An integrated structure and construction method for the wall of a water intake pump house

Abstract

The present invention provides an integrated structure and construction method for the wall of a water intake pump house, belonging to the technical field of prefabricated buildings. It includes columns buried in the ground, with vertical grooves formed on the columns. At the bottom of the vertical grooves, there are a first bladder and a second bladder. A barrier part is arranged between the first bladder and the second bladder. The first bladder and the second bladder are filled with a first liquid and a second liquid respectively. After the barrier part ruptures, the first liquid and the second liquid are mixed to generate expansion gas. On the side surface of the wall, there is a matching groove, and on both sides of the matching groove, there are protruding abutting edges. The abutting edges squeeze the first bladder and the second bladder, causing the barrier part to rupture. The shape of the first bladder and the second bladder after being connected and expanded is adapted to the shape of the matching groove. In the present invention, the liquids in the first bladder and the second bladder are mixed to generate expansion gas. By using the expanded first bladder and second bladder to abut against the side surface of the wall, the gap between the wall and the column is reduced, improving the sealing and heat preservation performance of the water intake pump house.

The wall 30 is arranged between the two columns 10, and the edges of the wall 30 are respectively in contact with the column 10 and the base 20. After the column 10, the base 20, and the wall 30 are spliced, they form a water intake pump house building.

[0041] Refer to Figure 2 , the number of columns 10 is multiple, and the multiple columns 10 are respectively located at the corner positions of the water intake pump house. The column 10 protrudes from the ground, and a vertical groove 11 is opened on the side at a preset height position from the ground. The vertical groove 11 is opened along the length direction of the column 10. A vertical groove 11 is opened on each different side of the column 10. When the sides of the column 10 are respectively connected to two walls 30, a vertical groove 11 is respectively opened in two of the sides of the column 10; when the sides of the column 10 are respectively connected to three walls 30, a vertical groove 11 is respectively opened in three of the sides of the column 10. A vertical through hole 12 is opened through the groove wall of the vertical groove 11 along the horizontal direction, and the vertical through hole 12 is a waist-shaped hole. A hook rod 13 protrudes from the side of the column 10 at the position protruding from the ground.
