Description

High-pressure pouring type spiral foundation pile module

The new model relates to a kind of construction equipment, especially a high-pressure pouring type screw foundation pile module.

When constructing large buildings or high-rise buildings, if the stratum strength is insufficient, soft soil layer or liquefied soil, engineering companies often use foundation piles driven into the ground to transfer the load of the superstructure through the foundation piles to the soil bearing layer to improve The safety and stability of the building structure.

In recent years, the common construction method of foundation piles is to first drill a hole with sufficient depth in the ground, then pour cement slurry into the hole, and put the foundation pile pipe body into the hole by percussion or implantation to make the cement The slurry is filled inside the pipe from the bottom of the pile pipe. As part of the cement will overflow between the foundation pile pipe body and the hole, it will be mixed with the surrounding soil, and then flow back to the top edge of the pipe body, so that the pile head at the top of the foundation pile will solidify into inferior concrete mixed with soil. Then, the surrounding soil of the pile head is excavated to expose the pile head, and the inferior concrete is removed, and then a steel cage is inserted into the pipe body to form an implanted foundation pile.

In addition, for general shallow foundation piles, the construction methods are: 1. Lofting; 2. Excavation; 3. Fixing the screw base; 4. Fixing with cement. The above steps need to be completed in order to complete the foundation piles connecting the building and the ground, so the installation of the foundation piles takes many days to complete.

It can be seen that the existing foundation piles and their construction methods have the following shortcomings that need to be improved:

1. Time-consuming and costly: Whether it is an implanted foundation pile or a shallow foundation stub, it is necessary to excavate a hole of appropriate depth before placing the foundation stub and pouring the cement, resulting in time and cost of construction. Higher labor costs.

2. Backfilling soil causes waste of resources: When the concrete around the pile head is solidified, the soil around the implanted pile head is excavated, so that the pile head protrudes to the outside and the inferior concrete is removed. During the construction process, the soil must still be backfilled. The compaction makes it stable, the cost is higher and it is not in line with the concept of environmental protection.

In view of this, the purpose of the present invention is to provide a high-pressure perfusion type spiral foundation pile module that can be constructed without drilling and digging. .

The novel high-pressure pouring type spiral foundation pile module includes a plurality of spiral ground piles, a rotating mechanism, and a pouring mechanism. Each spiral pile includes a hollow pile body that surrounds an accommodating space, a plurality of drill cutting edges arranged at intervals along the outer surface of the pile body, and a plurality of drill cutting edges that penetrate the pile body and are respectively arranged in the Drill the perforations between the cutting blades, and the perforations communicate with the accommodating space. The rotating mechanism is detachably combined with the top end of the spiral ground pile to screw the spiral ground pile downward into a set position. The pouring mechanism is used for pouring the soil modifier from the top of each spiral pile into the corresponding accommodating space and seeping out from the perforation.

Another technical method of the present invention is that each spiral pile further includes a connecting seat connected to the top of the pile body and extending outward along the radial direction of the pile body.

Another technical means of the present invention is that the rotating mechanism includes a base, a power source arranged on the base, a rotating seat driven by the power source and capable of being combined with the connecting seat, and a set The grip on the base.

Another technical means of the present invention is that the pouring mechanism includes a containing tank for containing the soil modifier, and a pouring port connected to the containing tank.

The effect of the new model is that there is no need to drill holes in advance when in use, as long as the spiral pile is directly screwed in at the predetermined installation position, and then the soil modifier is poured to make it overflow from the perforation. The soil around the screw ground pile is solidified, so that the screw ground pile can stand firmly at the predetermined installation position, shorten the construction period and reduce the manufacturing cost, and is especially suitable for the foundation of light buildings.

The characteristics and technical content of the patent application related to the present model will be clearly presented in the following detailed description of the preferred embodiment with reference to the drawings. Before detailed description, it should be noted that similar components are represented by the same numbers.

As shown in FIG. 2( b ), the pouring mechanism 4 includes an accommodating groove 41 for accommodating the soil modifier, and a pouring port 42 connected to the accommodating groove 41.

