Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a bored interlocking mixing pile wall. Background Art

[0002] The construction of underground foundation pit pile wall is a common construction process. In this construction process, common retaining structures include: ordinary bored piles, cement soil mixing piles, SMW piles, underground continuous walls, full-casing cast-in-place piles (concrete) interlocking piles, etc. Ordinary bored piles have low shear strength, poor safety and water interception performance, and have a greater impact on environmental protection; cement soil mixing piles occupy a large construction site and have low overall stiffness. In order to make up for the lack of strength and stiffness, the volume of the pile body can only be increased; the construction process of SMW piles is relatively complicated, the wall quality and overall stiffness are not ideal, and they are only used as temporary structures; the construction process of underground continuous walls is relatively complicated, the mud has a great impact on the environment, and there is a high reinforcement ratio, so the cost is relatively high; full-casing cast-in-place piles (concrete) interlocking piles are more environmentally friendly, have ideal overall stiffness, better anti-seepage effect, and relatively high cost.

[0003] In order to solve the problems existing in this technology, the applicant made technical improvements on cement soil piles in 2006 and applied for patent number CN200620019434.7, the patent name is "Full casing cast-in-place pile bite cement soil pile", which "interlocks the side wall of the full casing cast-in-place pile with the side wall of the cement soil pile to form an integral combined pile". This utility model has high overall rigidity, good anti-leakage effect and low cost. However, with the progress and development of current construction technology and the complexity and diversification of construction environment, this technology has problems such as narrow application range and backward construction technology, such as:

[0004] (1) Drilling technology is changing with each passing day, and a full set of cast-in-place piles is not suitable for all construction environments;

[0005] (2) With the development of construction technology, the construction methods and equipment of mixing piles have also made great progress, and the structure of the piles has also been adjusted, so the previous construction technology also needs to be improved accordingly;

[0006] (3) During the construction process, the structure of the pile body will also diversify, and the current existing technology cannot adapt well to this change.

[0007] Therefore, we need to further improve our technology in order to better adapt to the needs of modern pile foundation construction. Utility Model Content

[0008] The purpose of the utility model is to provide a pile wall structure that meets the needs of modern construction, has a wide range of applications, better universality, better strength, and high economic benefits.

[0009] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a bored interlocking mixing pile wall, including reinforced concrete piles and interlocked piles, the reinforced concrete piles and the interlocked piles are interlocked to form an integral composite pile wall, and the composite piles are one of type A, type B, type C, type D, type E, and type F.

[0010] Furthermore, an I-shaped steel is arranged in the middle of the engaged pile.

[0011] Furthermore, the engaged piles are cement soil piles or solidified soil piles.

[0012] Furthermore, the diameters of the reinforced concrete piles and the interlocking piles are 600 mm to 2500 mm.

[0013] Furthermore, the diameters of the reinforced concrete piles and the interlocking piles are 1300 mm to 2500 mm.

[0014] Furthermore, the reinforced concrete pile 1 and the engaged pile 2 are on the same foundation pit excavation surface 4 plane.

[0015] The beneficial technical effects of the utility model are:

[0016] (1) The utility model adopts a mechanism in which reinforced concrete piles and engaged piles are engaged with each other, thereby ensuring the strength of the wall, reducing the reinforcement ratio, reducing the construction cost, and achieving better anti-leakage effect;
