Description

Technical Field

[0001] The utility model relates to the technical field of large-scale water conservancy projects, in particular to an installation structure of a pre-buried base of a horizontal tubular pump. Background Art

[0002] The existing embedded base installation structure is as follows Figure 1 Described, it comprises a pre-embedded base 1 and a reserved installation opening 2, the reserved installation opening 2 is opened in the pump room wall 3 cast by prefabricated concrete, the pre-embedded base 1 is installed in the reserved installation opening 2, the pre-embedded base 1 is a truncated cone-shaped cylinder, and the pump room wall 3 is cast with protruding steel bars, and the protruding ends of the protruding steel bars extend into the reserved installation opening 2; a circle of anchor bolts 4 are evenly arranged on the outer wall of the pre-embedded base 1 through bolt holes, and the anchor bolts 4 are respectively welded to the protruding steel bars. After the pre-embedded base 1 and the protruding steel bars are welded, they are fixed in the reserved installation opening 2 by pouring the second phase of concrete.

[0003] This embedded seat installation structure requires the embedded base to be hoisted from the horizontal direction and pushed horizontally into the reserved installation opening when installing the embedded base. The hoisting installation is difficult, and the installation position cannot be fine-tuned after hoisting to the specified position. The bottom of the embedded base is an arc, which is easy to roll during installation, resulting in inconvenience in installation and adjustment. There is a gap between the bolt holes of the anchor bolts and the embedded base, which is easy to loosen. Therefore, it is necessary to first fix a circle of anchor bolts in the reserved installation opening by pouring concrete or welding protruding steel bars, and then install the embedded base on the anchor bolts, resulting in a complicated and difficult installation process. Before pouring the second phase of concrete, the embedded base was only fixed by welding the protruding steel bars, which was not firmly fixed. During the pouring of the second phase of concrete, the embedded base was prone to displacement. Summary of the invention

[0004] In view of the shortcomings of the existing installation structure of the embedded base of the horizontal cross-flow pump, such as the complex and difficult installation process, the inability to fine-tune the position, and the loose fixation, which causes the embedded base to be displaced during the pouring process, the utility model provides an installation structure of the embedded base of the horizontal cross-flow pump, which is easy to install, can fine-tune the position, is firmly fixed, and will not be displaced during the pouring process.

[0016] See Figures 2 to 4 , an installation structure of a pre-embedded base of a horizontal through-flow pump, which includes a pre-embedded base 1 and a reserved installation opening 2. The reserved installation opening 2 is opened in a pump room wall 3 cast with prefabricated concrete. The pre-embedded base 1 is installed in the reserved installation opening 2. The pre-embedded base 1 is a truncated cone-shaped cylinder. An extended steel bar 8 is cast in the pump room wall 3. The extended end of the extended steel bar 8 extends into the reserved installation opening 2. The top of the reserved installation opening 2 passes through the pump room floor. The pre-embedded base 1 can be vertically hoisted into the reserved installation opening 2, avoiding the lateral movement and pushing of the pre-embedded base 1, reducing the difficulty of hoisting and installation, and simplifying the installation process. A circle of anchor hooks 5 are evenly welded on the outer wall of the pre-embedded base 1. There are 12 anchor hooks 5 in the figure. After welding, there is no need to reinforce each anchor hook 5 separately, which further simplifies the installation process. The four anchor hooks 5 at the four corners are respectively connected to one end of the basket bolt 9, and the other end of the basket bolt 9 is connected to the protruding steel bar 8. The basket bolt 9 is retractable, and the position of the embedded base 1 can be fine-tuned by adjusting the length of the basket bolt 9. After the basket bolt 9 is tightened, it can also play a tightening and fixing role to ensure that the embedded base 1 does not move when pouring the second phase concrete.

[0017] The anchor hooks 5 are welded with the protruding steel bars 8 respectively. The number and direction of the protruding steel bars 8 welded by the anchor hooks 5 are determined by the specific construction conditions. In the figure, one protruding steel bar 8 is welded for each anchor hook 5. A support block 7 with a flat bottom surface is provided at the bottom of the embedded base 1, and an adjustment pad 6 is installed under the support block; the support block can prevent the embedded base 1 from rolling, which is convenient for installation and position adjustment. After the embedded base 1 is adjusted and the protruding steel bars 8 are welded, they are fixed in the reserved installation opening 2 by pouring the second phase concrete.

[0018] See Figure 5 The adjustment shim 6 includes a base 61 and a slider 62. One side of the base 61 is an inclined surface, and the other side is equipped with an adjusting bolt 63. The slider 62 can slide on the inclined surface, and one end of the slider 62 is threadedly connected to the adjusting bolt 63. By turning the adjusting bolt 63, the position of the slider on the inclined surface can be changed, thereby changing the height of the adjustment shim 6 and fine-tuning the height position of the embedded base 1.

[0019] The cylinder wall of the embedded base 1 is provided with a plurality of concrete exhaust holes 10, which are convenient for exhausting when pouring the second phase concrete to ensure that the concrete is poured solidly. After the second phase concrete is poured, a sealing cover is welded on the concrete exhaust port 10 to ensure the sealing effect and prevent water seepage.

[0020] The installation process is as follows: vertically hoist the embedded base 1 from above the pump room into the reserved installation opening 2, support the support block 7 on the adjustment pad 6, fine-tune the adjustment bolt 63 to keep the center height of the embedded base 1 consistent with the center line height of the water pump unit, use the basket bolt 9 to connect the four anchor hooks 5 and the protruding steel bar 5 in the four corners, adjust the basket bolt 9 to make the center line of the embedded base 1 coincide with the center line of the water pump unit, and then weld each anchor hook 5 to the protruding steel bar 5. If the position of the embedded base 1 is offset during or after welding, continue to adjust the basket bolt 9. After completing the position adjustment and welding, pour the second phase of concrete to complete the installation.
