Mainly applicable to geology

Cohesive soil: including loess, red soil, silty clay, etc., with low drilling resistance and high drilling efficiency.
Sand layer/gravel layer: Suitable for fine sand, medium sand, and gravel containing sand layers, combined with mud wall protection, can effectively prevent hole collapse.
Weathered rock layers: strongly weathered, moderately weathered sandstone, shale, limestone, etc., can be smoothly drilled through impact+cutting mode.
Loose rock layers: fractured rock layers and gravel layers with developed fissures, with better adaptability than pure hard rocks, requiring specialized drill bits.

Core strengths

Convenient mobility: The tire chassis is paired with a traction structure, eliminating the need for large equipment during transitions. It is suitable for complex outdoor road conditions such as rural and mountainous areas, and has high efficiency in short distance transportation.
Easy to operate: compact structure, simple control process, no need for a professional team, single or double person operation, quick to get started and easy to maintain.
Wide adaptability: able to cope with various soft geological conditions such as soil, sand layers, weathered rocks, etc., meeting the needs of small and medium-sized water wells for civilian drinking water, agricultural irrigation, etc.
Cost controllable: The equipment procurement and operation costs are lower than those of large tracked drilling rigs, with low energy consumption, simple daily maintenance, and reduced overall project investment.
Flexible and efficient: No complex installation or fixation is required during operation, and the support legs can be quickly leveled to start work. The drilling efficiency is stable and suitable for dispersed operations in multiple locations.

Poor stability, affecting drilling accuracy

Tires are "flexible load-bearing", and if the ground is slightly uneven during operation, the equipment is prone to slight shaking; Compared to tracked drilling machines (with adjustable leveling) or fixed drilling machines (with fixed bases), in scenarios that require high-precision drilling (such as some industrial water wells), the verticality of the hole wall and the consistency of the hole diameter may be slightly inferior.

Insufficient durability for long-term high-intensity operations

The original intention of designing moving parts such as tires and suspension systems is "convenient transition", rather than "long-term high-intensity load-bearing operations"; If high load drilling is carried out continuously for a long time (such as more than 10 hours of hard rock operations per day), the wear and tear of tires and suspension components will accelerate, and vulnerable parts need to be replaced more frequently. The long-term use cost and failure rate are higher than those of crawler or fixed drilling rigs designed specifically for high-intensity operations

Summary: "Scene Matching Degree" of Advantages and Disadvantages

The core value of a tire type water well drilling rig lies in its ability to achieve high flexibility and cost-effectiveness with limited drilling capacity, making it suitable for scenarios with shallow to medium depths, dispersed locations, and small to medium-sized needs; However, in scenarios such as deep wells, hard rocks, complex terrains, and high-intensity operations, its disadvantages will be magnified, and it is necessary to prioritize the use of tracked or specialized drilling rigs.
