Description

基于探地雷达的盾构施工系统 Shield construction system based on ground penetrating radar

技术领域 FIELD

[0001] 本发明涉及一种盾构施工系统,尤其涉及一种基于探地雷达的盾构施工系统。 [0001] The present invention relates to a shield construction system, in particular, it relates to a shield tunneling system based GPR. 背景技术 Background technique

[0002] 盾构施工前方情况复杂多变,常常存在不良地质因素和未知埋藏物,如市政管道、人工构建物、水泡、气泡、碎石、沉船等。 [0002] where the front shield construction complicated, and there is often poor geological factors unknown buried objects, such as municipal pipes, artificial constructs, blisters, bubbles, gravel, wreck like. 这些因素会造成工作面塌方、涌水,轻则影响隧道的掘进速度,延误工期,增加施工成本;重则造成设备损坏和人员伤亡,后果不堪设想。 These factors can cause landslides face, gushing, ranging from the impact of tunnel driving speed, delay the construction period, increase the construction cost; while in causing damage and casualties, the consequences could be disastrous. 所以,需要对盾构工作面前方的地质状况进行超前探测和辨识,为施工提供较准确的资料,指导盾构挖掘,规避风险。 Therefore, the need for geological conditions Shield in front of party work were advanced detection and identification, provide more accurate information for construction, mining guide shield, to avoid risks.

[0003] 工程中获得盾构施工前方地质情况的主要方法是地质钻孔法,近年来,随着技术的发展和应用,还出现了如隧道地震波超前预报(Tunnel Seismic I^rediction)、水平声波剖面法(HSP)、地电阻影像探测等方法。 The main method [0003] obtained Shield Construction Engineering geological conditions in front of geological drilling method, in recent years, with the development and application of technology, there was seismic advanced prediction (Tunnel Seismic I ^ rediction) such as tunnels, level of sonic profile method (HSP), to the image detecting resistor or the like.

[0004] 探地雷达是一种可进行无损检测的高科技产品,将其安装到盾构机刀盘上用以对前方地质进行探测实属创新性运用,但是,若要实现探地雷达和盾构机的协调配合,保障盾构施工的顺利进行,则还需考虑到如下因素: [0004] GPR is a non-destructive inspection can be high-tech products, which is mounted on the cutter shield machine to the front of it is the innovative use for geological exploration, however, to achieve the GPR and coordination with the shield machine to ensure the smooth progress of the construction of the shield, we also need to take into account the following factors:

[0005] 首先,盾构机在地下工作环境恶劣,而雷达是一种精密度非常高的电子元器件,防水等级低,只能承受较低的压力,为了保护雷达正常工作及不受外界条件损害,则必须对盾构刀盘进行改造。 [0005] First, the bad shield underground work environment, and radar is a very high precision electronic components, low water level, can only withstand low pressure, in order to protect the radar and without outside normal working condition damage, it must be modified to shield the cutter.

[0006] 再者,由于探地雷达天线及DAD控制器安装在盾构机头部刀盘上并随刀盘一起转动,而雷达获得的地质信息需传送至盾构尾部的控制室内才能在计算机上处理并显示,信号传输距离较远,并且盾构机内存在很多金属干扰,若全程通过无线传输方式必然出现信号不稳定等弊端,所以单独采用无线传输方式不能满足要求。 [0006] Further, since the GPR antenna is mounted on a controller and DAD shield machine cutter head and rotates together with the cutter, the geological information obtained by the radar needs to be transmitted to the control room computer to shield tail the processing and display, the signal transmission distance, and a lot of memory metal shield machine interference, signal instability and other drawbacks inevitable if the entire wireless transmission manner, so that the wireless transmission alone can not meet the requirements. 同时,因刀盘相对于盾尾控制室是旋转的,若全程采用有线传输方式又会产生绕线问题,所以单独采用有线传输方式也不适合。 Meanwhile, because the shield tail cutter with respect to the control chamber is rotating, if the full use of the winding cable transmission problems will be produced, so that alone is not suitable for cable transmission. 这就需要解决信息的传输问题。 This requires solving the problem of information transmission.

