Description

Technical Field

[0001] This utility model belongs to the field of safety protection in bored pile construction, specifically relating to a gravity-type protective canopy for flying rocks during bored pile blasting. Background Technology

[0002] During the construction of manually excavated bored piles, high-voltage power lines, residential buildings, and temporary facilities are frequently encountered. Blasting is often required during the excavation process, and the resulting flying rocks can damage the bored piles and surrounding personnel and equipment. Existing protective technologies (devices) mainly focus on edge protection, offering limited protection against flying rocks from blasting, and their effectiveness is poor. Summary of the Invention

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a gravity-type protective canopy for blasted flying rocks that can prevent blasting debris, provide edge protection and rain protection, be disassembled and reused, save resources, reduce construction costs, and provide good protection against blasting debris from bored piles.

[0004] This utility model discloses a gravity-type protective canopy for flyrock from blasting of bored piles, comprising columns, an upper crossbeam, distribution beams, blasting sheets, a middle crossbeam, a lower crossbeam, guardrails, and connecting plates. The features are as follows: connecting plates are fixedly installed at the upper and lower ends of the columns, a connecting plate is fixedly installed below the upper crossbeam, the columns are bolted to the upper crossbeam via the connecting plates, several distribution beams are fixedly installed on the upper crossbeam, blasting sheets are laid on the distribution beams, the lower ends of the columns are hinged to the middle and lower crossbeams, and guardrail tubes are installed between the middle and lower crossbeams.

[0005] A steel plate was placed on top of the gun shell.

[0006] Several sandbags were placed on the steel plate.

[0007] The aforementioned columns are placed around the anchorage of the bored pile.

[0008] Compared with existing technologies, this utility model has significant advantages. As can be seen from the above technical solution: connecting plates are fixedly installed at the upper and lower ends of the column, and a connecting plate is fixedly installed below the upper crossbeam. The column is bolted to the upper crossbeam via the connecting plates. Several distribution beams are fixedly installed on the upper crossbeam, and blasting sheets are laid on the distribution beams. The lower end of the column is hinged to the middle and lower crossbeams, and a guardrail is installed between the middle and lower crossbeams. Four I-beams serve as the columns, with an upper crossbeam added to each column. Small channel steel is added to the upper crossbeam as distribution beams. Blasting protective blasting sheets (lower layer) and steel plates (upper layer) are installed on the distribution beams as the roof of the protective canopy. Sandbags are piled on the roof to increase the weight of the protective canopy, thereby resisting the impact of flying rocks generated during the pile drilling process and preventing flying rocks from scattering, thus protecting against blasting debris. The protective canopy also keeps rainwater out of the pile, providing a dry working environment for personnel working inside the pile. A 1.2m high central and lower crossbeams and guardrails are installed between the four columns for edge protection of the bored piles. This protective device provides integrated protection for manually excavated bored piles, primarily focusing on edge protection, protection against flying rocks from blasting, and protection against rainwater. Furthermore, all components of the device are prefabricated and reusable, saving resources and reducing construction costs. It achieves protection against flying rocks from blasting, edge protection, and rainwater, and is disassembled and reusable, saving resources, reducing construction costs, and providing excellent protection.

[0017] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, describes the specific implementation methods, structure, features, and effects of this utility model.

[0018] The purpose of this utility model and the solution to its main technical problem are achieved by the following technical solution:

[0019] This utility model discloses a gravity-type protective canopy for flyrock from blasting of bored piles, comprising: uprights 1, upper crossbeams 2, distribution beams 3, sandbags 4, blasting sheets 5, middle crossbeams 6, lower crossbeams 7, guardrails 8, connecting plates 9, steel plates 10, and bored pile locking joints 11. Its key feature is that connecting plates 9 are fixedly installed at the upper and lower ends of the four uprights 1, and connecting plates 9 are fixedly installed at the bottom of the two upper crossbeams 2. The four uprights 1 are bolted to the two upper crossbeams 2 via the connecting plates 9. Several distribution beams 3 are fixedly installed on the crossbeam 2. The distribution beams 3 are covered with blasting sheets 5. The lower ends of the four columns 1 are fixed with three sides by bolts, including the middle crossbeam 6, the lower crossbeam 7, and the guardrail tube 8. The lower ends of one column 1 are respectively hinged to the middle crossbeam 6 and the lower crossbeam 7. The guardrail 8 is installed between the middle crossbeam 6 and the lower crossbeam 7 to form a gate. The blasting sheets 5 are covered with steel plates 10. Several sandbags 4 are placed on the steel plates 10. The four columns 1 have a hole pile lock 11 in the middle.

[0020] When in use, refer to 6. Place the connecting plates 9 at the lower ends of the four columns 1 on the ground 12 and connect them with the anchor bolts. Fit the hole pile lock 11 onto the hole pile 13. Construction workers can open the guardrail 8 between the middle crossbeam 6 and the lower crossbeam 7 to enter the interior and carry out the hole pile 13 operation. When blasting occurs during construction, the impact of the flying rocks generated by the blasting hits the sandbag 4, which plays a role in protecting against flying rocks and also prevents flying rocks from "splashing". When it rains, rainwater falls on the sandbag 4 and cannot enter the hole pile 13. At the same time, the hole pile lock 11 prevents water from the ground from flowing into the hole pile 13. After the hole pile 13 is completed, remove the sandbag 4, steel plate 10, and blasting sheet 5. Remove the bolts, remove the two upper crossbeams 2 and several distribution beams 3, and then remove the anchor bolts and hole pile lock 11 respectively. It can be reinstalled for use in the next construction.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
