In a busy neighborhood of Monterrey, Mexico, a yellow horizontal directional drill is working quietly. Traffic runs as usual on the surface, while underground, brand-new water supply pipes are passing through accurately. This equipment is the hdd boring machine imported by a local engineering company last month. With its help, the pipeline project that originally required road closure and excavation for two months was successfully completed in only two weeks.【WhatsApp/WeChat/Phone】+86 13837122632

Project Background
Earlier this year, Monterrey, Mexico launched a water supply network renovation project, which needs to lay a 1.2-kilometer PE pipe with a diameter of 400mm. The project involves:
Main traffic roads: If excavated, the roads would be closed for months, seriously affecting citizens’ travel.
Historic districts: Some sections are in old town, and ground excavation may affect the foundations of surrounding old buildings.
River crossing: The pipeline needs to cross a seasonal river, making traditional excavation difficult.
After comparing various directional drilling equipment, the customer finally chose YG products for the following reasons:
Trenchless construction to solve traffic problems: The biggest advantage of hdd boring machine is that it does not damage the road surface. With heavy traffic along the Monterrey project, construction without road closure is crucial for the local government and residents.
Adaptable to complex geology: Monterrey is on the edge of mountainous areas, with mixed soft soil, sand and hard rock underground. YG equipment can adaptively work in hard rock and automatically adjust drilling parameters without changing equipment.
High construction accuracy: The pipeline must pass between existing cables and sewers with a deviation within 10cm. Equipped with ultra-deep guidance monitoring system, operators can adjust the drill direction in real time to avoid obstacles accurately.
Self-contained anchoring system: The ground is soft at some Mexican sites, and traditional rigs need extra anchor pouring. YG equipment has a built-in anchoring system and can work immediately upon arrival, saving preparation time.
High degree of automation: Automatic drill rod stacking, extraction and lubrication reduce manual assistance time. Local workers can operate after brief training.
Practical Application of HDD Boring Machine
After the equipment arrived in Mexico, we completed commissioning via remote video guidance, and then it was put into construction. Here are several typical application scenarios:
Crossing main roads: The pipeline needs to cross a two-way six-lane highway. With open excavation, half the road would be closed for two months. hdd boring machine drills from one side and passes 5 meters underground without affecting traffic.
Working in historic districts: Narrow streets in old towns make it hard for large machinery to enter. The compact equipment (only 5.7 meters long) turns flexibly at street corners and successfully completes 300 meters of pipeline laying.
River crossing: The pipeline crosses 8 meters under the riverbed. The equipment controls depth accurately through the guidance system, avoids cobblestone layers and drills in stable rock to ensure long-term safety.
Night construction in downtown: Some sections are crowded in the daytime, so construction is arranged at night. The low-noise design meets Mexican environmental standards and causes no complaints.
After project completion, the customer’s project manager sent detailed feedback:“We are very satisfied with the performance of this hdd rig machine. We were most worried about the hard rock section, but the equipment handled it automatically without any trouble. The whole construction period was only half of the plan.”The customer specially mentioned that the equipment impressed them deeply when crossing the river — the drill emerged exactly at the designed position with an error of less than 5cm. The high precision of directional drilling equipment has been fully verified.
Construction Tips for HDD Boring Machine in Different Geologies
Based on actual construction experience of Mexican customers, we summarized operation points for hdd rig machine under several geological conditions:
Hard rock formation:
Reduce drilling speed and keep uniform advancement
Increase mud flow to ensure hole cleanliness
Use wear-resistant drills; YG equipment’s adaptive function can automatically adjust torque
Sandy geology:
Increase mud viscosity to prevent hole collapse
Carry out reaming step by step, with each increase not exceeding 100mm
Work continuously during pipe pulling without stopping
Soft soil area:
Control mud pressure to prevent ground uplift
Reduce reaming diameter properly to reduce soil disturbance
Ensure anchoring stability; the YG self-contained anchor can automatically adjust grip
Cobblestone layer:
Use tapered drills to reduce sticking risk
Increase mud flow speed to remove gravel in time
Reduce thrust during guiding, mainly by rotation
River crossing:
Control depth 6–18 meters under the riverbed for natural anti-corrosion
Increase guidance monitoring frequency to keep the drill in the intended formation
Fully ream before pulling back to ensure smooth pipe passage
These skills help customers fully utilize the performance of directional drilling equipment under different geological conditions and ensure smooth construction.
