Embodiment 1

[0049] (1) laying plain concrete cushion 1, described plain concrete cushion 1 is a back-shaped structure, wherein the elevation of the cushion of the mouth-shaped position of the inner ring is higher than the elevation of the cushion of the mouth-shaped position of the outer ring;

[0050] (2) A base plate deformation joint 10 is set in the transverse middle part of the cushion layer 1. The construction method of the base plate deformation joint 10 is as follows: install the lower end low-foaming polystyrene in sequence from bottom to top at the set base plate deformation joint 10 position. An ethylene caulking board, a rubber waterstop and an upper low-foaming polyethylene caulking board, the top level of the upper low-foaming polyethylene caulking board is higher than the top level of the reinforced concrete bottom plate 2 to be poured.

[0051] (3) Reserve a base plate reserved belt at the longitudinal middle part of the cushion layer 1 on both sides of the base plate defor...

Abstract

The invention discloses a construction method for a guide wall of a clean water tank. The construction method comprises the following steps: paving a plain concrete cushion layer which is shaped like a dual rectangular shape; casting a reinforced concrete bottom plate; preserving a tank wall reinforcing band in the position, which corresponds to a bottom plate preservation band, on the wall of the clean water tank, and respectively casting clean water tank wall concrete at the periphery of the reinforced concrete bottom plate, two sides of a tank wall deformation joint and two sides of the tank wall reinforcing band; separately casting multiple special struts on the reinforced concrete bottom plate; casting clean water tank top plates at the top of the clean water tank wall and the tops of the special struts; performing primary positioning, plumbing and repositioning on a set guide wall position by use of a measuring and positioning method combined with a laser plummet, a theodolite and a total station, releasing a measurement line position of the guide wall, laying guide walls between two adjacent special struts at set positions to form multiple rows of guide walls. By virtue of the method, influences of factors such as artificial errors and measurement errors are reduced.

Description

technical field [0001] The invention relates to the field of water purification plants, in particular to a construction method for diversion walls of clear water pools in building water purification plants Background technique [0002] The clean water pool is an important single project in the water purification plant project, and it will store a large amount of water in future use. For the diversion wall, diversion and diversion of excessive drinking water will be the top priority. Therefore, when constructing the diversion wall of the clear water pool, it is particularly important to ensure the firmness of the diversion wall and the accuracy of diversion. [0003] 1 The Chinese patent application number 2013101211664 discloses a "short-range high-efficiency advection sedimentation tank". The present invention discloses a short-range high-efficiency advection sedimentation tank, which is characterized in that the horizontal corridor type flocculation zone and the A-type pl...
