Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering construction technology, specifically relating to a support structure for erecting steel beams along a high slope channel for water conveyance steel pipes. Background Technology

[0002] Drinking water pipelines are pipelines that transport raw water from water sources to water treatment plants. Water sources often originate from mountainous river sections in the upper reaches of a river basin where human activity has minimal impact. Water treatment plants are typically built in the middle and lower reaches of rivers, near towns in relatively open areas. Many places in my country have irrigation canals similar to the "Red Flag Canal," which divert water along steep cliffs to farmland on plains. Due to factors such as the large drainage area controlled by the canal head, the numerous villages along the canal, complex confluence conditions, and the difficulty in enforcing strict drinking water source protection regulations, irrigation canals are unsuitable for transporting raw water for drinking water projects. Therefore, drinking water pipelines are frequently laid along high-slope irrigation canals.

[0003] Drinking water pipelines are laid along irrigation canals on high slopes, where large construction machinery cannot reach the site. All materials must be transported vertically by crane or manually moved up the slope. Furthermore, the design cross-section of the canal does not allow for the installation of tripods or other supports that could obstruct flow. Therefore, pipelines are mostly laid at the upper part of the canal cross-section. Steel beams offer advantages such as small cross-sectional dimensions, factory fabrication, centralized hoisting and installation, short construction time, and minimal impact on normal irrigation. Therefore, steel structures are generally chosen as the support beams for pipelines laid along irrigation canals on high slopes.

[0004] As mentioned above, when using steel structures (steel beams), it is necessary to excavate trenches on the mountain slope for support installation. When the mountain slope is downslope and relatively stable, stone trenches can be excavated to install the supports before erecting the steel structure, but this is extremely difficult. When the mountain slope is upslope and has poor stability, for safety reasons, the mountain slope needs to be reinforced first, then a safety shed needs to be built before excavating trenches to install the supports. Since upslope mountains can be tens or even hundreds of meters high, the reinforcement costs are enormous. Therefore, it is necessary to develop a support structure that does not require trenching for the installation of steel beams along high-slope channels for water conveyance steel pipes. Utility Model Content

[0005] The purpose of this utility model is to solve the problems of the prior art and provide a support structure for erecting steel beams along a high slope channel for water conveyance steel pipes.

[0006] To solve the technical problem, the technical solution of this utility model is: a support structure for erecting steel beams along a high slope channel for water conveyance steel pipes, characterized in that: it includes a movable support and a fixed support. The movable support is fixedly installed on the water-facing side of the channel, and the fixed support is fixedly installed on the mountain slope. The fixed support includes a steel plate structure, anchor rods, and expansion bolts. The anchor rods are anchored to the mountain slope, and one end of the anchor rods is fixedly connected to the steel plate structure. The expansion bolts are fixed to the mountain slope, and one end of the expansion bolts is also fixedly connected to the steel plate structure. The side of the steel plate structure away from the mountain slope is welded to the steel beam, and the other end of the steel beam is installed on the movable support. A water conveyance steel pipe is installed on the steel beam.

[0007] Preferably, there are two anchor rods and two expansion bolts, with the two anchor rods fixedly connected to the upper two ends of the steel plate structure and the two expansion bolts fixedly connected to the lower two ends of the steel plate structure.

[0008] Preferably, the length of the anchor rod is greater than the length of the expansion bolt, the angle between the straight line of the anchor rod and the straight line of the steel beam is 0~45°, and the straight line of the expansion bolt is parallel to the straight line of the steel beam.

[0009] Preferably, the steel plate structure includes a rectangular steel plate integrally welded together, a left angle steel, a right angle steel, and a lower angle steel. The left and right angle steels are respectively disposed on both sides of the same end face of the rectangular steel plate, and the lower angle steel is disposed on the rectangular steel plate below the left and right angle steels. Anchor bolt holes are respectively opened on the upper side of the welded parts of the left and right angle steels and the rectangular steel plate, and expansion bolt holes are respectively opened on both sides of the welded parts of the lower angle steel and the rectangular steel plate. One end of the anchor rod passes through the anchor bolt hole and is fixedly connected to the nut, and one end of the expansion bolt passes through the expansion bolt hole and is fixedly connected to the nut.

[0010] Preferably, the steel beam is an I-beam, with the lower horizontal surface of the I-beam placed on the plane of the lower angle steel and welded to the lower angle steel, and the upper horizontal surface of the I-beam welded to rectangular steel plates on both sides respectively.

