A method for installing and using a protection device for fully buried vertically buried equipment

Abstract

The invention discloses a use method of an installation and protection device of fully-embedded vertical burying equipment. The installation and protection device comprises a bottomless box body and amovable upper cover; the construction method comprises the following steps that first-stage to-be-buried equipment is installed, and a first-layer buried material is buried; the buried material around the first-stage to-be-buried equipment is dug, the bottomless box body is covered on the first-stage to-be-buried equipment, and the movable upper cover is covered; a rope body is pulled outside therange of the landfill area, and a second buried material is buried; the rope body is lifted, the device is lifted to the surface layer of the second layer buried material, the movable upper cover isopened, the installation of the second-stage to-be-buried equipment is completed in a containing space of the bottomless box body, and the movable upper cover is covered after the installation is completed. According to the use method, the installation and protection device used in the invention is in a fully-embedded type, the operation surface is not exceeded all the time, a civil engineering operation vehicle or other construction machinery or heavy objects can freely pass above a buried part, for example, a paving machine can carried out paving normally, and a rolling machine can carriedout rolling compaction normally.

Description

technical field [0001] The invention relates to the field of safety monitoring in civil engineering operations, in particular to a method for installing fully buried vertically buried equipment and using a protection device. Background technique [0002] Shuoqu River Quxue Hydropower Station is located on the main stream of Shuoqu River, the largest tributary of Dingqu River, a primary tributary of Jinsha River. The dam type is a rockfill dam with asphalt concrete core wall, the crest elevation is 2334.2m, the maximum dam height is 164.2m, and the core wall is the largest The height is 132m, the bottom of the core wall is 1.5m thick, and the top is 0.6m thick. In order to monitor the deflection and deformation of the core wall, three sets of array displacement gauges SAA are arranged in the material transition area adjacent to the downstream side of the core wall. In order to match the installation of three sets of array displacement gauges, inclinometer pipes and electroma...

AI Technical Summary

Problems solved by technology

[0004] 1. Steel drums can only be erected in the construction area, and equipment such as construction or rolling should be detoured

[0005] 2. Once the construction equipment collides with the steel drum, it will be difficult to recover

[0006] 3. During the data collection during the construction period, the data collection personnel need to climb onto the steel drum to perform measurements on the top of the steel drum, which poses a high safety risk and the quality of the collected data is not guaranteed

[0007] 4. Unable to adapt to the installation of the inclinometer pipe at the core wall of the core wall (because the core wall paver and rolling equipment must pass through this area)

[0008] 5. If the steel drum is extended, the installed inclinometer pipe is in a relatively closed space protected by the steel drum. The deformation of the dam body cannot be well transmitted to the inclinometer pipe, which will easily lead to distortion of the inclinometer data. At the same time, events such as the collision of external force on the tube hole and the occurrence of jamming caused by foreign matter falling into the hole occur from time to time

[0011] Another example is the Chinese patent application number 201710041392.X, which discloses a new type of steel sheet pile inclinometer tube installation protection device, which can completely wrap the inclinometer tube during construction to ensure that it is not damaged, and can be pulled out after construction The secondary use of the protective cover provides a reliable technical means to solve the problem of easy damage to the installation of the inclinometer tube in the flexible enclosure structure. Although the device mentions the protection of the inclinometer tube, it does not mention the extension and length of the inclinometer tube. The installation of the subsidence magnetic ring, and it must be attached to the steel sheet pile before it can be used, and it cannot be used independently. The working surface is the ground construction after the steel sheet pile is inserted and driven, and the construction is not filled with soil. The installation depth of the inclinometer is limited. The filling soil cannot be lifted up synchronously

[0012] In addition, the Chinese patent with the application number 201510245963.2 discloses a device for installing and protecting the inclinometer pipe for filling soil, its processing method and use method. The purpose of the device is to install the inclinometer pipe in the existing hole. The process is : Drilling → installation of monitoring pipes, which can be constructed independently and in a centralized manner, and can realize the protection of the inclinometer pipes in the filled soil, but the extension of the inclinometer pipes is not mentioned, and the progress of installing the inclinometer pipes cannot be compared with the progress of soil filling Keep consistent, during the use of its device, it cannot be accompanied by the operation of other construction machinery on the working surface

The Chinese patent application number 201610537823.7 discloses a construction method for installing layered settlement instruments in deep compressive soil layers. The construction method of the settlement instrument, which can solve the problem of distortion of the observation results caused by the additional settlement of the layered settlement instrument due to its own weight, does not mention the extension of the inclinometer tube and the protection of the orifice, and the construction machinery needs to bypass, the construction Machinery cannot be crushed or even collided with the device
