Abstract
The utility model discloses a barrel shaped expanded toe pile shoe, which comprises an annular connecting fitting and an annular pile cutting tip. Annular internal and external bearing surfaces are formed at the interface position of the annular connecting fitting and the annular pile cutting tip. The radial width of the external bearing surface is larger than that of the internal bearing surface. The interface position of the bearing surfaces and the annular connecting fitting is provided with a water stop groove coordinated with a protection casing. The longitudinal section of the pile cutting tip is provided with an annular reinforcing rib whose shape is similar with that of the longitudinal section. The utility model provides a barrel shaped pile shoe structure with large bearing force, effective prevention of the water seepage and high intensity, and firm connection with the column shaft.
Description
(1) technical field
The utility model relates to a kind of shoe of civil construction project foundation pile, especially a kind ofly is used for the used shoe of immersed tube bored concrete tube stake.
(2) background technology
Immersed tube bored concrete tube stake is a kind of novel foundation pile, be double-barrel structure, the space is sealed by shoe in the bottom between the inner/outer tube, between inside and outside protection casing, form the wall chamber in the piling process like this, placing of concrete in the wall chamber, again protection casing is extracted, so just formed the foundation pile based on shoe, foundation pile is the cylinder of hollow, compares with traditional solid cylinder, under identical concrete amount, increased the diameter of foundation pile,, so just saved raw material so bearing capacity is much bigger, and shoe is ring-type, reduced resistance.
In the patent No. is 98233440.0, name is called in the utility model patent of " a kind of forced one-step pore-creating device that is used for the concrete barrel construction of subgrade ", relate to a kind of annular shoe of bitubular foundation pile, its lower end forms cutting edge, in work progress, reduced resistance like this, but concrete Cheng Zhuhou, because shoe and soil contact connect little, so bearing capacity is limited, in addition because shoe and inside and outside protection casing are airtight not enough, be prone to the infiltration phenomenon in the concrete casting process, influence the foundation pile quality, and the insufficient strength of shoe, other are connected with nothing between the shaft, certainly will influence the quality of shaft.So be necessary to design a kind of bearing capacity big, prevent to seep water and intensity is big, the tubular shoe that is connected firmly with shaft.
(3) summary of the invention
The utility model will solve the existing little shortcoming of tubular shoe bearing capacity, provides a kind of bearing capacity big tubular shoe.
The technical scheme that the prior art problem that solves the utility model is adopted is: a kind of tubular expanded bore pile boots, comprise that circular connector and annular stake cut point, both junctions form the inside and outside supporting surface of annular, and described outer supporting surface radial width is greater than supporting surface radial width in described.
Further, described supporting surface is provided with the water stopping trough that matches with protection casing with described circular connector junction.
Further again, described stake is cut and is distributed with the cyclic reinforcing rib similar to its vertical sectional shape on the sharp longitudinal section.
There have vertical described circular connector of perforation of reinforcing steel structural member and described annular stake to cut point to be inner, and described circular connector upper surface is stretched out in described reinforcing steel structural member extension.
Described for reinforcing steel structural member can be the reinforcing cage structure.
The cutting edge place cylinder that the point bottom is cut in described annular stake equates to inside and outside protection casing distance.
Supporting surface cooperates just with internal wall protecting casing in described.
The utility model has the advantages that: 1. outer supporting surface radial width has increased the contact area of shoe and soil like this greater than interior supporting surface radial width, and the bellend resistance has increased the bearing capacity of foundation pile; 2. supporting surface is provided with water stopping trough, and its interior first filling flexible material makes protection casing closely contact with shoe during construction in the pile driving process, can prevent infiltration; 3. owing to the effect of reinforcing rib, increased the intensity of shoe; 4. owing to the effect of reinforcing steel structural member extension, behind the pile, shoe and pile body are connected as a single entity, and make shoe become the part of pile body, have improved workmanship; Since the cutting edge position can determine according to actual needs, so applicable to the pile of the foundation pile of various soil properties; 6. interior supporting surface cooperates just with internal wall protecting casing, has increased effective value of steel, has saved section bar.
(4) description of drawings
To be that common shoe is vertical cut to view Fig. 1.
Fig. 2 is the utility model longitudinal cross-section view.
Longitudinal section view when Fig. 3 uses for the utility model.
(5) specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified:
As shown in Figure 2, a kind of tubular expanded bore pile boots comprise that circular connector 1 and annular stake cut point 2, and both junctions form the inside and outside supporting surface of annular, and outer supporting surface 3 radial width are greater than supporting surface 4 radial width in described.The water stopping trough 5 that supporting surface 3,4 and be provided with are matched with protection casing.The annular stake is cut on sharp 2 longitudinal sections and is distributed with the cyclic reinforcing rib similar to vertical sectional shape 10.
Have the reinforcing steel structural member 9 vertical circular connectors 1 that connect to cut sharp 2 inside with annular stake, reinforcing steel structural member 9 is a reinforcing bar.
Reinforcing steel structural member 9 has the extension to stretch out described circular connector upper surface.
The cutting edge 6 place cylinders that sharp 2 bottoms are cut in the annular stake equate to inside and outside protection casing 7,8 distances.Interior supporting surface 4 cooperates just with internal wall protecting casing 7.
During construction, with shoe place need the stake of construction position to go up after, filling flexible material 11 water stopping trough 5 in puts inside and outside protection casing 7,8, begins pile sinking then, arrive specify absolute altitude after, between inside and outside protection casing 7,8, pour into the standard configuration concrete in the cavity of formation.Irritate after satisfy condition, extract two steel pipe tubes, so just having formed is foundation pile at the bottom of the expansion of end upper joint pin body with the shoe.Such pile foundation has enlarged end resistance, makes pile foundation that bigger bearing capacity arranged.
Claims (9)
