Description
Technical Field
The utility model relates to the technical field of bored pile construction, in particular to a maintenance and stability system for bored pile construction.
Background
The bored pile is a pile formed by forming pile holes in foundation soil by means of mechanical boring, steel pipe soil squeezing, manual excavation or the like on an engineering site, placing a reinforcement cage therein and pouring concrete, and can be divided into a sinking pipe bored pile, a boring bored pile, a hole digging bored pile and the like according to different pore-forming methods. Bored piles generally comprise the following construction processes: firstly positioning a pile position of a cast-in-place pile, burying a steel pile casing, retesting and correcting deviation between the pile position of the cast-in-place pile and the pile casing center, drilling a hole by using a drilling machine, putting a manufactured steel reinforcement cage into the hole, fixing the steel reinforcement cage, pouring a guide pipe downwards, secondarily clearing the hole, pouring concrete, and dispatching a special person to measure the burying depth of the guide pipe, thereby completing pouring of the cast-in-place pile.
The bored pile is used as a non-soil-squeezing pile for improving the foundation, has the advantages of convenience in construction, high engineering progress, strong earthquake resistance and the like, and does not need large mechanical equipment, thereby being widely applied to foundation treatment construction. Generally, the hole digging pile is suitable for clay layers with less groundwater, powdery clay layers or clay layers with a small amount of sand gravel. When the hole digging pile penetrates through a backfill layer, a soft soil layer and a silt layer of the sand-containing gravel, on one hand, the water permeability of the stratum is high, the wall protection is easy to cause water seepage, and on the other hand, the stratum is mainly poor in self-stability due to the stratum, and holes collapse easily occurs in construction.
For this reason, when bored piles are drilled, steel casings are usually arranged at the openings to support weak strata, and are used for guaranteeing the verticality of the drilled holes. Because the soil layer is weak, the steel casing is easy to deform under the self-weight extrusion of the soil layer, and the weight of the steel casing is increased sharply due to the simple increase of the thickness of the steel casing, so that the extraction force of the steel casing when being taken out is greatly increased. Even if the reinforced steel pile casing can be pulled out, the concrete with high fluidity and high density can form an outward extrusion effect on a weak soil layer along with the pulling out of the steel pile casing, so that the diameter of a pile hole is increased, additional concrete is required to be used for casting, and the construction cost is additionally increased.
As another solution, it is generally simple to use clay compaction or to reinforce the soil layer around the steel casing by means of an adhesive modification. The method is simple and easy to operate, but has larger engineering quantity and higher cost. The scheme comprises the steps of using a first limiting rod, a second limiting rod, a third die, a fastening bolt, a first hoop, a second hoop, reinforced soil, grouting pipes and a steel plate. The related accessories can only be suitable for drilling with fixed aperture, different apertures need different three-petal molds and different steel plates, and the structure is complex, the cost is high, and the use is inconvenient.
Disclosure of Invention
The utility model aims to provide a maintenance and stability system for the bored pile construction, which has the advantages of improving usability, improving construction efficiency, reducing construction cost, and reducing the waste of concrete when the steel casing is pulled out without specially making a thickened steel casing.
In order to achieve the above purpose, the utility model provides a maintenance and stabilization system for bored pile construction, which comprises a pile casing and a soil layer reinforcing component; the pile casing and the soil layer reinforcing component extend along the vertical direction, and the soil layer reinforcing component surrounds the radial outer side of the pile casing and forms a limiting space with the pile casing; the soil layer reinforcing assembly comprises a plurality of reinforcing members arranged along the circumference of the casing, and each reinforcing member extends along the vertical direction.
