TECHNICAL FIELD
[0001] The present application belongs to the technical field of concrete pouring formwork construction or device, and particularly relates to a concrete rapid formwork device. BACKGROUND
[0002] Civil construction needs a large number of support operations, such as initial support of tunnel excavation, pit wall support of foundation pit excavation, slope protection of cutting excavation, etc. The commonly used support operation mode is the shotcrete operation mode.
[0003] At present, after the foundation pit excavation is completed, the initial support construction of the foundation pit is generally realized by using the shotcrete with a hanging net, which is mainly divided into two types, one is dry shotcrete, and the other is wet shotcrete. Whether it is wet shotcrete or dry shotcrete, the shotcrete process is as follows: the prepared shotcrete is injected into a shotcrete machine while an external additive for adjusting the setting time is added, high-pressure air of an external air compressor is connected to the shotcrete machine through mechanical action, the shotcrete is sprayed from the pipe of the shotcrete machine according to the set parameters, and a hand or a mechanical hand holds a spraying head to spray on the support surface. The advantages of the shotcrete operation are that it is suitable for irregular terrain, the construction speed is fast, the early support strength is high, the excavation surface can be quickly closed, and the operation is simple. However, the disadvantages are also quite prominent, mainly including the following aspects: the energy consumption is large due to the use of high-pressure air for spraying, a large amount of dust is generated during the shotcrete, which seriously pollutes the environment and harms the health of construction personnel, a large amount of material is wasted due to the rebound of the shotcrete, the construction surface flatness is low, the cost of consumables is high during the construction process, and the pipe is prone to be blocked.
[0004] However, the formwork concrete construction is widely used in the field of civil construction, and is generally used for the main structure construction of building structures, and generally uses general formworks and supports for operation. The operation process mainly includes the following processes: formwork erection, reinforcement, concrete injection, concrete vibration, formwork removal, and curing. Due to the process defects of the formwork concrete, the formwork erection and reinforcement time is long, generally 12 hours, and after pouring, the concrete needs to be waited for strength and curing, generally more than 3 days, which cannot meet the process requirements of the short-time support operation of the foundation pit excavation and the tunnel excavation, and therefore the formwork concrete is less used in the support operation construction. The concrete pouring into the mold mainly includes the following types: direct pouring into the mold, string barrel pouring into the mold, guide pipe pouring into the mold, and concrete pump truck or distributing machine pouring into the mold. The main function of these pouring into mold modes is to transport the prepared concrete to the pouring operation surface. In order to improve the efficiency of the concrete pouring into the mold, the existing concrete pouring into mold devices and distributing machines mainly use pump pipes, chutes, movable elbows, hydraulic devices, etc. to facilitate the concrete transportation process, reduce repeated pipe connection, and facilitate the adjustment of the injection position.
