Detailed Description
The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present utility model, based on the embodiments of the present utility model.
As shown in fig. 1 and 2, an anti-collapse support device for road, bridge and tunnel construction comprises a bottom frame 1, wherein a top plate 2 is arranged on the bottom frame 1. The underframe 1 can take any form, such as a door shape, a frame shape or an arch shape, and only needs to meet the installation and support of the top plate 2; while the top plate 2 may be supported by the ejector in abutment with the tunnel face, or the top plate 2 may have a predetermined size to just form a support for the tunnel face. In order to prevent the roof 2 from being subjected to undesirable excessive pressure due to water seepage from the tunnel surface during the supporting process, the design of the disclosure has a cavity 3 in the roof 2, and a plurality of water through holes 4 communicated with the cavity 3 are arranged on the joint surface of the roof 2.
Therefore, the water seepage of the tunnel surface can enter and be accommodated in the cavity 3 through the water through holes 4, and the tunnel surface for smoothly discharging the water at this time does not act on the undesirable excessive pressure of the top plate 2, so that the supporting state of the top plate 2 is more stable and reliable.
In some embodiments, the bonding surface of the top plate 2 is covered with a water filtering film 6, and obviously, the water filtering film 6 can block broken stone and powder on the tunnel surface so as to prevent the situation that the cavity 3 is blocked by impurities. For example, the water filtering film 6 may be preset to be fixedly covered on the attaching surface of the top plate 2, or alternatively, the water filtering film 6 may be arranged at a corresponding position where the tunnel surface needs to be supported in advance, and then the top plate 2 is just abutted and attached to the water filtering film 6.
Preferably, the water passing hole 4 may have a tapered inner wall gradually reducing toward the cavity 3 side, so the water passing hole 4 may have a certain guide to the water seepage of the tunnel surface, so that the water is more likely to gather and fall into the cavity 3 through the water passing hole 4.
In some embodiments, the cavity 3 is further provided with a water absorbing member 5, and the water absorbing member 5 may absorb water falling into the cavity 3, for example, the water absorbing member 5 may be a sponge. Therefore, the cavity 3 can be restored to the use state for containing moisture more conveniently by replacing the water absorbing member 5.
In some embodiments, the top plate 2 is further provided with a drain hole 7 communicated with the cavity 3, and the drain hole 7 is provided with a pressure valve body 8, so that the drain hole 7 can be plugged by the pressure valve body 8. Meanwhile, the top plate 2 is further provided with a water pressing mechanism 9, and the water pressing mechanism 9 can press the water in the cavity 3 to one side of the drain hole 7, so that the water in the cavity 3 can have pressure intensity meeting the pressure threshold value of the pressure valve body 8 under the action of the water pressing mechanism 9, and the water can be discharged through the pressure valve body 8. It can be appreciated that the manner of draining the water in the cavity 3 by using the water pressing mechanism 9 and the pressure valve 8 has higher usability, for example, in the use process of the supporting device, the water pressing mechanism 9 can be controlled to press the water in the cavity 3 out without the need of relatively complicated disassembly and replacement of the water absorbing member 5.
Preferably, the pressure valve 8 is a pressure nozzle, so that the water discharged from the pressure nozzle will drop in mist form to the ground surface, and during this time, the droplets of the mist can degrade the dust in the tunnel. That is, the moisture collected in the cavity 3 can be used for dust degradation of the tunnel. Preferably, the cavity 3 can not only passively collect water seepage from the tunnel surface, constructors can actively pour water into the cavity 3, and then the water can be regularly pressed out through the water pressing mechanism 9 to degrade dust in the tunnel, so that the collapse-preventing support device has the multifunctional use characteristics.
In an exemplary embodiment, the pumping mechanism 9 includes a pumping plate 10 sealingly slidably coupled within the cavity 3 and a driving member 11 for driving the pumping plate 10 to slide. For example, an elastic member 12 is disposed between the water pressure plate 10 and the inner wall of the cavity 3, and the driving member 11 includes an electromagnet 13. In more detail, when the electromagnet 13 is electrified to generate magnetic force, the electromagnet can absorb the water pressure plate 10 to slide, and at the moment, the elastic piece 12 is pressed by the water pressure plate 10 to be in a stable compression state; when the electromagnet 13 is powered off, the elastic element 12 restores to a natural state and pushes the water pressing plate 10 to press the water in the cavity 3 out of the water draining hole 7. Alternatively, the driving member 11 may be an electric cylinder, an oil cylinder or an air cylinder provided on the top plate 2.
The foregoing is merely a preferred embodiment of the utility model, and it is to be understood that the utility model is not limited to the form disclosed herein but is not to be construed as excluding other embodiments, but is capable of numerous other combinations, modifications and environments and is capable of modifications within the scope of the inventive concept, either as taught or as a matter of routine skill or knowledge in the relevant art. And that modifications and variations which do not depart from the spirit and scope of the utility model are intended to be within the scope of the appended claims.
