Abstract

本发明涉及一种埋钻冲孔工具。外套管的内孔一侧固定内套管，外套管的上下两端分别密封固定上月牙板和下月牙板，上月牙板和下月牙板上分别有与所述的内套管位置对冲内径相同的上、下通孔，上月牙板上密封固定水管接头，下月牙板上有多个喷水孔。

Description

埋钻冲孔工具
技术领域
本发明属于地质钻孔领域，特别涉及一种埋钻冲孔工具。
背景技术
钻机在施工过程中产生埋钻事故直接影响施工进度延误工期，处理事故费时，费力。目前没有专用工具来解决埋钻事故。
发明内容
为了克服现有技术的缺点，本发明提供一种埋钻冲孔工具。它结构简单，可以有效地解决埋钻事故，省时省力。
本发明解决其技术问题所采取的技术方案是：外套管的内孔一侧固定内套管，外套管的上下两端分别密封固定上月牙板和下月牙板，上月牙板和下月牙板上分别有与所述的内套管位置对冲内径相同的上、下通孔，上月牙板上密封固定水管接头，下月牙板上有多个喷水孔。
本发明结构简单，可以有效地解决埋钻事故，省时省力。
附图说明
下面结合附图和实施例对本发明进一步说明。
图1为本发明剖视图；
图2为本发明俯视图；
图3为本发明仰视图。
具体实施方式
如图1-图3所示，外套管3的内孔一侧固定内套管4，外套管3的上下两端分别密封固定上月牙板2和下月牙板5，上月牙板2和下月牙板5上分别有与所述的内套管4位置对冲内径相同的上、下通孔2、6，上月牙板2上密封固定水管接头1，下月牙板5上有多个喷水孔8。
所述的水管接头1用钻杆头替换。
一旦发生埋钻事故，即刻从立轴处将钻杆解开，将内套管4套在钻杆上，高压水源接通水管接头1，逐根接连后下放，通过喷水孔8向下喷水冲孔，直至冲到埋钻部位。在冲孔时可试着将钻杆转动，或者待泥浆开始往上返浆时，可尝试提钻，如提不动可继续冲孔，直到将钻杆全部提出为止。
