Description
Technical Field
The invention belongs to the field of protection tools for a pile foundation inclinometer pipe, and particularly relates to a pile foundation inclinometer pipe damage prevention protection device and a using method thereof.
Background
The inclinometer pipe (the cross section of which is shown in figure 7) is a measuring pipe which is embedded underground and used for observing the horizontal displacement inside the soil body, and the inclinometer pipe is embedded into the pile foundation through a pile foundation reinforcement cage in a common embedding mode. The pile is a force transmission component which transmits all or part of the load of a building to foundation soil and has certain rigidity and bending resistance, has the function of transmitting the load to a soil layer with good bearing performance deeper underground so as to meet the requirements of bearing capacity and settlement, and is a deep foundation form which is most widely applied. The sediment at the bottom of the pile and the impurities precipitated in the slurry during the pouring process form floating slurry with a certain thickness on the surface of the concrete during the pouring of the concrete, the floating slurry needs to be over-poured for a certain height during the pouring, and the higher parts are cut off after the foundation pit is excavated, so the construction is called as a pile breaking head (as shown in figure 6). The common construction modes of the broken pile head mainly include manual pile head breaking and mechanical pile head breaking, but in any form, when the pile foundation of the embedded inclinometer pipe is involved, the inclinometer pipe is extremely easy to damage, and the embedding yield is reduced. In addition, in the construction process of other processes after the pile head breaking process, the pipe body is damaged and blocked due to manual, mechanical construction, falling objects and other operations, so that in order to ensure effective monitoring, the drilling is further repaired and the inclinometer is buried again, and unnecessary construction period delay and economic loss are caused.
How to protect the inclined measuring pipe in the pile head breaking process, a common method comprises the following steps: a protection sleeve is arranged on the inclinometric tube and can be connected through bolts or clamps, and the protection sleeve is arranged at a pile head breaking construction position. The existing construction means has the following defects: 1. because the inclinometry pipe is of a hollow structure, the outer sheath is arranged outside the inclinometry pipe, when the outer sheath is subjected to transverse impact force, the inclinometry pipe still bears most of the impact force, and particularly the junction position of the protective sheath and the inclinometry pipe is easier to bend or deform; therefore, the outer sheath can only protect the wrapped position of the oblique measuring pipe from being scratched, but the junction of the oblique measuring pipe and the outer sheath is still easily damaged by impact. 2. The outer sheath is generally mounted on the inclinometer pipe by using bolts or clamps, and in order to prevent the outer sheath from sliding off, a large torque needs to be applied, so that the inclinometer pipe is easily crushed.
