Description

Technical Field

[0001] The utility model relates to the technical field of foundation treatment, in particular to a device for testing the influence range of static pressure compaction piles. Background Art

[0002] At present, when static compaction piles are used in engineering projects, they are mostly designed as plum blossom-shaped piles. During construction, the holes are formed by skipping rows and rows, but because the static compaction machine occupies a large area when working, the pile holes completed by static compaction cannot be filled in time. Due to geological uncertainties, even if the holes are formed by skipping rows and rows, the impact range of compaction may cause the pile holes that are not filled to collapse. This requires increasing the spacing between holes.

[0003] Generally, the hole spacing will be increased, such as skipping two rows and two columns, which will seriously affect the construction progress. Therefore, it is particularly important to determine the reasonable hole spacing and choose the appropriate hole sequence. Therefore, a method for testing the influence range of single piles in static pressure compaction drilling is studied. Utility Model Content

[0004] The purpose of the utility model is to provide a device for testing the influence range of static pressure compaction piles to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: a device for checking the influence range of static pressure compaction piles, which is arranged on the ground and used for static pressure drilling of static pressure compaction piles, comprising:

[0006] A positioning line is arranged on the static pressure compaction pile position and is used for being arranged on the static pressure compaction pile position.

[0007] An observation structure is arranged on the positioning line and is used for observing the static pressure compaction pile position static pressure hole forming.

[0008] Preferably, the observation structure includes an observation hole opened on the positioning line, and a protection tube arranged on the observation hole for protecting the observation hole, and the observation structure is used to observe the static pressure compaction pile position after static pressure drilling.

[0009] Preferably, a guard plate is provided on the protection tube, and the guard plate is used to prevent the observation hole from being damaged when the protection tube and the observation hole are connected. The protection tube can effectively prevent the observation hole from collapsing.

[0010] Preferably, the size of the protection tube is smaller than the observation hole, so that the protection tube can be easily inserted into the observation hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are: the device for testing the influence range of static pressure compaction piles is simple to implement, and the influence range of pile formation can be determined once before construction, and the pile formation sequence can be reasonably selected, which can reduce the collapse of adjacent pile holes due to the small pile hole spacing. It can well ensure the quality of the project, and also avoid the delay of progress when a larger pile spacing is selected. BRIEF DESCRIPTION OF THE DRAWINGS