Before use, the operator first explores the geological conditions of the predetermined location, such as the structure of the soil (not applicable if it is a rock slab), water content, compactness and other conditions, while considering the bearing requirements of the building to determine the spiral pile 2 specifications, and the depth of the screw pile 2 into the predetermined setting position. In addition, the new model is more suitable for light building foundations, such as tin house foundations, landscape platforms, footpath foundations, street lights, road sign foundations, etc. Because of the wide range of applications, multiple specifications can be distinguished according to their diameters to meet the use of various industries . Among them, the spiral pile 2 can be preliminarily divided into specifications with a diameter of less than ten centimeters and specifications with a diameter of more than ten centimeters. Those with a diameter less than ten centimeters can be formed by pressing steel pipes, and those with a diameter greater than ten centimeters can be made by casting. . Of course, the above specifications and manufacturing methods are only examples of this embodiment and are not limited thereto.

Next, according to the results of the survey, the screw ground piles 2 of appropriate specifications are selected, and the depth of screwing into the screw ground piles 2 and the distribution position and density of the screw ground piles 2 are determined. As shown in FIG. 3, the rotating mechanism 3 is arranged at the top end of the spiral pile 2, that is, after the rotating seat 33 of the rotating mechanism 3 is respectively combined with the connecting seat 24 of the spiral pile 2, The operator holds the grip portion 34 of the rotating mechanism 3, and activates the power source 32 to drive the rotating base 33 to start rotating, and synchronously drives the spiral pile 2 to rotate. Since each spiral pile 2 has the drilling and cutting edge 22, while being driven by the rotating seat 33 to rotate, the drilling and cutting edge 22 will cut the soil at the predetermined position, and can rotate at the same time Continue to move down and continue to move down to a predetermined depth.

After all the spiral piles 2 are set up, the pouring of the soil modifier is started. Among them, the choice of soil modifier is also determined based on the results of exploration, and the most common user is concrete. Referring to FIG. 4, the soil modifier is accommodated in the accommodating groove 41 of the pouring mechanism 4, and the soil modifier is poured through the pouring port 42. After fixing the pouring port 42 of the pouring mechanism 4 to the connecting seat 24 of each spiral pile 2, the soil modifier can be poured into the hollow pile body 21 of the spiral pile 2 at high pressure, and The soil modifier is allowed to seep out to the periphery of the pile body 21 through the perforation 23 on the pile body 21 to solidify the soil around the spiral ground pile 2 and combine the spiral ground pile 2 with the soil to strengthen the spiral ground The friction between the pile 2 and the soil can also increase the bearing capacity of the screw ground pile 2 on the building. In addition, it should be noted that when the spiral pile 2 is to be combined with the rotating mechanism 3 or the pouring mechanism 4, a washer 25 can be provided on the connecting seat 24 to increase friction and prevent soil modifiers. Leakage during infusion.

Take the mountain climbing trail in Chaishan National Natural Park as an example. According to its construction specifications, the column connecting the trail to the ground is located on a foundation pier that is 30 cm long, 30 cm wide, and 40 cm high. A foundation pier weighs about 80 cm. Kilograms, the completion of a hiking trail requires at least hundreds of foundation piers. The construction materials (cement, gravel, sand) can range from dozens of tons to hundreds of tons. It takes a lot of money to carry the above-mentioned materials up the mountain. Manpower, if the new design can be used, not only can effectively reduce the excavation of mountains and forests, but also can reduce the manpower and time required to carry materials.

From the above description, it can be known that the new high-pressure perfusion type spiral foundation pile module does have the following advantages:

1. No need to excavate in advance: Compared with the previous technology, the existing foundation pile structure needs to excavate a hole of appropriate depth at a predetermined location first. The spiral pile 2 of the present invention does not require advance For excavation, through the design of the drilling and cutting blade 22, the rotation mechanism 3 can be driven to rotate and directly screw down into the ground.

2. Significantly shorten the construction period: because the new model does not require excavation, as long as the spiral pile 2 is directly screwed into the ground using the rotating mechanism 3, the excavation time can be saved, and the construction period can be greatly shortened .

3. Reduce environmental damage: Large-scale machinery and tools are needed in the excavation process. If the construction site is in a mountain forest, it may cause environmental damage in areas outside the construction site when large-scale machinery and tools are stationed. The new model does not require large-scale machinery and tools to be stationed in the construction area, and can effectively reduce the damage to the surrounding environment of the construction area.

To sum up, the new type of high-pressure perfusion screw foundation pile module does not need to be drilled and digged in advance, as long as the screw foundation pile 2 is directly screwed in at the predetermined installation position, and then the soil is modified. The filling of the agent to make it overflow from the perforation 23 can solidify the soil around the spiral pile 2 so that the spiral pile 2 can stand firmly at the predetermined installation position, shorten the construction period and reduce the manufacturing cost.