[0007] 其外,目前采用的探地雷达为意大利IDS公司生产的K2型探地雷达,该雷达采用蓄电池供电,电压12伏,其优点是电压和电流波动范围小,能保证雷达的精确运行及其信号的无失真传输,缺点是持续供电能力不够,连续供电几十小时后需要充电才能继续使用。 [0007] Besides, the currently used GPR Italy IDS produced K2 GPR, the radar uses battery power, 12 volts, which is the advantage of a small voltage and current fluctuation range, to ensure accurate operation of the radar distortion-free transmission of its signal, the disadvantage is continuous power supply capacity is not enough, after several hours of continuous power supply needs to be charged to continue. 由于盾构机在地下施工时间较长,有时达到半年左右,期间不可能对电池进行充电,并且地下环境很潮湿,不适合电池工作,所以采用蓄电池供电方式并不适合。 Since the construction of the ground shield machine long in time, sometimes reaches about half a year, during charging of the battery is impossible, and very humid subterranean environment, is not suitable for battery operation, it is not suitable for using battery power supply. 为此专门设计了一套直流供电系统。 Specially designed as a DC power supply system. 该直流供电系统可将施工现场220伏的交流电转化为12伏的直流电。 DC power supply system of the construction site may be converted to 220 volts AC 12 volts DC. 但是,如果采用电线传输电力,在盾构机中心回转接头部分也会产生绕线问题。 However, if the power transmission wires, the swivel joint part center shield machine winding will produce problems. 所以,还需解决将直流供电系统提供的12伏直流电由盾构尾部传到盾构的头部这一难题。 Therefore, the need to resolve the 12 VDC DC power supply system provided by this problem spread to shield the head from the shield tail.

具体实施方式 Detailed ways

[0041] 本实施例的盾构施工系统包括盾构机以及主要由雷达天线和与之连接的DAD控制器构成的雷达。 [0041] Construction of the shield system of the present embodiment comprises a shield machine by the radar and radar antenna and mainly DAD configuration of a controller connected thereto. 以下详细说明该盾构施工系统的结构。 The structure of the shield construction system described in detail below.

[0042] 本实施例选用意大利IDS公司的RIS-K2型雷达配备200MHz天线,该雷达天线尺寸,其长度a为420mm,宽度b为360mm,高度c为170mm。 [0042] Example embodiment of the present IDS selected Italian company RIS-K2 200MHz equipped with radar antennas, the size of the radar antenna, which is a length of 420mm, width b is 360mm, the height c is 170mm. 雷达体积小、重量轻,配备多通道雷达数据采集单元,主要由DAD控制单元、雷达天线、计算机、网络电缆、电源电缆、蓄电池等部分组成。 Radar small size, light weight, with a multi-channel radar data acquisition unit, a main unit, a radar antenna, a computer, a network cable, power cable, batteries and other portions of the DAD controlling the composition. 具体性能指标如下。 Specific performance indicators are as follows.

[0043] 电性指标:12V直流电源;电压范围为13. 5〜13. 8V。 [0043] The electrically index: 12V DC power supply; voltage range 13. 5~13 8V..

[0044] 环境指标:工作温度-10〜+40°C ;相对湿度< 90% ;防水、防尘、防暴标准达到了IP65。 [0044] Environmental Specifications: Operating temperature -10~ + 40 ° C; relative humidity of <90%; waterproof, dustproof, riot reached the standard IP65.

[0045] 如图1所示,通常盾构机整体可大致分成三个部分:切口环、支撑环和盾尾。 [0045] As shown in FIG. 1, the entire shield machine can generally be roughly divided into three parts: the notch ring, the support ring and the shield tail. 刀盘位于切口环的前方,并作旋转运动。 In front of the cutter cut loops, and rotational movement. 支撑环和盾尾不作旋转,只是沿着隧道向前移动。 Support ring and the shield tail is not rotating, but moves forward along the tunnel. 在刀盘中心和支撑环之间即在切口环内中心存在中心回转体,中心回转体是用于向盾构前方输送水、液压油以及润滑油的关键部件,包括固定体、回转体、水管接头等。 I.e. the central ring present in the notch between the cutter and the center of the support ring rotation center thereof, the center of the rotary body is used for conveying water, hydraulic oils and lubricating oils key forward shield member, comprises a fixed body, rotating body, water and other joints.

