Description
Technical field
The utility model relates to a kind of double-row pile heel row anchors to draw foundation pit supporting construction, belong to Geotechnical Engineering field.
Background technique
Retaining Structure with Double-row Piles refers to is arranged two rows of parallel stakes in foundation soil, and front two rows stake pile body is in rectangle or plum blossom
Shape arrangement is arranged collar tie beam in two rows of stake tops, and is connected with connection beam, along crater wall parallel direction, forms door shape space structure, is
Space statically indeterminate structure, overall stiffness is big, can effectively limit foundation pit deformation, under external load effect complicated and changeable, energy
The internal force of adjust automatically supporting construction itself is allowed to adapt to complicated and often unpredicted loading condition.
Traditional double-row pile adds anchor pole (rope) structure stream line to be set to preceding campshed, and anchor cable and rear campshed are without contacting, the knot
The characteristics of campshed is equivalent to anchor, can not play double-row pile after in structure.
Summary of the invention
The utility model aim be to provide a kind of big rigidity of structure, cost economic, be suitable for excavation of foundation pit depth it is relatively deep or
The poor double-row pile heel row anchor of soil property draws foundation pit supporting construction.
The technical scheme adopted by the utility model is that: a kind of double-row pile heel row anchor drawing foundation pit supporting construction, including it is used for base
Preceding campshed, the rear campshed, anchor pole of supporting are cheated, is respectively equipped with front-seat dowel crown beam and rear campshed at the top of the preceding campshed and rear campshed
Crown beam, and between the stake of preceding campshed, rear campshed be equipped with stake between reinforced concrete plate and inter-pile soil, the top of the anchor pole around rear campshed extremely
Preceding campshed tensioning anchoring.
Further, the preceding campshed and rear campshed pass through reinforced concrete plate and stake between front-seat dowel crown beam, heel row dowel crown beam, stake
Between soil form space portal framed structure, anchor pole and the common stress of door frame, compatible deformation.
Further, the preceding campshed, rear campshed use bored concrete pile, Prefabricated Concrete stake, engineering method stake, steel sheet pile or combined pile
In it is any.
Further, the quantity of the anchor pole is arranged two or two or more.
The beneficial effects of the utility model are: compared with prior art, the invention draws anchorage using double-row pile heel row
Pit supporting construction, forward and backward campshed form space portal framed structure, forward and backward campshed by front and rear row dowel crown beam, concrete plate and inter-pile soil
Bored concrete pile, Prefabricated Concrete stake, engineering method stake, steel sheet pile or combined pile can be used；Anchor pole (rope) is tensioned around rear campshed to preceding campshed
Anchoring.The overturning stability of suspended wall supporting construction greatly improved around the way of rear campshed in anchor pole (rope), pile body resists anchor pole
The bearing capacity of (rope) drop-down component, top inter-pile soil are obtained pre-tightening by prestressing force more preferably to play the effect of stake soil globality,
Anchor pole (rope), the common stress of door frame, compatible deformation, the advantages of double-row pile and anchor pole (rope) can be given full play to, non-deformability
Relatively strong, construction technology is simple, quick, cost economic.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.
Detailed description of the invention
Fig. 1 is a kind of structural profile illustration of the utility model.
Fig. 2 is a kind of structural plan schematic diagram of the utility model.
In the figure, it is marked as campshed before 1-, campshed after 2-, 3- anchor pole (rope), the front row 4- dowel crown beam, 5- heel row dowel crown beam, 6-
Reinforced concrete plate between stake, 7- inter-pile soil.
Specific embodiment
The utility model is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1 to Figure 2, a kind of double-row pile heel row anchor draws foundation pit supporting construction, including the front row for pattern foundation pit supporting structure
Stake 1, rear campshed 2, anchor pole 3, it is characterised in that the top of the preceding campshed 1 and rear campshed 2 is respectively equipped with front-seat dowel crown beam 4 with after
Campshed crown beam 2, and reinforced concrete plate 6 and inter-pile soil 7 between stake are equipped between the stake of preceding campshed 1, rear campshed 2, the top of the anchor pole 3 around
Rear campshed 2 is tensioned to preceding campshed 1 and anchors.
In the present embodiment, the preceding campshed 1 and rear campshed 2 pass through reinforced concrete between front-seat dowel crown beam 4, heel row dowel crown beam 5, stake
Plate 6 and inter-pile soil 7 form space portal framed structure, anchor pole 3 and the common stress of door frame, compatible deformation.Preceding campshed 1, rear campshed 2 can
Using any in bored concrete pile, Prefabricated Concrete stake, engineering method stake, steel sheet pile or combined pile；The setting of anchor pole 3 two or two with
On.
The construction method of foundation pit supporting construction is drawn based on above-mentioned double-row pile heel row anchor, comprising the following steps:
Step 1: analyze according to site condition and calculating, determine that preceding campshed 1 and the specification of rear campshed 2, stake be long and array pitch,
It determines model, angle and the length of anchor pole (rope) 3, determines the specification of front row dowel crown beam 4, heel row dowel crown beam 5, determine front and back campshed
6 thickness of reinforced concrete plate and arrangement of reinforcement between stake；
Step 2: the preceding campshed 1 of construction and rear campshed 2, anchor pole (rope) 3 of constructing, construct front-seat dowel crown beam 4, heel row dowel crown beam 5
And reinforced concrete plate 6 between stake；
Step 3: reaching design to 6 intensity of reinforced concrete plate between anchor pole (rope) 3, front-seat dowel crown beam 4, heel row dowel crown beam 5 and stake
After it is required that, stretching anchor rod (rope) 3；
Step 4: excavation pit is to cheating bottom；
Step 5: being cleared up Foundation Pit bottom, being flattened, bed course is poured, construct bottom plate and main structure；
Step 6: backfilling fertile slot.
Forward and backward two campshed of this structure setting, forward and backward campshed can be used bored concrete pile, Prefabricated Concrete stake, engineering method stake, steel sheet pile or
Combined pile；Forward and backward campshed forms space portal framed structure by front and rear row dowel crown beam, concrete plate and inter-pile soil, anchor pole (rope) around
Rear campshed is tensioned to preceding campshed and anchors, and forms double-row pile heel row and draws anchorage pit supporting construction.Anchor pole (rope) is around rear campshed
Way greatly improved the overturning stability of suspended wall supporting construction, pile body resist anchor pole (rope) drop-down component bearing capacity, on
Portion's inter-pile soil obtains pre-tightening more preferably to play the effect of stake soil globality, anchor pole (rope), the common stress of door frame, coordination by prestressing force
The advantages of deforming, can giving full play to double-row pile and anchor pole (rope), non-deformability is stronger, and construction technology is simple, quick, cost
It is economical.
