Background technology
Along with the quickening of expanding economy and urbanization process, the building of inner city is more and more intensive, and particularly high-rise, super highrise building is newly-built in a large number, and the basement of building is towards larger, Shenzhen Development Bank more.At present, the normal supporting scheme that adopts of China has: put slope excavation, soil-nail wall support, pile-anchor retaining, cement-soil gravity type retaining wall, campshed 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 the national policy restriction, perhaps needs the license through relevant departments, this has brought great inconvenience for 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; Retaining Structure with Double-row Piles in the past has the characteristics of its good integrity, but overturning or slip resistance analysis and distortion are difficult to satisfy existing design specifications requirement.Therefore, existing conventional supporting and protection structure has certain limitation.
Summary of the invention
The purpose of this utility model is to provide a kind of resistance to capsizing that improves can reduce the Retaining Structure with Double-row Piles of displacement again.
The technical solution of the utility model is: a kind of Double-row-piles Structure that is provided with the vertical anchor cable of prestressing force 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 the vertical anchor cable 6 of prestressing force.The top of front campshed 1 and rear campshed 2 is respectively equipped with hat beam I 3 and hat beam II 4, is connected by linking beam 5 between hat beam I 3 and hat beam II 4, the rear campshed 2 of each group between equidistant or unequal-interval be provided with the vertical anchor cable 6 of prestressing force.
The anchor head of the vertical anchor cable 6 of described prestressing force is fixed on the hat beam II 4 on rear campshed 2 tops, and the anchoring section 7 of the vertical anchor cable 6 of prestressing force is positioned at following soil layer at the bottom of 1 of front campshed.
The length of the anchoring section 7 of the vertical anchor cable 6 of described prestressing force is greater than 6m.
The rectangular array arrangement of pile body layout and the each interval of described front campshed 1 and rear campshed 2 are arranged.
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 (cross-sectional sizes), pile spacing and the array pitch of forward and backward campshed; Determine anchoring section, freedom length and the anchor cable spacing of the vertical anchor cable of prestressing force; 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 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) the vertical anchor cable of construction prestressing force.
(5) stake apical cap beam and the linking beam of the forward and backward campshed of construction make whole support system form an integral body, each several part cooperative bearing, distortion.
(6) anchor cable is applied prestressing force; After adding prestress anchorage cable between the stake of rear campshed, can effectively improve the resistance to capsizing of supporting and protection structure, reduce the displacement of supporting and protection structure.
(7) soil excavation and transportation.
The beneficial effects of the utility model are: add the vertical anchor cable of prestressing force between the stake of rear campshed after, can effectively improve the resistance to capsizing of supporting and protection structure, reduce the displacement of supporting and protection structure, also can reduce simultaneously the length of rear campshed with saving construction cost.
