[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0019] Example: Figure 1-3The illustrated embodiment shows a formwork support system for an ultra-thick barite concrete shear wall with embedded large steel plates, wherein the shear wall comprises a 3.4m thick wall and a 2.6m thick wall.

[0020] Among them, Figure 2 The formwork support system of the 3.4m thick wall includes several No. 16 channel steels 2 located on both sides of the steel plate 1, several tension screws 3 located on both sides of the steel plate 1, and several adjustable rigid supports 4 located on one side of the steel plate 1. The channel steel 2 is arranged along the entire length of the 3.4m thick wall and buried 750mm below the raft surface. The inner side of the tension screw 3 is fully welded to the channel steel 2, and the outer side of the tension screw 3 is connected to the formwork 6. The outer end of the tension screw 3 on one side is connected to the raft 5 through the adjustable rigid support 4. The formwork 6 is made of veneer plywood, the secondary ribs are made of 100mm×100mm wooden squares, and the main ribs are made of 48.3mm×3.2mm double steel pipes.

[0021] like Figure 3 As shown, the formwork support system of the 2.6 m thick wall includes a plurality of adjustable rigid supports 4 located on both sides of the steel plate 1 , and the outer end of the formwork 6 is connected to the raft 5 through the adjustable rigid supports 4 .

[0022] When the embedded large steel plate ultra-thick barite concrete shear wall formwork support system is used in specific applications, the construction method includes: firstly, establishing a plane control network, releasing the shear wall line and the channel steel point through the plane control network, and in the process of tying the raft slab reinforcement: in the 3.4m thick wall, channel steel is set within the steel plate range and embedded in the raft slab reinforcement before pouring the raft slab concrete, after the wall reinforcement is tied, the wall within the steel plate range is reinforced by welding one end of the tension screw to the channel steel and using a reinforcement piece at the other end; no channel steel is set in the 2.6m wall, and after the wall reinforcement is tied, the wall formwork is reinforced by using a diagonal brace reinforcement method, and finally the barite concrete is poured.

[0023] (1) Before the construction of raft reinforcement, a plane control network is established. Through precise positioning, No. 16 channel steel is embedded in the 3.4m thick wall. The embedded depth of the channel steel is 750mm and the embedded spacing of the channel steel is 500mm×200mm. No. 16 channel steel is set at the supporting feet of the single-sided support and double-sided support. The depth of the embedded concrete is not less than 500mm and the extended length is 200mm.

[0024] (2) After the shear wall reinforcement is tied, the shear wall formwork is constructed. The formwork used is 18mm facing plywood, the secondary ribs are 100mm×100mm wooden squares, the main ribs are 48.3×3.2 double steel pipes, and the tension screws are M16 screws. To ensure the radiation protection performance of the wall, the screws are disposable measures. No plastic sleeves are set during construction. When removing the formwork, the screw heads outside the wall are directly cut off.

[0025] (3) The formwork method for the 3.4m thick wall is as follows: a single-sided tension formwork method is set on both sides of the shear wall within the steel plate range. The M16 screws are fully welded to the back of the channel steel on both sides. In order to ensure the integrity of the wall formwork, a single-sided support method is set on one side. The support rod is an adjustable steel support.

[0026] (4) The formwork method for the 2.6 m thick wall is as follows: a single-sided support formwork system is set up on both sides of the wall, and the support rods are adjustable steel supports.
