Description

Technical Field

[0001] This utility model relates to a safety protection cover for a settlement monitoring point of a foundation pit support in a construction site. Background Technology

[0002] During the construction of foundation pits at building sites, numerous settlement monitoring points are required to monitor key parameters such as deformation and displacement of the pit support structure in real time. However, most existing settlement monitoring points are directly exposed to the complex and harsh environment of the construction site, making them susceptible to damage from dust, rainwater erosion, collisions with construction machinery, and trampling by personnel. This leads to damage to settlement monitoring markers and distortion of settlement monitoring data, seriously affecting the accuracy and reliability of foundation pit support settlement monitoring and posing potential risks to foundation pit construction safety. Currently, although some protective measures exist, they generally suffer from poor protective effects, inconvenient installation and dismantling, and poor applicability, making it difficult to meet the needs of actual engineering projects. Therefore, developing a safety cover that can effectively protect foundation pit support settlement monitoring points and ensure accurate and reliable settlement monitoring data is of significant practical importance. Summary of the Invention

[0003] The purpose of this utility model is to provide a safety cover for a settlement monitoring point of a foundation pit support in a construction site.

[0004] To solve the above problems, this utility model provides a safety protection cover for a settlement monitoring point of foundation pit support at a construction site, comprising: a safety protection cover, including: a 6mm thick steel plate pressure-resistant outer shell;

[0005] Furthermore, in the aforementioned safety protection cover for the settlement monitoring point of the foundation pit support at the construction site, the open end of the inverted U-shaped ring is located on both sides of the steel plate pressure-resistant shell, and the closed end of the inverted U-shaped ring extends out of the top surface of the steel plate pressure-resistant shell and has a preset length.

[0006] Furthermore, in the safety protection cover of the settlement monitoring point of the foundation pit support at the above-mentioned construction site, the height of the inverted U-shaped ring is greater than the height of the steel plate pressure-resistant outer shell.

[0007] Furthermore, in the safety protection cover of the settlement monitoring point of the foundation pit support at the above-mentioned construction site, the open end of the inverted U-shaped ring is welded to the contact position of the steel plate pressure-resistant outer shell as a whole.

[0008] Furthermore, the safety protection cover for the settlement monitoring point of the foundation pit support at the above-mentioned construction site also includes: an inverted U-shaped ring pre-embedded in the foundation pit support pile. The inverted U-shaped ring pre-embedded in the foundation pit support pile is tightly connected with the inverted U-shaped ring fixed to the steel plate pressure-resistant shell, and a common lock is used to pass through the two inverted U-shaped rings and lock them, and the key is kept safe.

[0009] Furthermore, in the safety protection cover of the settlement monitoring point of the foundation pit support at the above-mentioned construction site, the steel plate pressure-resistant outer shell and the inverted U-shaped ring pre-embedded in the foundation pit support pile are connected by iron chains and locks, and the connection is a detachable connection.

[0010] Furthermore, the safety protection cover for the settlement monitoring point of the foundation pit support at the above-mentioned construction site also includes: a layer of anti-rust paint applied to the surface of the steel plate pressure-resistant outer shell to prevent the steel plate pressure-resistant outer shell from rusting due to years of sun and rain exposure.

[0011] Furthermore, the safety protection cover for the settlement monitoring point of the foundation pit support at the above-mentioned construction site also includes: the ordinary lock is a commonly used lock. Considering that the gap between the inverted U-shaped ring embedded in the foundation pit support pile and the inverted U-shaped ring fixed to the steel plate pressure-resistant shell is slightly large, a chain lock can be used.

[0012] The technical effect of this utility model is as follows: a safety protection cover for a settlement monitoring point of foundation pit support at a construction site, wherein a 10mm inverted U-shaped ring is welded to each of the two pairs of sides of the safety protection cover, and the angle between the top of the inverted U-shaped ring and the ground reaches 70°, so as to make it easier to fit with the inverted U-shaped ring pre-embedded in the foundation pit support pile and to facilitate locking.

[0013] Unlike traditional protective covers for foundation pit support settlement monitoring points, which are simply made from templates on the construction site and connected to concrete with expansion bolts, these covers tend to rot or even break after long-term exposure to sun and rain, potentially burying the monitoring device or causing human or mechanical damage. This new type of safety protective cover for foundation pit support settlement monitoring points is made of custom-formed 6mm steel plates, offering high strength, and is coated with an anti-rust paint, enhancing its service life.

[0014] A 10mm round steel bar is welded to the middle of the top surface of the utility model steel plate pressure-resistant shell, and the surface is coated with a layer of anti-rust paint. This marks the position of the safety protection cover for the settlement monitoring point of the foundation pit support, preventing accidental damage by mechanical equipment or human error during construction. It serves as a reminder and further ensures the durability of the safety protection cover for the settlement monitoring point of the foundation pit support.

