Description

Technical Field

[0001] The utility model relates to a construction structure for supporting and jacking a shaft wall formwork, belonging to the technical field of construction. Background Art

[0002] When laying sewage pipes underground, the pipe jacking construction method needs to be adopted to avoid excavation working surfaces. Pipe jacking construction requires the construction of working wells, receiving wells and other shafts. When constructing the shafts, steel formworks need to be installed on one side of the soil mass to pour the retaining wall layer, and the steel formworks on one side of the soil mass need to be supported during pouring.

[0003] The existing support on one side of the soil mass can be seen in Chinese Patent Publication No. CN206722404U. Although the formwork system can be supported by a horizontal triangular truss system, the inclined support rod, adjusting support rod and fixed support rod in the horizontal triangular truss system are connected by welding or bolts, resulting in inconvenient adjustment to adapt the support to the formwork. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a construction structure for supporting and jacking a shaft wall formwork.

[0005] The utility model is achieved through the following technical solutions.

[0010] It also includes the soil layer on the side of the shaft and the rock stratum at the bottom of the shaft.

[0011] The rock stratum at the bottom of the shaft is at the bottom of the soil layer on the side of the shaft.

[0012] The shaft wall is on the side of the soil layer on the side of the shaft.

[0013] The bottom of the steel formwork is on the rock stratum at the bottom of the shaft.

[0014] The triangular support assembly includes a horizontal wooden square installed on the rock stratum at the bottom of the shaft;

[0015] A vertical wooden square in close contact with the steel formwork;

[0016] An inclined wooden square obliquely supporting the top of the vertical wooden square;

[0017] Insert steel bars fixed in the rock formation at the bottom of the hoistway shaft;

[0018] Install a resisting wooden block on the rock formation at the bottom of the hoistway shaft to resist the steel bars. A notch is formed between the resisting wooden block and the horizontal wooden beam for the bottom of the inclined wooden beam to be inserted. A wooden wedge block is installed at the bottom of the notch to adjust the height of the bottom of the inclined wooden beam.

[0019] A triangular notch is formed between the wooden wedge block and the horizontal wooden beam to engage with the bottom triangle of the inclined wooden beam.

[0020] The beneficial effect of the present utility model is that: the bottom of the inclined wooden beam is inserted into the notch formed between the resisting wooden block and the horizontal wooden beam, and a corresponding wooden wedge block is installed in the notch to adjust the height of the bottom of the inclined wooden beam, realizing the stable support of the adjustable hypotenuse of the triangular support assembly for the steel formwork, and solving the problem that the inclined support rod, the adjustable support rod, and the fixed support rod are not convenient to adjust by welding or using bolt connection to adapt to the support of the formwork.

Detailed Embodiment

[0023] The technical solution of the present utility model will be further described below, but the scope of protection is not limited thereto.

[0024] As Figure 1 shown.

[0025] A construction structure for supporting the formwork of the hoistway shaft wall of the present application includes:

[0026] The soil layer 11 on the side of the hoistway shaft and the rock formation 12 at the bottom of the soil layer 11 on the side of the hoistway shaft.

[0027] There is a hoistway shaft wall 1 solidified and formed after concrete pouring on the side of the soil layer 11 on the side of the hoistway shaft. There is a steel formwork 2 on the side of the hoistway shaft wall 1, and the bottom of the steel formwork 2 is on the rock formation 12 at the bottom of the hoistway shaft.
