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] Such as figure 1 As shown, the vibratory compaction method in the backfill area in building construction includes the following steps:

[0048] Select the backfill soil and lay the backfill soil layer by layer into the foundation pit;

[0049] Every time a layer of backfill is laid, vibratory compaction is carried out once;

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

[0051] Vibrating and compacting the backfill, sucking out the moisture in the backfill through infiltration at a position with a high moisture content of the backfill, and injecting water into the backfill through direct water injection at a position with a low moisture content of the backfill;

[0052] A geogrid is placed under each layer of backfill soil.

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

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

Embodiment 2

[0065] Such as Figure 1-7 As shown, on the basis of applying the method of Example 1, this embodiment relates to a vibratory compaction device for a vibratory compaction method in a backfill area during construction, including a front compaction roller 1 and a power vehicle body 2. The compaction roller 1 is provided with a water content balance mechanism 4 , which is fixed with the front compaction roller 1 and extends from the front compaction roller 1 to the outer surface of the front compaction roller 1 .

[0066] In this embodiment, the determination of the water content of the backfill is determined by the conductivity of the backfill, and the measuring electrode 5 needs to be arranged on the front compacting roller 1 in addition to being arranged on the geogrid. The embodiment configures the measuring electrode 5 at the edge position of the front compaction roller 1, and the measuring electrodes 5 are arranged on both sides of the edge, so that the average value of the...

Abstract

The invention discloses a vibration compaction device and method for a backfill area in building construction, and the method comprises the following steps that: backfill soil is selected, and the backfill soil is laid into a foundation pit in a layered manner; vibration compaction is carried out once when a layer of backfill soil is laid; before the backfill soil is subjected to vibration compaction, the moisture content of the backfill soil is monitored in real time; the backfill soil is subjected to vibration compaction, moisture in the backfill soil is sucked out through permeation at the position where the moisture content of the backfill soil is high, and moisture is injected into the backfill soil through direct water injection at the position where the moisture content of the backfill soil is low; and a geogrid is laid below each layer of backfill soil. According to the method, the water content of the backfill soil in the area being subjected to vibration compaction is monitored and controlled, so that the vibration compaction effect is effectively improved.

Description

technical field [0001] The invention relates to the field of backfill area construction equipment, in particular to a vibratory compaction device and a vibratory compaction method for a backfill area during building construction. Background technique [0002] In building construction, the foundation pit needs to be backfilled. The commonly used backfill materials are gravel soil, sand and blasting ballast. These materials are laid in layers, and lime soil, loess, etc. need to be laid on top of these materials. , after backfilling, since the backfilling materials are relatively scattered, it is necessary to carry out comprehensive compaction on the backfilling area. The comprehensive compaction methods currently used mainly include the following types: static compaction, vibration compaction, impact compaction and vibration compaction, and tamping compaction. [0003] Among the many comprehensive compaction methods, vibratory compaction is relatively basic, but it also has a...