[0046] 如图2〜北所示,雷达天线1必须安装在盾构最前方才能实现前向探测,通过对各种类型盾构机的调研,选择将天线1安装在盾构刀盘3上。 [0046] FIG. 2 ~ north, the radar antenna 1 must be installed prior to the forefront of the shield to achieve the detection, by various types of research shield machine selects antenna 1 is mounted on the cutter shield 3 . 在施工过程中,盾构刀盘不仅要受到来自掌子面的土压和水压,还要承受来自土仓的压力,盾构刀盘材料一般采用高强度低碳合金钢。 During construction, the cutter shield to be earth pressure not only from the working face and the pressure, but also under pressure from the earth magazine, the cutter shield made of high strength materials typically low carbon alloy steel. 雷达保护板5处于盾构最前方,与刀盘3—起接触前方地层。 The radar protection shield plate 5 is in the forefront, with the cutter from contacting front 3- formation. 以法国FCB(Fives Cail Babcock) 土压平衡盾构为例,在盾构施工状态下,盾构刀盘掌子面所承受的平均压力约为0. 5Mpa,遇到特殊地质时,所承受的压力可能瞬间升高。 When the French FCB (Fives Cail Babcock) EPB shield, for example, in the state shield construction, the average pressure of the working face shield cutter to bear about 0. 5Mpa, special geological encounter, the bear instant pressure may rise. 因此保护板材料既要有很好的强度、硬度、耐磨性、抗冲击性,又要具有很好的电磁穿透性。 Thus the protective plate materials have both good strength, hardness, wear resistance, impact resistance, but also has good electromagnetic penetration. 经过理论分析及多种材料的综合比较,选择具有良好机械性能、耐磨性能和电性能的聚四氟乙烯材料作为保护板材料。 Comprehensive theoretical analysis and comparison of a variety of materials, selected to have good mechanical properties, wear resistance and electrical properties of the protective plate made of Teflon material.

[0047] 雷达是一种精密度非常高的电子元器件,防水等级低,只能承受较低的压力,为了保护雷达正常工作及不受外界条件损害,需要对盾构刀盘进行机械改造。 [0047] radar is a very high precision electronic components, low water level, can only withstand a lower pressure, in order to protect the radar work and damage from external conditions, it is necessary to shield the cutter mechanical transformation. 在不影响刀盘强度、性能的前提下,在刀盘3上开挖雷达天线1大小的空间用于安装放置保护盒23,将天线1固定其中,表面覆以强度高、耐磨性好、电磁波穿透性能强的保护板5进行保护,并保持刀盘3完整。 Without affecting the strength of the disc cutter, performance, excavation radar antenna 31 to the deck size of space for the installation is placed a protective case 23, wherein the antenna 1 is fixed, the surface covered with high strength, good wear resistance, strong electromagnetic wave penetration performance to protect the shield plate 5, and the cutter holder 3 complete. 开挖的矩形孔洞中心距离刀盘中心2. 21米,矩形孔洞沿刀盘半径方向为0. 59米,沿圆周方向为0. 61米。 Excavation rectangular hole cutter center-center distance 2.21 m, the rectangular hole along the radial direction of the cutter is 0.59 meters, in the circumferential direction is 0.61 m. 整个雷达保护盒23采用螺栓55联接固定在安装基板52上,共使用16个螺栓55,均布,保护盒四边每边布置四个。 Radar entire protective case 23 is coupled with bolts 55 fixed to the mounting substrate 52, using a total of 16 bolts 55, uniform, protective case four quadrilateral arranged on each side. 雷达保护板5安装在安装基板52上,采用螺钉M固定。 The radar protection plate 5 is mounted on the mounting substrate 52 is fixed with screw M. 具体安装如下:将中央开设窗口结构的安装基板52首先焊接在盾构机刀盘3矩形孔洞4内,从而提供安装基础。 Specific installation as follows: the mounting substrate 52 defines the center of the first window structure 4, so as to provide a rectangular mounting hole in the base weld 3 cutter shield machine. 然后将保护板压板51压在保护板5上,通过螺钉M将压板51和保护板5 —并固定在基板52上。 Then, the protecting sheet pressing plate 51 is pressed on the protective plate 5, the pressure plate 51 by screws M and the protective plate 5 - 52 and fixed to the substrate. 最后通过螺栓55将保护盒23安装到基板52上。 Finally, the protective case 55 is mounted to the base plate 23 by bolts 52. 为了保证整个安装结构的密封生,在保护盒23与安装基板52之间以及保护板5与安装基板52之间分别设有密封圈53。 In order to ensure the seal mounting structure of the whole green, the protective cartridge 23 between the mounting substrate 52 and a protective plate 52 and the mounting substrate 5 is provided with sealing ring 53, respectively.

