Description
Technical field
The utility model relates to a kind of Ground Subsidence Monitoring point apparatus, particularly is applied to a kind of Ground Subsidence Monitoring point apparatus in building operations and subway work field.
Background technology
Locate extensively distributing weak soil in that China is riverine, along the lake etc., along with Chinese Urbanization degree ground improves, urban land is increasing, thereby carries out above the soil that forces a part of building operations project to have to form reclaiming land from a lake.The characteristics of soft foundation are that natural moisture content is big, air space ratio is big, compression coefficient is high, intensity is low and have engineering geological properties such as creep properties that engineering geological conditions is relatively poor, must take practicable technical measures.For soft foundation, what generally take at present is pile foundation based process mode.This mode can both be received good effect for foundation bearing force intensity and settlement request, but often be difficult to control for the top surface settlement that soft foundation causes, excessive sedimentation may make ponding Cheng Chi in the place, ground, even causes the cracking destruction of machinery equipment, crane runway and water, electricity and gas pipe-line system.Known Ground Subsidence Monitoring point apparatus complex structure, installation inconvenience are not suitable for characteristics such as building operations duration anxiety.
The utility model content
Existing surface settlement device is expensive in order to overcome, complex structure, awkward deficiency, and the utility model provides a kind of easy for installation, Ground Subsidence Monitoring point apparatus that the degree of accuracy is high.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of Ground Subsidence Monitoring point, comprise that is inserted a monitoring rod that detects in the hole, it is characterized in that: the aperture in described detection hole is bigger than hole body diameter, the hole body degree of depth is greater than 1m, the aperture degree of depth is greater than 50mm, the aperture inwall is lined with a steel ring, adds above the steel ring to be stamped top cover, and described top cover is concordant with ground, top cover is connected by connector in a side with steel ring, the hole inner bottom part in described detection hole is filled with the weak concrete of 100～150mm, and the center of hole body is inserted with a monitoring rod, is filled with fine sand in the hole body, described monitoring rod is perpendicular to be put, submerge in the weak concrete in its lower end, its head is positioned at the aperture, is lower than top cover.
The diameter 150mm in the aperture in described detection hole, the aperture degree of depth is 50～80mm, and the diameter of hole body is 100mm, and the hole body degree of depth is deeper than more than the maximum frozen soil layer absolute altitude 300mm.
Described monitoring rod is that diameter is the reinforcing bar of Φ 20mm, its top be shaped as through the polishing circular arc.
The connector of described top cover and steel ring is to open bolt or hinge.
The beneficial effects of the utility model are as follows:
For protecting the reinforcing bar monitoring point not by vehicle or artificial destruction, a steel ring is laid in the upper end, and steel ring is added a cover protection.Top cover and steel ring adopt connector to be connected, can prevent that vehicle etc. from causing top cover to be shifted.
The utility model is imbedded the monitoring point in the undisturbed soil by boring, and the false situation of data of having avoided the road surface, top may exist duricrust etc. to cause is to guarantee to reflect in time, accurately the actual sedimentation situation on ground.And simple in structure, easy for installation, the degree of accuracy is high, has overcome traditional ground monitoring device complex structure, awkward deficiency.
The utility model can be widely used in the Ground Subsidence Monitoring on the building operations project that soft foundation is carried out, and the Ground Subsidence Monitoring of subway engineering etc.

Reference numeral: 1-top cover, 2-steel ring, 3-monitoring rod, 4-fine sand, 5-detect hole, 6-weak concrete, 7-connector.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
A kind of Ground Subsidence Monitoring point, comprise that is inserted a monitoring rod 3 that detects in the hole 5, it is characterized in that: the aperture in described detection hole is bigger than hole body diameter, the hole body degree of depth is greater than 1m, the aperture degree of depth is greater than 50mm, the aperture inwall is lined with a steel ring 2, adds above the steel ring 2 to be stamped top cover 1, and described top cover 1 is concordant with ground, top cover 1 is connected by connector 7 in a side with steel ring 2, the hole inner bottom part in described detection hole is filled with the weak concrete 6 of 100～150mm, and the center of hole body is inserted with a monitoring rod 3, is filled with fine sand 4 in the hole body, described monitoring rod 3 perpendicular putting, submerge in the weak concrete 6 in its lower end, its head is positioned at the aperture, is lower than top cover 1.
The diameter 150mm in the aperture in described detection hole, the aperture degree of depth is 50～80mm, and the diameter of hole body is 100mm, and the hole body degree of depth is deeper than more than the maximum frozen soil layer 5 absolute altitude 300mm.
Described monitoring rod 3 is that diameter is the reinforcing bar of Φ 20mm, its top be shaped as through the polishing circular arc.
Described top cover 1 is to open bolt or hinge with the connector 7 of steel ring 2.
Embodiment is referring to shown in Figure 1, a kind of Ground Subsidence Monitoring point, and key step is: it is dark at first to adopt 150mm water to bore boring 50～80mm, adopt Φ 100mm water to bore boring then, hole depth is not less than 1m, guaranteeing going deep into undisturbed soil at the bottom of the hole, and is deeper than more than the maximum frozen soil layer absolute altitude 300mm.Get surflaes in the clear opening, insert 100～150mm weak concrete 6 in the hole, insert the Φ 20mm reinforcing bar 3 of processing in advance then, the upper end is polished into circular arc type, and the top mark height is in about the 50mm of ground.After treating that reinforcing bar is firm, remainder is closely knit with fine sand 4 fillings in the hole, and the steel bar end part is not filled, so that monitoring.
