Description

Technical Field

[0001] The utility model relates to the field of foundation pit protection equipment, in particular to a combined building construction foundation pit guardrail. Background Technique

[0002] In recent years, with the acceleration of the urbanization process and the continuous expansion of the scale of construction projects, the construction difficulty and complexity of foundation pit projects have gradually increased. As an important part of building construction, in order to ensure the safety of the construction site, the installation of guardrails for construction foundation pits has become a commonly used measure. Foundation pit guardrails usually include edge guardrails and safety nets, etc., aiming to prevent personnel from falling and objects from dropping during construction and ensure the safety of the construction site. However, with the improvement of construction site management requirements and the diversification of construction methods, the traditional design of foundation pit guardrails has gradually revealed some deficiencies and urgently needs to be improved and optimized;

[0003] In the prior art, the traditional design of foundation pit guardrails mainly relies on fixed guardrails. Such guardrails usually adopt steel pipes or reinforced concrete structures and are fixed around the foundation pit to achieve protection. However, this fixed guardrail has some significant defects in the actual construction process. First of all, due to the changes in the plane layout of the construction site and construction requirements, workers often need to enter the foundation pit to inspect and maintain facilities such as fire hydrants and distribution boxes, which requires the removal and restoration of the foundation pit guardrail. This process is not only cumbersome and time-consuming, but also the frequent removal and restoration are extremely likely to cause damage to the guardrail, increasing the maintenance and replacement costs.
