Abstract
The utility model relates to the field of tunnel construction, in particular to a sound attenuation trolley for tunnel blast working. The sound attenuation trolley for tunnel blast working is used for solving the problems that due to noise pollution which is produced by the existing tunnel blast working, the construction process is influenced, and the normal life, work and study of citizens are disturbed. The sound attenuation trolley comprises a frame and walking wheels which are mounted below the frame, wherein a sound attenuation box is arranged above the frame; a shock wave impact force buffer chamber which is full of straw, a sound wave absorption buffer chamber which is full of cotton wool, a sound wave absorption obstruction chamber which is full of saw dust and a forced obstruction wall which is made of wood plates are arranged from tailstock to headstock in sequence in the sound attenuation box. According to the sound attenuation trolley for tunnel blast working, the noise reduction effect can reach 60%, the noise pollution level is a better level, the night construction requirement can be completed met, the normal work, life and study of people can be ensured, the construction efficiency is greatly improved, the construction period is shortened, the construction progress is ensured, and the application and popularization prospects are better.
Description
Technical field
The utility model relates to constructing tunnel field, is specially a kind of Tunnel Blasting construction noise reduction chassis.
Background technology
In constructing tunnel process; often can run into work items next-door neighbour residential block; execution conditions complexity; how controlling construction noise pollutes especially noise of blasting and pollutes and will directly affect construction speed; in order to reduce noise pollution, reduce to greatest extent the interference to citizen's normal life, working and learning, constructor will move heaven and earth to reduce noise pollution; but up to the present, also do not have effective measure to solve this construction difficult problem.
Summary of the invention
The utility model, for the noise pollution that solves existing tunnel blast working and produce affects construction speed, disturbs the problem of citizen's normal life, working and learning, provides a kind of Tunnel Blasting construction noise reduction chassis.
The utility model is to adopt following technical scheme to realize: Tunnel Blasting construction noise reduction chassis, comprise vehicle frame, be installed on the road wheel of vehicle frame below, vehicle frame top is provided with noise reduction casing, in noise reduction casing and by the tailstock, sets gradually and is filled with that the shock wave impact force cushion chamber of straw, the wave absorption cushion chamber that is filled with cotton-wool, the wave absorption that is filled with sawdust hinder chamber and wall is blocked in the pressure of being made up of plank to headstock.
Described vehicle frame front end is provided with the towing hook being connected with power set.
Described vehicle frame is provided with the braking mechanism for controlling road wheel, because this chassis will move in inclined shaft, adopts braking mechanism to be convenient to timely manipulation, and this braking mechanism can adopt existing known features.
Adopt structure design of the present utility model, this noise reduction chassis principle of noise reduction: detonate to produce to impact and involve sound wave in blast area, to running tunnel high-speed motion, to installing soundproof measures section additional, carry out the absorption of shock wave impact force and buffering by the shock wave impact force cushion chamber that is filled with straw, then by being filled with slow wave absorption and the obstruction district of being depressed into of wave absorption cushion chamber of cotton-wool, arrive pressure vertical partition wall by being filled with after the wave absorption obstruction chamber of sawdust enters sound wave blocking-up district again, shock wave and sound wave are consumed large portion, reach resistance sound noise reduction.Field data show, add after noise reduction chassis, noise of blasting is reduced to 72 decibels by 160 decibels of past, and flat effect reaches 60%, and noise pollution rank is better, meet the requirement that carries on construction work at night completely, guarantee that people normally work, living and studying, and greatly improve construction effect, shorten the construction period, guarantee construction speed, there is good application prospect.

The specific embodiment
Tunnel Blasting construction noise reduction chassis, as shown in Figure 1, comprise vehicle frame 1, be installed on the road wheel 2 of vehicle frame below, vehicle frame top is provided with noise reduction casing 3, in noise reduction casing and by the tailstock, sets gradually and is filled with that the shock wave impact force cushion chamber 4 of straw, the wave absorption cushion chamber 5 that is filled with cotton-wool, the wave absorption that is filled with sawdust hinder chamber 6 and wall 7 is blocked in the pressure of being made up of plank to headstock.Vehicle frame 1 front end is provided with the towing hook 8 being connected with power set, and vehicle frame 1 is provided with the braking mechanism 9 for controlling road wheel.
When concrete making, noise reduction chassis size can be according to the design of inclined shaft barrel size, and noise reduction chassis is high 4 meters conventionally, wide 4.5 meters, long 5.5 meters, the wherein long 1m of shock wave impact force cushion chamber, the long 1.5m of wave absorption cushion chamber, wave absorption hinders the long 3m in chamber, forces blocking-up wall thickness 5cm.When use, by loader, noise reduction chassis is dragged to noise-reducing door in inclined shaft, jointly abates the noise with noise-reducing door.
