Embodiment Construction

[0015] The invention relates to a position measuring device for a concrete feeding conduit used in the construction of an underwater cast-in-place pile. During the construction of the cast-in-place pile, it is fixed at an appropriate position above the outlet of the concrete feeding conduit for pouring the cavity of the cast-in-situ pile, and the pressure of the fluid medium is obtained. The information is used to determine the position range of the interface between the concrete and the slurry layer in the cavity, which is used to assist in guiding the construction of the underwater cast-in-place pile.

[0016] Depend on figure 1 It can be seen that the device is composed of a sensing unit 100 and a display control unit 200 connected to the sensing unit; the sensing unit 100 includes five surface pressure sensing sensors 111, 112, 113, 114, and 115. The sensors are installed on the mounting frame 102 of the sensor unit 100 at a distance of 1 meter. The mounting frame 102 is f...

Abstract

The invention discloses a concrete feed delivery pipe position measuring device for underwater filling pile construction. The concrete feed delivery pipe position measuring device includes a sensing unit and a display control unit; the sensing unit includes a plurality of surface pressure sensors, wherein the surface pressure sensors are mounted on a mounting frame in a fixed-spaced mode from thebottom to the top, the mounting frame is fixedly connected to two or more welding blocks through bolts, and the welding blocks are welded to the outer wall above a discharging hole of the concrete feed delivery pipe from the bottom to the top; and the surface pressure sensors are connected in series and then connected to the display control unit. The concrete feed delivery pipe position measuringdevice has the beneficial effects that in the operation process of the underwater concrete filling pile, operators in the site can be effectively guided to complete lowering and lifting operation of the concrete feed delivery pipe, and the actions that quality is ensured, and construction accidents are avoided are achieved.

Description

technical field [0001] The invention relates to the technical field of concrete pouring construction, in particular to a position measuring device for a concrete feeding conduit used for underwater pouring pile construction. Background technique [0002] In the construction process of underwater pouring concrete piles, the concrete conveying conduit method is generally used for pouring, that is, the concrete mixture passes through the lower opening of the concrete conveying conduit and enters the bottom of the initially poured concrete (as a water-resisting layer), and the newly poured Concrete is supported by an underwater concrete pouring method in which the initial poured concrete rises and expands to the periphery. The concrete at the bottom of the first poured pile is gradually lifted to the pile head by the subsequent concrete, so the concrete at the head of the underwater cast-in-situ pile is always the part that is poured first. Affected by pile bottom sediment, ret...
