Abstract
A foundation pouring apparatus A comprises: a pressurizing part 1 provided with pressurizing pouring liquid 5; a conduit 6 for sending the pressurizing pouring liquid to pipe 2; a retracting part 7 and a pressure gauge 8 in the low flow side and / or a flowmeter 9; and a control device 10 sending command to the retracting part based on the pressure and flow information. The method of using the device A, when the pouring liquid is poured from the pressurizing part to the foundation by the conduit and pipe, sending the retracting command to the retracting part, the output quantity and pressure of the pouring liquid are adjusted respectively corresponding to the pouring condition in the pipe. The invention can make each pipe ensure preconcerted pressure and output quantity, however the pouring pressure changes or impregnating impedance pressure of a plurality of pouring pipes outlet are different or one part of a plurality of pouring pipes stops pouring, also the corresponding pouring condition of the output quantity of each pipe during pouring can be adjusted, in addition, however the gelating solution pouring liquid or the suspension pouring liquid all can ensure non-compensating with good construction performance by the retracting part adjusting device.
Description
technical field [0001] The present invention relates to a foundation pouring device and a pouring method for pouring foundation pouring liquid into the foundation through a pouring pipe arranged in the foundation to carry out foundation reinforcement, especially relates to pouring with a predetermined output volume regardless of pressure changes during pouring, and can A ground pouring device and a pouring method that can adjust the output volume arbitrarily according to the input situation. Specifically, it relates to a foundation pouring device and a pouring method that adjusts the shrinkage of the cross-section of the conduit that delivers the foundation perfusate to the perfusion pipeline, so that the perfusate can be perfused according to a predetermined output. Background technique [0002] As a ground improvement technique for injecting perfusion liquid into the foundation and improving the foundation, the common method in the past is to install perfusion pipes in the...
