Abstract
The utility model discloses a seismic transverse wave excitation apparatus. The apparatus comprises a transverse wave reception instrument (1) and a group of geophones (2) embedded underground, and further comprises a compact wooden board (6) fixed on the ground by a group of ground anchor nails (5), wherein the transverse wave reception instrument (1) is connected with a sledge hammer (8) through a synchronous switch line (3), and is connected with the group of geophones (2) by wires. According to the utility model, the compact wooden board is closely contacted with the ground by the group of ground anchor nails, the group of geophones are embedded underground near the compact wooden board, and the geophones are connected with the transverse wave reception instrument by wires; during a test, an operator stands on the compact wooden board, and hits two ends of the compact wooden board by the sledge hammer so as to generate two sets of seismic transverse waves of opposite phases, data of the sledge hammer hitting the compact wooden board is transmitted to the transverse wave reception instrument by the synchronous switch line connected with the sledge hammer, and the transverse wave reception instrument receives the data from the sledge hammer and carries out comprehensive analysis with data received by the geophones, thereby obtaining the test result.
Description
Technical field
The utility model relates to the excitation apparatus of a kind of excitation apparatus, particularly a kind of secondary wave.
Background technology
Often need carry out the test of artificial earthquake shear wave in the engineering investigation, the mode of artificial excitation's secondary wave mainly contains two kinds, and a kind of is to adopt the boring mode of excitation, and another kind is plank ballast mode of excitation.But many time, be subjected to the influence of test site, it is available not have boring; Or adopt plank ballast mode of excitation, and when adopting plank ballast mode of excitation at present, need to use the deadweight automobile to carry out ballast, because early stage, there was the situation that the deadweight automobile can not arrive in test site, and test can't be carried out.Therefore need to adopt another kind of secondary wave mode of excitation and device.To finish the test of artificial earthquake shear wave.
Summary of the invention
The purpose of this utility model is, a kind of excitation apparatus of secondary wave is provided, and solves at the boring mode of excitation and plank ballast mode of excitation can not use or inconvenience when using, and carries out the problem of artificial earthquake transverse wave testing, to overcome the deficiencies in the prior art.
The technical solution of the utility model:
A kind of excitation apparatus of secondary wave comprises shear wave receiving instrument and the one group of wave detector that is embedded in below ground; Also comprise the fine and close plank that fixes on the ground through one group of ground holdfast; The shear wave receiving instrument is connected with sledgehammer through the synchro switch line, and the shear wave receiving instrument is connected with one group of wave detector through lead.
In the aforementioned means, high-strength Rubber end is inlayed at the two ends of described fine and close plank.
Compared with prior art, the utility model utilizes one group of ground holdfast that fine and close plank is tightly linked with ground, and near the below ground fine and close plank is embedded with one group of wave detector, and the detector via lead is connected with the shear wave receiving instrument.During test, operating personnel stand on the fine and close plank, with the fine and close plank of sledgehammer hammering two ends, form two groups of opposite secondary waves of phase place, the data of the fine and close plank of sledgehammer hammering pass to the shear wave receiving instrument by the synchro switch line that is connected with sledgehammer, and the data that the shear wave receiving instrument will receive from data and the wave detector of sledgehammer are carried out analysis-by-synthesis and obtained test result.Utilizing one group of ground holdfast is the friction force that increases fine and close plank and ground with the purpose that ground links tightly with fine and close plank, and fine and close plank slides along ground when preventing hammering.
Description of drawings
Fig. 1 is the application synoptic diagram when carrying out the artificial earthquake transverse wave testing with device of the present utility model.
Being labeled as in the accompanying drawing: 1-shear wave receiving instrument, 2-wave detector, 3-synchro switch line, the high-strength Rubber end of 4-, 5-ground holdfast, the fine and close plank of 6-, 7-operating personnel, 8-sledgehammer.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, but not as to any restriction of the present utility model.
A kind of excitation apparatus of secondary wave as shown in Figure 1, comprises shear wave receiving instrument 1 and the one group of wave detector 2 that is embedded in below ground; Also comprise the fine and close plank 6 that fixes on the ground through one group of ground holdfast 5; Shear wave receiving instrument 1 is connected with sledgehammer 8 through synchro switch line 3, and shear wave receiving instrument 1 is connected with one group of wave detector 2 through lead.High-strength Rubber end 4 is inlayed at the two ends of fine and close plank 6.
Application example of the present utility model
When carrying out the artificial earthquake transverse wave testing, elder generation carries out smooth to test site, with three ground holdfasts 5 fine and close plank 6 is fixed on the ground then, just guarantees that fine and close plank 6 closely contacts with ground.2, two wave detectors 2 of two wave detectors are installed near fine and close plank 6 are connected with shear wave receiving instrument 1 through lead, shear wave receiving instrument 1 is connected with sledgehammer 8 through synchro switch line 3.Check that shear wave receiving instrument 1 is in good working order.After ready, lift sledgehammer 8 by operating personnel 7 and carry out secondary wave and excite in the fine and close plank of hammering 6 two ends respectively, form two groups of opposite secondary waves of phase place.Utilize three ground holdfasts 5 that fine and close plank 6 is tightly linked with ground, can increase the friction force on fine and close plank 6 and ground, fine and close plank 6 slides along ground when preventing hammering, causes test error.Fine and close plank 6 two ends are inlaid with high-strength Rubber end 4, can prevent sledgehammer 8 repeatedly the fine and close plank 6 of hammering cause fine and close plank 6 two ends to be broken too early; Repeat said process up to end of test (EOT).
Claims (2)
1. the excitation apparatus of a secondary wave comprises shear wave receiving instrument (1) and is embedded in one group of wave detector (2) of below ground; It is characterized in that: also comprise the fine and close plank (6) that fixes on the ground through one group of ground holdfast (5); Shear wave receiving instrument (1) is connected with sledgehammer (8) through synchro switch line (3), and shear wave receiving instrument (1) is connected with one group of wave detector (2) through lead.
