Problems solved by technology

However, it is often difficult to find the pre-embedded steel pipes after the formwork is removed due to the deformation of the formwork, construction disturbance or nozzle protection, and insufficient reinforcement of embedded parts; especially in caverns with thicker linings, it is common that they cannot be found

Embodiment Construction

[0018] Such as figure 1 As shown in the figure, a search device for embedded concrete parts is a strong magnetic combination formed by natural adsorption of more than two powerful magnets. The ferromagnetic assembly includes a first ferromagnetic block 1 and a second ferromagnetic block 2, wherein a pull ring 3 is arranged on the larger ferromagnetic block.

[0019] A search method for concrete embedded parts, combining at least two strong magnetic blocks to form a strong magnetic combination, using the strong magnetism of the strong magnetic combination to attract iron embedded parts to the embedded concrete structure surface 4 When scanning the strong magnetic assembly on the concrete structure surface 4, find out the exact position of the embedded parts by feeling the direction, path and strength of the attractive force.

[0020] Specifically include the following steps:

[0021] Step 1: Naturally absorb and combine two strong magnetic blocks, ie, the first strong magneti...

Abstract

The invention discloses a concrete embedded part finding device and method. At least two strong magnets are combined into a strong magnetic combined body, the strong magnetism of the strong magnetic combined body is used for generating attraction force on an iron embedded part, the embedded part embedded in a concrete structure face is found, and when the strong magnetic combined body is swept on the concrete structure face, the accurate position of the embedded part is found by sensing the direction, the route and the strength of the attraction force. The concrete embedded part finding device and method has the advantages that operation is simple and convenient, the accurate rate is high, and cost is low; the construction efficiency can be improved; meanwhile, the repairing cost generated when the concrete surface is damaged due to blind finding is reduced.

Description

technical field [0001] The invention relates to a device and method for searching for embedded concrete parts, and relates to the field of cavern lining and grouting construction of hydropower and water conservancy projects. Background technique [0002] In the construction of cavern lining and grouting in hydropower and water conservancy projects, steel pipes are usually pre-embedded in the lining concrete to facilitate backfill grouting or consolidation grouting in the later stage. One end of the pre-embedded steel pipe touches the bedrock surface, and the other end touches the surface of the formwork, and the steel pipe at one end that reaches the formwork surface is filled with butter and painted with red paint for marking. After the formwork has been removed, find the cast-in spout by looking for paint and butter marks or by tapping. However, it is often difficult to find the pre-embedded steel pipes after the formwork is removed due to the deformation of the formwork,...