According to the scheme, the soil layer reinforcing component is arranged outside the pile casing, so that the soil layer around the steel pile casing is divided into the inner soil layer and the outer soil layer, a curved path communicated with the inner soil layer and the outer soil layer is formed between two adjacent reinforcing members, and the flow resistance of the soil layer can be increased by the curved path. Because the internal diameter of soil layer reinforcement subassembly is greater than the external diameter of a casing, the compression that the soil layer in the limited spacing space can receive and the deflection that takes place is very little, therefore when extracting a casing, the concrete is difficult to expand along the radial of drilling, avoids additionally using the concrete to pour to save the concrete. In addition, the reinforcement enclosure such as I-steel has better pressure maintaining effect on the concrete poured in the reinforcement enclosure, and is beneficial to improving the structural strength of the poured concrete. Therefore, the pile casing is not required to be thickened, the soil layer around the pile casing is not required to be hardened and improved, and only the national standard I-steel or channel steel is required to be used as the reinforcing member of the soil layer reinforcing tool, so that the reinforcing member can be repeatedly used and can be suitable for different drilling apertures. Soil layer reinforcement can be completed only by inserting and pulling reinforcing members such as I-steel, and the method is simple and easy to operate, high in construction efficiency and low in cost. In addition, as the I-steel and the drill hole are separated by a barreled soil layer, even if the I-steel is pulled out after the cast concrete is solidified, the adhesion phenomenon of the concrete and the I-steel can not occur. Moreover, the contact surface of the single I-steel and the soil layer is far smaller than the contact surface of the protective cylinder and the soil layer, so that the extraction resistance of the I-steel is far smaller than the extraction resistance of the protective cylinder, the I-steel can be easily pressed into the weak soil layer by using a common static pressing machine, and the weak soil layer can also be easily driven into the weak soil layer by using a simple pile driver.
In one preferred embodiment, the maintenance system further comprises a reinforcing inner ring, wherein the reinforcing inner ring is arranged on the radial inner side of the soil layer reinforcing component and is close to the top end of the soil layer reinforcing component, and the reinforcing inner ring supports the soil layer reinforcing component in the radial direction.
Therefore, the supporting strength of the I-steel can be increased by reinforcing the inner ring, and the resistance strength of the soil layer reinforcing component for resisting the horizontal inward extrusion of the soil layer is increased.
Further, the height of the reinforced inner ring is in the range of 50 mm to 100 mm; and/or the wall thickness of the reinforcing inner ring is in the range of 20 mm to 40 mm.
It follows that since the axial height of the reinforcing inner ring is not high, it is easy to install even if the reinforcing inner ring is a little thick.
In one preferred embodiment, the dimensional stability system further comprises a reinforcing outer ring disposed radially outwardly of the soil layer reinforcing assembly and disposed proximate a top end of the soil layer reinforcing assembly, the reinforcing outer ring supporting the reinforcement in a radial direction.
Therefore, the supporting strength of the I-steel can be increased by reinforcing the outer ring, and the resistance strength of the soil layer reinforcing component for resisting the outward expansion of the soil layer is increased.
In a preferred embodiment, the reinforcement is an i-steel or a channel steel.
In a preferred embodiment, a curved path is formed between two adjacent reinforcement members; and/or the width of the meander is in the range of 10 millimeters to 80 millimeters.
Thus, the width of the curved road can be selected according to the softness of the soil layer, and the softer the soil layer, the smaller the width.
Preferably, the length of the reinforcement is equal to the length of the casing; or the length of the reinforcement is greater than the length of the casing, and the bottom wall of the reinforcement is lower than the bottom wall of the casing.
It can be seen that the casing penetrates through the weak soil layer, and the length of the reinforcing member is equal to that of the steel casing. Or the length of the reinforcement member is greater than the length of the casing so that the lower end of the reinforcement member may be inserted into a deeper, relatively stiffer formation to increase the overall horizontal slip resistance of the reinforcement member.
In a preferred embodiment, the number of soil layer reinforcing members is two or more, and the plurality of soil layer reinforcing members are arranged along the radial direction of the casing and coaxially arranged. In the soil layer reinforcing component at the innermost layer, two adjacent reinforcing members are mutually overlapped, and in other soil layer reinforcing components, the two adjacent reinforcing members are arranged at intervals.
Therefore, the mutually overlapped reinforcing members can provide supporting force mutually, strengthen bearing capacity mutually, and can also improve tensile strength in a mutually buckling mode, so that the bearing strength of the soil layer in the whole ring is increased. The upper ends of the I-steel between the two adjacent soil layer reinforcing components can be subjected to lap welding through steel bars or I-steel, so that the adjacent soil layer reinforcing components are mutually supported, and the overall strength of the soil layer reinforcing components is greatly improved. In the soil layer reinforcing component of the innermost layer, two adjacent reinforcing members are mutually overlapped, in other soil layer reinforcing components, two adjacent reinforcing members are arranged at intervals and are not required to be mutually overlapped to form a whole circle, so that the I-steel consumption and the construction workload are saved.
The further scheme is that the height of the pile casing is H, and the radius difference value of two adjacent soil layer reinforcing components is in the range of 0.1H to 0.5H.
