Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiency that the vibration compaction effect is different in different areas due to the uneven distribution of the moisture content of the backfill soil when performing vibration compaction in the backfill area in the prior art, and provides a kind of backfill in construction. The vibratory compaction device and vibratory compaction method in the area can effectively improve the vibratory compaction effect by monitoring and controlling the moisture content of the backfill soil in the vibratory compaction area

Embodiment 1

[0047] like figure 1 As shown in the figure, the vibration compaction method of the backfill area in the building construction includes the following steps:

[0048] Select backfill and lay the backfill into the foundation pit in layers;

[0049] Each time a layer of backfill is laid, a vibration compaction is performed;

[0050] Before vibrating and compacting the backfill, monitor the moisture content of the backfill in real time;

[0051] Vibration compaction is carried out on the backfill, and in the position with high moisture content of the backfill, the moisture in the backfill is sucked out by infiltration, and in the position with low moisture content of the backfill, water is injected into the backfill by direct water injection;

[0052] Geogrids are laid under each layer of backfill.

[0053] The thickness of each layer of the backfill is 200-300mm.

[0054] In the practical application of this embodiment, the backfill soil is screened first, so that the moistur...

Embodiment 2

[0065] like Figures 1~7 As shown, on the basis of applying the method of Embodiment 1, this embodiment relates to a vibratory compaction device for a vibratory compaction method for a backfill area in construction, including a front compaction roller 1 and a power body 2. The compaction roller 1 is provided with a moisture content balance mechanism 4 which is fixed to the front compaction roller 1 and extends from the inside of the front compaction roller 1 to the outer surface of the front compaction roller 1 .

[0066] In this embodiment, the determination of the moisture content of the backfill soil is determined by the electrical conductivity of the backfill soil. The measuring electrode 5 needs to be configured on the front compaction roller 1 in addition to being configured on the geogrid. In the embodiment, the measuring electrode 5 is arranged at the edge position of the front compaction roller 1, and the measuring electrode 5 is arranged at the edges of both sides, s...

Abstract

The invention discloses a vibration compaction device and a vibration compaction method for a backfill area in building construction, comprising the following steps: selecting backfill soil, and laying the backfill soil layer by layer into a foundation pit; vibrating once for each layer of backfill soil laid Compaction; before vibrating and compacting the backfill, monitor the moisture content of the backfill in real time; perform vibration compaction on the backfill, and suck out the backfill through infiltration at the position with a higher moisture content of the backfill Inner moisture, where the moisture content of the backfill is low, inject water into the backfill through direct water injection; a geogrid is placed under each layer of backfill. The invention effectively improves the vibration compaction effect by monitoring and controlling the water content of the backfill soil in the vibration compaction area.

Description

technical field [0001] The invention relates to the field of backfill area construction equipment, in particular to a backfill area vibration compaction device and a vibration compaction method in building construction. Background technique [0002] In construction, the foundation pit needs to be backfilled. Generally, the backfill materials used are gravel soil, sand and blasting stone. These materials are laid in layers, and lime soil, loess, etc. need to be laid on top of these materials. , After backfilling, since the backfill material is scattered, it is necessary to comprehensively compact the backfill area. The comprehensive compaction methods currently used mainly include the following: static compaction, vibration compaction, impact compaction and oscillation compaction and tamping compaction. [0003] Among the many comprehensive compaction methods, vibration compaction is the more basic one, but it also has a good deep rolling effect. Vibration compaction is to ...
