A pouring device for pile foundation construction

Abstract

The invention discloses a pouring device for pile foundation construction, which includes a water blocking pipe, a plurality of shrapnels connected to the outside of the water blocking pipe body, the shrapnels are connected to a movable baffle, the movable baffle is connected to a movable block, the movable There are a plurality of baffles between the blocks, several immersion pipes are installed below the water blocking pipe, and several transmission pipes are installed above the water blocking pipe, and air pipes are clamped in the side connections of the water blocking pipe, immersion pipe and transmission pipe. An air bag is installed at the lower end of the trachea, a barometer is installed at the upper end of the trachea, a vibrating rod is installed inside the transmission pipe, conveying rods are installed on both sides of the conveying pipe body, and a steel cage is arranged on the conveying rod of the vibrating rod to convey The arm also includes a quick connection device for the steel cage; the invention can connect and place the steel cage at the same time as pouring, does not need to consume water blocking plugs, can automatically adjust the concrete rising speed, does not need to measure the immersion depth of the conduit, and the concrete is not easy inside the conduit accumulation.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a pouring device for pile foundation construction. Background technique [0002] The foundation composed of piles set in the rock and soil and the cap connected to the top of the pile or the single pile foundation directly connected by columns and piles is called pile foundation. The construction process of organizing and implementing this pile foundation is called pile foundation engineering. In pile foundation construction, pile holes will be formed in the foundation soil by means of mechanical drilling, steel pipe extrusion or manual excavation, and then the prefabricated steel cage will be vertically hung into the hole, fixed after positioning, and finally used Concrete is poured into the conduit to make piles. [0003] However, in the existing pile foundation construction, it is necessary to weld the reinforcement cage and put it into the pile hole first, an...

Problems solved by technology

[0003] However, in the existing pile foundation construction, it is necessary to weld the reinforcement cage and put it into the pile hole first, and then pour the concrete, which is very time-consuming and greatly prolongs the construction period; at the same time, it is necessary to place a water blocking plug in the conduit when the pouring is started. It is used to accumulate concrete in the conduit in advance, and the water blocking plug cannot be recovered after pouring; and due to the difference in the diameter of the pile hole during pouring, the rising speed of the concrete is also different. It is necessary to always pay attention to the rising speed of the concrete and measure the immersion depth of the conduit frequently. Accidents are very troublesome; in addition, when concrete is poured, the concrete inside the conduit is easy to accumulate, causing the conduit to block
