Abstract
The utility model provides a novel HSW working pile method foundation pit timbering structure, and relates to the technical field of geotechnical engineering in civil engineering, in particular to the technical field of a construction technology which combines H-shaped steel and steel sheet pile composite piles. The novel HSW working pile method foundation pit timbering structure comprises a broken stone cushion layer for reinforcing the earth surface and a steel sheet pile, wherein the steel sheet pile is arranged perpendicular to the broken stone cushion layer and penetrates through the broken stone cushion layer. The H-shaped steel which is perpendicular to the broken stone cushion layer is arranged on one side of the steel sheet pile, and H-shaped steel guide beams and H-shaped steel guide piles are sequentially arranged on the side, away from the steel sheet pile, of the H-shaped steel, wherein the H-shaped steel guide beams are used for controlling locating accuracy of the H-shaped steel, and the H-shaped steel guide piles are used for limiting the movement of the H-shaped steel guide beams. The novel HSW working pile method foundation pit timbering structure achieves the purposes of being large in structural rigidity, capable of protecting environment and being used cyclically, short in construction period, and low in manufacturing cost.
Description
Technical field
The utility model relates to the technical field of geotechnical engineering in the civil engineering, relates in particular to the technical field of the construction technology that H shaped steel is combined with the steel sheet pile compound pile.
Background technology
Steel sheet pile has quick construction, and steel sheet pile can be pulled out after foundation pit construction finished, and is recycling, the characteristics such as better economy.But because the anti-side direction degree of steel sheet pile less is out of shape larger.Having relatively high expectations and dig in surrounding enviroment should be less in the dark larger base pit engineering.
H shaped steel is that a kind of section area distribution ratio is optimized, the rational economic section high efficiency section bar of the ratio of strength to weight.Owing to all arrange with the right angle in each position of H shaped steel, so H shaped steel all has on all directions, and bending resistance is strong, construction is simple, save the advantages such as cost and lightweight construction, is mainly used in the stake of SMW engineering method in the base pit engineering at present.H shaped steel itself does not have snap close, is used for base pit engineering and only can keeps off soil, can not sealing.
For steel sheet pile and H shaped steel characteristics, Southeast China University has applied for that on April 9th, 2012 patent No. is 201220144932.X, and the utility model name is called: the patent application of " a kind of steel sheet pile and H shaped steel combination foundation pit supporting construction ".This engineering method has merged the advantage of sheet pile and H shaped steel, and has overcome self-defect, for the application of steel work in the deep big foundation pit engineering provides solution.
Summary of the invention
The utility model purpose provides that a kind of rigidity of structure is large, environmental protection, reusable edible, the duration is short, cost is low novel HSW worker's stake method foundation pit supporting construction and job practices thereof.
A kind of novel HSW worker's stake method foundation pit supporting construction (H shaped steel and steel sheet pile combined foundation ditch support structure, H Piles and Steel Sheet Piles Wall, be called for short HSW engineering method pile pit supporting construction), comprise for the hardcore bed of reinforcing the earth's surface, pass the steel sheet pile of hardcore bed perpendicular to the hardcore bed setting, one side of steel sheet pile is arranged the H shaped steel perpendicular to hardcore bed, arranges successively for the H shaped steel nose girder of controlling H shaped steel positioning accuracy, is used for the H shaped steel guide pile that restriction H shaped steel nose girder moves away from a side of steel sheet pile on the H shaped steel.
Job practices based on novel HSW worker's stake method foundation pit supporting construction of the present utility model comprises the steps:
The first step: comprehensive base pit engineering scale, surrounding enviroment condition, hydrogeological conditions, computational analysis determine that the model of steel sheet pile, H shaped steel, stake are long, lengthwise position, pile spacing;
Second step: lay hardcore bed on the surface, earth's surface, according to the design axis, get two of surperficial parallel installations with hardcore bed and be used for the steel sheet pile guide pile that restriction steel sheet pile nose girder moves vertical, two steel sheet pile guide piles are installed two steel sheet pile nose girders that are used for controlling the steel sheet pile positioning accuracy;
The 3rd step: adopt crawler crane between two steel sheet pile nose girders, to be pressed into steel sheet pile in conjunction with modes such as hydraulic vibration driver, static-pressure pile planting machines;
The 4th step: remove steel sheet pile guide pile, steel sheet pile nose girder, in a side of steel sheet pile H shaped steel guide pile, H shaped steel nose girder are installed;
The 5th step: adopt crawler crane between steel sheet pile and H shaped steel nose girder, to be pressed into H shaped steel in conjunction with the hydraulic vibration driver mode;
The 6th step: press the construction of design of foundation pit operating mode;
The 7th step: backfill, extract steel sheet pile, H shaped steel.
The utility model adopts technique scheme, compared with prior art have following advantage: the utility model adopts the structure of steel sheet pile and H shaped steel combination, kept not only that the bending resistance that H shaped steel itself has is strong, construction is simple, save the advantages such as cost and lightweight construction, simultaneously also overcome H shaped steel and itself do not had snap close, be used for base pit engineering and only can keep off soil, problem that can not sealing, thus the utility model is on form of structure and job practices has obtained that the rigidity of structure is large, environmental protection, reusable edible, the duration is short, cost is low advantage.
