Problems solved by technology

For deep foundation pits, the erection height of the bent frame is very large, and the impact force of the concrete on the wall of the slide pipe is also great, so not only the workload of erecting the bent frame is large, but also the risk of erecting and concrete pouring is very high
Moreover, after the chute is erected, it cannot be moved, and only a fixed small area can be poured.
Therefore, the traditional slide pipe construction method needs to build bent frames, which makes the pouring workload very large in the early stage, and there are certain risks during construction, and the pouring position is not flexible, and only a small fixed area can be poured
[0004] Even with the combination of the above two methods, the effect is still not satisfactory

Embodiment 1

[0041] Such as Figure 1 to Figure 3 As shown, the tool chute 100 provided in this embodiment is used for pouring concrete, and is installed at the enclosure structure of the foundation pit, using the supports and trestles in the enclosure structure of the foundation pit as the supporting points of the tool chute 100 . That is to say, the present embodiment utilizes supports and trestles as supports for the chute 10, which saves labor and material costs for erecting and dismantling the bent racks, and greatly shortens the construction time of the chute 10, speeds up the construction, and avoids the danger of setting up high bent racks To ensure the safety of construction. Wherein, trestle board 1 place is provided with trestle hole, is used for hoisting chute 10. The utility chute 100 may generally include: a chute 10 , a lower hopper 20 , a movable lower hopper 30 and a small chute 40 . The slide pipe 10 is welded by two iron pipes of equal diameter and equal length, and th...

Embodiment 2

[0049] see Figure 1-Figure 3 , the present invention also provides a construction method using the tool slide pipe 100, which is used for the construction of large-volume concrete pouring in deep foundation pits, and the construction is carried out according to the following steps:

[0050] Step 1, making and processing the chute 10 of the tool type chute 100;

[0051] Step 2, making tool type chute 100 lower hopper 20 and movable lower hopper 30;

[0052] Step 3, using the support and the trestle as the support for the chute 10, installing and fixing the chute 10;

[0053] Step 4, install and debug the lower hopper 20 and the movable lower hopper 30;

[0054] Step 5, the concrete flows into the chute 10 through the lower hopper 20, and the pouring direction is adjusted through the movable lower hopper 30 and the small chute 40 to complete the pouring of the concrete.

[0055] The construction method of the invention is simple and convenient, the construction speed is acce...

Abstract

The invention discloses a tool type chute and a construction method, and belongs to the field of building construction. The tool type chute is mounted on a foundation pit enclosure structure; a support and a trestle in the foundation pit enclosure structure are used as support points of the tool type chute; and a trestle plate is provided with a trestle hole for lifting the chute. The tool type chute comprises the chute, an unloading hopper, a movable unloading hopper and a small chute. The chute is fixed in the corresponding support place through channel steel and a hoop, and is provided withan inclined angle. The chute is formed by welding two iron pipes; and an included angle is formed between the two iron pipes. The unloading hopper is arranged in the trestle hole. The movable unloading hopper is arranged in a chute lower port. The small chute is arranged in the chute lower port, and is freely rotated along with the movable unloading hopper. The tool type chute saves the labor andmaterial consumption needed by rack building, accelerates the construction speed, guarantees the safety in the construction process, widens the casting range, improves the flexibility, reduces the noise pollution, and meets green construction requirements.

Description

technical field [0001] The invention relates to a tool-type chute and a construction method, belonging to the field of building construction. Background technique [0002] With the development of the city, the number of high-rise and super high-rise buildings is increasing day by day, and the concrete volume of the foundation floor is also increasing. However, there are fewer and fewer roads that can be used for arranging construction. When pouring large-volume concrete, in order to avoid construction joints between old and new concrete, the time interval between pouring and tamping should not be too long, which makes site layout and pouring efficiency particularly important. [0003] There are two traditional construction methods: one is to use a car pump for pouring. Because the car pump is convenient for construction and flexible for pouring, it is one of the most commonly used pouring methods for concrete pouring today. However, sufficient parking space is required for ...