[0050] 为了保障雷达正常工作不受损坏,雷达天线1、DAD控制器2和无线AP8置于与雷达天线形状大小相适应的保护盒23中并固定,在盾构前方刀盘部分进行必要的机械改造,开挖出形状大小与保护盒匹配的孔洞4,保护盒23置于孔洞4内,并覆盖保护板5以保持刀盘完整。 [0050] In order to protect against damage to work radar, radar antenna 1, DAD AP8 wireless controller 2 and placed in a protective case and adapted to the shape and size of the radar antenna 23 and fixed, the necessary portion in the front of the disk cutter shield mechanical modifications, the shape and size excavated hole 4 matching protective case, the protective case 23 is placed within bore 4, and the protective cover plate 5 to complete the cutter holder. 同时,在盾构机前后方作必要的布线。 Meanwhile, in the front and rear shield machine to make the necessary wiring. 刀盘部分布线情况:位于保护盒内的DAD控制器2和无线AP8通过双绞线16连接,长度为0. 3米;无线AP8和延长天线7通过同轴电缆6连接,长度为5米。 Where the cutter portion of the wiring: DAD a protective box 2 and the wireless controller 16 is connected via twisted pair AP8, a length of 0.3 m; and a wireless AP8 extended antenna 7 connected through a coaxial cable 6, a length of 5 meters. 该同轴电缆6沿刀盘切口环相交处引线四分之一圆周,与水管同线路至中心回转体水管接头处打孔进入中心回转体后接在无线AP8延长天线7上。 The coaxial cable cutter 6 along the intersection of the notch ring leads quadrant, with the same water line to the central joint of the rotors into the central pipe perforating contact with the rotary body after the wireless 7 AP8 extended antenna. 人行闸至控制室的布线:位于中心回转体附近的无线路由的延长天线7通过同轴电缆6与位于盾构尾部的无线路由9连接,连接长度18. 6米;将无线路由9与控制室计算机10通过双绞线16连接,连接长度8. 6米。 Pedestrian gate wiring to the control room: wireless router located near the center of the rotary member 7 is connected to the extended antenna is located in the tail shield wireless router 9 by a coaxial cable 6, the connector length 18.6 m; the wireless router and the control chamber 9 The computer 10 is connected via twisted pair 16, a length of 8.6 m is connected. 由此,探地雷达获取盾构掌子面前方地质情况后,经由构建的数据传输系统传输到盾尾控制室,经过后续数据处理,在显示器上显示,用于指导盾构施工。 Accordingly, the GPR acquired geological conditions in front working face shield, transmitted via a data transmission system is constructed to shield the end of the control chamber, through the subsequent data processing, displayed on a display to guide shield construction.

[0051] IDS公司生产的K2型探地雷达采用的是蓄电池供电的模式,蓄电池供电的优点是电压和电流波动范围小,能保证雷达及其DAD控制器的精确运行及其信号的无失真传输。 [0051] IDS K2 produced using GPR is battery-powered mode, the advantage is a small battery-powered voltage and current fluctuation range, to ensure accurate and distortion-free transmission of the radar signal and the operation of the controller DAD . 但是根据盾构机的实际工作环境,采用蓄电池供电方式并不适合(不方便定期充电),为此本系统采用直流供电模式。 However, according to the actual working environment of the shield machine, not suitable for using battery power supply (not convenient periodic charging), DC power supply for this mode of the present system. 探地雷达工作电压和无线发射模块采用的是同样的12V直流电,而无线接受模块则采用的是9V的直流电。 GPR module operating voltage and the wireless transmitter uses the same 12V DC, and the wireless receiving module is used in the DC 9V. 从盾构的实际工作环境可知,无线接收模块可以采用其自带的交直流变压器供电,而对于探地雷达和无线发射模块来说,由于目前国内电压还并不是特别稳定,因此本系统设计了一套直流供电系统为探地雷达供电,并且本套供电系统还能对供电情况进行监控。 Shield from the actual working environment can be seen, the wireless receiver module can use its own AC-DC transformer power supply, and for the ground penetrating radar and a wireless transmitter module, since domestic voltage is also not particularly stable, and therefore this system design a DC power supply system GPR, and this set of power supply system can monitor the situation. 直流供电系统采用质量更轻,安装更加简便的高频电压器,并且附带有滤波器来滤除因电压不稳定而产生的噪音。 DC power supply system is lighter, easier to install the high-frequency voltage, and attached with a filter to filter out noise generated due to unstable voltage. 直流供电系统电路,选用了ST公司所生产的型号为ST6200C的IC作为供电系统的控制芯片,ST6200C芯片内部自带控制程序,可以满足恒压恒流供电比较简单的应用,不需要重新烧录程序。 DC power supply circuit system, selection of the company ST model produced ST6200C an IC chip as a control power supply system, a control program built ST6200C chip, a relatively simple constant current power supply to meet the constant voltage application, without re-burning process .
