Rectangular pipe jacking construction method for long-distance full-section rock stratum condition
The invention discloses a rectangular pipe jacking construction method for a long-distance full-section rock stratum condition, and relates to the field of underground space construction of underground comprehensive pipe galleries, underground passages and the like. S1, construction operation of a starting well and a receiving well; s2, a normal tunneling area and an expanding excavation area are divided according to the size of the reserved tunnel portal, the operation area of the rectangular pipe jacking machine and the cutting area of the cutterhead, and advanced pre-tunneling is conducted on a rock stratum of the expanding excavation area through a miniature circular pipe jacking method; s3, starting construction operation of the rectangular pipe jacking machine; s4, normal tunneling construction operation of the rectangular pipe jacking machine; and S5, the rectangular pipe jacking machine receives the construction operation. The method overcomes the industrial and professional prejudice that rectangular pipe jacking construction is not suitable for rock stratum conditions with uniaxial compressive strength larger than 5 MPa, and overcomes the defects that horizontal directional drilling is low in processing precision, poor in effect, not suitable for long-distance rectangular pipe jacking, low in construction efficiency and high in cost in advanced pre-tunneling. And the method can be applied to long-distance full-section rock stratum construction more quickly, accurately, economically and reasonably.
一种用于长距离全断面岩石地层条件的矩形顶管施工方法，涉及地下综合管廊、地下通道等地下空间施工领域。S1：始发井、接收井施工作业；S2：依据预留洞门尺寸、矩形顶管机的运行区域和刀盘的切削区域划分正常掘进区和扩挖区，使用微型圆形顶管法对扩挖区的岩层进行超前预掘进；S3：矩形顶管机始发施工作业；S4：矩形顶管机正常掘进施工作业；S5：矩形顶管机接收施工作业。本发明克服了矩形顶管施工不宜适用于单轴抗压强度大于5MPa岩石地层条件的行业及专业偏见，解决水平定向钻进行超前预掘进中处理精度低效果差、不适用于长距离矩形顶管、施工效率慢、费用高的缺点，更加快速、精准、经济合理地应用长距离全断面岩层施工。
