Embodiment Construction
[0035] The following is attached Figure 1-5 The application is described in further detail.
[0036] The embodiment of the present application discloses a large-diameter pouring pile underwater concrete pouring operation control platform. refer to figure 1 and figure 2 , the large-diameter pouring pile underwater concrete pouring operation control platform includes a skeleton 1 and a clamping plate 2 installed on the skeleton 1. The skeleton 1 consists of two I-beams 4. After mechanical calculations, the I-beam 4 adopts 20a type and is used in a specific When the situation cannot meet the load-bearing requirements, no less than 22a-type I-beam 4 can be used; the clamping plate 2 is composed of two double-opening steel plates 3, one side of the steel plate 3 is provided with a semicircular hole 5, and the semicircular holes 5 of the two steel plates 3 The cross-section is set as a semicircle, and two semicircular holes 5 are surrounded by an injection port 6 for placing th...

The invention relates to a large-diameter cast-in-place pile underwater concrete pouring operation control platform, and relates to the field of cast-in-place pile construction, the large-diameter cast-in-place pile underwater concrete pouring operation control platform comprises a framework and a clamping plate installed on the framework, the framework is composed of two pieces of I-shaped steel, the clamping plate is composed of two steel plates capable of being opened bilaterally, and the steel plates are provided with semicircular holes; the semicircular holes of the two steel plates define a material injection opening used for containing a hopper, fixing assemblies are fixedly connected between the two steel plates and the two I-beams, and the two I-beams are fixedly connected. The device has the effect that the two steel plates are convenient to install, it is guaranteed that the hopper is placed in the injection port, the position between the framework and the pile casing is positioned, and it is guaranteed that commercial concrete is poured into the cast-in-place pile normally.
Description
technical field [0001] The present application relates to the field of cast-in-place pile construction, in particular to a large-diameter cast-in-place pile underwater concrete pouring operation control platform. Background technique [0002] At present, underwater concrete pouring construction is a method of pouring concrete through vertical pipes and relying on the self-weight of concrete; it is suitable for underwater or underground projects such as pouring cofferdams, caisson foundations, caisson foundations, underground diaphragm walls, and pile foundations. [0003] In the process of pouring cast-in-place piles under water, conduits and operation control platforms are used. For general small and medium-diameter (≤Ø800mm) and large-diameter (Ø800-Ø1200mm) cast-in-place piles, the operation and control platform is relatively simple. Ø1200mm), the simple operation and control platform mentioned above cannot meet the requirements of underwater concrete pouring. [0004] I...
