▲Project site

Last December, Shanghai's Xuhui District officially released the "T Plan" for building a new AI highland. Among them, two strategic carriers stand out, especially the Beiyang AI Town project. As a project aimed at building a new landmark and core area for Shanghai's national AI highland, AI has achieved a new leap "from nothing to something" and "from something to excellence," which is of great significance for creating an AI sci-tech innovation system in the future.

Project Introduction

The project is located within the outer ring in Huajing Town, Xuhui District, adjacent to the under-construction Zhumei Road Station of Metro Line 15. It lies in the "Caohejing-Minhang Zizhu" national-level sci-tech innovation belt and is a key area for industrial restructuring and upgrading in Xuhui District in recent years. The town extends east to Changhua Road, south to the Outer Ring Road, west to Old Humin Road, and north to Dianpu River. The planned total land area is about 54.3 hectares, with a total construction area of about 740,000 square meters, including about 600,000 square meters for scientific research, about 96,000 square meters for rental housing, and about 44,000 square meters for service facilities.

Ultra-High Pressure Jet Grouting Rig Deployed, Achieving New Success

In mid-August, after the Shanggong SMJ-120 ultra-high pressure jet grouting rig appeared at the "Shanghai Tower East District New Construction Project" and successfully solved construction challenges, it has now entered the site of the "Caohejing Beiyang AI Town" project in Xuhui District in the form of an engineering relay battle. With its powerful product strength, it helps accelerate the "construction of a new landmark for the AI highland" and achieves new success.

▲Equipment construction site

This time, the main task of the Shanggong ultra-high pressure jet grouting rig is to perform water-stop reinforcement operations near the subway in the western district of AI Town. The Shanggong SMJ-120 equipment needs to install water-stop piles from the ground to nearly 30 m underground.

The entire water-stop project requires three vertical water-stop reinforcement walls from west to east. The first is a water-stop wall, and the second and third are reinforcement walls. There are nearly more than 100 jet grouting piles in total, with a pile diameter of 2.4 m. The engineering difficulty lies in the fact that the water-stop pile body is only about 1 m away from the underground tunnel of Zhumei Road Station on Metro Line 15. To prevent excessive underground pressure from causing soil squeezing and heaving that could damage the subway tunnel, the construction process places extremely high requirements on the equipment's ground pressure monitoring system and its own verticality, making construction very difficult.

▲Construction near the subway station

The Shanggong SMJ-120 crawler-type ultra-high pressure jet grouting rig can perform horizontal, vertical, inclined, and 360° all-directional construction. With minimal impact on the surrounding environment, the equipment monitors underground slurry pressure in real time through ground pressure detection and forced slurry discharge, greatly reducing the impact on the surrounding environment and perfectly solving the challenge of construction at close range near the subway, earning high praise from the project owner.

▲Equipment construction site

The Shanggong MJ-120 crawler-type ultra-high pressure jet grouting rig's skills for achieving new success are not limited to just "a couple of tricks." The equipment can use three media—high-pressure water, high-pressure air, and high-pressure cement slurry—to cut and break surrounding soil through a unique multi-hole pipe and front-end forming device. It treats a series of processes—pressurized delivery of hardening material slurry, jetting, cutting the stratum, mixing, slurry discharge, slurry collection, and slurry transport—as monitoring objects. It is a construction device capable of horizontal, vertical, inclined, and 360° all-directional foundation reinforcement. The most notable feature of this equipment's construction is the realization of forced slurry discharge in the hole and control of underground pressure by adjusting the slurry discharge volume, effectively suppressing foundation heaving or settlement caused by jet mixing and greatly reducing environmental impact. It has now been verified by strength in multiple projects!

Shanggong products have distinguished themselves in one "major project" after another in the market. Shanggong services have been widely praised in one "escort" after another. The century-old Shanggong brand has become widely known through one "problem solved" after another! Century-old Shanggong, crafted with ingenuity; beautiful China, witnessed by Shanggong!
