> Sand barrel type temporary support
uses dry fine sand in a closed container. It is easy to open the opening at the bottom or side of the container. The outflow then reduces the volume of fine sand in the container and is designed based on the principle of making the pad above the fine sand drop. Fill a container with an open top with fine sand, and place a pad slightly smaller than the upper mouth of the container on it, so that it is higher than the upper mouth of the container (of course, the upper mouth of the container must be lower than the height of the permanent support). The beam is placed on the pad. When other processes are completed, the sand is released from the opening on the side of the sand barrel. The volume of the sand in the container decreases, and the beam then falls onto the permanent support.

Installation
> Since each sand barrel corresponds to each fixed position, it cannot be used in a disordered manner, resulting in an elevation error. After the sand barrel is installed, the elevation must be reviewed and measured. The beam can be hoisted only after the elevation is qualified. In order to ensure that the top surface of the sand cylinder is evenly stressed, a thick rubber skin should be placed on the top surface of the steel backing plate of the sand cylinder, so that the bottom of the beam can be closely and evenly attached to the sand cylinder.
>Construction technology of sand barrel type temporary bearing
>
In practical application, attention should be paid to the height of the temporary bearing
. After placing the girder, the surface of the pad on the temporary support
should be higher than the top surface of the permanent support, and it must have a height of ~, and the top surface of the sandbox should be lower than the permanent support~, The screw switch is a little lower in the middle of the sandbox and can be tilted upward to facilitate the flow of sand.
> Another point worth noting is that when the beam plate falls on the temporary support
the loose sand must settle to a certain height. If it is not controlled well, it will affect the beam erection construction. For this reason, during actual construction, we should observe the settlement of sand and count the sandbox-type temporary supports. After placing girders of different weights, the settlement amount of the supporting sand is required to accurately control the settlement of the sand. Add evenly fine sand. When erecting the beam, you only need to ensure that the bottom elevation of the beam (the elevation of the upper pad) is higher than the top elevation of the permanent support after the sand settles. The height of different cover beams can be adjusted based on the amount of sand in the sandbox.
> After other processes are completed, it is necessary to place the temporary support beam on the permanent support. Just turn on the screw switch on the side of the sandbox and tap it gently, and the sand will flow out. , the girder will fall to the permanent support due to its own weight as the sand in the sandbox decreases, which is convenient and simple.

Obama warned China not to push its elbows in maritime disputes. Agence France-Presse reported Obama's speech with this title on the same day. The article stated that Obama joined the South China Sea dispute on Monday and called on regional countries, especially China, to abide by the law. Obama said that the United States does not have any territorial claims in the South China Sea, but as a Pacific country, Washington calls on China and other countries to stop land reclamation. We believe that any party's land reclamation and aggressive behavior in that area will be counterproductive. According to reports, Obama pointed directly at China. He used a boxing foul gesture as a metaphor to ask China to stop pushing its elbows. Voice of America emphasized in its report that Obama made a gesture of pushing his elbows outward when he said this at the White House.
