Description
一种 "履带式"液压组合支架临时支护与永久支护平行作业掘进工艺及设备 技术领域 Parallel operation and equipment for parallel operation and temporary support of "crawler type" hydraulic combined bracket
本发明涉及一种地下工程安全高效快速施工的巷道支护工艺及配套设备。 The invention relates to a roadway supporting technology and ancillary equipment for safe, efficient and rapid construction of underground engineering.
背景技术 Background technique
地下工程综合机械化掘进施工工艺， 因其安全可靠、 单进效率远高于传统的炮掘工艺， 目前已被广泛推广应用。 综合机械化掘进施工工艺一个循环的主要耗时在于掘进机截割和巷 道支护。 如何实现掘进机截割与巷道支护平行作业， 自上个世纪五十年代至今， 国内外采矿 界进行了大量的探索， 并产生了很多技术与装备。 其中主要的技术点涉及两个方面， 即快速 实施安全可靠的临时支护和掘进机截割与永久支护的平行作业。 The comprehensive mechanized excavation construction technology of underground engineering has been widely promoted and applied because of its safety and reliability, and the single-entry efficiency is much higher than the traditional artillery excavation process. The main time-consuming time for a comprehensive mechanized tunneling construction process is the roadheader cutting and roadway support. How to realize the parallel operation of roadheader cutting and roadway support. Since the 1950s, the mining industry at home and abroad has carried out a lot of exploration and produced a lot of technology and equipment. The main technical points involve two aspects, namely the rapid implementation of safe and reliable temporary support and the parallel operation of the cutting machine cutting and permanent support.
临时支护是为防止巷道开掘后围岩冒落坍塌伤人， 为保证永久支护作业人员的安全而设 的， 对于开采深度较浅且围岩强度高、 开挖后自支撑稳定可靠、 地质构造简单等适合条件， 可以不作临时支护， 直接进行永久支护， 一般情况下的巷道施工在巷道开挖后要先在掘进迎 头附近实施临时支护， 在临时支护的保护下实施巷道的永久支护。 Temporary support is to prevent the surrounding rock from falling and collapsing after the tunnel is excavated. In order to ensure the safety of the permanent support workers, the mining depth is shallow and the surrounding rock strength is high, and the self-supporting after excavation is stable and reliable. Simple construction and other suitable conditions, can be used for temporary support without temporary support. Under normal circumstances, after roadway excavation, temporary support should be carried out near the heading of the roadway, and the roadway should be implemented under the protection of temporary support. Permanent support.
现有掘进巷道临时支护方式主要有 6种类型： There are six main types of temporary support methods for excavation roadways:
1、 传统的临时支护方式有吊环加钢管 （或轨道、 型钢） 等， 通过前窜钢管 （或轨道、 型 钢） 等再加护顶材料临时支护顶板。 1. The traditional temporary support method includes a lifting ring and a steel pipe (or rail, steel), etc., and the top plate is temporarily supported by a front-end steel pipe (or rail, steel).
2、 掘进机机架式托梁护顶方式。 2. The boring machine rack-type joist top protection method.
3、 掘锚一体化掘进机。 3. Digging and anchoring integrated roadheader.
4、 前后推拉式或成对交替迈步式液压自移支架。 4. Push-pull or pair-wise alternating step-by-step hydraulic self-moving brackets.
5、 德国研制的单轨吊架棚机。 5. The monorail hanger room machine developed by Germany.
6、 TBS遂道施工掘进机临时支护形式。 6, TBS ramp construction roadheader temporary support form.
现有临时支护存在的主要问题： The main problems with existing temporary support:
1、 传统的临时支护前窜时需人工铺网、 上接顶材料， 劳动强度大， 空顶下作业不安全， 对顶板支护力几乎没有，只能对作业人员起到有限的保护作用，常出现现场作业人员图省事、 怕麻烦、 不使用现象。 1. In the case of traditional temporary support, manual laying and topping materials are required. The labor intensity is high, the operation under the empty roof is unsafe, and there is almost no support for the roof. It can only provide limited protection for the workers. It is often the case that the on-site operators have troubles, are afraid of trouble, and are not using the phenomenon.
