High limit rotary excavation: what is the construction know-how of rotary drilling rig?

High limit rotary excavation: what is the construction know-how of rotary drilling rig?

Rotary excavators are also known as rotary drilling rigs and pile drivers. Rotary drilling rig is a kind of comprehensive roadheader, which has the characteristics of using multiple foundations, fast perforation speed, less pollution and high mobility. The short auger bit can be used for dry drilling, or wet drilling with a rotary bit in the case of mud protection. Rotary digging machine can be used with the hammer to dig hard strata, digging holes. The enlargement drill can enlarge the hole at the bottom of the hole. The drilling rig adopts multi-layer telescopic drilling rig, which has less auxiliary drilling time, low labor intensity, no mud circulation and discharge, and cost saving. It is especially suitable for urban construction infrastructure projects. So, high limit rotary excavation: what is the construction know-how of rotary drilling rig?

What is high-limit rotary excavation? What is the use of high-limit rotary excavation?

The limited height rotary excavation is a kind of mechanical equipment for the construction of cast-in-place pile by taking soil and forming holes. The rotary bucket is driven by the drill rod to rotate and cut the earth, and then lifted to the outside of the hole for regular dredging. The rotary drilling rig adopts a multi-purpose modular design and can be used for the construction of various piles. More convenient than previous pile drivers.

Low headroom rotary excavation rental manufacturers share matters needing attention in rotary excavation construction in different strata

Therefore, when the geotechnical construction unit undertakes the bored pile foundation engineering, the pile foundation drilling is faced with no small uncertainty. In the process of pile foundation drilling, if some technical problems are not handled properly, it will not only increase economic losses, but also pose a threat to the safety of engineering equipment and personnel. Below low headroom rotary excavation rental manufacturers share the considerations for rotary excavation construction in different formations.

TYSIM Foundation KR125A Jiangyin Housing Construction Project Outstanding Performance

TYSIM Foundation KR125A Jiangyin Housing Construction Project Outstanding Performance

Recently, TYSIM Foundation KR125A Small Rotary Drilling Rig was constructed in the 2020C-39 Plot Development Project of Jiangyin Yi Shan Lake Chengli Land, a commercial housing in Jiangyin City, Jiangsu Province. The project is a commercial housing construction project. The geological conditions of the site are mainly backfilled stratum, muddy silty clay, silty clay mixed with silty soil, silty sand and silty clay, which is difficult to construct. The stratum is formed by backfilling the original lake, especially the muddy silty clay stratum is prone to collapse. The on-site bored pile diameter is 600mm and 800mm, the hole depth is 11m ~ 20m, the 11m casing wall protection is used under the puller, and the rotary drilling rig successfully completes the hole-forming construction. TYSIM foundation is equipped with skilled operators for more than 3 years. It is necessary to strictly control the drilling speed and drill pipe lifting speed, effectively prevent hole collapse, give full play to the advantages of small drilling rig and large power, successfully complete the construction task, reduce the construction cost for customers, shorten the construction period, and win the unanimous praise of customers.
