中文The sudden new crown pneumonia epidemic has brought a serious impact to the global economy, and the construction machinery industry has been "battled". Shanggong Machinery has considered this and cancelled the plan for participating in the Bauma Exhibition and held a special product exhibition for Shanggong enterprises.
Strive for perfection, and be more exciting. The theme of this exhibition is "Hand in hand for a win-win future". Shanggong Machinery's full range of equipment: SMW construction equipment, TRD construction equipment, full-rotation drill construction equipment, CSM construction equipment, SDP static drilling root construction equipment, MJS construction equipment Equipment and various construction methods such as DCM, SCP, hammered piles, etc. all appeared on the stage, showing the leading technology and excellent quality of the whole series of Shanggong Machinery products to the outside world in an all-round and multi-level manner, which once again aroused the shock and attention of the industry and received the on-site industry Highly praised by leaders and VIP customers.
▲Shanggong Machinery 2020 enterprise special product exhibition site
Ace products debut shockingly, customer zero-distance experience
At the exhibition, Shanggong Machinery carried out on-site equipment demonstrations on TRD construction method machines, full-rotary tube drilling rigs, and MJS-120 crawler drilling rigs. The products all demonstrated Shanggong Machinery’s unique ingenuity in terms of performance, technological innovation and appearance. Incorporating innovative features to fully meet the needs of market customers.

▲TRD construction method machine equipment demonstration site
The scope of application of TRD method:
1. High equipment safety;
2. Form the cement-soil continuous wall with equal thickness and seamless overlap;
3. Form a uniform wall with equal strength and high quality in the depth direction;
4. High construction accuracy.
The scope of application of TRD method:
1. Temporary supporting anti-seepage walls, building basements, groundwater treatment system facilities, excavating tunnels, subway projects, etc.;
2. Permanent anti-seepage walls, reservoirs, dam reinforcement, anti-seepage, underground dams, industrial waste treatment facilities, etc.;
3. Other foundation improvements: Building foundations, dam foundation measures, port facilities, oil storage tanks, sinking prevention walls, etc.
▲Demonstration site of full-rotation full-pipe drilling rig equipment
Five construction methods of full-rotation full-pipe drilling rig:
1. High-precision and unbiased steel column insertion method
2. Construction method of occlusal pile continuous wall
3. Construction method of cast-in-place pile
4 Construction method for removing old piles (clearing obstacles)
5. Construction method of rotary drilling rig and full set of pipe drilling rig
The advantages of using a full-rotary full-pipe drilling rig for construction:
▲No noise, no vibration, high safety;
▲No mud is used, the working surface is clean, environmental protection is good, and the possibility of mud entering the concrete is avoided, the quality of the pile is high, which is beneficial to improve the concrete's binding force to the steel bar;
▲The formation and rock characteristics can be judged intuitively during construction drilling;
▲Drilling speed is fast, about 14m/hour for general soil layers;
▲Drilling depth is large, according to soil conditions, the maximum depth has reached 158m;
▲The verticality of the hole is easy to grasp, and the verticality can be accurate to 1/500;
▲No collapse of holes, high quality of holes;
▲The hole diameter is standard and the filling factor is small. Compared with other hole forming methods, it can save a lot of concrete consumption;
▲Clean the hole thoroughly, fast, and the bottom drilling slag can be cleaned to about 3.0cm.
▲MJS-120 crawler drilling rig equipment demonstration site
The SMJ-120 crawler drilling rig can be applied to the MJS construction method, that is, the omni-directional high-pressure jet construction method. Its principle is to use three media, high-pressure water, high-pressure air and high-pressure cement slurry, through a unique perforated pipe and a front-end creating device, with high-pressure jet Cutting and destroying the surrounding soil, the hardening material slurry pressure transportation, spraying, cutting the ground, mixing, mud discharge, mud collection, mud transportation a series of processes as the monitoring object, it is a kind of horizontal, vertical, inclined and 360° full Construction method of azimuth foundation reinforcement.
The main technical characteristics of SMJ-120 crawler drilling rig for MJS construction method:
1. All-round high-pressure grouting and jetting construction;
2. Large pile diameter and good pile quality;
3. Large reinforcement depth;
4. Less mud pollution;
5. Small impact on the surrounding environment.
During the exhibition, a signing ceremony was held on site, and the signing covers: TRD70E construction method machine, DTR2106 full-rotation casing drilling rig, SMW construction method equipment, H240 hydraulic piling hammer, pipe rubbing machine and other equipment and technical cooperation projects for the construction of integrated machines.
