Description
technical field
The invention belongs to shield ventral brush Performance Detection technical field, relate generally to a kind of shield ventral brush experimental facilities.
Background technology
Shield machine 1-1 as shown in Figure 1, a kind ofly for the soft soil tunnel tunneling, to construct, there is metal shell 1-3, complete machine and auxiliary equipment are housed in shell, carry out under its shielding that soil body 1-2 excavation, soil quarrel rafting, complete machine advances and the operation such as concrete pipe sheet 1-11 installation, thereby make the tunnel construction machinery of tunnel once-forming.In order to prevent that underground water, outer soil, the lining cutting back side slip casting 1-11 etc. from flowing into tunnel, usually in shield machine afterbody annular solder three road shield ventral brushes be shield ventral brush I 1-6, shield ventral brush II 1-8, shield ventral brush III 1-10 to form two cavitys be cavity I 1-7, cavity II 1-9, thereby and play good sealing function to injecting a certain amount of grease-filled thing in two cavitys by grease ascending pipe I 1-4, grease ascending pipe II 1-5 between shield structure afterbody housing 1-3 and concrete pipe sheet 1-12.
As shown in Figure 2, the shield ventral brush is comprised of upper and lower two block plate inner clip wire brush 2-4, and the top steel plate is called guard shield 2-3, not frayed for the protection of wire brush 2-4, and the bottom steel plate is called pressure strip 2-5, pushes down wire brush 2-4 and is close to the concrete pipe sheet outer wall.Pressure strip 2-5 adopts the camber structure, and under the state of not stressing, wire brush 2-4 all presents the angle of 120 ° of arcs.Under normal stress, the guard shield 2-3 of shield ventral brush, wire brush and 2-4 pressure strip 2-5 and section of jurisdiction close contact.Guard shield 2-3, pressure strip 2-5, stainless steel wire 2-4 are fixed in pedestal steel plate 2-1 by pin 2-2, form monoblock shield ventral brush.
In the snakelike progradation of shield machine, the shield ventral brush is done relative fricting movement with concrete pipe sheet on the one hand, on the other hand due to the attitude of shield machine adjustment, little when large during gap between shield machine housing and section of jurisdiction, the shield ventral brush is done reciprocal bending campaign with respect to concrete pipe sheet.Principle according to the shield ventral brush in the shield machine course of work is known will ensure that tail sealing is functional, and the abrasion resistance of shield ventral brush and elasticity are key indexs.
At present domestic existing a lot of producers that produce the shield ventral brush, but the equipment all shield ventral brush performance not detected in industry, unit in charge of construction is selecting in the shield ventral brush, abrasion resistance and the elasticity that determines shield ventral brush sealing performance is detected without reliable equipment, can only be intuitively, unavoidable buying, to the product of inferior quality, is produced and is buried potential safety hazard for construction.
summary of the invention
The objective of the invention is to propose a kind of shield ventral brush experimental facilities, before every batch of shield ventral brush is used, the abrasion resistance of sample testing product and elasticity, guarantee that shield-tunneling construction carries out safely smoothly.
The present invention completes the technical scheme that its invention task takes:
