Description
Technical field
The present invention relates to the construction bearing safety problem of construction, pile foundation engineering technique, more particularly to bored concrete pile, specifically
Say it is a kind of soft soil foundation bored concrete pile horizontal bearing reinforcement and its construction method.
Background technology
With the exploitation of the extensive land resource of China, pile foundation turns into the main supporting body of all kinds of engineering constructions, it
It is widely used in the fields such as skyscraper, highway bridge, wind power foundation.Pile foundation is in addition to vertical load is born, in many situations
Under (for example, earthquake load, wind load, neighbouring preloading, it is neighbouring excavate, bank protection is reinforced etc.) still suffer from certain horizontal loading.
Cast-in-situ bored pile is used widely with its easy construction, high capacity.In recent years, the quickening of urbanization process and environment control
The high severization of system, the bearing safety stabilization to pile foundation proposes higher requirement.The mechanism and design of pile foundation vertical carrying are applied
Work is close to maturing, and the consideration on horizontal bearing performance turns into the key element of influence buildings or structures safety and effectivity.Pile foundation
Horizontal bearing is mainly controlled by a range of soil layer in top, and the non-linear of the soil body, layering, elastoplasticity are piles under lateral load
Where the difficult point of design.To improve pile foundation level bearing capacity, conventional method is mainly by increasing stake footpath, and increase pile body itself is firm
Degree, or the measures such as local stiffening are carried out come what is realized to Pile side soil body, often cost is too high for such way, and efficiency is low, and
It should not construct on a large scale.In terms of modern pile foundation development, also concentrate on to improve the novel pile that vertical bearing capacity is researched and developed mostly
Base, including support disk pile, bamboo joint pile, wedge pile, the stake of Y types etc..Above abnormal shape pile foundation is also right while vertical bearing capacity is lifted
The lifting of pile foundation level bearing capacity has been contributed, but is the problem of exist, and these pile-type must rely on special construction equipment, construction
Complex operation, pile quality is also relatively difficult to ensure card.
The content of the invention
Goal of the invention：For bored concrete pile horizontal bearing safety problem, the present invention provides a kind of special, targetedly soft
Soil base bored concrete pile horizontal bearing reinforcement and its construction method.
Technical scheme：To achieve the above object, the technical solution adopted by the present invention is：
A kind of soft soil foundation bored concrete pile horizontal bearing reinforcement, including the wing plate of one group of structure and size all same and one
Hoop, wing plate is evenly arranged on the week side of boss of hoop, wing plate and is provided with aperture；The wing plate be class fillet trapezoid, wing plate it is short
While being provided with neck, the double wedge consistent with wing plate quantity is circumferentially evenly arranged with hoop, passes through card between wing plate and hoop
The gap of groove and double wedge coordinates realization to be hinged；When not by external force, the wing plate freely hangs, and wing plate can be real with respect to hoop
Rotation in the range of existing 90 °, i.e.,：Wing plate upper surface make it that wing plate is inside by downward pressure, is rotated down, when rotation is to most
During big position, the angle of wing plate and hoop vertical plane is designated as α, 0≤α≤5 °；Wing plate lower surface is upwarded pressure so that the wing
Plate is outside, rotate up, and when rotation is to maximum position, the angle of wing plate and hoop vertical plane is designated as β；α<β≤90°.
Specifically, when the angle of wing plate and hoop vertical plane is α, there is overlap joint between adjacent two panels wing plate；Faying surface
Product is more than the 1/4 of monolithic area of foil, and preferably overlapping area is 1/3.
Specifically, when the angle of wing plate and hoop vertical plane is β, overlap joint is still suffered between adjacent two panels wing plate.
Specifically, the hoop is the structure of two sections of semi-rings, rotatable hinge is realized in one end of two sections of semi-rings by rivet
Connect, the other end of two sections of semi-rings realizes dismountable connection by latch.
Specifically, being provided with ribbing muscle on the wing plate.
A kind of construction method of soft soil foundation bored concrete pile horizontal bearing reinforcement, comprises the following steps：
Step1：Release latch connection, hoop open in the case of, wing plate is installed on hoop, check wing plate around
The rotation situation of hoop, it is ensured that mutual overlap joint and synchronization between adjacent vanes open, being condensed property；
Step2：Hoop and wing plate are integrally enclosed and are suspended on steel reinforcement cage, the connection of latch is closed, while by iron wire by ring
Colligation is bound round to the cage bar of steel reinforcement cage；
Step3：Hoop, wing plate and steel reinforcement cage are integrally transferred into drilling specified location, under after the completion of steel reinforcement cage is disposed
Put Grouting Pipe；
Step4：The slip casting into drilling by Grouting Pipe, slurries from slip casting bottom of the tube to Grouting Pipe outside outflow and back up
Rise, wing plate opens under the uplift pressure that slurries go up, into umbrella shaped support in drilling；
Step5：Continue slip casting, the wing plate of vertically arranged all different depths is all opened；
Step6：Slip casting terminates, and all wing plates and hoop are finally wrapped up by slurries to be solidified, and is collectively forming and is conducive to pile foundation water
The reinforced-concrete reinforcement of flat carrying.
Specifically, in view of pile foundation level carrying is controlled primarily by top a range of pile-soil interaction influence, because
This described wing plate can be arranged only in the range of 5 times of bore diameters on pile foundation top.
Beneficial effect：Soft soil foundation bored concrete pile horizontal bearing reinforcement and its construction method that the present invention is provided, are solved
Long-standing bored concrete pile horizontal bearing capacity lifting is wasted with the single cost brought by increase stake footpath and special-shaped pile foundation again must
Contradiction between must being equipped by special construction；The inventive method is collectively forming level using wing plate, hoop and grouting concrete and held
Reinforcement is carried, the lifting of bored concrete pile horizontal bearing capacity is realized, vertical bearing capacity is also enhanced, and without specific pile foundation construction dress
Standby, installation method is simple, efficient quick.
