Detailed Description
A tunnel secondary lining vault concrete longitudinal continuous pouring construction method comprises the following steps:
s100, measuring and lofting, wherein a measurer releases the position of the central line of the inner outline tunnel of the secondary lining of the tunnel, determines the positioning elevation of the trolley, and guides the site trolley to be in place according to the designed position.
S200, walking, positioning and reinforcing the secondary lining trolley, walking the secondary lining trolley to a design position of a secondary lining profile of the tunnel according to the field measurement condition, positioning under the guidance of a measuring person, and reinforcing the secondary lining trolley and setting and reinforcing a secondary lining end head die of the tunnel after the positioning is finished.
S300, longitudinally and continuously pouring a trolley into position; the longitudinal pouring concrete gun of the pouring trolley is conveyed to the bottom of the end of the two lining ends by the pouring travelling trolley in the longitudinal direction, and the visual monitoring system and the concrete pressure detection sensor are installed on the longitudinal pouring concrete gun.
S400, pouring concrete of the two lining side walls; and (3) adopting a two-lining trolley to pour layer by layer window by window, feeding materials layer by layer window by window, symmetrically pouring partial concrete of the two lining side walls, and pouring layer by layer and vibrating and compacting layer by layer.
S500-after the concrete of the two lining side walls is poured and vibrated layer by layer window by window, the concrete pump pipe interface is replaced to a longitudinal continuous pouring trolley for longitudinal pouring.
S600, starting a concrete delivery pump, starting longitudinal continuous pouring of the concrete with the two lining vault tops, and enabling a longitudinal pouring concrete gun to move back and forth every 5 minutes in the pouring process to ensure that the longitudinal pouring concrete can freely move in the concrete.
S700-pouring second-lining vault concrete longitudinally and continuously in a retreating mode; when concrete is poured to the high position of the arch top of the secondary lining of the tunnel, detecting the pressure of the concrete backing flooding wrapping pouring gun through a concrete pressure sensor, and backing the longitudinal pouring concrete gun according to the step pitch of 0.6 m; and (3) starting the two-lining trolley attached vibrators one by one in the filling process, and carrying out layering and regional vibration compaction on the two-lining concrete until the two-lining concrete is fully filled.
S800, exiting the station to clean the pipeline, and finishing the filling; and cleaning the longitudinal poured concrete pipeline by using a piston, driving the longitudinal continuous pouring trolley to exit the station, and finishing the longitudinal continuous pouring of the concrete with the two lining vault tops.
S900-RPC belt mold pressing slurry; and after the secondary lining concrete is poured for 2 hours, hole-by-hole tape mold grouting is carried out on the vault of the secondary lining by using RPC pipe tape mold grouting until the grouting hole and the exhaust hole are plugged after the slurry overflows from the end of the secondary lining, the grouting system is dismantled, and grouting is finished.
In the step S300, the distance between the tip of the longitudinal concrete pouring gun and the top of the upper plate or the bottom of the two lining tips is 60 cm. The method aims to ensure that the concrete has certain degree of freedom after entering a mould from a longitudinal pouring gun, and meanwhile, when the concrete is continuously poured to the arch crown high position, the pouring gun can be quickly wrapped to form a pile base layer which is reversely backfilled and wraps the natural gradient of the concrete required by flooding type pouring, so that a principle foundation is formed for a longitudinal continuous pouring process, and the subsequent process of the process is realized; if the distance is too large, the principle foundation is not formed quickly, and the failure of the longitudinal continuous perfusion process is easily caused; if the distance is too small, the degree of freedom of the concrete entering the mold is too small, and the early formation principle foundation can cause that the concrete at the end of the two lining ends is not easy to fill compactly, so that the problems of void, insufficient thickness or non-compact quality are formed.
In the step S500, in the longitudinal pouring process, the performance of the on-site second-lining vault concrete needs to be detected, and the slump of the concrete entering the mold needs to be controlled to 170 mm-190 mm. The slump control of the concrete entering the mould is a control range determined by repeated contrast tests, the concrete entering the mould with different slump is prepared one by one according to the performance requirements of the railway concrete construction quality acceptance standard on the concrete of the second liner, the contrast tests are respectively carried out, and the concrete entering the mould can form a stable concrete natural slope accumulation layer by finally determining that the concrete entering the mould can form the stable concrete natural slope accumulation layer when the slump of the concrete entering the mould is 170-190 mm through actual observation by taking whether the stable concrete natural slope accumulation layer can be formed in the longitudinal continuous pouring process. The performance of the concrete is a key factor of process success or failure, and the control of the cohesiveness, the workability and the slump of the concrete determines whether the process can form a natural gradient accumulation layer of the concrete, so that a back-pressure backfill package flooding type continuous retreat pouring is formed by wrapping a longitudinal pouring concrete gun. The pouring mode is that after the longitudinal continuous pouring process is switched, when the concrete entering the mould needs to meet the process requirement performance, the concrete enters the space of the two lining arch parts from the longitudinal pouring gun, and forms concrete stacking layer according to a certain natural gradient under the action of gravity, and the concrete stacking layer gradually extends and stacks to the arch top high position along with the continuous pouring of the concrete, and gradually wraps the longitudinal pouring gun; at the moment, the end of the filling gun is buried in the concrete, the concrete is continuously filled through the filling gun, the concrete is extruded out from the inside of the accumulation layer, and a space of the two lining arches is backfilled by back pressure; along with the continuous filling of the longitudinal continuous filling process, the concrete stacking layer filled with the space of the two lining arches gradually retreats in a flooding mode, the length of the wrapped longitudinal continuous filling gun is longer and longer, in order to ensure that the longitudinal filling gun can move freely and be pulled out, when the length of the flooded wrapped filling gun is detected by a pressure sensor to exceed 1m, the longitudinal continuous filling gun retreats in time at a step distance of 0.6m, and the longitudinal filling gun is ensured to be always buried in the concrete with the length not less than 1m before the process pipe drawing is finally completed; and the longitudinal concrete pouring gun is buried in the concrete all the time in the pouring process, so that the inside of the poured concrete is kept to be poured under pressure until the longitudinal continuous pouring is finished. The two-lining vault concrete longitudinal continuous pouring construction process needs to strictly control the raw material quality and the construction mix proportion of concrete, the raw material of the concrete needs to meet the requirements of the railway concrete construction quality acceptance standard, the construction mix proportion needs to be implemented according to the concrete mix proportion determined and approved by tests strictly, and the slump of the concrete entering a mold is controlled to be 170-190 mm.
In the step S600, the longitudinal concrete pouring gun is buried in the concrete during the pouring process, so as to ensure that the inside of the poured concrete is kept poured under pressure.
