背景技术Background technique
地表沉降监测往往用于体现工程施工对周边地层的影响，目前较为普遍的是用浅层地钉作为监测标识，该标识存在一定局限，由于监测点位于地面表层，仅能代表表层沉降，表层为路面结构层，与原状土性状不同，且地面表层往往受路面车辆碾压及反复的动载影响，并在冻土层范围内，受季节性冻融影响显著，因此常有地面以下已出现空洞但监测数据未有体现或体现相对滞后的情况出现，因此监测获取的数据不能很好的代表工程施工所引起的表层以下一定深度的垂直位移，对分析评价工程施工给周边环境带来的安全风险造成一定影响。Surface subsidence monitoring is often used to reflect the impact of engineering construction on surrounding strata. At present, shallow ground nails are commonly used as monitoring marks. This mark has certain limitations. Since the monitoring point is located on the surface of the ground, it can only represent the surface settlement. The surface is The pavement structure layer is different from the undisturbed soil, and the ground surface is often affected by road vehicle rolling and repeated dynamic loads, and in the permafrost layer, it is significantly affected by seasonal freeze-thaw, so there are often holes below the ground However, the monitoring data does not reflect or reflects the relatively lagging situation. Therefore, the data obtained by monitoring cannot well represent the vertical displacement at a certain depth below the surface caused by engineering construction, and is useful for analyzing and evaluating the safety risks brought by engineering construction to the surrounding environment. cause a certain impact.
发明内容Contents of the invention
为进一步规范地表沉降监测点的安设，更为精确的获取施工对地面的影响，本实用新型专利提供套筒式沉降监测点装置，外部套筒能尽量避免其内的监测点受地面环境的干扰，可掀盖套筒又能够在施测完成后覆盖以完好恢复路面，避免影响路面平整。In order to further standardize the installation of surface settlement monitoring points and more accurately obtain the impact of construction on the ground, the utility model patent provides a sleeve-type settlement monitoring point device. The outer sleeve can try to avoid the monitoring points inside it from being affected by the ground environment interference, the flip-cover sleeve can be covered after the test is completed to restore the road surface intact and avoid affecting the smoothness of the road surface.
套筒式沉降监测点装置，其特征在于：The sleeve type settlement monitoring point device is characterized in that:
该装置包括沉降监测点及其套筒，套筒采用中空带顶盖钢管，顶盖能够掀起，沉降监测点内置于套筒中心。The device includes a settlement monitoring point and its sleeve. The sleeve is a hollow steel pipe with a top cover. The top cover can be lifted, and the settlement monitoring point is built in the center of the sleeve.
进一步，顶盖与筒身通过可向上提拉的构件连接，该构件由与套筒筒身固定的空心圆柱和与顶盖固定的圆杆组成，空心圆柱套在圆杆外，圆杆顶端与顶盖固定，圆杆底端为直径尺寸大于空心圆柱内径的圆形底座。Further, the top cover is connected to the barrel body through a member that can be pulled upwards. The member is composed of a hollow cylinder fixed to the sleeve body and a round rod fixed to the top cover. The top cover is fixed, and the bottom end of the round rod is a circular base whose diameter is larger than the inner diameter of the hollow cylinder.
圆杆底端略大于空心圆柱内径，以避免圆杆从空心圆柱中脱离，顶盖与套筒分离。顶盖掀起时揭露内置沉降监测点，顶盖覆盖时与其周边地面持平。The bottom end of the round rod is slightly larger than the inner diameter of the hollow cylinder, so as to prevent the round rod from breaking away from the hollow cylinder, and the top cover is separated from the sleeve. When the top cover is lifted, the built-in settlement monitoring point is exposed, and when the top cover is covered, it is level with the surrounding ground.
进一步，套筒与沉降监测点之间用砂石填实，以保持套筒及沉降监测点的稳定。Further, the space between the sleeve and the settlement monitoring point is filled with sand to keep the sleeve and the settlement monitoring point stable.
进一步，沉降监测点，顶端制作成球形，底部制作成锥形。Further, for the settlement monitoring point, the top is made into a spherical shape, and the bottom is made into a cone.
进一步，套筒长度应至少超过路面结构层，内径13～14cm，长度70～80cm。Furthermore, the length of the sleeve should at least exceed the pavement structure layer, with an inner diameter of 13-14 cm and a length of 70-80 cm.
进一步，所述沉降监测点为直径20～32mm的螺纹钢，长度不小于1m，超过路面结构层及该地区最大冻土线至少20cm。Further, the settlement monitoring point is a rebar with a diameter of 20-32mm, and the length is not less than 1m, and exceeds the road surface structure layer and the maximum permafrost line in the area by at least 20cm.
本装置套筒及监测点深度合理，套筒顶盖封闭，且设置有支撑垫块，防尘、防压，监测时便于操作，利于保护。The depth of the sleeve and the monitoring point of the device is reasonable, the top cover of the sleeve is closed, and a support pad is provided to prevent dust and pressure, and it is easy to operate during monitoring and beneficial to protection.
