[0002] Grouting hydraulic auger is a commonly used engineering equipment, widely used in pile foundation construction, foundation reinforcement and deep foundation pit support in construction projects. Especially in complex geological conditions, such as soft soil, sandy soil, rock mixed strata, etc., it has high-efficiency drilling and grouting functions. However, traditional grouting drills have exposed the following problems during long-term use: 1. Insufficient equipment stability: The supporting structure design of traditional drilling rigs is relatively simple. Especially in unstable terrain or inclined sites, the equipment is prone to tilt or slip, resulting in reduced construction accuracy and even affecting the quality of the project.

[0003] 2. Uneven power transmission: Under high-load construction conditions, existing equipment may experience unstable power transmission due to insufficient support base design, resulting in reduced equipment operating efficiency and extended working cycle.

[0004] 3. Limited bearing capacity of the supporting structure: Traditional outrigger designs are often unable to withstand the dual pressure of equipment deadweight and operating load during high-intensity construction, which may cause structural deformation or damage.

[0005] 4. The connection structure is not firm: There is usually a problem of force concentration at the connection points between the chassis and the upper plate, and between the legs and the beam, which leads to loose connections, increased wear, and increased frequency of equipment maintenance and replacement.

[0006] In order to solve the above problems, there is an urgent need for an optimized support base structure that can not only ensure the stability of the equipment under complex terrain conditions, but also meet the load requirements of high-intensity construction, while having good power transmission performance and durability.

[0037] It should also be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.

[0038] The specific implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings.
