AI Technical Summary

Technical Problem

During the sealing process of underwater grouting specimens, the rubber sealing ring is prone to tilting or twisting, resulting in unreliable sealing, frequent leakage of pressurized water, and affecting the test results.

Method used

A rubber ring, rubber sleeve, and gasket are installed at the bottom of the grout sample. The rubber sleeve limits the position and the adhesive enhances the stability of the rubber ring. Combined with the guide opening and rough slope for guidance, the rubber ring is ensured to roll and wrap smoothly, and the diameter is increased to improve the sealing effect.

Benefits of technology

This effectively reduces leakage of the rubber ring between the grouting body and the fixed mold, improves the sealing effect, and ensures the normal progress of the underwater grouting test.

Abstract

本实用新型提供一种水下灌浆质量检测试验装置，涉及水下灌浆领域，包括固定模具以及灌浆体样本，灌浆体样本底部安装有用于和固定模具密封的卷曲部，卷曲部包括包覆在灌浆体外侧的橡胶圈和橡胶套以及对橡胶套限位的垫圈，垫圈设置于灌浆体样本的底部，通过设置在灌浆体样本底部的橡胶圈、橡胶套以及垫圈，使得橡胶圈可以准确的套设在灌浆体样本外侧，减少橡胶圈套设在灌浆体样本外侧时发生较大倾斜而产生扭曲导致泄露的现象，安装橡胶圈时，橡胶圈会带动橡胶套缠绕在橡胶圈外侧，增加橡胶圈的直径，从而可以提高橡胶圈在灌浆体样本和固定模具之间的密封效果，减少泄露现象。

Claims

1. An underwater grouting quality test device comprising a fixed mold (1) and a grout body sample (2), characterized in that: The bottom of the grout sample (2) is equipped with a curled part for sealing with the fixed mold (1). The curled part includes a rubber ring (3) and a rubber sleeve (4) covering the outside of the grout, and a gasket (5) for limiting the rubber sleeve (4). The gasket (5) is located at the bottom of the grout sample (2). After the grout sample (2) is completely installed inside the fixed mold (1), the rubber sleeve (4) curls up and covers the surface of the rubber ring (3).

2. The quality test device for underwater grouting according to claim 1, characterized in that: The rubber ring (3) is fixedly connected to the top of the rubber sleeve (4), and the diameter of the rubber ring (3) is larger than the diameter of the rubber sleeve (4).

3. The quality test device for underwater grouting according to claim 2, characterized in that: The outer surface of the rubber sleeve (4) is coated with adhesive.

4. The quality test device for underwater grouting according to claim 1, characterized in that: A guide opening (6) is provided around the bottom of the fixed mold (1). When the rubber ring (3) moves towards the inside of the fixed mold (1) along with the grout sample (2), the rubber ring (3) first comes into contact with the guide opening (6).

5. The quality test device for underwater grouting according to claim 1, characterized in that: The surface of the guide opening (6) is a rough slope.

6. The quality test device for underwater grouting according to claim 1, characterized in that: The inner diameter of the fixed mold (1) is larger than the diameter of the grout sample (2).
