Abstract
The invention discloses a measuring line protection device of a sensor in a dynamic compaction process. The measuring line protection device comprises a high-strength steel pipe, wherein each one of the two ends of the high-strength steel pipe is connected with a connector through a thread. The two connectors are L-shaped and outlet directions of the two connectors are opposite. The steel pipe and the connectors are connected through inner and outer threads and are mounted oppositely. The device is buried into the part which is 1.5m below the surface of a road foundation; and all measuring lines of the sensor pass through the connectors and the steel pipe, and penetrate from the other connector. One connector is downwards inserted into a soil body of a measuring soil unearthing position and the other connector is upward. The measuring line protection device of the sensor can effectively protect the measuring lines from being cut off by sinking a soil body by compacting pressure, so as to guarantee the safety of the measuring lines; and meanwhile, the integrity and the accuracy of data of soil parameter change of a compacting process can be guaranteed, reworking caused by data loss and variation is avoided, and a work period is guaranteed.
Description
Technical field
The present invention relates to a kind of protective device, especially a kind of sensor survey line protective device that can be widely used in being embedded in the roadbed below the soil layer.
Background technology
Roadbed need to be buried the Changing Pattern that a series of sensors reflect soil body parameter in compacting process underground at the roadbed differing heights in work progress.Sensor need to be embedded in below the soil body, and survey line is drawn from the soil body of distance earth's surface certain depth.Traditional sensor survey line is embedded in underground not through any or just simple protection of process; cause in the subgrade compaction process survey line to be easy to damage; especially soft soil roadbed; because soil condition itself is relatively poor; during strong rammer; the subgrade settlement amount is very large, and survey line is damaged, and causes data to run off.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art, a kind of roadbed sensor survey line protective device is provided, this apparatus structure is simple, and is easy to use, and cost is low, effectively protects the sensor survey line to avoid that survey line is damaged in the subgrade compaction process.
For achieving the above object, the present invention adopts following technical proposals:
A kind of roadbed sensor survey line protective device comprises a high strength steel pipe, and described high strength steel pipe two ends connect a joint separately by screw thread.
Described two joints Wei “ ∟ " shape, and the outlet of two joints is towards the opposite.
Outer silk is done at high strength steel pipe of the present invention two ends, described joint Wei “ ∟ " shape, an end is done internal thread.
Steel pipe of the present invention is connected inside and outside silk and connects with joint, oppositely install.This device is imbedded following 1.5 meters of road bed, and all surveys line of sensor pass joint and steel pipe, pass from another joint.One joint inserts the soil body of the unearthed position of survey line downwards, and another joint upwards.This sensor survey line protective device; in the subgrade compaction process; can effectively protect survey line be not compacted the soil body that pressure causes sink cut off; guaranteed the safety of survey line; integrality and the accuracy of the data that Soil Parameters changes in the compacting process have been guaranteed simultaneously; avoid shortage of data and variation to cause and done over again, guaranteed the duration.
Description of drawings
Fig. 1 is that the present invention buries schematic diagram underground;
Wherein 1. surveys line, 2. high strength steel pipe, 3. joint.
The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of roadbed sensor survey line protective device.Comprise 1, two coupling 3 of a high strength steel pipe.Outer silk, desirable 1.5 meters of pipe range are done in described high strength steel pipe 2 two ends.Caliber is decided on the quantity of survey line 1, and all survey line 1 passes two joints 3 and high strength steel pipe 2.Described joint 3 Wei “ ∟ " shape, an end is done internal thread.Joint 3 is connected with high strength steel pipe by inside and outside silk connection, oppositely installs.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
Claims (2)
1. a roadbed sensor survey line protective device is characterized in that, comprise a high strength steel pipe, described high strength steel pipe two ends connect a joint separately by screw thread.
2. protective device as claimed in claim 1 is characterized in that, described two joints Wei “ ∟ " shape, and the outlet of two joints is towards the opposite.
