Description

Technical Field

[0001] The present invention belongs to the technical direction of compaction pile treatment methods, and specifically relates to a compaction pile treatment method. Background Art

[0002] This patented invention is applicable to the construction of both plain soil compaction piles and cement soil compaction piles for the project. The design drawings specify that plain soil compaction piles and cement soil compaction piles be used for foundation treatment. Based on the compaction pile construction process, an environmentally friendly compaction pile driver is used to drill holes. After acceptance, a tamping machine is used for layered backfilling. The backfill is mixed on-site with plain soil or cement soil. This makes backfill quality control difficult, requiring dedicated on-site supervision and resulting in significant dust pollution. To prevent cement soil from clumping, a mix-as-you-go method is generally adopted, with a low tamping rate, severely restricting the construction schedule.

[0003] Compaction pile construction generally uses an environmentally friendly compaction pile driver to drill holes, and then uses a tamping machine to backfill the holes in layers with plain soil or cement soil. This method requires strict control of the quality of the backfill material and the tamping quality, but the measurement during the mixing process is difficult to control accurately, the backfill rate is slow, and it is severely restricted by rainy and snowy days. In addition, someone must be arranged to supervise at all times.

[0004] In order to avoid the poor quality of compacted piles, the participants of the present invention have jointly improved a compacted pile processing method to address the above shortcomings. This method is based on the compacted pile diameter, simulates according to the design parameters, determines the filler parameters, compacts the pile in advance in the project, and makes a shaped filler with a height of 500 mm and a diameter 20 mm smaller than the hole diameter. Backfill is carried out on site, and the pores after backfilling are filled with cement slurry or chemical slurry. Summary of the Invention

[0005] The purpose of the present invention is to provide a compaction pile treatment method for existing devices to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for processing compacted piles, comprising the following steps:

[0007] S1: Pile driver hole forming;

[0008] S2: Steel pipe pile model making and placement;

[0009] S3: ramming machine backfills the filler;

[0010] S4: Remove the steel pipe pile model and separate the soil at each depth;

[0011] S5: soil parameter analysis at each depth range;

[0012] S6: Determine the molding filler parameters and gap filling liquid;

[0013] S7: Forming filler production;

[0015] S9: static load test;

[0016] S10: Molding filler parameter adjustment and processing production;

[0017] S11: Backfill construction at the construction site.

[0018] The present invention further illustrates that during the process of making and placing the steel pipe pile model in step S2, the steel pipe pile model is designed and made of 10 mm thick steel plates, and is fixed with detachable pins around it. After the traditional backfill method is completed, it is disassembled and the soil is taken out for parameter analysis.

[0019] The present invention further illustrates that, in the process of analyzing soil parameters in each depth range in step S5, the soil is analyzed by testing soil density, bearing capacity, etc. to determine the soil characteristics in each depth range.

[0020] The present invention further illustrates that in the process of determining the parameters of the forming filler and the gap filling liquid in step S6, the forming filler is composed of a lowered installation point and a gap filling liquid groove. During implementation, the parameter requirements of the forming fillers at different depths are determined according to the soil parameters within each depth range, and the parameters and type of the gap filling liquid inside the gap filling groove are determined.

[0021] The present invention further explains that during the static load test in step S9, a static load test is performed on the compacted piles after the formed filler and the gap filling are completed and solidification is completed, and the parameters of the formed filler are appropriately adjusted according to the static load test.

[0025] This compaction pile treatment method avoids inaccurate measurement, which may lead to inaccurate mixing ratio and uneven mixing, thus affecting the quality of the pile.

[0026] This compacted pile treatment method uses the same size of molding seasoning to help check whether the pile length reaches the designed length and ensure construction quality;

[0027] This compacted pile treatment method uses a formed filler with a diameter 20mm smaller than the hole diameter for construction, which can help check the pile diameter deviation and repair the parts that do not meet the requirements;

[0028] This compaction pile treatment method can also check whether there are pile quality defects such as shrinkage holes and collapse holes during the filling process;

[0029] This compaction pile treatment method can increase labor input, shorten construction period, and avoid idle workers.

[0030] This compaction pile treatment method avoids the inability to mix fillers due to rainy days, and construction can be carried out immediately after the rain. BRIEF DESCRIPTION OF THE DRAWINGS
