But existing pore water pressure detector can not measure the pore water pressure of each degree of depth by continuous print, measures multiple spot Pore water pressure is accomplished by the different pre-buried pore water pressure sensors in place, and workload is big, and the when that multiple spot being pre-buried just Needing to bore multiple hole, the adverse effect for engineering is the biggest.
Utility model content
The purpose of this utility model is that for the problems referred to above, it is provided that a kind of pore water pressure detector, by arranging Spiral continuous print sensor, by multiple sensors comprehensively in same detector, the most spiral be designed to improve whole The comprcssive strength of individual detector, also allows for buried via hole.
This utility model is achieved through the following technical solutions above-mentioned purpose: a kind of pore water pressure detector, including hole Gap WG, permeable stone, described pore pressure gauge is connected with permeable stone, and pore pressure gauge, permeable stone are sealed in tube chamber In, tube chamber is provided with permeable hole with permeable stone corresponding position, pore water is detected by permeable hole;3-4 tube chamber is connected to one Playing one pore water pressure detector of composition, to realize continuity point detection, the permeable hole of each tube chamber helically rises arrangement, permissible Permeable hole is avoided to be positioned at the tube chamber pressure inequality that homonymy brings, flimsy problem at permeable hole;Tube chamber is externally provided with and water flowing The external screw thread that hole is parallel, spiral sinks, convenient boring and buried via hole;Pore pressure gauge cable end piece is connected with joint, and joint is even Being connected in the union joint at tube chamber top, the bottom of tube chamber is provided with the some connectors matched with cable;The cavity wall of each tube chamber Inside it is provided with wire, is connected in parallel each union joint that each connector of bottom is corresponding with top, the union joint between adjacent tube chamber and company Interface is removably connected by wire;The wire of the tube chamber of top is connected with controller, the letter of controller each pipeline of identification Breath shows the pore water pressure of different depth.
Further, the discontinuous connection of each tube chamber, junction is filled with bentonite section or silica gel sealing material, can non-company Continuous detection, saves the trouble of buried via hole of repeatedly holing.
Further, permeable hole limit is provided with scale mark, it is simple to the labeled test degree of depth.
Further, distinguished by different colours between each connector and union joint, prevent between connector and union joint Insert mixed, it is simple to distinguish.
Further, distinguished by different digital between each connector and union joint, prevent between connector and union joint Insert mixed, it is simple to distinguish.
Concrete operations mode is as follows:
First according to the needs of test point number, being sequentially connected with each tube chamber, each tube chamber carries out label or color mark, depends on The connector of each tube chamber of secondary connection and union joint, distinguish No. 1 tube chamber, No. 2 tube chambers, No. 3 tube chambers, then No. 1 pipe the most from down to up The union joint in chamber successively with No. 1 connector, No. 1 union joint of No. 2 tube chambers, No. 1 connector of No. 3 tube chambers, No. 1 union joint phase Even, the union joint of No. 2 tube chambers is connected with No. 2 connectors, No. 2 union joints of No. 3 tube chambers successively, last wire and No. 3 tube chambers Wire be connected with controller, controller shows the signal that each union joint receives.
This utility model has the advantages that
The most permeable holes are arranged continuously and can be realized part continuous detecting, it is also possible to save the work of deduplication boring buried via hole Amount, improves work efficiency, cost-effective.
2. spiral permeable hole be designed to strengthen the comprcssive strength of whole detector, externally threaded design also makes whole Individual detector is more easy to boring and buried via hole.
