Problems solved by technology

However, the setting of the wires will cause inconvenience to the foundation pile construction, and installing the inclinometer sensor and the gyroscope sensor on the foundation pile and driving them into the soil together will undoubtedly increase the cost of the foundation pile construction. a waste of resources
And because the monitoring and early warning system still has problems such as non-reusability, high real-time monitoring cost, and inconvenient monitoring, there is an urgent need to develop a real-time monitoring and alarm device for prefabricated pile tilting that is convenient for construction, reusable, and low in cost.

Embodiment 1

[0025] Embodiment 1: A kind of prefabricated pile inclination real-time monitoring and warning device of the present invention, its structure is as follows figure 1 As shown, it includes a cabinet 1, a hook 2 and an alarm mechanism. The cabinet 1 is a transparent rectangular plastic box, and the upper part of the outside of the box is provided with a hook 2 and a loudspeaker 3; opening the top cover of the plastic box 1 can facilitate Replace the battery 15; the upper part of the chassis 1 is fixed with a connecting rod 4, see figure 2 , The bottom of connecting rod 4 has spherical groove 41. The lower part of the cabinet 1 is provided with a central shaft disk 10 , and the special-shaped rod 7 connects the central shaft disk 10 and the connecting rod 4 .

[0026] see image 3 . The central shaft disk 10 is a combination structure of a round rod 101 and a disc 103, the top of the round rod 101 has a tapered groove 102, and the central shaft disk 10 is fixed on the bottom o...

Embodiment 2

[0030] Embodiment 2: The working process of a prefabricated pile tilt real-time monitoring and alarm device of the present invention:

[0031] The first step: a notch 18 is set on the top of the prefabricated pile 17, and the device provided by Embodiment 1 of the present invention is hung in the notch 18 through the hook 2, as Figure 7 shown.

[0032] The second step: drive into the prefabricated pile 17, in the process of driving the prefabricated pile, after the prefabricated pile is inclined, the weight 9 moves towards the vertical plane indicated by the inclination of the prefabricated pile 17 under the action of gravity; It is a hemisphere, inserted into the spherical groove 41 at the bottom of the connecting rod 4, and the bottom end of the inverted cone of the special-shaped rod 7 is inserted into the tapered groove 102 of the central shaft disk 10. This structure enables the special-shaped rod 7 to wind around its own The central axis rotates freely, and the rotatio...

Abstract

The present invention relates to a precast pile inclination real-time monitoring and alarm apparatus, which comprises a cabinet and a suspending hook, wherein a connection rod is fixed on the upper portion inside the cabinet, the lower portion is provided with a center shaft disc, a special-shaped rod is connected with the center shaft disc and the connection rod, can rotate along the center axis, and is bound with a heavy hammer through a heavy hammer line, a mercury tank is fixed on the special-shaped rod, and an electrical apparatus box is fixed on the mercury tank. According to the present invention, when a precast pile inclines, the heavy hammer moves toward an inclined vertical plane of the precast pile under a gravity effect to drive the mercury tank fixed on the special-shaped rod to move toward the vertical plane; when a mercury tank inclination angle is equal to or more than a designed angle alpha, long copper wires and short copper wires in the mercury tank immerse into mercury, such that an alarm circuit is turned on, and an alarm alarms so as to prompt inclination state generation; and a flashing light flashes, and a direction of the flashing light can be observed so as to know an inclination direction of the precast pile. The apparatus has the following characteristics that: a structure is simple, the apparatus can be installed on the outer portion of the precast pile so as to easily achieve project construction, precast pile construction can be real-timely monitored and guided, and the apparatus can be reused so as to save construction cost.

Description

technical field [0001] The invention relates to a real-time monitoring and alarm device for prefabricated pile inclination. Background technique [0002] Pile foundation is an ancient foundation type. Pile technology has experienced thousands of years of development. Now, both pile foundation materials and pile types, or pile machinery and construction methods have undergone tremendous development, and a modern foundation engineering system has been formed. In some cases, the use of pile foundations can greatly reduce the workload on the construction site and the consumption of materials. With the continuous popularization and application of pile foundations, the problems of prefabricated piles in the construction process have gradually become prominent. Due to the uneven site and the non-vertical piles when the piles are stabilized, the foundation piles will tilt during the sinking process. When the inclination angle of the foundation pile reaches a certain angle, the fo...
