the piling bar that stretches into foundation ditch bottom.
At least two of described bearing stakes.
In described stiffening pile, be provided with resistance to plucking muscle body, described resistance to plucking muscle body is locked on oblique throwing support bearing.
Described oblique throwing support is a H shaped steel or many H shaped steel combinations.
Described oblique throwing support is a steel pipe or many steel pipe combinations.
Beneficial effect, of the present invention a kind of with diagonal brace with draw the combined type foundation pit supporting construction of anchor, do not need by the time to establish support after bottom slab concreting and apply prestressing force, adopt independently bearing, foundation ditch safety is improved, distortion reduces, structural safety is stable.And saving material, saves cost, the duration is short, construction space is large.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, describe the present invention in detail;
Fig. 1 is of the present invention a kind of with diagonal brace and the cross-sectional view of drawing the combined type foundation pit supporting construction of anchor.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1, a kind of with diagonal brace and the combined type foundation pit supporting construction that draws anchor, in foundation pit supporting construction, be provided with enclosure wall 1, enclosure wall 1 comprises water-stop curtain and soil blocking pile, at enclosure wall 1 top, capping beam 2 is set, capping beam 2 is reinforced concrete structure or steel work, and capping beam 2 is connected with the upper end of tiltedly throwing support 3, and the pre-embedded steel slab of capping beam 2 or girder steel are connected with oblique throwing support 3.The lower end of tiltedly throwing support 3 connects one and tiltedly throws support bearing 4, tiltedly throws support bearing 4 and is positioned at foundation ditch bottom, and tiltedly throwing support bearing 4 is concrete structure or steel work, tiltedly throws support bearing 4 and is connected with for offsetting the stiffening pile 5 of oblique throwing support active force.
In order offsetting preferably, tiltedly to throw support active force, tiltedly to throw the near point A that support 3 is connected to oblique throwing support bearing 4, stiffening pile 5 connects its far point B through tiltedly throwing support bearing 4.
Below described oblique throwing support bearing 4, be provided with bearing stake 6, described bearing stake 6 is for stretching into reinforced concrete pile or the piling bar bottom foundation ditch.6 at least two of described bearing stakes.
In described stiffening pile 5, be provided with resistance to plucking muscle body 51, described resistance to plucking muscle body 51 is locked on oblique throwing support bearing 4 far point B.
Described oblique throwing support is a H shaped steel or many H shaped steel combinations, can decide according to the size of bearing capacity the quantity of H shaped steel.
Again or described oblique throwing support be a steel pipe or many steel pipes combinations, can decide according to the size of bearing capacity the quantity of steel pipe.
Of the present invention a kind of with diagonal brace with draw the combined type foundation pit supporting construction of anchor, diagonal brace bearing independently arranges, and is furnished with for offsetting the stiffening pile of diagonal bracing effect power, makes foundation ditch safe, is out of shape littlely, structural safety is stablized.Save material, save cost, the duration is short, construction space is large.
More than show and described basic principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not subject to the restriction of above-mentioned example; that in above-mentioned example and manual, describes just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
