Problems solved by technology

[0004] The purpose of the present invention is: when the formwork of upper roof 1 is erected by scaffolding in the prior art, after the upper roof 1 is poured, the scaffolding cannot be taken out from the grid space 3, so the scaffolding of this method cannot be reused and wastes materials , Moreover, it takes a long time to set up the scaffolding, which increases the construction time of the immersed tube roof and increases the construction cost. A construction method for the roof of the sealed space at the top of the immersed tube is provided

Embodiment 1

[0039] like Figure 2-4 As shown, a construction method for the top plate of the sealed space at the top of the immersed tube includes the following steps:

[0040] S1. pouring the side wall 4, and pre-embedding a connector 41 on the side wall 4, and the connector 41 is located on the upper part of the side wall 4;

[0041] S2. Make the support structure 5, and connect the support structure 5 with the connector 41, so that the support structure 5 is located in the lattice space 3;

[0042] S3. construct the bottom mold 11 for pouring the upper roof 1 on the support structure 5, and use the support structure 5 to support the bottom mold 11;

[0043] S4. The top mold 12 is constructed above the bottom mold 11, so that a pouring space for forming the upper top plate 1 is formed between the bottom mold 11 and the top mold 12;

[0044] S5. The upper roof 1 is formed by pouring.

[0045] In the above solution, the support structure 5 is connected with the connecting member 41 in ...

Embodiment 2

[0050] like Figure 5 and 6As shown, in the construction method for the top plate of the sealed space at the top of the immersed tube described in this embodiment, the middle of the bottom mold 11 is in a suspended state, so the gravitational bending moment of the bottom mold 11 increases continuously from the middle to the two ends. Therefore, the difference between the solution of this embodiment and the embodiment 1 is that the bottom mold 11 includes a horizontally arranged support plate 13, and the bottom of the support plate 13 is provided with an arch part 14, and the arch part 14 is One end is connected to one of the supporting structures 5 , the other end is connected to the supporting structure 5 on the opposite side wall 4 , and the arched member 14 is supported and connected to the supporting plate 13 .

[0051] On the basis of the above, in a further preferred manner, the arched member 14 is a space truss structure, so that under the same strength, the structural...

Embodiment 3

[0054] like Figure 4 and 6 As shown, the construction method for the top plate of the sealed space at the top of the immersed tube described in this embodiment is different from Embodiment 1 or 2 in that the support structure 5 includes a base 51, and the base 51 is provided with There is a lifting mechanism 52, and the top of the lifting mechanism 52 is connected with a support table 53 for supporting the bottom mold 11;

[0055] The step S3. constructing the bottom mold 11 for pouring the upper roof 1 on the support structure 5, and using the support structure 5 to support the bottom mold 11, specifically:

[0056] S31. construct the bottom mold 11 for pouring the upper roof 1 on the support structure 5;

[0057] S32. Place the bottom mold 11 on the support table 53;

[0058] S33. Adjust the lifting mechanism 52 to make the bottom mold 11 reach a predetermined height.

[0059] The beneficial effect of this embodiment is that the position and height of the support table ...

Abstract

The present invention relates to the field of immersed tubes, in particular to a construction method for the roof of the sealed space at the top of the immersed tube, comprising the following steps: S1. Pouring side walls, and pre-embed connectors on the side walls, the connectors are located on the upper part of the side walls ; S2. Make the support structure, and connect the support structure with the connectors, so that the support structure is located in the grid space; S3. Construct the bottom form for pouring the upper roof on the support structure, and use the support structure to support the bottom form ; S4. Constructing a top mold above the bottom mold, so that a pouring space for forming the upper roof is formed between the bottom mold and the top mold; S5. Pouring and forming the upper roof. A construction method of the present application for the roof of the sealed space at the top of the immersed tube uses materials, production and installation costs, and time costs far less than scaffolding, thereby saving materials, shortening the corresponding construction time, and reducing construction costs.

Description

technical field [0001] The invention relates to the field of immersed pipes, in particular to a construction method for a roof plate of a sealed space at the top of an immersed pipe. Background technique [0002] like figure 1 As shown in the figure, when prefabricating the immersed tube structure, in some parts, in order to reduce the gravity load of the upper part of the immersed tube, it is necessary to require its strength to meet the requirements of use, and also to take into account the waterproof requirements, so it is necessary to prefabricate the top plate of the immersed tube into at least two layers The lattice structure, and there will be a lattice space 3 between the upper roof 1 and the lower roof 2, and the side walls around the lattice space 3 and the upper roof 1 and the lower roof 2 are mutually sealed and set, so that the lattice space 3 form a sealed space. [0003] As for the construction of the above-mentioned upper roof 1, due to the large height dif...