2、 掘进机机架托梁式临时支护， 铺网作业仍在空顶下， 支护面积达不到全断面， 机架强 度及与掘进机连接强度受限， 支护力很小， 实施临时支护及永久支护时掘进机就无法平行作 业。 2. The temporary support of the boring machine frame joist type, the laying operation is still under the empty roof, the supporting area can not reach the full section, the strength of the frame and the connection strength with the roadheader are limited, the supporting force is small, and the implementation When the temporary support and permanent support are used, the roadheader cannot work in parallel.
3、 掘锚一体化掘进机。 从六十年代第一代掘锚机诞生至今已进行过两次变革， 第三代掘 锚一体化， 虽然实现了掘锚平行作业， 但锚杆空顶距大， 一般在 1.2-1.5米以上， 支护不能紧 跟迎头， 所以， 仅适用于釆深不大、矿压小、 围岩条件较好的大断面矩形或梯形巷道， 因此，
一直没有得到广泛的推广应用。 像我国绝大部分矿区及德国、 波兰等国家开釆深度较深， 矿 压大， 围岩松软破碎等条件， 锚杆密集， 甚至还需要掛网、 锚索支护， 支护工作量大， 不仅 空顶距离满足不了要求， 支护时间远大于截割时间， 也很难与截割同步。 3. Digging and anchoring integrated roadheader. Since the birth of the first generation of the anchoring machine in the 1960s, two changes have been made. The third generation of integrated anchoring and anchoring, although the parallel operation of the anchoring and anchoring is realized, the anchoring of the anchor is large, generally above 1.2-1.5 meters. The support can't keep up with the head. Therefore, it is only suitable for large-section rectangular or trapezoidal roadways with small depth, small mine pressure and good surrounding rock conditions. Therefore, Has not been widely promoted and applied. For example, most of China's mining areas and Germany, Poland and other countries have deeper depths, large mine pressures, soft and broken surrounding rocks, and dense anchors. Not only can the empty top distance not meet the requirements, but the support time is much longer than the cutting time, and it is difficult to synchronize with the cutting.
4、 前后推拉式或成对交替迈步式液压自移支架， 每一个循环对顶板反复支撑一次， 易破 坏顶板， 不利于对顶板的支护， 顶板条件不好时， 必须停机支护， 不能实现掘进机截割与永 久支护平行作业。 4. Push-pull type or front-to-back alternating step-type hydraulic self-moving brackets. Each cycle repeatedly supports the top plate once, which is easy to damage the top plate. It is not conducive to the support of the top plate. When the roof condition is not good, it must be stopped and supported. The roadheader cuts in parallel with the permanent support.
5、 德国研制的单轨吊架棚机。 可以实现永久支护的机械化操作， 避免人员进入无支护区 作业， 但该设备结构太复杂， 外形尺寸大， 只能适用于大断面巷道施工， 支护与掘进截割在 同一区域， 相互干挠， 影响平行作业效率。 5. The monorail hanger room machine developed by Germany. The mechanized operation of permanent support can be realized to prevent personnel from entering the unsupported area. However, the structure of the equipment is too complicated and the external dimensions are large. It can only be applied to the construction of large-section roadways. The support and excavation are cut in the same area, and they are mutually dry. Scratching, affecting the efficiency of parallel operations.
6、 TBM岩石掘进机有敝开式、 双护盾、 单护盾等， 遂道施工临时支护形式是与全断面 截割掘进机一体化的支护方式。 该支护方式掘进迎头对顶帮的支护是通过护盾全长对围岩的 整体支撑、 收缩、 前移、再支撑， 反复支撑易破坏围岩， 仅适用于拐弯曲率半径大、 大断面、 围岩条件较好的遂道施工， 遇断层、 破碎带易被卡住。 6. The TBM rock boring machine has split type, double shield, single shield, etc. The temporary support form of the tunnel construction is the support method integrated with the full section cutting and boring machine. The support method is used to support the head support. The overall support, contraction, forward movement and re-support of the surrounding rock through the full length of the shield, and repeated support for the damage of the surrounding rock, only applicable to the large bending radius and large section. The construction of the ramp with better surrounding rock conditions is easy to get stuck in the fault and the broken belt.
针对上述问题， 本发明公布了一种 "履带式" 临时支护与永久支护平行作业掘进工艺及 设备。 In view of the above problems, the present invention discloses a "crawler type" temporary support and permanent support parallel operation excavation process and equipment.