[0011] Preferably, the movable support includes a lower pad, anchor bolts, an upper pad, a left rib, and a right rib. The upper pad is disposed on the upper surface of the lower pad. The upper and lower pads are fixed to the water-facing side of the channel by anchor bolts. The upper surface of the upper pad is welded to the steel beam. The left and right ribs are disposed on both sides of the steel beam and welded to the steel beam and the upper pad, respectively.

[0012] Preferably, the lower pad has four circular holes at its four corners, and the upper pad has four elliptical holes at its four corners.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] (1) This utility model discloses a support structure for erecting steel beams along a high slope channel for water conveyance steel pipes. The support for trenching construction is adjusted to a fixed support of steel plate structure + anchor rod + expansion bolt, which greatly reduces the amount of rock excavation for the support. Only the surface needs to be leveled, avoiding the impact of deep rock excavation on the slope stability. This avoids the overall reinforcement construction of the mountain before the support is constructed and the related costs, thus improving the construction progress and safety of the project.

[0015] (2) The fixed support of this utility model includes a steel plate structure, anchor rods and expansion bolts that are fixedly connected. The anchor rods are anchored to the mountain slope and the expansion bolts are fixed to the mountain slope. The fixed support provides support for the steel beam and strengthens the rock mass of the mountain slope, thereby improving the stability of the mountain slope.

[0016] (3) The length of the anchor rod of this utility model is greater than the length of the expansion bolt. Due to the larger length of the anchor rod, it has a certain reinforcement effect on the rock mass of the hillside. The angle between the straight line where the anchor rod is located and the straight line where the steel beam is located is 0~45°. The straight line where the expansion bolt is located is parallel to the straight line where the steel beam is located. The anchor rod and the expansion bolt play a fixing role for the fixed support, providing shear resistance and pull-out resistance, and resisting the vertical force and bending moment transmitted from the steel beam.

[0050] The working principle of this utility model is as follows:

[0051] like Figures 1-8As shown, this utility model discloses a support structure for erecting steel beams along a high-slope irrigation canal for water conveyance. A steel beam structure is used for erecting the pipeline along the high-slope irrigation canal. Movable supports 1 are installed on the water-facing side of the canal 6 where installation and maintenance are feasible, and fixed supports 2 are installed on the mountainside (mountain slope 7). The fixed supports 2 include a steel plate structure 2-1, anchor rods 2-2, and expansion bolts 2-3. The steel beams 3 and the steel plate structure 2-1 are connected by welding. The steel plate structure 2-1 consists of a rectangular steel plate and two sections of angle steel on both sides. The steel plate is welded to a section of angle steel to form a whole. The angle steel is used to increase the rigidity of the steel plate and increase the welding area with the steel beam. The steel plate structure 2-1 is fixed to the mountain slope 7 by nuts 5 through two anchor rods 2-2 and two expansion bolts 2-3. The anchor rods 2-2 and expansion bolts 2-3 play a fixing role for the entire fixed support 2, providing shear and pull-out resistance, resisting the vertical force and bending moment transmitted from the steel beam 3. At the same time, due to the large length of the anchor rods 2-2, they have a certain reinforcement effect on the rock mass of the mountain slope 7.

[0052] This utility model discloses a support structure for erecting steel beams along a high slope channel for water conveyance steel pipes. The support structure is adjusted from the trenching construction to a fixed support structure of steel plate structure + anchor rod + expansion bolts, which greatly reduces the amount of rock excavation work for the support. Only the surface needs to be leveled, avoiding the impact of deep rock excavation on slope stability. This avoids the need for overall mountain reinforcement construction and related costs before the support construction, and improves the construction progress and safety of the project.

[0053] This utility model's fixed support includes a fixedly connected steel plate structure, anchor rods, and expansion bolts. The anchor rods are anchored to the mountain slope, and the expansion bolts are fixed to the mountain slope. The fixed support provides support for the steel beam while reinforcing the mountain slope rock mass, thereby improving the stability of the mountain slope.

[0054] The length of the anchor rod of this utility model is greater than the length of the expansion bolt. Due to the larger length of the anchor rod, it has a certain reinforcement effect on the hillside rock mass. The angle between the straight line where the anchor rod is located and the straight line where the steel beam is located is 0~45°. The straight line where the expansion bolt is located is parallel to the straight line where the steel beam is located. The anchor rod and the expansion bolt play a fixing role for the fixed support, providing shear resistance and pull-out resistance, and resisting the vertical force and bending moment transmitted from the steel beam.

[0055] The specific installation process of this utility model is as follows:

[0056] 1. Fabrication and processing of steel structures, including steel beams 3 and supports (movable support 1 and fixed support 2);

[0057] 2. Determine the location of steel beam 3, implement temporary protection against falling rocks, construct movable support 1, and level the installation surface of fixed support 2 (level the working surface).
