Description

Basement construction backfill sieving device

Technical Field

The utility model relates to the field of building construction, in particular to a basement construction backfill soil sieving device.

Background

The basement of the building can be backfilled after construction, and backfill soil of the basement has certain requirements on the quality of soil. Thus, if the construction is carried out on the soil or the sandy texture, the excavated soil can be directly backfilled. However, in reality, large impurities such as stones are mixed in the soil which is often directly excavated. This requires screening the backfill to remove magazines.

In the present construction engineering construction, more often still rely on workman's manpower to sieve. For example, a worker picks out larger stones in the pile directly before backfilling. The existing backfill soil sieving device is generally sieved by using a reinforcing mesh or a big eye pocket mesh, and has the defects of easy damage, low sieving efficiency and inconvenient use in the sieving process.

Preferably, the base and the inclined support are made of channel steel through welding.

Preferably, the base, diagonal brace and frame are welded as a fixed whole.

Compared with the prior art, the basement construction backfill sieving device has the following beneficial effects:

backfill of a basement generally does not need to be screened very finely, only larger stones need to be removed, but the amount of earth needed to be screened is quite large. Therefore, a device is needed which can rapidly screen a large amount of soil and is suitable for construction on a construction site.

Therefore, the utility model designs a fixed sieving device formed by welding common steel materials on the worksite, and when the fixed sieving device is used, the soil needing sieving can be directly poured on the sieving surface by using engineering mechanical equipment such as an excavator forklift and the like. Greatly simplifies the manpower consumption of the soil sieving process and quickens the sieving construction time.

Detailed Description

The following describes specific embodiments of the present utility model in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the utility model, are not intended to limit the utility model.

In the present utility model, unless otherwise indicated, terms of orientation such as "up, down, left, right" are used to refer generally to up, down, left, right as shown with reference to fig. 2; "inner and outer" means inner and outer relative to the contour of the respective parts themselves. The present utility model will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

In order to solve the problem of how to rapidly screen the backfill of the basement, the utility model provides a basement construction backfill screening device, as shown in fig. 1 to 4.

The basement construction backfill sieving device comprises a sieving surface 1 and a supporting structure 2, wherein the sieving surface 1 is obliquely arranged on the ground, the supporting structure 2 supports the sieving surface 1, the sieving surface 1 is rectangular and comprises a frame 1a made of metal, a plurality of sieving rods 1b which are parallel to each other are fixed on the frame 1a, and the sieving rods 1b vertically extend and the upper end and the lower end of the sieving rods are respectively fixed on the upper edge and the lower edge of the frame 1 a; the supporting structure 2 comprises a base 2a which is horizontally placed on the ground, the bottom of a frame 1a of the sieving surface 1 is fixed on one side of the base 2a, an inclined support 2b is arranged on the other side of the base 2a away from the sieving surface 1, and the top of the inclined support 2b is propped against the top of the frame 1a of the sieving surface 1.

As shown in fig. 3 and 4, the screening device is in use fixed on the ground, then the excavator directly dumps the soil onto the screening surface 1, and then the screening bars 1b above the screening surface 1 block the larger stones. The stone will slide down to the bottom along the screening bars 1b. While the soil will pass through the screening bars 1b and fall under the projection of the screening surface 1. The screened soil is removed from the back of the screening surface 1 and backfilled into the basement.

The supporting structure 2 is a fixed steel frame structure welded by steel materials on the construction site, can be stably placed on the ground, and can fix and support the screening surface 1. The specific form may be determined by the specific material strength used and the size of screening surface 1 desired. The screening surface 1 is likewise fastened by a metal frame 1a, and the screening bars 1b are then arranged on the frame 1 a. The frame 1a only needs to have sufficient strength and not deform after being impacted by falling soil. Preferably, the steel is welded by steel such as square steel pipe or channel steel I-steel.
