Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
The embodiment of the utility model provides a: a sewage collecting device for cutting and dismantling a truss type combined arch bridge is shown in the attached figures 1-6 and comprises a plurality of suspension cross beams 1 which are arranged on the left side and the right side of a top plate of a solid section and are parallel to each other or a plurality of suspension cross beams 1 which are arranged on the left side and the right side of a lower chord top plate of other sections of an arch ring and are parallel to each other, when the top plate of the solid section needs to be cut, the suspension cross beams 1 are arranged on the top plate of the solid section, and when other sections need to be cut, the suspension cross beams 1 are arranged on the lower chord top plate of other sections. And suspension cross beams 1 are arranged on the left side and the right side of the top plate, the suspension cross beams 1 are parallel to the width direction of the bridge deck, and the head ends of the suspension cross beams extend to the outside of the bridge deck. The tail part of each suspension cross beam 1 penetrates through a plurality of fixed threaded steel bars 2, and the bottom ends of the fixed threaded steel bars 2 extend into the bridge body. When the suspension cross beam 1 is installed, a hole is drilled downwards from a top plate of a solid web section or a bottom chord top plate of other sections, then the suspension cross beam 1 is placed, and the suspension cross beam 1 penetrates through the suspension cross beam 1 through a fixing threaded steel bar 2 and then extends into the drilled hole, so that the suspension cross beam 1 is fixed. Each suspension cross beam 1 stretches out 1 and suspends threaded steel bar 3 in penetrating to the tip of the body of the bridge outside, suspend the top of the threaded steel bar 3 and suspend the cross beam 1 fixed connection, suspend the threaded steel bar 3 and stretch out to the vault top surface bottom or bridge bottom chord bottom downwards, suspend the bottom of the threaded steel bar 3 and link 5 on the top of the sewage collection box 4 and be connected. Thereby hanging the sewage collection tank 4 by hanging the threaded steel bar 3. In the installation process of the whole device, after the suspension cross beam 1 is fixed through the fixed threaded steel bars 2, the suspension threaded steel bars 3 penetrate and are fixed, and then the sewage collection box body 4 placed on the ground at the bottom of the bridge floor or on the water surface is lifted upwards through the lifting device, so that the fixed connection with the suspension threaded steel bars 3 is realized.
During the installation process, the suspension cross beam 1 should be installed on the uncut member outside the cutting line, so that the subsequent dismantling of the whole device is facilitated. And the head end of the sewage collection box body 4 extends forwards to be located below the cutting line, so that the sewage generated in the cutting process can drip into the sewage collection box body 4 along the cutting line. In the whole bridge cutting process, the bridge is divided into two parts from the middle of the main arch ring, and then the cutting is carried out in batches from the middle to two sides. After the cutting is finished, the device is disassembled and then is lifted and moved to the rear side for secondary installation.
The tail end of the sewage collection box body 4 is provided with a sewage outlet 6, the sewage outlet 6 can be used for being connected with a sewage discharge pipeline, and the sewage discharge pipeline can be fixed at the bottom of the bridge floor and extends into a drainage ditch of a shore base all the time, so that the sewage is discharged. Under the condition that the sewage draining outlet 6 is not arranged, the collected sewage can be pumped into the sewage transportation vehicle through the water suction pump. 4 tops of sewage collection box are fixed with protection guardrail 7 all around, and 4 tops of sewage collection box are connected at the head, the tail both ends and are fixed with many reinforcing bars 8 that are parallel to each other, are fixed with the support steel mesh 9 on the reinforcing bar 8.

And the two ends of the top of the suspension threaded steel bar 3 are fixed by the locking nuts 11, so that the suspension threaded steel bar 3 is fixedly connected with the suspension cross beam 1.
The sewage collection box 4 left and right both sides head, middle, tail end respectively are equipped with 1 rings 5, and the rings 5 of middle-end and tail end are respectively through 1 suspension rebar 3 rather than the suspension crossbeam 1 directly over being connected, and the rings 5 of head end are connected through hand-held block 12 and the suspension rebar 3 that middle-end rings 5 position corresponds, and the suspension rebar 3 bottom that middle-end rings 5 position corresponds also is provided with rings 5. The mounting and dismounting of the chain block 12 is much more convenient than the hanging of the twisted steel 3, so the head end is connected by using the chain block 12. The chain block 12 is not fully used for connection, and because the chain block 12 is a flexible member, if the sewage collection box 4 is hung by the chain block 12, the sewage collection box 4 can shake, which is very dangerous for constructors. And hanging in midair the twisted steel 3 and being the rigid member, can guarantee that sewage collection box 4 can not appear rocking.
The bottom end of the suspension threaded steel bar 3 penetrates through the top plate of the steel plate connecting box 13, 1 locking nut 11 is sleeved on each suspension threaded steel bar 3 at two ends of the top plate of the steel plate connecting box 13, a connecting shackle 14 is fixed at the bottom of the steel plate connecting box 13, and the connecting shackle 14 is connected with the hanging ring 5. The height of the steel plate connecting box 13 can be adjusted by adjusting the positions of the locking nuts 11 at the two ends of the top plate of the steel plate connecting box 13, so that the front height, the rear height, the left height and the right height of the whole sewage collecting box 4 are adjusted, and the sewage collecting box 4 is kept in a horizontal state. And the height of the whole sewage collection tank 4 is adjusted by the length of the suspension twisted steel 3. A quick connection to the hoist link 5 can be achieved by means of the connection shackle 14.
The end part of the suspension cross beam 1 extending out of the bridge body is provided with a safety ladder stand 15, and the bottom end of the safety ladder stand 15 is fixed at the top of the sewage collection box body 4. Be provided with safe cat ladder 15, make things convenient for operating personnel to go up and down.
When the suspension crossbeam 1 is installed on the lower chord top plate of other sections, because the lower chord top plate of the bridge is an arc surface, a supporting triangular steel plate 16 is welded at the bottom of the suspension crossbeam 1, and the supporting triangular steel plate 16 is fixedly connected with the lower chord top surface of the bridge in a welding manner, so that the suspension crossbeam 1 is kept in a horizontal state, and the suspension twisted steel 3 is convenient to install.
The cross section of the sewage collecting box body 4 is triangular, so that collected sewage is concentrated at the tail part of the sewage collecting box body 4 and is discharged through the sewage discharging port 6.
Welded fastening is equipped with a plurality of triangle steel sheet 17 around the sewage collection box 4 top, and the welding of every triangle steel sheet 17 department has 1 sleeve 18, and the welding is at the sewage collection box 4 top in sleeve 18 bottom, and the lateral wall then with triangle steel sheet 17 side welded fastening to make sleeve 18 firm in connection. The protective guardrail 7 is formed by fixedly connecting longitudinal, transverse and vertical steel pipes through connecting bolts, and the bottom of the vertical steel pipe of the protective guardrail 7 is inserted into the sleeve 18. Thereby realize the quick fixed of protection guardrail 7, it is also more convenient when dismantling.
