Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, specifically relates to a pile foundation hole mouth detachable operation protection device. BACKGROUND

[0002] In the field of building construction, pile foundation construction is the core link of infrastructure construction such as bridge engineering and house building, and its construction safety is directly related to the safety of on-site personnel and engineering promotion efficiency. As a key risk point in the construction process, the pile foundation hole mouth is prone to safety accidents such as personnel falling and objects falling and injuring the workers below due to its large hole depth and open exposure. Therefore, the hole mouth protection device has become an indispensable safety protection facility in pile foundation construction. With the continuous improvement of the requirements of the construction industry on construction safety, flexibility and construction efficiency, the traditional protection device has been difficult to meet the modern construction needs, and the research and development of a protection device with stability, versatility and convenience has become increasingly important.

[0003] In actual production and construction process, the existing pile foundation hole mouth protection measures have many outstanding problems. On the one hand, the fixed welding type protection device has certain structural stability, but due to the use of non-detachable welding connection method, it cannot be quickly adjusted or removed during the conversion process of different stages of pile foundation construction, and it is difficult to adapt to the construction requirements of multiple working conditions, and after the construction is completed, the device is difficult to recover, which easily causes material waste. On the other hand, the simple fence type or bamboo sheet covering type protection device is convenient to disassemble and assemble, but the structural strength is insufficient, the stability is poor, and the device is easy to damage or shift when facing personnel collision and bad weather, so it cannot form a reliable protection barrier, and the safety protection performance is difficult to guarantee. In addition, part of the protection device lacks flexible opening and closing mechanism, and needs to be disassembled as a whole when the hole mouth operation is needed, and then reinstalled after the operation is completed, which seriously affects the construction efficiency, and the repeated disassembly and assembly easily leads to the aggravation of device wear and tear.

[0004] According to the search and review of relevant information, in view of the above problems, there are currently various solutions to pile hole protection in the industry. Among them, the patent number CN211114933U, the patent name is a kind of detachable and reusable pile hole protection device, which puts forward the protection scheme combined by top circular component, bottom circular component, middle circular component and support rod, its principle is to realize the assembly and disassembly of the device by the insertion of the sleeve on each component and the support rod, and to form a three-dimensional protection structure by different diameter circular components, and the diameter of the top circular component is suitable for the size of the pile hammer, which can reserve the operation space during construction. The advantage of this patent is that the structure is simple, easy to disassemble and reusable, which effectively reduces the use cost, and the three-dimensional structure can play a certain safety reminding role; but the disadvantage is that the protection way is passive, lacks active opening and closing function, and the device needs to be placed on the hole during construction, which still limits part of the construction operation although the operation space is reserved, and only relies on the cooperation of the support rod and the sleeve to realize the fixation, the stability in complex construction environment needs to be improved. In addition, the traditional fixed welding type protection device forms a protective fence or cover by welding the metal frame and the operation platform, which has the advantages of high structural strength, strong stability and reliable protection barrier; but the disadvantage is that the flexibility is poor, which cannot adapt to different pile hole diameters, and cutting and secondary welding are needed during disassembly, which not only consumes time and effort, but also causes permanent damage to the device, which is difficult to reuse. Another simple fence type protection device forms a protective fence by assembling steel pipes and buckles, which realizes the quick connection and disassembly of steel pipes by buckles, and has the advantages of low cost and fast disassembly; but the disadvantage is that the protection height and strength are limited, and the safety protection reliability is insufficient, and the hole is not covered, which cannot prevent small objects from falling.

[0005] The above scheme improves the protection effect to some extent, but still has some shortcomings. The fixed welding type protection device cannot flexibly adapt to different construction requirements, and the safety and stability of the simple fence type protection device need to be improved.
