Description

Technical Field

[0001] This utility model belongs to the field of cast-in-place pile construction technology, and specifically relates to an environmentally friendly pile driving construction equipment. Background Technology

[0002] Currently, during the driving process of precast piles, it is necessary to pre-drill holes and mix soil, cement, and water inside the pile holes. Due to the poor environmental performance of existing mixers, cement spillage at the construction site causes serious pollution. Moreover, the soil layers at the drilling site may contain sand and gravel layers. The soil brought out by the drill rod contains sand and gravel, which can easily increase the mixing friction and reduce efficiency when mixed with cement. This not only results in high power consumption but also poor mixing effect. After mixing, the sand and gravel tend to settle, causing the piles to not be driven in place. Aeration is required for separation, which can seriously affect the construction progress and the quality of pile driving. Utility Model Content

[0003] To address the above problems, this utility model provides an environmentally friendly piling construction equipment.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An environmentally friendly piling construction equipment includes a chassis and a crane and a piling machine mounted on the chassis. The piling machine includes a long spiral drilling rig and a pile driving mechanism on its side. The drill rod of the long spiral drilling rig is fitted with a casing. The lower side outlet of the casing is connected to the inlet of a conveyor. The outlet of the conveyor extends to the top feed port of a crusher. The discharge port of the crusher extends to the top feed port of a mixer. The discharge port of the mixer is connected to a conveying assembly. The conveying assembly is used to convey the mixed material to the top of the drill rod and into the inner hole of the drill rod.

[0005] Furthermore, it also includes a storage tank, which is located at the bottom of the mixer, and the discharge port of the mixer corresponds to the top inlet of the storage tank; the conveying assembly is connected to the storage tank.

[0006] Furthermore, the conveying assembly includes a conveying pump and a pumping pipe. The inlet of the conveying pump is provided with a feed pipe, the inlet of the feed pipe extends to the middle and lower part of the storage tank, the outlet of the conveying pump is connected to the lower inlet of the pumping pipe, and the upper outlet of the pumping pipe is connected to the top inlet of the drill rod.

[0007] Furthermore, the conveyor is a screw conveyor, which is inclinedly positioned between the casing and the crusher.

[0008] Furthermore, a screw conveyor is provided between the crusher and the mixer, and the screw conveyor is inclined between the crusher and the mixer.

[0009] Furthermore, the crusher is a hammer crusher, with a feed inlet on the top side of the crushing chamber and a discharge outlet on the bottom side of the crushing chamber.

[0010] Furthermore, the crusher, mixer, and storage tank are all mounted on the chassis. The crusher is positioned diagonally above the protective casing and is located at the bottom of the chassis. The mixer and storage tank are correspondingly positioned at the top and bottom of the chassis. The conveying pump is located at the top of the chassis.

[0011] Furthermore, the bottom of the chassis is provided with a pair of lateral moving steps and a pair of longitudinal moving steps. The lateral moving steps and the longitudinal moving steps are respectively connected to the chassis through lifting hydraulic cylinders. The middle of the lateral moving steps and the longitudinal moving steps are provided with rails, and the bottom casters of the lifting hydraulic cylinders can move along the rails.

[0012] The technological advancements achieved by this invention compared to existing technologies are as follows: This invention involves attaching a casing to the drill rod of a long spiral drilling rig. The soil brought up by the drill rod falls into the casing and is then conveyed to a crusher. The crusher breaks down the sand and gravel in the soil, which is then thoroughly mixed with water and cement in a mixer to form a slurry. This slurry is then conveyed to the top of the drill rod and enters the pile hole through the inner hole of the drill rod. This invention offers advantages in energy saving and environmental protection. Mixing is performed outside the pile hole, ensuring a water-free and mud-free construction site. It fully utilizes the soil brought up by the drill rod, reducing soil transportation procedures and making construction faster and more efficient. Simultaneously, the finely crushed drilled soil is mixed with cement and water to form a slurry that meets design requirements, ensuring no settlement within the pile hole and guaranteeing the quality of pile driving.

Detailed Implementation

[0015] The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown in the figure, an environmentally friendly piling construction device provided by this utility model includes a chassis 1 and a crane 2 and a piling machine 3 mounted on the chassis 1. The piling machine 3 includes a long spiral drill 4 and a pile pressing mechanism 5 on its side. A casing 7, which is wider at the top and narrower at the bottom, is fitted onto the drill rod 6 of the long spiral drill 4. The lower side outlet of the casing 7 is connected to the inlet of a conveyor 8. The outlet of the conveyor 8 extends to the top feed port of a crusher 9, and the outlet of the crusher 9 extends to the top feed port of a mixer 10. The outlet of the mixer 10 is connected to a conveying assembly, which is used to convey the mixed material to the top of the drill rod 6 and into the inner hole of the drill rod. The casing collects the soil brought out by the drill rod, which is then finely crushed by the crusher, mixed with water and cement in the mixer to form a slurry, and then poured into the borehole by the conveying assembly and the drill rod to fix the precast piles that are hoisted and pressed in. This solution can make full use of the soil discharged from the borehole and mix it outside the pile hole, so as to achieve a water-free and mud-free construction site, which is energy-saving and environmentally friendly.

