Embodiment 1

[0047] Such as Figure 1-9 As shown, the up-ramp demolition system includes the temporary buttress system erected at the bottom of the box girder 3 of the up-ramp, and the construction enclosure 26 spraying system located on the periphery of the construction area, wherein the up-ramp needs to be dismantled during the demolition process. Pavement layer, remove the guardrails and flange plates 2 on both sides, and then remove the box body of the continuous box girder 3 and the pier column 5, the support 4 between the pier column 5 and the continuous box girder 3, etc.

[0048] The temporary pier system includes a steel pipe support 20 and a support foundation 21, wherein the steel pipe support 20 includes a main beam 11, a distribution beam 10 located at the top of the main beam 11, a steel pipe column 14 located at the bottom of the main beam 11 and two The high-strength tension bolts 13 between the steel pipe columns 14 are used to fix two adjacent steel pipe columns 14 throug...

Embodiment 2

[0055] The construction method of the up-ramp demolition system uses the above-mentioned up-ramp dismantling system to dismantle the up-ramp, specifically including the following steps:

[0056] S000, construction enclosure 26 sprinkler system installation:

[0057] S001. Transport the fence column 25 and fence 26 manufactured in advance in the factory to the construction area for assembly to form the construction fence 26. Both the fence 26 and the movable fence 31 are made of steel plates at the bottom and steel wire mesh at the top manufactured;

[0058] S002. According to the construction requirements, a temporary opening 29 is set on the construction fence 26. After the position of the temporary opening 29 is selected, the door frame 30 is welded on the inner side of the top of the fence column 25 on both sides of the position, and the bottom of the door frame 30 is fixed with an anchor bolt 16 On the ground, weld the rail clamp 34 on the downward surface of the door fra...

Abstract

The invention relates to an ascending ramp dismantling system and a construction method thereof. According to the scheme, the ascending ramp dismantling system comprises a temporary buttress system and a construction fence spraying system; the temporary buttress system comprises a steel pipe support and a support foundation. The steel pipe support comprises a main beam, a distribution beam, steel pipe stand columns and high-strength split bolts. The support foundation comprises a foundation longitudinal beam with the top connected with the steel pipe stand column and a longitudinal beam sleeper fixed to the bottom of the foundation longitudinal beam through a connecting part, and the foundation longitudinal beam is fixed to the bearing platform through an anchor bolt. The construction fence spraying system comprises fence stand columns fixed to the ground, fences arranged between every two adjacent fence stand columns and pipelines arranged at the tops of the fence stand columns and the fences. The fence stand columns and the fence form a circle of construction fence, and a temporary opening is formed in any side of the construction fence. A plurality of water mist nozzles facing the interior of the construction fence are arranged on the pipeline. The construction method has the advantages that the dismantling difficulty and the dismantling cost are reduced, the construction period is shortened, and accumulated water pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to an up ramp demolition system and a construction method thereof. Background technique [0002] The ramp is an indispensable part of the interchange, and it is a road for up and down intersecting. Whether the design of the ramp is reasonable or not is directly related to the function of the interchange, the safe and smooth driving, the economy of operation and the investment of the project. However, with the process of urbanization, the road traffic network is becoming more and more complex. In the reconstruction and expansion project of the original expressway, it is inevitable to involve the demolition and construction of the existing up-ramp. [0003] At present, the demolition construction of the up ramp usually adopts the closed enclosure construction of the whole line. Firstly, the pavement layer of the bridge deck is removed, the guardrails and flange plate...
