Abstract
The utility model relates to a stable control structure of a foundation ditch bracing precast pile in the field of foundation ditch bracing engineering. The stable control structure is characterized in that the mutual connection in the circumference direction of a foundation ditch in the plane is realized, a wing edge and a web plate of the foundation ditch bracing precast pile (1) are wrapped in a direction vertical to the circumference direction of the foundation ditch, and an integral structure is formed. The stable control structure (3) provided by the utility model has the advantages that the stability inside and outside the plane can be maintained by the precast pile (1), safety and reliability are realized, the construction is convenient, and the manufacture cost is low.
Description
Technical field
The present invention relates to the geotechnical engineering field, particularly relate to bracing of foundation pit engineering field.
Background technology
The bracing of foundation pit engineering is one of important component part of geotechnical engineering; Fender post (wall) form commonly used at present mainly contains cement earth pile, diaphragm wall, steel sheet pile, the SMW worker's method stake four big classes that bored pile adds water proof; What form for cast in situs is main stake (wall) body with steel concrete to wherein preceding two types; Consumptive material, big energy-consuming, cost is higher, produces potential safety hazard because of the site operation quality Control easily.Steel sheet pile and the stake of SMW worker's method are generally extracted steel wherein after construction is accomplished, the main material of fender post (wall) can be recycled, and therefore consumptive material, power consumption are less relatively; Fender post (wall) form that belongs to the less expensive environmental protection, but the lap position between the steel sheet pile can't satisfy strict water proof requirement, when foundation ditch digs deeply deeply; Steel sheet pile often leaks seriously, and steel sheet pile rigidity is lower in addition, applies thereby limit it; The stake of SMW worker's method needs local retaining soil of construction cement earth pile and water proof between primary structure member (being H shaped steel) in order to solve the native water proof problem of retaining, but when foundation ditch is dark; The stressed cracking of cement earth pile possibly cause water proof to lose efficacy; Cement-soil is not recyclable in addition, and certain material consumption is arranged, so cost is still higher.Bracing of foundation pit is one type of provisional engineering; Behind pit backfill, promptly accomplish all use value of engineering, therefore adopt callable prefabricated units (the H shaped steel good) like the bending resistance shear behavior but go along with sb. to guard him material-saving, energy-conservation, reduce construction costs significantly; And construction quality is easy to control; Possess vast potential for future development, but the water proof problem of prefabricated units junction is the bottleneck of its development of restriction, also is a blank in the domestic and international geotechnical engineering field; The previous proposition of the inventor is the WSP stake of water proof effectively; Solved the water proof problem of contiguous prefabricated stake junction, for preformed pile as bracing of foundation pit stake lay a good foundation, but not mentioned for the stable control problem of bracing of foundation pit preformed pile.
Summary of the invention
The object of the present invention is to provide a kind of stable control structure of bracing of foundation pit preformed pile, the stable control structure of this bracing of foundation pit preformed pile can effectively be controlled preformed pile stability in use, reliable in quality, and cost is low.
The stable control structure of this bracing of foundation pit preformed pile is being wrapped up the web of bracing of foundation pit preformed pile and the overall structure on an edge of a wing in horizontal plane, to interconnect along the foundation ditch circumferential direction perpendicular to the foundation ditch circumferential direction.
The stable control structure of bracing of foundation pit preformed pile of the present invention can make preformed pile keep in the plane and out-of-plane stability, and safe and reliable, easy construction, cost are low.
Description of drawings
Fig. 1 is the stable control structure layout sketch map of the used bracing of foundation pit preformed pile of one embodiment of the present of invention.
Fig. 2 is the stable control structure generalized section of the used bracing of foundation pit preformed pile of one embodiment of the present of invention.
The specific embodiment
As of the present invention like a Fig. 1 and an embodiment shown in Figure 2, the structure and the stable control principle of the stable control structure of the bracing of foundation pit preformed pile that main purpose is to introduce.Like Fig. 1 and shown in Figure 2; Foundation pit enclosure structure in the present embodiment comprises preformed pile (1) and support system (2) two parts composition, and preformed pile (1) is the combination of steel sheet pile and H shaped steel, when preformed pile (1) is constructed; Make the web of H shaped steel be positioned at excavation of foundation pit one side, opposite side is the soil body (4).In the present embodiment; Support system (2) is the steel concrete support system; When building the peripheral collar tie beam of support system (2), make web and a side wing edge of a part of concrete parcel H shaped steel, i.e. formation is like the stable control structure (3) of Fig. 1 and bracing of foundation pit preformed pile shown in Figure 2; Like this; H shaped steel when stressed because web receives the constraint of the stable control structure (3) of the bracing of foundation pit preformed pile that horizontal direction builds, and the stability of H shaped steel is improved significantly, preformed pile (1) malicious event that can avoid upset or distortion because of H shaped steel to cause.The characteristics of the stable control structure (3) of bracing of foundation pit preformed pile are in horizontal plane, to interconnect along the foundation ditch circumferential direction, are wrapping up the web of bracing of foundation pit preformed pile (1) and the overall structure on an edge of a wing perpendicular to the foundation ditch circumferential direction.
This patent includes but not limited to other job practicess of the alternative use of professional person in this area.
Claims (1)
1. the stable control structure of a bracing of foundation pit preformed pile is characterized by in horizontal plane and interconnects along the foundation ditch circumferential direction, perpendicular to the web of foundation ditch circumferential direction parcel bracing of foundation pit preformed pile (1) and the overall structure on an edge of a wing.