[0017] Further optimization of the above structure includes a storage tank 11, which is located at the bottom of the mixer 10, with the discharge port of the mixer 10 corresponding to the top inlet of the storage tank 11; the conveying assembly is connected to the storage tank 11. The storage tank allows for the storage of a large quantity of the mixed slurry, ensuring continuous subsequent pouring and preventing downtime due to lack of slurry.

[0018] In specific embodiments of this utility model, such as Figure 1 As shown, the conveying assembly includes a conveying pump 12 and a pumping pipe 13. The inlet of the conveying pump 12 is provided with a feed pipe 14, the inlet of which extends to the lower middle part of the storage tank 11. The outlet of the conveying pump 12 is connected to the lower inlet of the pumping pipe 13, and the upper outlet of the pumping pipe 13 is connected to the top inlet of the drill pipe 6. Using a conveying pump and pumping pipe to convey slurry into the drill pipe is existing technology and will not be described in detail here.

[0019] In specific manufacturing, the conveyor 8 is a screw conveyor, which is inclinedly positioned between the casing 7 and the crusher 9. The feed inlet of the conveyor is connected to the outlet of the casing, enabling the soil discharged from the casing to be continuously transported into the crusher.

[0020] To further optimize the above structure, a screw conveyor 15 is provided between the crusher 9 and the mixer 10, and the screw conveyor 15 is inclined between the crusher 9 and the mixer 10. The crusher 9 is a hammer crusher, with a feed inlet on the top side of the crushing chamber 16 and a discharge outlet on the bottom side of the crushing chamber 16. The hammers 17 of the hammer crusher can crush the sand and gravel in the soil, ensuring that the particle size meets the requirements of the slurry. Meanwhile, the mixer is equipped with a water inlet and a cement addition inlet at the top, and a vertically arranged mixing shaft with mixing blades inside, enabling thorough mixing of materials. Both the crusher and the mixer can be purchased according to the appropriate specifications based on construction needs.

[0021] In specific embodiments of this utility model, such as Figure 1 As shown, the crusher 9, mixer 10, and storage tank 11 are all mounted on the chassis 1. The crusher 9 is positioned diagonally above the protective casing 7 and is located at the bottom of the chassis 1. The mixer 9 and storage tank 11 are correspondingly positioned at the top and bottom of the chassis 1, respectively. The conveying pump 12 is located at the top of the chassis 1. This arrangement saves space and utilizes two screw conveyors to connect the front and rear equipment, enabling the orderly flow of materials.

[0022] In the specific design, the bottom of the chassis 1 is equipped with a pair of lateral moving steps 18 and a pair of longitudinal moving steps 19, enabling the chassis 1 to move laterally or longitudinally. The lateral moving steps 18 and longitudinal moving steps 19 are respectively connected to the chassis 1 via lifting hydraulic cylinders 20. A track is provided in the middle of each of the lateral moving steps 18 and longitudinal moving steps 19, and the bottom casters of the lifting hydraulic cylinders 20 can move along the track. This structure is described in detail in an integrated piling machine disclosed in Chinese patent CN221721624U, and will not be repeated here.

[0023] The construction process of this utility model is as follows: Step 1: Use the lateral and longitudinal movement steps to move the chassis to the drilling pile position, and use the long spiral drilling rig to drill to the set depth.

[0024] Step 2: When the drill rod is lifted, the soil on the long spiral fan blades falls into the casing, and is then transported to the crushing chamber by a screw conveyor. Several hammers are used to finely crush the sand and gravel in the soil, and then it is transported to the mixer by another screw conveyor. Water and cement are added to the mixer according to the cement-soil pile ratio (this is the existing technology), and the slurry formed by mixing is stored in the storage tank for later use.

[0025] Step 3: During the drill rod lifting process, the material is transported to the top of the drill rod using a delivery pump and pumping pipe, and then poured into the pile hole through the drill rod until the design elevation is reached. At this point, pile A is completed, and the machine is moved to the next pile, pile B.

[0026] Then, a crane is used to lift the precast pile to the drilling position and lower it. The precast pile sinks into place under the action of gravity, and there is no settlement in the pile hole.

[0027] In summary, this utility model can be completed in one go on the chassis of a long spiral drilling rig, reducing the handling process, making construction convenient and quick, and doubling the construction efficiency.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
