Embodiment Construction

[0020] The present invention will be further described below in conjunction with accompanying drawing.

[0021] Such as figure 1 As shown, the present invention provides an earthwork backfill tamping device under a ground beam, which includes a briquetting block 2 fixed on the ground beam 1, and a traveling mechanism and an actuator are arranged on the briquetting block. The walking mechanism is set between the pressing block and the ground beam, and is used to move the pressing block installed on the bottom beam to a suitable position and fix it at this position; one end of the actuator is installed on the pressing block, and the other end acts on the ground backfilling The vibrating roller 3 is installed on the soil, and the trajectory A of the vibrating roller is set by the actuator, so that the vibrating roller reciprocates in the trajectory, thereby realizing the compaction of the backfill. In some embodiments, the earthwork backfilling and compacting devices under the g...

Abstract

The invention discloses an earthwork backfilling and tamping device under a ground beam. The earthwork backfilling and tamping device is characterized by comprising a pressing block fixed on the ground beam, a walking mechanism arranged on the pressing block and used for moving the pressing block, and an executing mechanism used for compacting backfill soil; the walking mechanism is arranged between the pressing block and the ground beam; one end of the executing mechanism is connected with the pressing block; a vibration compression roller used for tamping the backfill soil is arranged at the other end of the executing mechanism and acts on the backfill soil on the ground; and the executing mechanism controls the vibration compression roller to do reciprocating motion in a preset track, so that the purpose of compacting the backfill soil is achieved. When the device is used for compacting the backfill soil under the ground beam, the backfill work under the beam can be quickly completed by only clamping the device with the ground beam, positioning the position of a main rotating arm through a supporting hydraulic cylinder arranged on the device and combining a rotating arm hydraulic cylinder and the vibration compression roller, the compaction degree of the backfill soil can be ensured, and the backfilling quality is good. The device is simple in structure, can be repeatedly used in foundation beam backfilling in the building industry, and is high in universality.

Description

technical field [0001] The invention relates to the technical field of application of construction engineering equipment, in particular to a device for backfilling and compacting earthwork under ground beams and a method for using the same. Background technique [0002] When backfilling the foundation beam, due to the limited upper space, it is difficult to compact the earthwork under the beam, and the poor quality of earthwork backfilling under the beam often leads to subsidence and cracking of the foundation ground. Traditionally, the backfill soil is watered to let it sink naturally, and the backfill soil beside the beam is compacted with a frog-type tamping machine to make up for the defects of the backfill soil under the beam. However, in essence, it cannot meet the requirement of 0.92-0.95 compaction degree of backfill soil. After being soaked by rainwater, a cavity will be formed under the beam, and the surrounding soil will be washed away quickly, resulting in local ...
