Large-tonnage pile foundation test loading device

Abstract

The invention relates to the field of pile foundation load tests and particularly relates to a pile foundation test loading device which is relatively great in quantity of involved single engineering piles and relatively great in load. The invention discloses a large-tonnage pile foundation test loading device. The large-tonnage pile foundation test loading device comprises a cone-shaped beam, anchor pile sets and loading systems. The cone-shaped beam comprises a column, diagonal draw bars, cross arms and connecting systems; the anchor pile sets are arranged below the joints of the diagonal draw bars and the cross arms of the cone-shaped beam, and the loading system is arranged between the bottom of the column of the cone-shaped beam and the top of a test pile. By adopting a structural body where the cone-shaped beam is matched with the anchor pile sets, large-tonnage test load application can be realized. The assemblies of the device are detachably connected and the device can be adaptive to the condition that the quantity of the single engineering piles is relatively great and the load is relatively great, so that the construction efficiency is effectively improved and the construction cost is effectively lowered; an anchoring loading device is continuously used.

Description

technical field [0001] The invention relates to the field of pile foundation load tests, in particular to a pile foundation test device with a large number of single engineering test piles and a relatively large load. Background technique [0002] With the continuous development of the world economy, infrastructure construction has entered a stage of rapid growth, and this trend is more obvious in developing countries. As one of the most widely used and common foundation forms, pile foundation is developing towards larger diameter, longer length and more individual items. At this time, higher requirements must be put forward for the pile foundation engineering test. [0003] The conventional pile foundation test method usually adopts the heap load method, the anchor pile method or a combination of the two methods according to the test load and the layout of the test site. These methods all have their scope of application. Among them, the heap load method is suitable for th...

AI Technical Summary

Problems solved by technology

[0004] 1. The beam structure is mainly used, which is bulky, inconvenient to install, and difficult to use backwards

[0005] 2. The traditional pile foundation test load is difficult to achieve large tonnage load loading

[0006] 3. It is difficult to apply to the situation where there are a large number of test piles in a single project

[0007] 4. Large amount of engineering, waste time and waste, high construction cost

However, the static load test loading device used in the traditional conventional pile foundation test is difficult to meet the needs of large-scale, standardization, environmental protection and economy. The current loading reaction device needs to develop towards the trend of light structure, simple disassembly and assembly, and convenient use.
