Detailed Description
The structure of the liquid injection pipeline of the combined load box of the present invention will be further described with reference to fig. 1 to 2.
The utility model provides a liquid injection pipeline structure of combined load case, characterized by: comprises a loading unit 1 and a pipeline 2;
the loading unit 1 is prior art, so the specific structure thereof will not be described in detail in this embodiment.
The loading unit 1 is provided with a plurality of loading units, each loading unit 1 is provided with an upper interface 5 and a lower interface 6, and the upper interfaces 5 and the lower interfaces 6 are communicated with a loading cavity 11 of the loading unit 1.
The plurality of loading units 1 are sequentially connected through a pipeline, that is, the loading chambers 11 of the plurality of loading units 1 are sequentially communicated through the pipeline 2, and the lower interface 6 of the previous loading unit 1 is connected with the upper interface 5 of the next loading unit 1.
The pipelines at the head and the tail are respectively provided with a switch valve and are respectively a loading pipeline 3 and a grouting pipeline 4, namely, the pipeline connected with the upper interface 5 of the first loading unit 1 is the loading pipeline 3, and the pipeline connected with the lower interface 6 of the last loading unit 1 is the grouting pipeline 4.
In operation, the loading pipeline 3 and the grouting pipeline 4 both extend to the ground; by utilizing the loading pipeline 3, loading liquid can be introduced into the loading units 1 which are connected in sequence to realize loading operation, and in the embodiment, the loading liquid is water; after loading is finished, slurry can be introduced into the opened loading units 1 through the grouting pipeline 4 so as to ensure the structural strength of each loading unit after a balanced static load test; on the other hand, in the loading process, loading liquid enters the loading cavity 11 through the upper interface 5, in the grouting process, slurry is introduced into the loading cavity 11 through the lower interface 6, and meanwhile, the lower interface 6 is positioned below the upper interface 5, so that the slurry is introduced and filled from bottom to top in the loading cavity, the introduction mode is convenient for the slurry to completely discharge the loading liquid out of the loading cavity, and the slurry is enabled to completely fill the loading cavity, namely, the loading liquid is refluxed and discharged through a loading pipeline, and the structural strength of the loading box after a balanced static load test is obviously improved; in this embodiment, the slurry is cement slurry or other engineering medium.
In this embodiment, the ooff valve is the stop valve, and in the loading process, the stop valve locking on the slip casting pipeline 4, at the in-process of slip casting, after observing loading liquid and flowing out from the loading pipeline, the stop valve on the locking loading pipeline 3 to continue the slip casting pressurization to required pressure, close the stop valve on the slip casting pipeline 4 again. In this embodiment, the switch valve is located at the position where the loading pipeline and the grouting pipeline extend to the ground
The embodiment is further configured as follows: each loading unit 1 has a loading chamber 11 therein, each loading chamber has an upper slurry chamber 111 and a lower guide section 112, and the diameter of the upper slurry chamber 111 is larger than that of the lower guide section 112. With this structure, the piston rod 12 and the inner wall of the upper slurry chamber 111 can form a gap 13, which allows the loading liquid to flow to the lower port 6, so that the height of the position where the port 6 is disposed on the loading unit 1 can be lowered, so that an optimal height difference is formed between the upper port 5 and the lower port 6, and an optimal discharging effect of the loading liquid is achieved.
The embodiment is further configured as follows: the loading unit 1 has a cover plate 14, the lower surface of the cover plate has a ring groove 141, and the upper interface 5 is communicated with the ring groove. This setting can make the loading liquid enter into the loading chamber after, reduces the impact force of adding the carrier liquid under the effect of annular to can evenly fill the loading chamber through this annular, with reach even extrusion effect to piston rod 12, thereby make loading unit 1 open steadily.
