Description

Construction equipment for concrete piles

technical field

The utility model relates to the technical field of civil engineering equipment, in particular to a construction equipment for concrete piles.

Background technique

In the foundation treatment of buildings, it is often encountered that there are dense sandy soil layers, gravel soil layers, loess layers, gravel and pebble layers, etc. at a certain depth below the surface, and the hardness of these soil layers is uneven. , Uneven thickness. This geological condition makes it very difficult to form holes in the pile body during pile foundation construction. At present, it is difficult to form pile holes to the design depth with the commonly used methods such as vibratory sinking, static pressure or rotary drilling, which makes construction difficult. Increase and extend the construction period. Although rotary drilling rigs and manual digging can form holes in relatively hard soil layers, they are both methods of taking out the original soil. Not only does it need to clear the soil and transport it outside, resulting in increased costs and environmental pollution, but also because the original soil and soil are not fully utilized. Without the retaining wall, it is very easy to cause the hole wall to collapse and shrink, especially when the groundwater content is high, the pile hole will be flooded with water quickly, and the next step of construction cannot be carried out.

In the invention patent with the application number 201410616111.5, a construction equipment for concrete piles is disclosed, including a casing, a weight, a hoist, a chassis, and a bracket. The characteristics are: a high-power hoist and a small-power hoist are fixed on the chassis, The front end of the chassis is provided with a bracket perpendicular to the chassis, and the upper end of the bracket is equipped with a pulley; the rated load of the high-power hoist is 40kN ~ 80kN, and the wire rope protruding from the high-power hoist passes around the pulley at the upper end of the bracket, and then passes around The pulley is set on the top of the heavy hammer, so that the high-power hoist can drive the heavy hammer to lift; the heavy hammer is a slender steel heavy hammer that can penetrate into the casing, and the bottom of the heavy hammer is pointed or flat, with a weight of 5 to 10 tons ;The rated load of the small-power winch is 20kN～60kN. The steel wire rope protruding from the small-power winch passes through the pulley and the reverse device at the upper end of the bracket to connect with the casing, so that the small-power winch drives the casing to lift; the casing is A certain length of steel pipe with openings at both ends, the diameter of the casing is larger than the diameter of the above weight, the upper end of the casing is provided with a verticality control device, and the upper end of the casing is provided with a filling port; the upper end of the casing can also be equipped with a vibration device.

This patent has the following defects in use: because the diameter of the weight is smaller than the casing, the casing is easy to get stuck when sinking into the pile hole. In this patent, the casing is pressed down by vibration or back pressure, and the shallow depth This method can also be effectively realized, but when it reaches a certain depth, the density of the soil below is greatly increased, and it is difficult to move the casing downwards only by providing vibration and back pressure, and it is impossible to protect the poured concrete, which may cause concrete damage. The construction of the pile failed. And the low-power winch that connects on the casing only provides downward counter pressure, does not provide the upward force of casing, will have very big trouble when taking out casing.

The technical solution is that the utility model includes a base, which is characterized in that a bracket is provided on the base, a first pulley is installed on the upper end of the bracket, a first hoist is fixed on the base, and the steel wire rope of the first hoist is connected by the first pulley. There is a heavy hammer, which constitutes the structure that the first winch controls the rising of the heavy hammer. The outer side of the heavy hammer is covered with a protective tube. There are slide rails around the cylinder, and a chute matching the slide rail is fixed on the base to form a structure that the casing slides in the chute and can only move up and down. The lower end of the casing is provided with a rotatable stopper. A cylinder is installed inside, the front end of the cylinder is provided with a circular ring, and the circular ring is fixed on the block to form a structure for the cylinder to control the rotation of the block.

The utility model has the advantages of reasonable structure, low manufacturing cost, convenient transportation and use, can form concrete piles in a very fast time, speeds up the construction progress, shortens the construction period, and greatly improves the efficiency.
