The fluid is covered in the case 610 by the cover plate 620, and the fluid is prevented from being scattered.
In this embodiment, rubber guide plates 631 extend obliquely downward from two sides of the top of the breakwater 630; the rubber guide plate 631 is provided with a plurality of injection holes 632; the injection hole 632 is provided with a puncture 633. Because the fluid in sandbox 600 is of a great variety, when adopting liquid to carry out the sand pressure test, can have the bubble in the liquid, if bubble quantity is too much in sandbox 600, can lead to the volume reduction of the liquid that sandbox 600 can hold to influence the pressure of sandbox 600, and then can influence the precision when follow-up sand pressure test. Therefore, when liquid is injected into the sandbox 600, the injection pipe is directly inserted into the injection hole 632, the flow breaking prick is transversely arranged in the injection hole, when the liquid of the injection pipe flows into the injection hole, the liquid can be divided through the flow breaking prick, and when the liquid is divided, if air bubbles are contained in the liquid, the air flow is pierced by the flow breaking prick, so that the air bubbles are broken, the volume of the liquid injected into each sandbox 600 is ensured to be the same, and the accuracy of the sand pressure test is ensured.
