Description

Technical Field

[0001] The utility model belongs to the technical field of surcharge preloading construction for reclamation foundation, and particularly relates to a construction safety warning device. Background Technique

[0002] Surcharge preloading is a common ground treatment method for large-area soft foundation treatment. During the surcharge process, due to factors such as terrain, soft soil layer thickness, load, and construction interference, uneven settlement will inevitably occur. In the surface settlement monitoring of surcharge preloading soft foundation treatment projects, traditional manual monitoring methods are often used, by placing settlement markers on the surface.

[0003] In the prior art, the Chinese utility model patent with the authorization announcement number CN216432948U discloses an anti-overturning settlement plate for automatic monitoring of surcharge preloading settlement. Among them, a steel pipe (settlement pipe) is fixed inside the central hole of the settlement plate, and the upper end of the steel pipe extends upward through the surcharge layer. During the construction process, the height change between the upper end of the steel pipe and the reference plane is detected to obtain the settlement amount at the monitoring position. However, the upper section of the steel pipe is buried inside the surcharge layer, and there is a large friction between the steel pipe and the surcharge layer. When local settlement of the foundation occurs and the surcharge layer does not settle with it, the settlement plate and the steel pipe usually move down with the foundation. However, the existence of this friction force will affect the downward movement amplitude of the steel pipe, thereby affecting the monitoring accuracy.

[0004] Therefore, it is necessary to design a construction safety warning device that reduces the friction between the settlement pipe and the surcharge layer and ensures the settlement monitoring accuracy to solve the current technical problems. Summary of the Invention

[0005] Aiming at the deficiencies in the prior art, the utility model provides a construction safety warning device that reduces the friction between the settlement pipe and the surcharge layer and ensures the settlement monitoring accuracy.

[0006] The technical solution of the utility model is: a construction safety warning device, including a backing plate arranged on the top of the foundation. A settlement pipe is fixedly arranged in the middle of the top of the backing plate. A protection pipe with a length not less than the thickness of the surcharge layer is sleeved outside the settlement pipe. The settlement pipe extends outward from the upper end of the protection pipe, and the protection pipe is placed inside the surcharge layer.

[0007] A lubricating oil coating is arranged on the outside of the settlement pipe.

[0008] The length of the protection pipe is 300 mm larger than the thickness of the surcharge layer, and the settlement pipe extends outward from the upper end of the protection pipe by at least 100 mm.

[0009] A warning sign is erected corresponding to the settlement pipe at the top of the surcharge layer.

[0010] At both bottom ends of the warning sign, insertion rods are fixedly arranged, and the lower ends of the insertion rods are inserted into the top of the surcharge layer.

[0011] The backing plate is a steel plate body with a side length of 1000 mm and a thickness of 9 mm.

[0012] A protective cover assembly is arranged at the top end of the protection pipe.

[0013] The protective cover assembly has a transparent sleeve sleeved on the top end of the protection pipe, and a top plate is fixedly arranged at the top end of the transparent sleeve.

[0014] A retaining ring corresponding to the top end of the protection pipe is fixedly arranged inside the transparent sleeve.

[0015] Advantages of the present utility model:

[0016] In the present utility model, a protection pipe is added between the settlement pipe and the surcharge layer. The protection pipe is arranged inside the surcharge layer and is simultaneously slidably sleeved on the outside of the settlement pipe. The friction force between the settlement pipe and the protection pipe is small. When local settlement occurs in the foundation while the surcharge layer does not settle accordingly, the surcharge layer will not affect the settlement of the settlement pipe along with the backing plate, ensuring the accuracy of monitoring.

[0023] As Figure 1 and 2 As shown, the construction safety warning device includes a cushion plate 1 arranged on the top of the foundation 100. A settlement pipe 3 is fixedly arranged in the middle of the top of the cushion plate 1. A protection pipe 2 with a length not less than the thickness of the surcharge layer is sleeved outside the settlement pipe 3. The settlement pipe 2 extends outwards from the upper end of the protection pipe, and the protection pipe 2 is placed inside the surcharge layer 200; in this embodiment, a protection pipe 2 is added between the settlement pipe 3 and the surcharge layer 200. The protection pipe 2 is arranged inside the surcharge layer 200 and is simultaneously sleeved outside the settlement pipe 3 in a sliding manner. The friction force between the settlement pipe 3 and the protection pipe 2 is small. When the foundation 100 undergoes local settlement and the surcharge layer 200 does not settle accordingly, the surcharge layer 200 will not affect the settlement of the settlement pipe 3 with the cushion plate 1, ensuring the accuracy of monitoring.

[0024] In some embodiments, in order to further reduce the friction force between the settlement pipe 3 and the protection pipe 2, a lubricating oil coating is provided on the outside of the settlement pipe 3.

[0025] In some embodiments, the length of the protection pipe 2 is 300 mm greater than the thickness of the surcharge layer 200, and the settlement pipe 3 extends outwards from the upper end of the protection pipe 3 by at least 100 mm.

[0026] In some embodiments, a warning sign 4 is erected corresponding to the settlement pipe 3 at the top of the surcharge layer 200. On the one hand, the warning sign 4 can remind construction workers to avoid the settlement pipe 3 to prevent construction workers from colliding with the settlement pipe 3 and affecting the observation accuracy. On the other hand, it can remind the observers to easily find the position of the settlement pipe 3 for the convenience of settlement observation.

[0027] In some embodiments, insertion rods 41 are fixedly arranged at the bottom of both ends of the warning sign 4. The lower end of the insertion rod 41 has a taper, and the lower end of the insertion rod 41 is inserted into the top of the surcharge layer 200; specifically, the insertion rod 41 is a wooden rod, the warning sign 4 is a wooden board, and black and white stripes are painted on the warning sign 4.

[0028] In some embodiments, the cushion plate 1 is a steel plate body with a side length of 1000 mm and a thickness of 9 mm.

[0029] In some embodiments, as Figure 3As shown in the figure, a protective cover assembly 6 is provided at the top of the protective pipe 2. The protective cover assembly 6 can prevent impurities such as rainwater and sand from entering between the settlement pipe 3 and the protective pipe 2 during construction, increasing the friction between the two. When it is necessary to place a ruler on the top of the settlement pipe 3 to measure the settlement, the protective cover assembly 6 can be removed.

[0030] In some embodiments, as Figure 3 and 4 shown, the protective cover assembly 6 has a transparent sleeve 61 sleeved on the top of the protective pipe 2. A top plate 63 is fixedly provided at the top of the transparent sleeve 61. The transparent sleeve 61 can facilitate observing the position state of the end of the internal settlement pipe 3 through it. The top plate 63 seals the top of the transparent sleeve 61 to prevent sundries from entering.

[0031] In some embodiments, a retaining ring 62 corresponding to the top of the protective pipe 2 is fixedly provided inside the transparent sleeve 61. The transparent sleeve 61 is sleeved on the upper end of the protective pipe 2, and the retaining ring 62 abuts against the upper end of the protective pipe 2.

[0032] In some embodiments, both the protective pipe 2 and the settlement pipe 3 are galvanized steel pipes.
