近日，土耳其伊斯坦布尔某四星酒店扩建项目桩基工程正式启动，江苏泰信机械股份有限公司（以下简称“泰信机械”）自主研发的KR360M卡特彼勒底盘多功能旋挖钻机，凭借对复杂地层的适配能力成为项目核心施工设备。该项目需完成直径0.8m、有效桩深14m的钻孔灌注桩，施工区域面临溶洞与大鹅卵石地层挑战。

Recently, the pile foundation project for the expansion of a four-star hotel in Istanbul, Turkey has officially kicked off. The KR360M multi-functional rotary drilling rig with a Caterpillar chassis, independently developed by TYSIM Piling Equipment Co., Ltd. (hereinafter referred to as "TYSIM"), has become the core construction equipment for the project thanks to its adaptability to complex strata. The project requires the construction of cast-in-place bored piles with a diameter of 0.8m and an effective pile depth of 14m, while the construction area faces challenges from karst caves and large cobblestone formations.

工艺突破：全护筒+卡特底盘破解地质痛点​

Process Breakthrough: Full Casing + Caterpillar Chassis Addresses Geological Pain Points

针对项目地质特性。KR360M采用“全护筒跟管钻进”的核心方案，结合设备自身配置实现高效成孔。首先，卡特底盘保障稳定作业---设备搭载适配的卡特彼勒OEM旋挖定制底盘，具备强劲扭矩与整机重量优势，在大鹅卵石层钻进时可有效抑制机身晃动，确保护筒下放垂直度，避免因底盘不稳导致的护筒偏斜。其次，全护筒工艺隔绝风险---采用与直径0.8m桩径匹配的护筒（预留合理间隙以保障混凝土灌注），钻进时同步跟进护筒至溶洞底以下，直接隔绝溶洞段松散土层，解决塌孔问题。遇到大鹅卵石层时，通过 “筒钻破碎 + 捞砂斗清渣” 组合作业。最后，效率达标且质量可控---经现场施工验证，KR360M在该地质条件下，单桩从护筒下放、钻进清渣到成孔验收，全程可控在6小时以内，且桩身完整性均符合设计要求。​

Targeting the project's geological characteristics, the KR360M adopts the core solution of "full casing follow-drilling" and achieves efficient hole formation through its own configuration. First, the Caterpillar chassis ensures stable operation – the equipment is equipped with an adapted Caterpillar OEM custom rotary drilling chassis, boasting strong torque and overall machine weight advantages. When drilling in large cobblestone formations, it can effectively suppress machine vibration, ensure the verticality of casing lowering, and avoid casing deviation caused by unstable chassis. Secondly, the full casing process isolates risks – a casing matching the 0.8m pile diameter is used (with a reasonable gap reserved to ensure concrete pouring). During drilling, the casing is synchronously advanced below the bottom of karst caves, directly isolating the loose soil layer in the karst cave section and solving the hole collapse problem. When encountering large cobblestone formations, a combined operation of "cylinder drill crushing + sand bucket slag cleaning" is adopted. Finally, efficiency meets standards and quality is controllable – verified by on-site construction, under such geological conditions, the entire process of a single pile from casing lowering, drilling and slag cleaning to hole formation acceptance can be controlled within 6 hours, and the pile integrity all meets the design requirements.

钻进施工效率高： 定制工艺+卡特服务成施工关键

High Drilling Efficiency: Customized Processes + Caterpillar Services Are Key to Construction

“相比之前使用的设备，KR360M在两种复杂地层的切换作业中表现更稳定。” 项目施工团队负责人表示，全护筒工艺的应用大幅降低了返工率，且卡特底盘钻机的耐用性与稳定性，让设备日均作业时长可达16小时以上，有效保障了工期推进。同时，泰信机械提供的施工工艺指导，针对现场地质变化及时调整钻进参数，进一步提升了施工效率。作为泰信机械面向中大型旋挖市场的主力产品，KR360M其核心优势在于可根据不同地质（如溶洞、卵石、砂层、硬岩）定制钻进方案，搭配全护筒、泥浆护壁等多种工艺，且依托卡特彼勒国际知名品牌底盘的全球服务网络，能快速响应海外项目的售后需求，成为不少国际工程选择泰信旋挖的重要选项。​

"Compared with the equipment used previously, the KR360M performs more stably when switching operations between the two complex strata," noted the leader of the project construction team. The application of the full casing process has significantly reduced the rework rate, while the durability and stability of the Caterpillar-chassis rig enable the equipment to operate for over 16 hours per day on average, effectively guaranteeing the project schedule. Meanwhile, TYSIM provides construction process guidance, timely adjusting drilling parameters in response to on-site geological changes to further improve construction efficiency. As TYSIM's flagship product for the medium and large-sized rotary drilling market, the KR360M's core advantage lies in its ability to customize drilling solutions for different geological conditions (such as karst caves, cobblestones, sand layers, and hard rock), combined with various processes including full casing and mud wall protection. Additionally, leveraging the global service network of the internationally renowned Caterpillar chassis, it can quickly respond to after-sales needs of overseas projects—becoming a key factor for many international projects to choose TYSIM rotary drilling rigs.

此次泰信机械研制的KR360M卡特彼勒底盘多功能旋挖钻机在伊斯坦布尔项目的应用，进一步验证了设备对“溶洞 + 卵石”复合地层的应对能力。未来将继续围绕全球不同区域的地质特点，优化设备与施工工艺的适配性，比如针对中东、欧洲等地区常见的复杂地层，推出更精准的“设备选型+工艺指导”一体化服务，助力海外项目高效施工，同时持续完善全球销售与服务网络，提升中国桩工装备在国际市场的认可度。​

The application of the KR360M multi-functional rotary drilling rig with a Caterpillar chassis, developed by TYSIM, in the Istanbul project has further verified the equipment’s capability to handle the "karst cave + cobblestone" complex composite strata. In the future, TYSIM will continue to focus on the geological characteristics of different global regions to optimize the adaptability between equipment and construction processes. For instance, targeting complex strata common in regions like the Middle East and Europe, it will launch more precise integrated services of "equipment selection + process guidance" to support the efficient construction of overseas projects. Meanwhile, TYSIM will continuously improve its global sales and service network, enhancing the international market recognition of Chinese pile foundation equipment.
