Description

Technical Field

[0001] The utility model relates to the field of foundation pit backfill, and specifically relates to a foldable guiding device for foundation pit backfill. Background Art

[0002] The fat groove refers to the space between the foundation pit supports after the completion of the construction of underground buildings such as underground stations, underground pipe galleries, and box culverts. The quality of the fat groove backfill is related to the integrity of building waterproofing, the stability of the building structure, and the landscape effect, etc. If the backfill is not carried out in time, it will not only increase the risk factor of the structure, but also affect the subsequent construction of municipal engineering, landscape engineering, etc.

[0003] For the earth backfill of the foundation pit fat groove, the specification requires manual backfill, but the manual backfill has low efficiency and is difficult to achieve for linear projects with a large backfill volume. Therefore, mechanical backfill construction is often used in actual construction. However, the earth volume of a single mechanical backfill is very large, which is easy to damage the building waterproof layer, resulting in rework or reducing the quality of the waterproof project, leaving hidden leakage problems, and it is also difficult to ensure the particle size of the backfilled soil, which is easy to affect the service life of the entire underground building. Content of the Utility Model

[0004] The purpose of the utility model is to provide a foldable guiding device for foundation pit backfill, which forms a guiding device for foundation pit backfill through a support rod, a connecting plate, a diversion plate and a leg, and can play a role in buffering and guiding the backfilled soil, so as to avoid damage to other finished products such as the waterproof layer while ensuring the construction efficiency, and form a good process connection.

[0005] In order to achieve the above object, the utility model is realized through the following technical solutions:

[0006] A foldable guiding device for foundation pit backfill, including a base, a pulley is provided at the bottom of the base, a handrail is provided on one side of the base, support rods are respectively hinged at both ends of the side of the base close to the handrail, a connecting plate is hinged on the side of the base away from the handrail, a diversion plate is hinged on the side of the connecting plate away from the base, a plurality of sieve holes are provided on the diversion plate, and legs are provided at both ends of the back of the side of the diversion plate away from the connecting plate.

[0007] Further, a cross bar is provided on the handrail, grooves are respectively provided at both ends of the cross bar, and the support rod can be fixed in the groove.

[0008] Further, a magnetic attraction block capable of magnetically attracting and cooperating with the support rod is provided in the groove.

[0009] Further, the support rod is a telescopic structure, and a fastening bolt for fixing the telescopic length of the support rod is provided on the support rod.

[0010] Further, the outrigger includes a connecting rod disposed on the deflector, and a backing plate is provided at one end of the connecting rod away from the deflector.
