Ultra-high pressure rotary jet drilling rig enters the station and makes new achievements

In mid-August, SEMW?SMJ-120 ultra-high pressure rotary jet drilling rig successfully solved the construction problems after appearing in the "Shanghai Central East New Project", now in the form of engineering relay battle, settled in the Xuhui District "Caohejing Beiyang Artificial Intelligence School" At the site of the "Town" project, relying on its strong product strength, it will accelerate the acceleration of the "Artificial Intelligence Highland New Landmark Construction" and make new achievements.

This time, the assisting task of the SEMW?ultra-high pressure jet drilling rig is mainly to do water stop reinforcement work in the west area of ??the artificial intelligence town near the subway. The?SEMW?SMJ-120 equipment requires the water stop pile to be nearly 30m underground from the ground.

The entire water-stop project needs to be vertically built on three water-stop reinforcement walls from west to east. The first water-stop wall and the second and third sides are reinforcement walls. The total number of jet grouting piles is nearly 100, and the pile diameter is 2.4m. The difficulty of the project lies in the water-stopping piles. The subway tunnel near Zhumei Road Station of Line 15 is only about 1m away. In order to prevent excessive pressure inside the ground from causing soil compression and swelling to cause damage to the subway tunnel, during the construction process, the equipment ground pressure monitoring system and its own verticality And there are extremely high requirements, and the construction is very difficult.

SEMW?SMJ-120 crawler ultra-high pressure rotary jet drilling rig realizes horizontal, vertical, inclined and 360° omni-directional construction. The equipment has a small impact on the surrounding environment through internal pressure detection and forced mud discharge to monitor underground mud pressure in real time. It can greatly reduce the impact on the surrounding environment and perfectly solve the problem of short-distance construction of the project near the subway, which is highly praised by the project party.

SEMW?SMJ-120 crawler ultra-high pressure rotary jet drilling rig has more than "two brushes". The equipment can use high-pressure water, high-pressure air and high-pressure cement slurry to create a device through a unique perforated tube and front end. ,Use high-pressure jet cutting to destroy the surrounding soil, pressurize the hardened material slurry, spray, cut the ground, mix, discharge mud, mud collection, and mud transport a series of processes as the monitoring object. It can perform horizontal, vertical and inclined And 360° all-round foundation reinforcement construction equipment. The biggest feature of the equipment construction is to achieve forced mud discharge in the hole, and to control the internal pressure by adjusting the amount of mud discharged, effectively suppress the foundation uplift or settlement caused by jet mixing, and greatly reduce the impact on the environment. Proven strength in a number of projects!

SEMW?products have shown their talents in the "major projects" one by one in the market. SEMW services have been praised repeatedly in the "escort". The century-old SEMW?brand is well-known in a series of "difficult problems"! Hundred years of SEMW, craftsmanship, great beauty, China,SEMW"build" certificate!
