Problems solved by technology

[0002] At present, the test molds used for grouting after the self-balancing static load test of the foundation pile are all molds used in the laboratory in the past. The bottom area is large, takes up space, and the upper end is open, so it is inconvenient to carry, transport and maintain outdoors. Moreover, the water generated during the slurry segregation process accumulates on the upper part of the test piece, resulting in deviations in the size and strength of the test piece from the test requirements, affecting the test results

Embodiment 1

[0035] Embodiment 1: A kind of foundation pile self-balancing static load test after grouting and grouting test mold, such as Figure 1-7 As shown, it is composed of L-shaped plate 1, side plate 2, partition plate 3, connecting bolt 4, filter plate 5, and cover plate 6; L-shaped plate 1 includes an integrally formed vertical surface and bottom surface (of course, it can also be detachable structure), a horizontal groove 7 is set on the bottom surface of the L-shaped plate 1 for placing the side plate 2, that is, the width of the horizontal groove 7 is adapted to the thickness of the side plate 2, and the side plate 2 can be inserted into the horizontal groove 7 , and the side plate 2 is opposite to the vertical surface of the L-shaped plate, and the top is flush with the top of the vertical surface; an L-shaped groove 8 is provided on the L-shaped plate 1, and the L-shaped groove 8 extends along the vertical surface and the bottom surface, Perpendicular to the horizontal groov...

Embodiment 2

[0047] Embodiment 2: In this embodiment, the dividing plate 3, the filter plate 5 and the cover plate 6 are all identical in structure with the embodiment 1, as attached Figure 5-7 As shown, the dimensions may of course be increased or decreased. A kind of foundation pile self-balancing static load test after grouting and grouting test mold, such as Figure 8-11As shown, it is composed of a bottom plate 20, a side plate 21, a partition plate 3, a connecting bolt 4, a filter plate 5, and a cover plate 6; there are two side plates 21, and vertical grooves 23 are provided on the opposite surfaces of the two side plates 21. and the horizontal groove 24, the horizontal groove 24 is axially perpendicular to the vertical groove 23, and is located at the bottom of the vertical groove 23; the bottom plate 20 is inserted in the horizontal groove 24, that is, the thickness of the bottom plate 20 is the same as The width is adapted. There is a groove 22 on the bottom plate 20. The width...

Abstract

The invention relates to a slurry injecting and fetching test mold, in particular to a slurry injecting and fetching test mold used after a self-balancing static load test of a foundation pile, and belongs to the building structure field. The slurry injecting and fetching test mold used after the self-balancing static load test of the foundation pile comprises a mold for containing slurry, whereina filter plate is arranged on the upper portion of the mold, the filter plate comprises a bottom plate and an enclosure, the shape of the bottom plate is adaptive to the inner diameter of the mold, ahole is formed in the bottom plate, and used for injecting the slurry into the mold, and the enclosure is arranged around the edge of the bottom plate, and is higher than the upper surface of the bottom plate. The slurry injecting and fetching test mold used after the self-balancing static load test of the foundation pile has the following advantages of 1, designing the filter plate, being capable of separating water generated in the isolation process of the slurry, guaranteeing the strength and the size of a test block below the filtering plate, and meeting test requirements; 2, being smallin occupied area and convenient to carry; and 3, being capable of sealing the upper end, convenient to transport, and capable of preventing the slurry from sprinkling in the transportation process.

Description

technical field [0001] The invention relates to a grouting and grouting trial mold, in particular to a grouting and grouting trial mold applied to a self-balancing static load test of foundation piles, and belongs to the field of building structures. Background technique [0002] At present, the test molds used for grouting after the self-balancing static load test of the foundation pile are all molds used in the laboratory in the past. The bottom area is large, takes up space, and the upper end is open, so it is inconvenient to carry, transport and maintain outdoors. Moreover, the water generated during the slurry segregation process accumulates on the upper part of the test piece, which causes the size and strength of the test piece to deviate from the test requirements and affects the test results. Contents of the invention [0003] The purpose of the present invention is to provide a kind of can avoid the size and strength of test piece and test requirement to produce ...
