Abstract
The utility model relates to a double-row pile supporting structure with inclined struts, and belongs to the technical field of foundation pit projects and slope projects. The double-row pile supporting structure comprises a plurality of groups of front-row piles, a plurality of groups of back-row piles, top beams I, top beams II, connecting beams and the inclined struts, wherein the front-row piles and the back-row piles are arranged in a parallel mode. The top beams I are arranged at the tops of the front-row piles, the top beams II are arranged at the tops of the back-row piles, the connecting beams connected with the back-row piles are horizontally arranged at the tops of the front-row piles, and the inclined struts are arranged between the tops of the front-row piles and the tops of the back-row piles. According to the double-row pile supporting structure, the connecting beams at the tops of the front-row piles connect the front-row piles with the back-row piles, and lateral resisting stiffness can be intensified; and the front-row piles are connected with the back-row piles through the inclined struts, rigidity of a cantilever section of the double-row pile structure can be improved, displacement of the pile tops is reduced, meanwhile reliability of connection between the piles and the top beams can be improved, the front-row piles become compression-flexure members, and the flexural capacity of the front-row piles is improved.
Description
Technical field
The utility model relates to
OnePlant the Retaining Structure with Double-row Piles that is provided with diagonal brace, belong to base pit engineering and slope project technical field.
Background technology
In the city of an inch of land is an inch of gold, foundation ditch digs darker and darker, geological conditions worse and worse, surrounding is built or construction structure is intensive or near municipal highway, this has brought certain difficulty for design of supporting and protection structure, construction.At present, the normal supporting scheme that adopts of China has: put slope excavation, soil-nail wall support, pile-anchor retaining, campshed and add the support patterns such as inner supporting structure, double-row pile.Put slope excavation, soil-nail wall support, the pile-anchor retaining construction will inevitably exceed building line, but because the soil beyond building line is subject to countries and regions' policy restriction, perhaps need to use through relevant departments' licensor, brought great inconvenience for the smooth construction of building basement; Campshed adds that the inner supporting structure cost is high, long construction period and the basement structure construction scope of operation few; Though Retaining Structure with Double-row Piles in the past has the characteristics of good integrity, displacement is difficult to satisfy existing design specifications requirement.Therefore, the existing conventional supporting and protection structure of using has certain limitation.
Summary of the invention
The purpose of this utility model is to provide a kind of and controls soldier pile stake top displacement and can improve the Retaining Structure with Double-row Piles that the supporting and protection structure stress performance also can improve the reliability of node connection, in order to solve the problems of the prior art.
The technical solution of the utility model is: a kind of Retaining Structure with Double-row Piles that is provided with diagonal brace comprises front campshed 1 and rear campshed 2 that many groups are arranged in parallel, hat beam I 3, hat beam II 4, linking beam 5 and diagonal brace 6.Front campshed 1 top is provided with hat beam I 3, and rear campshed 2 tops are provided with hat beam II 4, and front campshed 1 top is horizontally disposed with the linking beam 5 that is connected with rear campshed 2,1 of front campshed push up and rear campshed 2 tops between be provided with diagonal brace 6.
Described rear campshed 2 cantilever segment length are 2.5m～4m.
The rectangular array arrangement of pile body layout and the each interval of described front campshed 1 and rear campshed 2 are arranged, and resist by the length that increases front campshed 1 the pile body sedimentation that the vertical force component that transmitted by diagonal brace 6 causes.
The spacing of described diagonal brace 6 is determined according to the displacement of the stake required control in top.
Use step of the present utility model is:
(1) according to the requirement of Geological condition and the computational analysis of foundation ditch safety and stability, determine diameter (sectional dimension), pile spacing and the array pitch of forward and backward campshed; Long, the pile body cross-sectional strength of stake and Reinforcement Design to forward and backward campshed; Determine the stake apical cap beam section size of forward and backward campshed and carry out arrangement of reinforcement and calculate; Determine sectional dimension, spacing and the quantity of reinforcement of linking beam; Determine the spacing of diagonal brace and sectional dimension etc.; Determine the excavation operation.
(2) campshed 2 after the construction; The stake type is determined by design.
(3) campshed 1 before the construction; The stake type is determined by design.
(4) space segmentation is excavated to position, 1 top of front campshed, keeps at a certain distance away to establish and does not excavate soil layer as the back-pressure layer, construction front and rear row dowel crown beam and linking beam 5 between the back-pressure layer, and construction diagonal brace 6.After reaching design strength, excavation back-pressure layer, front and rear row dowel crown beam and the coupling beam of construction back-pressure interval, and construction raker beam.
(5) layer and section is excavated to the end, hole.
The beneficial effects of the utility model are: Double-row-piles Structure can increase its anti-side rigidity by the forward and backward campshed of front campshed stake top linking beam connection; Connect by diagonal brace and push up in forward and backward campshed stake, can increase the stiffness reduction stake top displacement of double-row pile cantilever segment, can also improve the reliability that stake is connected with Guan Liang simultaneously, make front campshed become bending component, improved the curved bearing capacity that is subjected to of front campshed.
