Abstract
The invention relates to a foundation pit exposed corner hinged anchor beam supporting device and a use method of the foundation pit exposed corner hinged anchor beam supporting device, and belongs to the technical field of foundation pit supporting devices. The foundation pit exposed corner hinged anchor beam supporting device is designed so as to solve the problems that stress of a foundation pit exposed corner is concentrated, and a supporting structure is unstable. The foundation pit exposed corner hinged anchor beam supporting device is mainly formed by a plurality of sections of anchor rod beams in a mutually-hinged mode. Each section of the anchor rod beam is composed of a steel beam, a hinged joint and anchor rods. The steel beams are long cylinders. The cross sections of the steel beams are rectangular. Anchor rod holes are formed in each steel beam at intervals of a certain distance. Each hinged joint is composed of a hinged fork, a hinged column and a hinged pin. Circular holes mutually matched are formed in each hinged fork and each hinged column. The hinged forks and the hinged columns are connected through the hinged pins, and one hinged fork and one hinged column are fixed at two ends of each steel beam respectively. The anchor rods are installed on the anchor rod holes of the steel beams. The foundation pit exposed corner hinged anchor beam supporting device is simple in structure, low in cost, convenient to construct, short in project period, strong in project practicability and capable of effectively controlling stability of the foundation exposed corner.
Description
Technical field
The invention belongs to the pattern foundation pit supporting structure equipment technical field, be specifically related to a kind of foundation ditch external corner suspension device and using method thereof, relate in particular to the hinged anchor beam suspension device of foundation ditch external corner and using method thereof.
Background technology
Along with the development of base pit engineering, the flat shape of foundation ditch is more and more irregular, and the external corner of different situations occurs in a large number.The foundation ditch external corner belongs to the position that stress is concentrated because the sudden change of shape and the increase of free face cause the internal force of this place's soil body and supporting and protection structure very complicated.A large amount of engineering practices show, all greater than the foundation ditch middle part, the foundation ditch external corner is the unfavorable position of Deformation control, less stable for soil pressure in the foundation ditch external corner certain limit and horizontal movement, be easy to that excessive deformation takes place or integral body is collapsed, thereby the surrounding buildings deposits yields is had a strong impact on.
Collapsing that foundation ditch external corner position takes place has tangible continuous collapse feature, i.e. first local buckling, and part supporting and protection structure lost efficacy, and then destroyed and continued development, caused the part to be collapsed, and final external corner integral body is collapsed.
At present, the foundation ditch external corner adopts the support pattern identical with normal foundation pit side-wall mostly, and supporting effect is undesirable.If adopt strong supporting or the special supporting mode of adding at the foundation ditch external corner, make the supporting and protection structure of foundation ditch external corner have enough redundancies, when foundation ditch local buckling, the redundant Load Transfer at external corner place can be arrived other positions of foundation ditch, allow the excessive load in external corner place be born jointly by whole support system, foundation ditch just can occurrence of large-area unstability cave in, can not produce surrounding building yet and to have a strong impact on, therefore, need a kind of new foundation ditch external corner support technology measure of invention, with stablizing of effective control foundation ditch external corner.
Summary of the invention
The purpose of this invention is to provide the hinged anchor beam suspension device of a kind of foundation ditch external corner, this device not only can effectively solve the stability control difficult problem of foundation ditch external corner, and construction technology is simple, Technological Economy is feasible.
The present invention provides the using method of this device simultaneously.
The technical solution used in the present invention is: the hinged anchor beam suspension device of foundation ditch external corner, and it mainly is hinged by some sections anchor pole beams and forms, and every section anchor pole beam is formed by girder steel, articulated joint and anchor pole; Described girder steel is the long column body, and the cross section is rectangle, arranges a bolthole on the girder steel at a certain distance; Described articulated joint is made up of hinged fork, articulated column and swivel pin, and the circular hole of mutual coupling is arranged on hinged fork and the articulated column, interconnect by swivel pin, and hinged fork and articulated column is separately fixed at the two ends of girder steel; Described anchor pole is installed on the bolthole of girder steel.
Construction using method of the present invention is: at first according to the physical dimension of foundation ditch external corner, select the girder steel of different length, and carry out assembly unit by articulated joint, the hinged girder steel after the assembly unit is fitted tightly with near the sidewall of foundation ditch external corner; Beat armature boring, skyhook according to the position of bolthole on the girder steel at foundation ditch external corner sidewall then; Utilize anchor pole that hinged girder steel is fixed on the foundation pit side-wall at last, and anchor pole is applied a certain size prestressing force.
Operating principle of the present invention is: at the characteristics that foundation ditch external corner stress is concentrated, the foundation pit side-wall horizontal movement is big, generation integral body is easily collapsed, adopt girder steel and anchor pole that foundation ditch external corner sidewall is carried out powerful supporting, form anchor beam, simultaneously, utilize articulated joint that each anchor beam is coupled together, form a supporting integral body, so that the stress transfer of foundation ditch external corner arrives other position of foundation ditch, thereby guaranteed the stable of foundation ditch external corner.
The invention has the beneficial effects as follows: the hinged anchor beam suspension device of foundation ditch external corner is simple in structure, with low cost, easy construction, the duration is short, engineering practicability is strong, and can improve the stress distribution of foundation ditch external corner, effectively controls the stable of foundation ditch external corner.
