The following describes the structures of a self-deformation tire type track construction vehicle, a self-adaptive section engineering transport vehicle and a self-deformation tire type concrete construction vehicle:
the self-deformation tire type track construction vehicle as shown in fig. 5 and 6 comprises a frame 1, a hoisting device 9 is arranged below the frame 1, a group of rail-changing jacking devices are connected to two sides of the frame 1 in a sliding manner, and each rail-changing jacking device comprises: each horizontal guide pipe 2 is connected with a vertical sleeve 3; the supporting tube 5 is sleeved on the lower side of each vertical sleeve 3, and the traveling device 7 is hinged to the lower side of the supporting tube 5 of the rail-changing jacking device.
The frame 1 at the two sides of the hoisting device 9 is also provided with a supporting platform 8, the supporting platform 8 is provided with a power system formed by a generator, a control cabinet, a hydraulic oil tank and a gear pump motor which are mutually matched,
a horizontal oil cylinder is arranged in the horizontal guide pipe 2, the horizontal guide pipe 2 can be controlled to stretch out and draw back along the horizontal direction through the horizontal oil cylinder, and then the traveling device 7 is driven to form a track change, and further the span of the self-deformation tire type track construction vehicle is controlled.
The vertical sleeve 3 is provided with a longitudinal oil cylinder which is connected and matched with the supporting tube 5, and the longitudinal oil cylinder can control the extension and retraction of the supporting tube 5 so as to control the longitudinal height of the rack.
An adjusting oil cylinder connected and matched with the walking device 7 is arranged in the supporting tube 5, the walking device 7 can deflect by jacking an output shaft of the adjusting oil cylinder, and therefore the walking device 7 has the ability of walking on the arc-shaped inner wall of the tunnel.
The self-deformation tire type track construction vehicle is a device produced by the company, belongs to the prior art, and has the patent application number of 201710380054.9, so the structure of the self-deformation tire type track construction vehicle is only briefly explained here.
As shown in fig. 1 and 2, the self-adaptive section engineering transport vehicle comprises a vehicle body 11, wherein a set of walking wheels 12 are arranged on the vehicle body 11, power devices 14 correspondingly matched with the walking wheels 12 are arranged on the vehicle body 11, control chambers 13 are arranged at two ends of the vehicle body 1, a material loading plate 15 is arranged at the upper part of the vehicle body 1, and a set of material limiting columns 15a are uniformly distributed on the material loading plate 15. Due to the special driving environment in the tunnel, workers need to drive the adaptive section engineering transport vehicle in the control room with the same driving direction.
The adaptive cross-section engineering transport vehicle is a device produced by the company, belongs to the prior art, and has the patent application number of 201520267607.6, so the detailed structure of the adaptive cross-section engineering transport vehicle is not described in detail. The difference of the self-adaptation section engineering transport vechicle in this scheme and above-mentioned prior art lies in that frame one end does not set up discharge apparatus, and the interval between two walking wheels 12 on the self-adaptation section engineering transport vechicle width direction will be greater than the width of reinforcing bar base member, makes the self-adaptation section engineering transport vechicle walk the wheel and can not press the reinforcing bar base member when marcing in tunnel 30 like this.
As shown in fig. 3 and 4, the self-deformation tire type concrete construction vehicle includes a vehicle frame 21, a concrete mixing tank 22 is disposed on the vehicle frame 21, a group of rail-changing jacking devices are uniformly distributed on the vehicle frame 21, a traveling device is connected to each rail-changing jacking device, and the structures of the rail-changing jacking devices and the traveling devices are the same as those of the rail-changing jacking devices and the traveling devices in the self-deformation tire type rail construction vehicle, so they are not described herein. The frame 21 is also provided with a control chamber 23 correspondingly matched with the concrete mixing tank 22, the track-changing jacking device and the travelling device, and the control chamber is internally provided with a control board for controlling the concrete mixing tank 22, the track-changing jacking device and the travelling device.
Through the self-deformation tire type track construction vehicle, the self-adaptive section engineering transport vehicle and the self-deformation tire type concrete construction vehicle, the vehicle can run on the arc-shaped inner wall of the tunnel 30, the process that the temporary walking rail of the construction equipment needs to be erected in the tunnel 30 before construction in the prior art is omitted, the preparation period before construction is greatly saved, the construction cost is reduced, and the damage to the inner wall of the tunnel 30 when the temporary walking rail is erected is avoided.
Because the reinforcement matrix 40 is located at the bottom of the tunnel 30, and the wheels of the self-deformation tire type track construction vehicle, the self-adaptive section engineering transport vehicle and the self-deformation tire type concrete construction vehicle all walk on the arc-shaped inner wall of the tunnel when entering and exiting the tunnel 30, the reinforcement matrix cannot be pressed. Therefore, after the concrete is poured into the reinforcement matrix 40, even before the concrete is not solidified to form the roadbed matrix, the movement of the construction machines such as the self-deformation tire type track construction vehicle, the self-adaptive section engineering transport vehicle and the self-deformation tire type concrete construction vehicle in the tunnel 30 is not influenced, and the problem that the construction equipment is limited to enter and exit the tunnel 30 before the roadbed matrix is formed in the prior art is effectively solved. The method effectively improves the continuity of construction operation and shortens the construction period.
As shown in fig. 2, 4 and 6, during the whole construction process, when the self-deformation tire type track construction vehicle meets other construction equipment such as a self-adaptive section engineering transport vehicle or a self-deformation tire type concrete construction vehicle or another self-deformation tire type track construction vehicle, the horizontal guide pipes on the two sides of the rack are controlled by the control cabinet to further extend outwards by the staff on the supporting platform of the self-deformation tire type track construction vehicle, so that the span under the rack is further increased, then the support pipes are controlled to extend out, the height under the rack is increased, and meanwhile, the walking device is controlled to deflect outwards, so that the walking device can run to the higher arc-shaped inner wall in the tunnel. Enough space is reserved below the self-deformation tire type track construction vehicle, and other construction equipment such as a self-adaptive section engineering transport vehicle, a self-deformation tire type concrete construction vehicle or another self-deformation tire type track construction vehicle can pass through the frame to complete vehicle crossing, so that the position conversion of the construction equipment in the tunnel is realized.
The construction method can be used for progressive one-way construction from one end of the tunnel to the other end of the tunnel, and can also be used for head-to-head two-way construction from two ends of the tunnel to the middle part in the tunnel.
The following specific examples are given by taking 150 m as the construction length of one work section:
in the first working day, the 300 m steel bar matrix is bundled and poured in the first working section and the second working section, so that a ballast bed matrix is formed on the base surface of the tunnel;
on the second working day, mounting a prefabricated roadbed with the length of 150 meters on the roadbed matrix of the first working section, and simultaneously binding and pouring a reinforcing steel bar matrix with the length of 150 meters in the third working section;
and in the third working day, 150 meters of steel rail is paved on the first working section, and 150 meters of prefabricated ballast bed installation and 150 meters of reinforcing steel bar matrix binding and pouring in the fourth working section are simultaneously carried out.
According to the construction period, 3 working days are needed for completing the laying of the steel rail with the length of 150 meters, and the laying of the steel rail with the length of 50 meters can be completed in each working day on average.
In actual construction, the steel bar matrix can be completely bundled and poured according to the example in the above example, and then the prefabricated track bed installation and the steel rail laying are sequentially performed on the steel bar matrix.
