Abstract

The portable mechanically assembled ground fixation stake device is applied to the engineering of treating land earthwork, water-based desilting, excavating materials, moving, land, underwater heavy objects, civil engineering, harbor, river, lake construction and the like, and is characterized in that the whole device is fixed only by the action of the working tensile force itself. The whole device has six stake columns 2a, 2b, 4a,4b, 9, 1) arranged on the ground, wherein four constituent brackets (2a, 2b, 4a, 4b) are supported on the ground. The top ends of the four supports are mounted on the shaft (6), and a cuboid rigid block (15) is mounted in the middle of the shaft (6). When the system is subjected to pulling force, the cuboid rigid block (15) rotates around the central shaft (6), and due to the opposite movement direction of the two end points of the cuboid rigid block (6), the tension conversion direction of the system forms an inclined downward pressure, so that the protective stake (9) is subjected to pressure at the same time from the pressure rod (7), and due to the fact that the tensile force and the pressure are synchronized, the greater the tension force is also increased, so that the whole device achieves the effect of fixing the stake. The device is light in weight and convenient to carry, and can be mounted and disassembled anywhere.

BEST MODE FOR CARRYING OUT THE INVENTION

[0039] The invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0040] The invention relates to a portable mechanically assembled ground fixation stake device, which is applied to fixed stakes of temporary cables, steel cables and steel ropes when being applied to engineering such as land earthwork, water system desilting, excavating materials, moving, land, underwater heavy objects, civil engineering, harbor, river, lake construction and the like. The device is not suitable for being used as a permanent soil stake, a bridge stake, a bridge pier, a suspension cable stake and the like.

[0041] The method has the advantages that the size is different, the specification model is different, when the product is used, the appropriate specification model is selected according to the weight of the material during construction, and when the selection is selected, according to the “building stake foundation technical specification” (JGJ94-2008).

[0042] According to the preparation process of the specification model of the product, firstly, the whole device is considered to be a rigid body, the pushing force of the whole device during working on the soil pressure is established, and a mathematical model of the critical value accumulated by the surrounding soil is determined. The establishment method of the mathematical model of the soil pressure adopts the Rankine soil pressure theory and the Coulomb soil pressure theory

[0043] In 5.7 sections of the “building stake foundation technology specification ‘(JGJ94-2008), a single stake horizontal bearing capacity characteristic value is given.

[0044] The large building single-stake foundation and the foundation stake in the group stake with small horizontal load and small horizontal loads should meet the following formula

Hik≤Rh(5.7.1),   Requirements:

Hik-the horizontal force acting on the top of the foundation stake I stake under the combination of the load effect standard;

[0045] The horizontal bearing capacity characteristic value of the base stake in the Rh-single stake foundation or the group stake is the horizontal bearing of the single stake foundation for the single stake foundation Force characteristic value RHA.

[0046] However, in the invention, the portable mechanically assembled ground fixation stake device not only is suitable for horizontal bearing capacity, but also is suitable for the inclined upward bearing capacity within a certain angle (shown in FIGS. 1, 2, 4, 5 and 6).

[0047] In combination with FIG. 1, when the bearing capacity is a non-horizontal inclined upward direction, the horizontal dividing force of the bearing capacity is met, that is:

HIK*cos α≤RH,

In the formula, α=41° (shown in FIG. 1)

[0048] The determination and calculation formula of the horizontal bearing capacity characteristic value of the RH single stake should be 5.7.2 in the “Building Stake Base Technical Specification” (JGJ94-2008). The specification of the section does not need to be listed here.

[0049] In the invention, it is to be noted that the portable mechanically assembled ground fixation stake device carries the stake of the working load and is not a stake. It can be seen clearly in connection with FIG. 4 that the common four stakes together bear the working load. Due to the fact that the angle, the length and the length of the four stakes are different, the soil characteristics of the installation site and the like are different, and therefore the method is not suitable for considering the group stake effect.

[0050] Through practical application, the total horizontal load is divided into four obtained values to be calculated as the horizontal load of one stake column, the required length and width of a stake column are obtained, the most suitable specification model is selected from the series products of the invention to be assembled and then used.

[0051] Preferably, the lifting ring (12) can move up and down along with the change of the direction angle of the load acting force, the smaller the included angle between the acting force direction and the ground, the lower the lifting ring (12) can move downwards, ie, the closer to the ground.

[0052] Preferably, the connecting cable (13a-b) can select a single strip or two strips according to the positions of different soil and lifting rings (10a-b). In general, when the lifting ring is at the ground, the lifting ring (10a-b) selects two lifting rings, and when the lifting ring is underground, The cable (10a-b) selects single strip.

[0053] Preferably, the four leg brackets (2a-b) and (4a-b) may select three leg brackets (shown in FIG. 5) as desired.

The working steel cables (14a) and (14b) generate a pulling force. As the direction of the working steel cables (14a) and (14b) is inclined upwards, an included angle of 30 degrees is formed on the same ground; therefore, as the working steel cables (14a) and (14b) generate tension. According to the invention, the protection function of the device (16a) and (16b) is woken up, and the reverse pulling force formed by the device (16a) and (16b) acts on the working steel cable (14a) and (14b) as described in the conversion route of the force recorded in the above content. Similarly, the carrying system is suspended by the large-span stereo overhead cableway, and the pulling force applied to the device (17) of the device (17) is also awakened by the steel cables (20) and (21) on the other side to also wake up the automatic protection function of the device (17). At this time, the whole system of assembling and linking the large-span three-dimensional overhead cableway suspension mining and carrying system by three sets of the devices (16a), (16b) and (17) can complete the engineering construction work under the condition of balance safety.
