Description

Technical Field

[0001] The utility model relates to the technical field of roadbed construction, in particular to a steel guide beam for roadbed pile-sheet wall construction. Background Art

[0002] In the construction of roadbed pile-sheet walls, the construction site needs to be leveled first, and then the foundation is poured on both sides of the area where the steel sheet piles are to be driven as needed. Subsequently, steel guide beams need to be erected on the foundation before the steel sheet piles are driven. At present, the erection of steel guide beams is carried out by temporary on-site lifting and connection. In the actual operation process, the support of the steel guide beams and the connection between the two adjacent steel guide beam segments are all installed on-site, resulting in the need to repeatedly measure and inspect the erected steel guide beams after installation to ensure that the steel guide beams are straight and meet the requirements of the pile driving operation. Due to the lack of effective auxiliary tools during the alignment of the steel guide beams, the alignment of the steel guide beams is relatively inconvenient. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] like Figures 1 to 5 As shown, a steel guide beam for roadbed pile-sheet wall construction comprises:

[0026] A support beam 1, the top of which is provided with a support plate 2 for supporting the steel guide beam segment;

[0027] A widthwise alignment block 3 is installed on the support plate 2 in a manner that it can be raised or lowered, and the widthwise alignment block 3 centers the steel guide beam segment on the support plate 2 by moving upward from the bottom of the support plate 2;

[0028] The lengthwise alignment block 4 is elastically supported on the support plate 2, and the top end of the widthwise alignment block 3 is arranged in a step shape, and the top surfaces of the two steps are respectively used to press down the butt ends of the two butt-jointed steel guide beam segments.

[0029] In the operation of erecting the steel guide beam, the support beam 1 is first arranged and fixed in sequence according to the segment length of the steel guide beam, and then the steel guide beam segment is directly hoisted onto the support plate 2 by using a crane. For the support plate 2 between the butt ends of the two steel guide beam segments, when placing the two steel guide beam segments one after another, the first steel guide beam segment to be lowered should be pressed on a step with a lower top surface height of the lengthwise alignment block 4. At this time, the side of a step with a higher height has a limiting effect on the end of the first steel guide beam segment to be lowered. The steel guide beam segment to be lowered later should be pressed on a step with a higher top surface height of the lengthwise alignment block 4. At this time, the end of the first steel guide beam to be lowered has a limiting effect on the end of the later steel guide beam to be lowered. Afterwards, the widthwise alignment block 3 is displaced upward on the support plate 2 to achieve alignment of the steel guide beam segment in the width direction.

[0030] When the steel guide beam segments on the support plate 2 are centered in the width direction, the inward side of the support plate 2 is flush with the inner side of the steel guide beam segments. At this time, it is ensured that there is enough gap between the two rows of steel guide beams for the steel sheet piles to be inserted.

[0031] The widthwise alignment block 3 includes a first part 3.1 and a second part 3.2 which are distributed up and down. The first part 3.1 is an isosceles trapezoidal structure, and the second part 3.2 is a rectangular structure. The width of the second part 3.2 is set to match the width of the inner cavity of the steel guide beam segment. During the upward displacement of the widthwise alignment block, the first part 3.1 compares the steel guide beam segment in the width direction through the inclined surfaces on both sides thereof. When the second part 3.2 moves into the bottom cavity of the steel guide beam segment, the alignment of the steel guide beam segment in the width direction can be achieved.

[0032] A height adjustment bolt 5 is installed at the bottom of the widthwise calibration block 2, and the height adjustment bolt 5 is threadedly installed on the support plate 2. By rotating the height adjustment bolt 5, the lifting and lowering of the widthwise calibration block 3 can be controlled.

[0033] The pallet 2 is provided with a first displacement groove 6 and a second displacement groove 7 for the up and down displacement of the widthwise alignment block 3 and the lengthwise alignment block 4, respectively. The widthwise alignment block 3 is slidably arranged in the first displacement groove 6, and the lengthwise alignment block 4 is slidably arranged in the second displacement groove 7. When the steel guide beam segment is placed on the pallet 2 in the initial state, the widthwise alignment block 3 is located below the pallet 2 to facilitate the lowering operation of the steel guide beam stage.

[0034] The bottom of the longitudinal alignment block 4 is connected to a first support spring 8, which is used to keep the height of the top surfaces of the two steps of the longitudinal alignment block 4 greater than the height of the support plate 2. In the initial state, the top of the longitudinal alignment block 4 extends to the area above the support plate 2. When the end of the steel guide beam segment is lowered, the end of the steel guide beam segment is aligned in the length direction using the step groove, so that the support plate 2 can be centrally supported below the butt ends of the two steel guide beam segments. A retractable fixing bolt 9 is provided at the top of the width alignment block 3, and a through hole for the fixing screw to pass through is provided on the steel guide beam segment, and when the steel guide beam segment is centrally distributed on the support plate 2, the top of the fixing bolt 9 passes through the through hole. A telescopic groove 10 for accommodating the fixing bolt 9 is provided at the top of the width alignment block 3, and a second spring 11 for pushing up the fixing bolt 9 is provided in the telescopic groove 10.

[0035] During the process of the widthwise calibration block 3 moving upward to calibrate the position of the steel guide beam segment in the width direction, the fixing bolt 9 is pressed down by the steel guide beam segment to be accommodated in the expansion slot 10. When the steel guide beam segment is centered, the through hole is aligned with the top end of the fixing bolt 9. At this time, the fixing bolt 9 passes through the through hole under the elastic action of the second spring 11, and then the fixing bolt 9 is connected with a nut, so that the steel guide beam segment can be fixed on the support plate 2.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
