The first embodiment is as follows:
referring to fig. 1, 2 and 4, a supporting frame with a settlement early warning prompt for geotechnical engineering construction comprises a beam 1, a settlement early warning structure 4 and a telescopic rod 7, wherein side plates 2 are respectively installed on the two side surfaces of the beam 1, a rigid spring 12 is installed on the bottom surface of each side plate 2, and a lifting column 3 is installed at the bottom of each rigid spring 12;
specifically, the stability of the whole supporting frame is kept through the cross beam 1, the lifting columns 3 are matched with the side plates 2 to lift along with the cross beam 1, and the settlement early warning structure 4 is convenient to trigger through the rigid springs 12.
As shown in fig. 3, a braced frame is used in geotechnical engineering construction with subside early warning suggestion, including subsiding early warning structure 4, one side surface mounting of curb plate 2 has subsides early warning structure 4, subside early warning structure 4 including trigger bar 401, alarm switch 402, alarm 403 and pressure sensor 404, one side surface mounting of curb plate 2 has trigger bar 401, the surface mounting of lift post 3 has alarm switch 402, and alarm switch 402 is located the below of trigger bar 401, alarm 403 is installed in the front of crossbeam 1, the internally mounted of backup pad 6 has pressure sensor 404, alarm switch 402 and alarm 403 electric connection.
Specifically, when taking place to subside at the tunnel top, curb plate 2 can extrude rigid spring 12, makes curb plate 2 slowly be close to lift post 3 to drive trigger bar 401 and descend, after the early warning scope that reachs and subside, trigger bar 401 can touch alarm switch 402, thereby makes alarm 403 carry out the early warning, reminds the staff.
Can detect the support pressure at tunnel top through pressure sensor 404, the staff of being convenient for knows current support pressure in real time, through the early warning effect who subsides early warning structure 4, can carry out the early warning to the condition of subsiding at tunnel top, and the operating personnel of being convenient for withdraws in time to guarantee operating personnel's personal safety, improve braced frame's security.
The top surface mounting of crossbeam 1 has bracing piece 5, and the top surface mounting of bracing piece 5 has curved backup pad 6, and the both ends of backup pad 6 are connected with the top of curb plate 2.
Specifically, through the cooperation of bracing piece 5 and curved backup pad 6, can support the top ground in tunnel, guarantee the stability of tunnel structure.
The bottom surface of the base 9 is provided with a conical fixing rod 10, and the conical fixing rod 10 is positioned in the middle of the two groups of lifting columns 3.
Specifically, the stability of the structure above it is maintained by the base 9, and the entire supporting frame is stabilized by inserting the tapered fixing rod 10 into the soil of the roadway.
Example two: as shown in fig. 2, a braced frame is used in geotechnical engineering construction with subside early warning suggestion, telescopic link 7 is installed to the bottom surface equidistance of crossbeam 1, base 9 is installed to the bottom of telescopic link 7, the front slidable mounting of crossbeam 1 has scissors fork expansion bracket 8, and it is located the centre of two sets of telescopic links 7 to cut fork expansion bracket 8, the surface mounting of telescopic link 7 has branch 11, and branch 11 keeps away from the one end of telescopic link 7 and is connected with the bottom of crossbeam 1, the bottom of cutting fork expansion bracket 8 and the front sliding connection of base 9.
It is specific, when needs support the not tunnel of co-altitude, because the ground in tunnel is not level and smooth, when carrying out the adjustment of height through lift post 3 alone, whole braced frame's stability is not enough, the raising and lowering functions of raising and lowering functions through telescopic link 7 and the telescopic function's of scissor type expansion bracket 8 assistance work, promote crossbeam 1 and rise and reduce, thereby make crossbeam 1 promote curved backup pad 6 again and carry out the auxiliary stay to the tunnel of high difference, it further supports to cooperate branch 11 again, guarantee crossbeam 1's stability, from this through the height of adjusting braced frame, make it be fit for not tunnel or the tunnel of equidimension height not, thereby improve braced frame's extensive practicality.
