Problems solved by technology

The grounding area of ​​the inner ship and the outer ship is the core factor affecting the overall design. For the same weight, the smaller the grounding area, the greater the pressure on the system on the ground. If there is not enough grounding area, the supporting walking ability of the system in different site environments will be affected. Great constraints, the construction site with very soft surface soil may be difficult to move, thus reducing the practicality, which is also a common problem in practical applications
Theoretically, the grounding area can be increased according to the demand, but what it brings is that the hull of the inner ship and the outer ship will be enlarged and strengthened, and the structure of the platform will be enlarged and strengthened accordingly, which will not only increase the manufacturing cost, but also generate transportation capacity, cost, etc. question

Embodiment 1

[0039] Such as figure 1 , 2 As shown, the anchor pile mechanism 7 described in Embodiment 1 includes an anchor pile 702 and an anchor pile clamping accessory, and an anchor pile through hole 701 is set on the outer ship 3, and the anchor pile clamping accessory is fixed on the outer surface above the anchor pile through hole 701. On the ship 3, the anchor pile 702 is vertically installed in the anchor pile through hole 701, the two side walls of the anchor pile 702 are provided with raised stoppers 703 at intervals, the top of the anchor pile 702 is provided with a pile cap 704, and the anchor pile clamping accessories include brackets And the pressure plate 706 that is located on both sides of the anchor pile symmetrically and rotates around the rotating shaft 705 supported by the bracket. The inner side of the pressure plate 706 is close to the anchor pile against the stopper 703, and the upper side of the pressure plate 706 is connected with a return spring 707. Insertion ...

Embodiment 2

[0042] Such as image 3 As shown, the anchor pile through hole 701 is set on the inner ship 3, and the anchor pile clamping accessories are fixed on the inner ship 3 above the anchor pile through hole 701 around the top, and the rest are the same as in embodiment 1.

[0043] Brief description of the working method: After the system reaches the designated detection position, the anchor pile 702 is pressed in and pulled out through the expansion and contraction of the outer ship lifting cylinder 405. Taking the pressing in as an example, as shown in image 3 , Figure 4 As shown, insert the limit plug 708 into the lower part of the pressure plate 706 (the limit plug needs to be inserted into the upper part of the pressure plate when the anchor pile is pulled out), the outer ship support system, the outer ship lifting cylinder 405 will lift the inner ship hull, and the anchor The pile 702 is affected by its own weight and does not move accordingly. The bottom of the pressure pla...

Embodiment 3

[0045] Such as Figure 4 , Figure 5 As shown, the anchor pile mechanism 7 includes an anchor pile 702, an anchor pile clamping accessory and an anchor pile oil cylinder 710. The anchor pile clamping accessory is connected to the two ends of the pressure-bearing platform 1 through the anchor pile oil cylinder 710, and the anchor pile 702 is installed vertically. Through the anchor pile clamping accessories, the two side walls of the anchor pile 702 are provided with raised stoppers 703 at intervals, and the top of the anchor pile 702 is provided with a pile cap 704. Pressing plate 706, the inner side of the pressing plate 706 is set as a slope surface, the bottom edge is close to the anchor pile against the stopper 703, and the outer side is connected with a return spring (707) in a parallel direction. out.

Abstract

The invention discloses a pile-anchor-combing-type foundation-basis compression-resistance static-load test system. The pile-anchor-combing-type foundation-basis compression-resistance static-load test system comprises an internal-and-external ship walking-type foundation-basis compression-resistance static-load test system, and further comprises anchor pile mechanisms. The anchor pile mechanisms comprise anchor piles, the anchor piles are pressed into the underground to form pulling-resistant friction force, and system testing counterforce is jointly provided through the pulling-resistant friction force, the system-self weight and the pressing pressure of a system pressure-bearing platform. According to the pile-anchor-combing-type foundation-basis compression-resistance static-load test system, the anchor pile mechanisms are additionally arranged, the testing counterforce is provided through pile-anchor combing, the total weight of the system is reduced under a same specification system to achieve the same effect, and the system structure is optimized.

Description

technical field [0001] The invention relates to the field of foundation detection, in particular to a pile-and-anchor combined anti-compressive and static load test system for foundations. Background technique [0002] The anti-static static load test of the foundation (hereinafter referred to as the static load test) is a test method that applies pressure step by step on the top surface of the inspected part and measures its settlement over time to determine the bearing capacity. It is the most recognized test method in foundation testing. Intuitive, reliable, and above all traditional methods. The anti-compression and static load test system of the walking foundation foundation of the inner and outer ships realizes the free walking and accurate positioning of the whole system through the cooperation of the outer ship, the inner ship, the rotating platform and the pressure platform, avoids repeated disassembly and assembly, and reduces the unsafe lifting operation It impro...
