Description

Technical Field

[0001] The utility model belongs to the technical field of concrete pouring construction in arch ribs of arch bridges, and in particular relates to a channel structure suitable for installing a pipe-pressure concrete pump pipe. Background Art

[0002] A super-large bridge refers to a bridge with a total span of more than 1000m or a single span of more than 150m. Due to the large span, it is difficult to build. Take the Shuangbao super-large bridge as an example. The Shuangbao super-large bridge is located between mountains and valleys. The terrain is steep. It continuously crosses the Dadong River and the small river ditch. The transportation is inconvenient and the construction is difficult. The calculated span of a single arch is 380m (the upper structure is 405m), the rise is 80m, and the rise-span ratio is 1 / 4.75; the arch axis adopts a catenary, and the arch axis coefficient is 1.55. The main arch ring adopts a variable-height space truss of steel tube concrete, a four-limb lattice structure, a tube diameter of 1.4m, and the tube is filled with C70 self-compacting micro-expansive concrete.

[0003] As Shuangbao Bridge is located in a steep terrain and is the world's largest cross-border double-arch bridge, high-altitude operations are extremely dangerous. The main arch ring adopts a variable-height space truss of steel tube concrete and a four-limb lattice structure, which results in the arch rib grouting holes being arranged at 90° to the pump pipe, thus placing higher requirements on the installation of the concrete delivery pump pipe, in order to improve the installation efficiency while ensuring the safety and stability of the pump pipe. Utility Model Content

[0004] The purpose of the utility model is to provide a channel structure suitable for installing a pipe pressure concrete pump pipe, so as to overcome the above-mentioned technical problems existing in the prior art.

[0005] To this end, the technical solution provided by the utility model is as follows:

[0006] A channel structure suitable for installing a pipe-pressure concrete pump pipe comprises a vertical channel, a transverse channel and a pump pipe fixing device. The vertical channel and the transverse channel are perpendicular and fixedly connected. The pump pipe fixing device is fixedly arranged at one end of the vertical channel close to the transverse channel.

[0007] The vertical channel includes a bottom support system and a vertical channel guardrail, and the vertical channel guardrail is fixed on the bottom support system and the two are perpendicular.

[0008] The transverse channel comprises a turning channel ladder beam and a transverse channel guardrail. The transverse channel guardrail is arranged on the top of the turning channel ladder beam. A turning channel pedal is arranged between the turning channel ladder beams.

[0009] The pump pipe fixing device includes a U-shaped card and a U-shaped card closing steel plate. The U-shaped card closing steel plate is arranged at the opening of the U-shaped card. The lower end of the U-shaped card is connected to the bottom support system. A pad is arranged in the U-shaped card. The pad is used to support the concrete pump pipe. A rubber pad is arranged between the concrete pump pipe and the U-shaped card closing steel plate.

[0010] The bottom support system includes a bottom transverse load-bearing beam, a ladder beam and steps. The ladder beam is fixed on the top of the bottom transverse load-bearing beam and the two are perpendicular. The vertical channel guardrail is fixed on the ladder beam and the two are perpendicular. The ladder beams are divided into two groups, and the steps are divided into multiple groups and are evenly spaced between the two groups of ladder beams.

[0011] The vertical channel guardrail includes a vertical pole and a horizontal pole. The vertical pole is arranged in several groups at equal distances along the ladder beam, and the horizontal pole is arranged in at least two groups at equal distances from top to bottom.

[0012] The beneficial effects of the utility model are:

[0013] The channel structure suitable for installing a pipe-pressure concrete pump pipe provided by the utility model is adapted to the 90° arrangement of the arch rib grouting holes and the pump pipe through the vertically arranged vertical channels and transverse channels, thereby meeting the concrete pump pipe installation requirements of super-large bridges.

[0014] The vertical channel of the channel structure supports the vertical channel guardrail through the bottom support system, and the transverse channel is connected to the transverse channel guardrail through the turning channel ladder beam. One end of the turning channel ladder beam is connected to the arch rib chord tube, and the other end is connected to one end of the ladder beam of the vertical channel. It is not only easy to install, but also has high safety and stability in installing the pump pipe.

[0015] The utility model provides steps and turning channel pedals in the vertical channel and the horizontal channel respectively, which not only supports the pump pipe, but also makes it convenient for construction workers to sprinkle water for cooling and avoid "pipe blocking" when pouring pipe-pressure concrete, because the arch rib will generate a lot of heat when pouring pipe-pressure concrete. High temperature has a great influence on the performance of concrete. It is convenient for construction workers to check the status of the pump pipe when pouring pipe-pressure concrete.

[0032] like Figure 3 As shown, in this embodiment, two groups of turning channel ladder beams 10 are arranged at equal distances. Since the pump pipe 9 is installed on the arch rib, one end of the turning channel ladder beam 10 is connected to the arch rib chord tube 13, and the other end is connected to one end of the ladder beam 4 of the vertical channel, and the turning channel ladder is arranged on the arch rib flat connecting tube 12.

[0033] Among them, the horizontal channel guardrail includes two vertical poles 8 and two horizontal poles 7. The vertical poles 8 are arranged in two groups at equal distances, and the horizontal pole 7 is arranged in one group, which is arranged at the top of the vertical pole 5.
