Embodiment

[0021] Example: such as Figure 1-7 As shown, a method for pouring concrete conduits of bored piles according to the present invention. First, a leak test is performed on a conduit 1 composed of a plurality of steel pipes; after the test is completed, a storage hopper 4 is installed at one end of the conduit 1; Place it in the pile hole 6; after placing the conduit 1, install the sealing plate 5 on the bottom of the storage hopper 4; pour concrete into the storage hopper 4 after the sealing plate 5 is installed; then pull out the sealing plate 5 , into the concrete and the pile hole 6; repeat the above steps of pouring into the concrete. Repeat intervals are less than 30 minutes.

[0022] The conduit 1 is composed of several steel pipes, and a sealing ring 3 is arranged between the steel pipes and fixed by a flange 2 . Fixed steel plates 7 are arranged on both sides of the hole of the pile hole 6 . The distance between the bottom of the conduit 1 and the poured concrete top...

Abstract

The invention provides a bored pile tremie pouring method. The method comprises the steps that firstly, a leakproofness test is carried out on a guide pipe composed of a plurality of steel pipes; secondly, after the test is completed, a storage hopper is mounted at one end of the guide pipe; thirdly, the guide pipe is placed in a pile hole; fourthly, after the guide pipe is placed well, a sealing plate is mounted at the bottom of the storage hopper; fifthly, after the sealing plate is mounted, concrete is filled into the storage hopper; sixthly, the sealing plate is pulled out, and the concrete is filled into the pile hole; seventhly, the concrete filling step is repeated. The guide pipe is composed of the steel pipes; sealing rings are arranged between the steel pipes and fixed through flanges. The two sides of an orifice of the pile hole are provided with fixed steel plates. Through the method, pouring of the pile hole can be efficiently and quickly completed, and the pouring effect cannot be affected. Operation is simple, and the use cost is low.

Description

technical field [0001] The invention relates to a pouring method, in particular to a concrete conduit pouring method for bored piles. Background technique [0002] In the actual construction, the specific method is to use the closed connecting steel pipe (assembled into a conduit) as the conveying channel of the bored pile concrete, and the construction method assisted by the storage hopper and the funnel for concrete pouring. Due to the deep hole depth of bored piles, it is difficult to pour concrete, and segregation is prone to occur. The formed pile body is prone to common quality problems such as broken piles and insufficient strength of single piles. Affect the overall safety and stability of the foundation and foundation, and bring trouble to the construction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for pouring concrete pipes for bored piles, using a closed connecting steel pipe as the...
