Description

Technical Field

[0001] This invention belongs to the field of water conservancy and hydropower engineering construction technology, specifically relating to a method for simultaneous construction of gate slot installation and concrete pouring. Background Technology

[0002] Currently, in the field of water conservancy and hydropower engineering, gate slot installation and concrete pouring are carried out in separate steps. Generally, after the first phase of the main concrete pouring is completed, the work is handed over to the metal structure department to begin gate slot installation. The main concrete pouring work in water conservancy projects is generally large, occupying a significant portion of the linear construction period and greatly impacting the construction progress. Concrete pouring requires the erection of a full-span scaffold as a formwork support system. During concrete pouring, the construction scaffolding must be inserted deep into the gate slot openings; the gate slots cannot be installed until the scaffolding is dismantled. This results in two separate erections and dismantlings of the construction scaffolding from the start of concrete pouring to the completion of the second phase of concrete pouring. This construction method achieves self-stabilization of the formwork using tie rods, eliminating the need for scaffolding support. Only a temporary scaffolding needs to be erected, allowing the gate slot hoisting to be carried out simultaneously during the first phase of concrete pouring. This enables simultaneous construction of gate slot installation and concrete pouring, accelerating the construction progress, reducing project costs, and improving production efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method that achieves self-stabilization of the template by means of tie rods, without relying on the support of the construction scaffold, and only requires the construction of a worker's scaffold to enable the simultaneous hoisting of the gate slot during the first phase of concrete pouring, thereby realizing the simultaneous construction of gate slot installation and concrete pouring.

[0004] The technical solution of the present invention is: a method for simultaneous construction of door slot installation and concrete pouring, comprising the following steps:

[0005] Step 1: Pour the first-stage concrete base slab. After the pouring is completed, hoist the sill onto the concrete base slab for installation. After the sill is installed, pour the second-stage concrete for the sill.

[0006] Step 2: After the second phase of concrete pouring for the bottom sill is completed, a scaffolding is erected above the bottom sill.

[0007] Step 3: Erect template panels on both sides of the tower body, and install a tie rod at intervals between the template panels on both sides of the tower body;

[0008] Step 4: Install bolts at both ends of the tie rod and adjust the bolts to make the two template panels and the tie rod form a stable whole;

[0009] Step 5: When the tower body is poured to a height higher than the length of a single section of the main rail and the counter rail and reaches the demolding strength, loosen the bolts on both sides of the template panel, move the entire template vertically upward to the next pouring position, adjust the bolts to reinforce the entire template and pour concrete.

[0010] Step 6: When the concrete is poured to the position above the lintel, hoist the main rail, reverse rail and lintel to the position where the tower body is poured. Use the reinforcing bars reserved in the first phase of pouring to fix the main rail and reverse rail. Set up an isolation platform at the upper position of the lintel. Install the door groove at the lower part of the isolation platform. Set up a construction scaffold on the upper part of the isolation platform to continue the tower body concrete pouring work.

[0011] Step 7: After the concrete above the lintel is poured, install the remaining door slots and pour the second phase of concrete.

[0012] Furthermore, the pouring of the tower body is carried out simultaneously with the installation of the main rail, reverse rail, lintel, and auxiliary rail until the door slot is installed. After the main rail, reverse rail, auxiliary rail, and lintel are installed, the second phase of concrete pouring is carried out.

[0013] The beneficial effects of this invention are as follows: The concrete pouring formwork structure of the method for simultaneous installation of door slots and concrete pouring is simple and easy to assemble. The formwork can be stabilized and disassembled simply by adjusting the bolts on both sides of the tie rods, eliminating the need for a formwork support system and improving construction efficiency. Furthermore, by re-erecting the construction scaffold for door slot installation after the installation of the door slot sill and the second-stage concrete pouring, the construction scaffold only requires one erection and dismantling process, further improving construction efficiency. In summary, this method for simultaneous installation of door slots and concrete pouring avoids the situation where the door slot embedded parts can only be installed after the main concrete pouring is completed, achieving simultaneous implementation of door slot installation and concrete pouring, significantly improving construction efficiency.
