Description
Technical field
It the utility model is related to a kind of building barricade, more particularly to a kind of drawing anchor formula L-type Reinforced Concrete Retaining Walls.
Background technology
At present, the Cantilever Retaining Wall and counterfort wall poured using armored concrete is widely used in engineering construction and worked as
In.But according to《Technique Code for Building Slope Engineering》Regulation, existing Cantilever Retaining Wall supporting height are helped no more than 6m
Wall type barricade is no more than 10m.Therefore, Cantilever Retaining Wall there are following defect：Barricade supporting and retaining system limited height；Wall height is got over
High concrete dosage will increased dramatically, and economy is poorer；Barricade is deformed and stability is difficult to control.And counterfort wall is by adding
If floor, although improving the anti-side rigidity of retaining structure, maxi-mum height has also obtained certain raising, concrete amount
It is consequently increased, while concrete component formwork erection, the work on the spot amount such as to pour also bigger.Therefore, a new material is sought
Extremely it is necessary to substitute concrete component.
The content of the invention
The technical problems to be solved in the utility model, it is to provide a kind of drawing anchor formula L-type Reinforced Concrete Retaining Walls, by this
Barricade substitutes traditional counterfort, and to save the reinforcing bar of buttress portion and concrete, and the effective supporting and retaining system that can improve barricade is high
Degree.
What the utility model was realized in：One kind draws anchor formula L-type Reinforced Concrete Retaining Walls, including an armored concrete to stand
Plate, a reinforced concrete floor and several drawing anchor bar bodies；The armored concrete riser is built up in the reinforcing bar and mixed vertically
Coagulate on native bottom plate；Some anchor heads are provided with the armored concrete riser, are embedded with the reinforced concrete floor some
Individual anchor plate；It is locked on an anchor head per one end of the drawing anchor bar body, the other end is anchored in an anchor plate
On.
Further, a PVC protection pipes are arranged with per the outside of the drawing anchor bar body.
Further, the armored concrete riser and reinforced concrete floor be live formwork erection casting concrete one into
Type.
Further, it is described to draw anchor bar body to apply the axial tension component of prestressed stretch-draw locking.
Further, the angle drawn between anchor bar body and reinforced concrete floor is 45 °~75 °.
Further, the distance between adjacent two described drawing anchor bar bodies are 3~5m.
Further, the back of the armored concrete riser is arranged at per the anchor head.
The utility model has the following advantages that：1st, using drawing anchor bar body to substitute traditional counterfort, buttress portion is saved
Reinforcing bar and concrete；2nd, the stress of bottom plate and riser is simplified and clearly, by setting concealed beam and drawing anchor bar body soft
Property connection, for the stress of such bottom plate and riser closer to the situation of one-way slabs, this causes longitudinal reinforcement dosage to reduce；3rd, lead to
Tensioning grappling is crossed, can effectively control the lateral displacement of riser, improves effective supporting and retaining system height of barricade；4th, technique it is simple, into
It is ripe, and the duration of formwork erection and maintenance is greatly reduced.In a word, it is to cantilevered that the present invention, which draws anchor formula L-type Reinforced Concrete Retaining Walls,
The optimization and improvement of barricade and counterfort wall, it is not only simplified force modes, and saves substantial amounts of reinforcing bar
It is the type that a kind of side slope, the supporting and retaining system of barricade are all highly profitable and concrete, construction period have also obtained effective shortening,
Economic benefit and social benefit also highly significant.

It is anchored on an anchor plate 5.By by traditional counterfort be optimized for draw anchor bar body 3 after (or it may be said that the present invention draw
Anchor formula L-type Reinforced Concrete Retaining Walls 100 are the simplification versions of counterfort wall), the constraint type of armored concrete riser 1 also occurs
Change, i.e., be no longer the computation schema for being reduced to T-shaped beam, but levels off to the force modes of one-way slabs；Meanwhile anchor pole will be drawn
In in reinforced concrete floor 2, this make it that reinforced concrete floor 2 is no longer to be divided into each three-dimensional about for the end anchorage of body 3
The two-way slab of beam, but level off to the stress of one-way slabs under conditions of concealed beam is set.
The back of the armored concrete riser 1 is arranged at per the anchor head 4.The armored concrete riser 1 and steel
Reinforced concrete bottom plate 2 is that live formwork erection casting concrete is integrally formed, i.e. armored concrete riser 1 and reinforced concrete floor 2
It is reinforced concrete structure.In the specific implementation, needing first to be reserved with several on armored concrete riser 1 draws anchor anchor holes (not scheme
Show), draw anchor bar body 3 armored concrete riser 1 and the anchor head 4 at back can be passed through to lock to facilitate, anchor bar body 3 is drawn locking
Afterwards, it is necessary to will draw the closing of anchor anchor hole using concrete or cement grout, Pouring concrete at the same time pier closes anchor head 4；Certainly, exist
When being locked, it can also first pass through tensioning according to actual needs and apply prestressing force, then will draw anchor pole with anchor head 4 again
Body 3 locks.
A PVC protection pipes (not shown) are arranged with per the outside of the drawing anchor bar body 3, guarantor is played with Counter-pulled bolts body 3
The effect of shield.
It is described to draw anchor bar body 3 to apply the axial tension component of prestressed stretch-draw locking, in the specific implementation, the drawing anchor pole
Body 3 can be the axial tensional element such as high-strength deformed steel bar muscle or steel strand wires.
In order to improve stressed effect, in specific design, the folder drawn between anchor bar body 3 and reinforced concrete floor 2
Angle α is 45 °~75 °.The distance between the adjacent two drawing anchor bar body 3 d is 3~5m.
The utility model specific operation process is as follows：
(1) setting-out and positioning are carried out；(2) bed course is laid；(3) reinforcement placing concrete riser and reinforced concrete floor
Reinforcing bar；(4) formwork erection, now need to reserve some pvc pipes in the part of armored concrete riserIn order to draw anchor pole
Body can pass through；(5) one end for drawing anchor bar body is fixed on anchor plate and is positioned in reinforced concrete floor, pour coagulation
Soil；(6) age of the maintenance to design；(7) other end for drawing anchor bar body is locked on anchor head, and if it is screw-thread steel to draw anchor bar body
Muscle, then locked using supporting nut；If drawing anchor bar body is steel strand wires, the intensity of jack tension extremely design is first used, so
Locked again using intermediate plate afterwards；Simultaneously before anchor head is locked, the prestressing force of needs can also be applied according to actual needs；
(8) closing of anchor anchor hole will be drawn using concrete, Pouring concrete at the same time pier closes anchor head.
With reference to some specific embodiments, the utility model is described in further detail：
Specific embodiment one：
It refer to shown in Fig. 1 and Fig. 2, one kind draws anchor formula L-type Reinforced Concrete Retaining Walls 100, including an armored concrete to stand
Plate 1, a reinforced concrete floor 2 and several drawing anchor bar bodies 3；The armored concrete riser 1 is built up in the steel vertically
On reinforced concrete bottom plate 2；It is provided with some anchor heads 4 on the armored concrete riser 1, it is pre- on the reinforced concrete floor 2
