Description
Technical field
The utility model relates to a kind of Contiuum type Retaining Structure with Double-row Piles, for building foundation pit supporting aspect, belongs to the realm of building construction.
Background technology
Expanding economy, has promoted the construction of urbanization process, and the building of inner city is more and more intensive, particularly emerging in multitude of high level, super highrise building, and the basement of building is towards darker, great development, and geological conditions is worse and worse.Use building line soil in addition because national policy limits again, or need after the agreement of relevant departments, could use, this makes troubles to smooth construction of building basement.At present, the normal supporting scheme adopting of China has: put slope excavation, soil-nail wall support, pile-anchor retaining, cement-soil gravity type retaining wall, campshed add the support pattern such as inner supporting structure, double-row pile, due to aforementioned requirement, put slope excavation, soil-nail wall support, pile-anchor retaining construction will inevitably exceed building line; Campshed adds that inner supporting structure cost is high, long construction period but the basement construction scope of operation is few; Retaining Structure with Double-row Piles in the past has the feature of its good integrity, anti-side rigidity is large, displacement is had to certain restriction, but stake top displacement and pile body displacement be also difficult to meet existing designing requirement, and the cantilever segment length of cantilevered Retaining Structure with Double-row Piles is very limited.Therefore, use conventional supporting and protection structure to have certain limitation.
Summary of the invention
In order better to address the above problem, the utility model proposes a kind of better Retaining Structure with Double-row Piles of controlling stake top and pile body displacement that has, the collaborative work ability of campshed simultaneously before and after can better bringing into play, and the anti-permeability performance of water-stop curtain is also improved.
The utility model Contiuum type Retaining Structure with Double-row Piles comprises the front campshed 1 and the rear campshed 2 that are arranged parallel to each other, the stake top of front campshed 1 and rear campshed 2 interconnects by coupling beam 4, between front campshed 1 and rear campshed 2, be provided with the water-stop curtain stake 3 of mutual interlock, and water-stop curtain stake 3 is positioned at coupling beam 4 belows, front campshed 1, rear campshed 2, water-stop curtain stake 3, coupling beam 4 interconnects back plane and arranges the array arrangement that is " V " font, front campshed 1 and rear campshed 2 are parallel to each other and each interval is alternately arranged, coupling beam below water-stop curtain stake and the front campshed 1 of interlock mutually, rear campshed 2 has formed Contiuum type Retaining Structure with Double-row Piles together, and layout is " V " font.
Water-stop curtain stake construction before front campshed and the construction of rear campshed, the water-stop curtain stake of still will constructing in the position of front campshed and rear campshed.
Water-stop curtain stake 3 described in the utility model is for deeply stirring stake or high-pressure rotary jet grouting pile.
Between front campshed 1 described in the utility model and rear campshed 2, the water-stop curtain stake 3 of setting is no less than a row, and 3 stakes long and front campshed 1 or rear campshed 2 of water-stop curtain stake are long isometric or not isometric.
Front campshed 1 described in the utility model and rear campshed 2 are reinforced concrete pile.
This Contiuum type Retaining Structure with Double-row Piles embodiment is as follows:
(1), according to the requirement of Geological condition and the computational analysis of foundation ditch safety and stability, determine pile spacing and the array pitch of forward and backward placing of reinforcement concrete pile; To long, the pile body cross-sectional strength of stake and the Reinforcement Design of forward and backward campshed; Determine sectional dimension and the quantity of reinforcement of coupling beam; Determine that diameter, spacing, the stake of water-stop curtain stake is long etc.; Determine excavation operation;
(2) construction water-stop curtain stake 3; Stake type by design and sealing requirement determine;
(3) campshed 2 after construction; Stake type is definite by designing;
(4) campshed 1 before construction; Stake type is definite by designing;
(5) in the work progress of (2), (3), (4) operation, require on front campshed, water-stop curtain stake and the centre of form line of three centres of form of rear campshed at front and back campshed, soil pressure after ensureing on campshed can effectively be delivered on front campshed, the anti-side rigidity of the better collaborative work of campshed and increase supporting and protection structure before and after making; Controlled greatly stake top and a pile body displacement, and its water-stop curtain stake can be with the stake appearance of forward and backward campshed etc. or not etc.;
(6) the construct stake top coupling beam of front campshed, rear campshed, makes whole support system form an entirety, the distortion of each several part cooperative bearing;
(7) soil excavation and transport.
The beneficial effects of the utility model are: two groups of soldier piles that are arranged parallel to each other (front campshed and rear campshed), and the stake top of front campshed and rear campshed is equipped with the coupling beam of contact each other; Between front campshed and rear campshed, be furnished with water-stop curtain stake along coupling beam direction, Double-row-piles Structure connects forward and backward campshed by stake top coupling beam can increase its anti-side rigidity; And Contiuum type Double-row-piles Structure is by the water-stop curtain stake being provided with, it forms a kind of all-in-one-piece and be similar to the supporting and protection structure of diaphragm wall together with forward and backward campshed, improve to a great extent its anti-side rigidity, can effectively control pile body and the stake top displacement of cantilevered double-row pile; Solve the coefficient problem of sharing of front and back campsheds, the collaborative work of campsheds before and after having ensured, before and after giving full play to, the service behaviour of campshed, effectively saves construction costs; Meanwhile, water-stop curtain stake, under the extruding of front and back campshed, can improve its anti-permeability performance greatly.