[0015] The safety cover used for settlement monitoring points in foundation pit support is detachable and reusable, reducing construction costs.

[0016] This utility model uses an inverted U-shaped ring pre-embedded in the foundation pit support pile and an inverted U-shaped ring fixed to the steel plate pressure-resistant outer shell, which is then locked with a lock. This prevents damage or movement of the safety cover due to mechanical equipment or human intervention, ensuring the durability and reusability of the safety cover, reducing costs. The safety cover itself is made of steel plate, which has high strength, ensuring that the safety cover will not be deformed during use and will not disturb the settlement monitoring equipment, thus ensuring the accuracy of settlement monitoring data.

This marks the location of the safety protection cover for the foundation pit support settlement monitoring point, preventing accidental damage by mechanical equipment or human error during construction. It serves as a reminder and further ensures the durability of the safety protection cover for the foundation pit support settlement monitoring point.

[0036] Specifically, Figures 1 to 2 The diagram shows a 45° axial view of the safety protection cover for the foundation pit support settlement monitoring point and an elevation view of the safety protection cover. It includes a steel plate pressure-resistant outer shell 1, inverted U-shaped rings (11, 14) welded (12, 15) on the side of the steel plate pressure-resistant outer shell 1, inverted U-shaped rings (2, 3) pre-embedded in the foundation pit support piles, iron chains (5, 6), locks (4, 7), and 171 10mm round steel bars 13 welded to the center of the top surface of the steel plate pressure-resistant outer shell 1. The diagram shows its structure and connection method in detail, and reflects the detailed connection and structure of the safety protection cover for the foundation pit support settlement monitoring point.

[0037] Figure 3 This is a detailed drawing of the safety protection cover for the foundation pit support. The steel plate pressure-resistant outer shell 1 includes: a steel plate pressure-resistant outer shell 1, inverted U-shaped rings (11, 14) welded (12, 15) with 171 10mm round steel bars 13 welded on both sides and the middle of the top surface of the steel plate pressure-resistant outer shell 1. The outer surface of the steel plate pressure-resistant outer shell 1 is coated with a layer of anti-rust paint. After the anti-rust paint dries, a layer of red and white alternating paint 16 is applied. The purpose of the round steel bars 13 and the red and white alternating paint 16 is to make the location of the safety protection cover for the foundation pit support settlement monitoring point conspicuous, so as to remind the on-site construction workers and construction machinery and equipment to pay attention and prevent the safety protection cover for the foundation pit support settlement monitoring point from being damaged by the on-site construction workers and construction machinery and equipment, thereby affecting the accuracy of the settlement monitoring data.

[0038] Figure 4 The diagram shows a cross-section of the inverted U-shaped rings embedded in the foundation pit support piles, including rings (2 and 3). During on-site construction of the foundation pit support piles, the inverted U-shaped rings (2 and 3) are welded to the main reinforcement of the foundation pit support piles. Before welding, the locations of settlement monitoring points and safety protection covers are planned, and the positions of the inverted U-shaped rings (2 and 3) are arranged reasonably. Depending on the actual distance, the inverted U-shaped rings can be welded to the main reinforcement of the foundation pit support piles in a π-shape. The length of the inverted U-shaped rings embedded in the concrete should be at least 1000mm to ensure the overall stability of the inverted U-shaped rings. 600mm of the inverted U-shaped rings should be exposed above the top surface of the foundation pit support piles.

[0047] Unlike traditional protective covers for foundation pit support settlement monitoring points, which are simply made from templates on the construction site and connected to concrete with expansion bolts, these covers tend to rot or even break after long-term exposure to sun and rain, potentially burying the monitoring device or causing human or mechanical damage. This new type of safety protective cover for foundation pit support settlement monitoring points is made of custom-formed 6mm steel plates, offering high strength, and is coated with an anti-rust paint, enhancing its service life.

[0048] The safety cover used for settlement monitoring points in foundation pit support is detachable and reusable, reducing construction costs.

[0049] This utility model uses an inverted U-shaped ring pre-embedded in the foundation pit support pile and an inverted U-shaped ring fixed to the steel plate pressure-resistant outer shell, which is then locked with a lock. This prevents damage or movement of the safety cover due to mechanical equipment or human intervention, ensuring the durability and reusability of the safety cover, reducing costs. The safety cover itself is made of steel plate, which has high strength, ensuring that the safety cover will not be deformed during use and will not disturb the settlement monitoring equipment, thus ensuring the accuracy of settlement monitoring data.
