Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete pouring, in particular to a pouring template. Background Art
[0002] As water pollution caused by traditional printing and dyeing or chemical industries gradually becomes more serious, the planning and construction of sewage treatment plants are increasingly valued by local government agencies and construction units. As a key construction category of municipal engineering, sewage treatment plants have many technical difficulties such as construction technology, structure maintenance, and equipment maintenance. Among them, the construction technology of tall and thin-walled pool structures in sewage treatment plants has always been a construction difficulty of municipal engineering.
[0003] The functions of various treatment tanks in sewage treatment plants are different. The internal structures are usually separated by partition walls. In addition, the construction area occupied by a single tank itself is limited, which results in the partition walls being often high and thin. After the wall reinforcement is tied and the wall formwork is erected, when pouring concrete from above, the pumping port of the pump truck is blocked outside the formwork by the complex and staggered steel bars, making it difficult to pump concrete to the bottom of the wall, making it difficult to fully pour the concrete at the bottom of the wall and unable to complete the vibration. This causes gaps and holes in the wall parts that are not fully poured and vibrated, and fails to meet the requirements of the tank body for anti-seepage and anti-cracking. Utility Model Content

[0030] The construction process includes the following steps:
[0031] Step 1. In actual construction, the construction of the cushion layer 11 and the raft foundation 12 is first completed on site. After the steel bars of the tall and thin-walled wall are tied and the wall formwork 10 is installed, the casting formwork is installed. First, the fixed plate 1 is installed on the outer surface of the wall. Each fixed plate 1 is fixed with two of the above-mentioned installation components. The fixed plate 1 is installed on the wall formwork 10 by means of tie rod bolts 41, and pads are used to relieve the pressure.
[0032] Step 2: Arrange an appropriate number of casting formworks based on the actual wall height. The specific number of arrangements needs to refer to the overall height of the wall. For walls that are too high, the casting formworks can be evenly installed in the middle of the wall.
[0033] Step three, after installation, check the firmness and stability of the formwork, and deliver the concrete slurry from the pumping port of the pumping truck to the casting formwork position. The first position to be poured is the bottom of the wall, and the pumping port is aligned with the hopper 3 for discharging. During the discharging process, always pay attention to whether the hopper 3 is blocked or overflowing, and clean it manually in time.
[0034] Step 4: After the pouring formwork of a single part is poured to 80%, the pouring position is changed and the next hopper 3 is poured. At the same time, a vibrating rod is inserted into the hopper 3 at the previous pouring position to vibrate the concrete poured at the bottom, and the pouring is carried out in the same way.
[0035] Step 5. After the concrete pouring on the same horizontal plane is completed, the vertical partition 6 on the fixed plate 1 is promptly cut vertically through the gripping rod 71 to seal the injection port 2 on the fixed plate 1, and the wall concrete and the concrete in the material holding port are separated to prevent the concrete at the injection port 2 from gradually hardening and causing demoulding difficulties. At the same time, the flatness of the concrete wall at the corresponding pouring position is maintained, and the concrete at the lower part of the wall is fully vibrated.

At the same time, the flatness of the concrete wall at the corresponding pouring position is maintained, and the concrete at the lower part of the wall is fully vibrated.
