Abstract
The utility model relates to a kind of steel pipe pile test pile casing isolation roller, and comprise riser, stiffener and roller, riser end face has groove, and groove floor matches with the roller bearing of roller; Two stiffeners are welded on the outer both sides of groove; The radius sum of the high and roller of riser is than the spacing be less than between interior casing and outer casing.The utility model riser radius sum ratio that is high and roller is less than spacing between inside and outside casing, and roller contacts both sides with pile lining and leaves excess room; Roller in a groove can transverse shifting, for roller and inside and outside casing contact surface provide larger activity space.Effectively can avoid filling holding card phenomenon, ensure the validity of test pile.Roller can be placed when transferring interior casing 1 temporarily, convenient transport.The utility model can provide blanketing effect, can ensure test pile reliability again.
Description
Technical field
The utility model relates to a kind of steel pipe pile test pile casing isolation roller.Be mainly used in highway bridge, railroad bridge and building harbour etc. to need to do in the field of steel pipe pile, drilled pile test pile.
Background technology
Test pile usually needs according to different soil layers, determines different test pile depth and places.In the soil layer not needing to do bearing capacity of foundation soil, adopt isolation roller to carry out inside and outside casing separation.In steel pipe pile or bored pile test pile process, normal needs arranges spacer assembly between casing in steel pile casting and test pile, but usually causes roller stuck because scarfing cinder is clean or casing circularity is defective and lost efficacy.
The roller of plain bolt and steel plate cutting that utilizes of usual employing can not adapt to the change of casing circularity, and can not provide the excess room required for roller displacement, test pile reliability is little.
Summary of the invention
The purpose of this utility model is for above-mentioned present situation, aims to provide one and can provide blanketing effect, can ensure again the steel pipe pile test pile casing isolation roller of test pile reliability.
The implementation of the utility model object is, steel pipe pile test pile casing isolation roller, and comprise riser, stiffener and roller, riser end face has groove, and groove floor matches with the roller bearing of roller; Two stiffeners are welded on the outer both sides of groove; The radius sum of the high and roller of riser is than the spacing be less than between interior casing and outer casing.
The utility model riser radius sum ratio that is high and roller is less than spacing between inside and outside casing, and roller contacts both sides with pile lining and leaves excess room; Roller in a groove can transverse shifting, for roller and inside and outside casing contact surface provide larger activity space.Effectively can avoid filling holding card phenomenon, ensure the validity of test pile.Roller can be placed when transferring interior casing 1 temporarily, convenient transport.
The utility model can provide blanketing effect, can ensure test pile reliability again.

Fig. 1 installs mode elevational schematic view of the present utility model;
Fig. 2 installs lateral side view of the present utility model;
Fig. 3 is riser and the stiffener structural representation of roller;
Fig. 4 is special roller structure schematic diagram of the present utility model.
Detailed description of the invention
With reference to the accompanying drawings in detail the utility model is described in detail.
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model comprises riser 3, stiffener 4 and roller 5, and riser end face has groove, and groove floor matches with the roller bearing 6 of roller 5; Two stiffeners are welded on the outer both sides of groove; The radius sum of the high and roller of riser is than the spacing be less than between interior casing 1 and outer casing 2.
Riser 3 cross section is trapezoidal, and bottom surface is welded on interior casing 1.Roller 5 is cast steel roller.The degree of depth of riser 3 end face institute recessing is greater than the twice of roller bearing diameter, and roller in a groove can transverse shifting, for the contact surface of roller and outer casing 2 and interior casing 1 all provides larger excess room.Effectively can avoid filling holding card phenomenon, ensure the validity of test pile.
Adopt the utility model, first shaping interior casing 1, riser machined grooves.First riser is welded to interior casing surface, and rear welding stiffener 4 is in the outer both sides of riser groove and pass through fillet weld seam with interior casing.
Produce in factory roller 5.After test pile drilling via formations, transfer outer casing 2, interior casing 1 adopts loop wheel machine to weld section by section and transfers, and is highly about to prevent in roller 5 to groove when entering outer casing 2, continues to transfer interior casing 1 when scroll wheel positions arrives outer casing 2.Carry out adjusting and settling without the need to pair roller 5 in test pile process.
The utility model riser radius sum ratio that is high and roller is less than spacing between inside and outside casing, and roller contacts both sides with pile lining and leaves excess room; Roller in a groove can transverse shifting, for roller and inside and outside casing contact surface provide larger activity space.Effectively can avoid filling holding card phenomenon, ensure the validity of test pile.Roller can be placed when transferring interior casing 1 temporarily, convenient transport.
The utility model can provide blanketing effect, can ensure test pile reliability again.
