Embodiment Construction
[0033] When pre-filled at the factory, the connecting tube presses figure 1 The sealing section 2 is set and connected with a transparent joint 3; the end of the sealing section 2 is provided with a terminal joint 4.
[0034] In this embodiment, the polyurethane transparent tube 1 is used as the pre-injection liquid connecting pipe section used in the measurement site, and the inner diameter is between 10 and 20 mm. The models of the transparent joint 3 and the end joint 4 are consistent with those of the liquid injection joint 5 of the pre-filled transparent box to facilitate connection.
[0035] The pre-fill liquid transparent box of the factory pre-fill liquid is the same as the on-site public liquid tank, such as figure 2 , 3 , 4, and 5.
[0036] Transparent casing box wall 11 selects transparent plastics or plexiglass for use. The transparent box is divided into an upper layer and a lower layer structure, and the top layer of the upper layer is open. Between the bot...

The invention discloses a liquid pre-injection communicating pipe device for a hydrostatic leveling instrument, and a liquid injection method and a measurement method of the liquid pre-injection communicating pipe device. The liquid pre-injection communicating pipe device comprises liquid pre-injection communicating pipes and a liquid pre-injection device, wherein each liquid pre-injection communicating pipe comprises a transparent liquid pre-injection pipe main body, and the two ends of each transparent liquid pre-injection pipe main body are respectively connected with a sealing section by a transparent joint; the liquid pre-injection device comprises a transparent box body with an upper layer and a lower layer; the box body is capable of controlling liquid injection speed. After field installation is finished, settlement measurement is carried out by enabling all liquid pre-injection pipes to be in parallel connection with the transparent box body. The communicating pipes of the liquid pre-injection communicating pipe device can effectively remove air in the pipes during liquid pre-injection in a factory. After field installation is finished, the communicating pipes are connected in parallel, so that the mutual interference among all the communicating pipes can be reduced, and the accuracy of results is guaranteed; the liquid pre-injection communicating pipe device is convenient to operate, thus having a wider application prospect.
Description
technical field [0001] The invention relates to a pre-injection liquid connecting pipe used for static level measurement and its use method, which is mainly used to eliminate the influence of bubbles in the connecting pipe of the static level instrument that cannot be discharged in time and effectively on the installation efficiency of the measurement site and the influence of the air bubbles on the static level instrument. The problem of measurement interference belongs to the field of precision measurement of building settlement. Background technique [0002] In recent years, pile foundation underpinning technology has been widely used in the field of construction. After the underpinning is completed, the settlement of the pile and the underpinned column needs to be accurately measured, and the top of the column should be raised back to its original position according to the settlement to eliminate the damage to the building caused by uneven settlement. A general optical ...
