Embodiment Construction

[0020] Attached below Figure 1~2 This embodiment will be described in detail.

[0021] The structure of this embodiment is as figure 1 As shown, a protection device for the top of an inclinometer pipe includes an iron cylinder 2 and a cylindrical cloth bag 3, both of which are in an inverted "U" shape; the top of the iron cylinder 2 is provided with an iron cylinder handle 4, and The inner diameter of the iron cylinder 2 is slightly larger than the outer diameter of the inclinometer pipe 1, so that it can be placed on the top of the inclinometer pipe 1 to be buried; There is lubricating oil, and the bottom of the cylindrical cloth bag 3 is longer than the bottom of the iron tube 2, and its pocket is bound on the inclinometer pipe 1 with iron wire.

[0022] Wherein in this embodiment, each component is specifically described as follows:

[0023] The inclinometer tube 1 is a commonly used inclinometer tube, and the inclinometer tube top cover 5 is matched with the inclinomet...

Abstract

The invention relates to a protective device for the top of an inclinometer pipe and a protective method thereof. The device comprises an iron cylinder (2) and a cylinder sack (3). At first, the iron cylinder (2) is sleeved on the top of the inclinometer pipe (1); and secondly, the cylinder sack (3) is sleeved outside the iron cylinder (2) and lubricant is coated between the iron cylinder (2) andthe cylinder sack (3). The iron cylinder (2) can protect the inclinometer pipe (1) from being damaged when pile heads are splited and top beams are prepared. The cylinder sack (3) can prevent concretes and the iron cylinder (2) from bonding together. The lubricant between the iron cylinder (2) and the cylinder sack (3) can ensure that the iron cylinder (2) can be smoothly pulled out. The invention has simple structure, easy operation, good practical effect and lowered cost, and is suitable for protecting the inclinometer pipe from being damaged.

Description

technical field [0001] The invention relates to a protection device for the top of an inclinometer pipe and a protection method thereof. Background technique [0002] In the stability monitoring of deep foundation pits and high slopes, it is often necessary to bury inclinometer pipes. The method of embedding the inclinometer pipe can be roughly divided into two types. 1. Borehole embedding: Use a 108mm drill bit to drill holes, and the hole depth must be greater than the depth of the pre-embedded inclinometer pipe. Then assemble the inclinometer tube and do a good job of sealing to prevent the infiltration of mud in the tube. Place the inclinometer pipe into the borehole while watering. Finally, the gap between the hole wall and the inclinometer tube is filled with cement mortar. 2. Embed together with the reinforcement cage: assemble the inclinometer tube and bind it on the reinforcement cage. Take protective measures for the bottom and nozzle of the pipe, adjust the o...
