Abstract:
Provided is a variable-pitch wall forming device for a press-fit type underground diaphragm wall, comprising a wall shoe ( 3 ), vibration chambers ( 4 ), a fixed-pitch box ( 1 ) and a variable-pitch box ( 2 ), wherein the variable-pitch box ( 2 ) is installed in the fixed-pitch box ( 1 ), the wall shoe ( 3 ) is installed on the bottom of the variable-pitch box ( 2 ) and the fixed-pitch box ( 1 ), and the vibration chambers ( 4 ) are provided on a side wall of the fixed-pitch box ( 1 ) and a side wall of the variable-pitch box ( 2 ). Also provided is a method of variable-pitch wall forming for a press-fit type underground diaphragm wall.

Claim (Index 7):
The variable-pitch wall-forming device according to  claim 1 , wherein the device comprises the principle and application of variable pitch adjustment, prefabricated wall boots, mechanical connection and closure of three process steps: (1) the principles of variable pitch control and application process steps: According to the actual distance between the two wall-forming devices that have been squeezed into the ground before and after, The drawer box ( 22 ) is moved to the right place to start assembly; if the actual distance between the two wall-mounted devices that have been squeezed into the ground is finely adjusted within the drawer box ( 22 ), only the drawer box ( 22 ), There is no need to add the assembled outer box body ( 7 \u2032). Therefore, the drawer box ( 22 ) and the vibration board ( 21 ) have fine pitch characteristics of arbitrary pitch variation. By mastering this characteristic, the fixed size outer box body  7 \u2032) and the vibrating plate ( 21 )+the drawer box ( 22 ) can be combined to form a pitch changing wall device capable of adapting to ten million pitch values. (2) The wall boots ( 3 ) are prefabricated in advance. Process steps: 3) is based on the final total length of the bottom wall of the device into the wall to produce the total axial size, in advance and can not accurately grasp the value, but in actual use in order to maintain continuous operation on the need to advance precast; empirically estimated wall boots ( 3 ) Axial dimensions, prefabricated when the step ( 26 ) section should not be large, The cross-section does not affect the use of large effect, increasing the squeeze into the end of the area can be ignored; and slope ( 25 ) section should be small and should not be large, slope ( 25 ) Cavity is difficult or impossible, and the section is small enough to be filled with dry hard concrete or other filling material; (3) mechanical connection closure: when the variable pitch wall-mounted drawer box ( 22 ) moves axially, the short side  23 ) is moved along with the short side ( 23 ) in the drawer box body ( 5 ) cavity position is not fixed, first of all to be solved is based on the main body ( 5 ) and drawer short side Cavity size Produce two reinforced cages, respectively, placed in the main body ( 5 ) and drawer box ( 22 ) of the two cavities to increase the rigidity of the wall included in the calculation, variable pitch wall device as crowded into the wall when the final encirclement of the machinery Connecting device, which is to be connected at one end of the first squeeze into the closed wall device, the other end is squeezed into the ordinary wall device; need to grasp the correct process sequence: the first step, on the same axis, will pitch Wall-mounted device dovetail convex track ( 11 ) can only be aimed at closing the wall device dovetail groove ( 10 ), and change The dovetail groove ( 10 ) of the walling device can only be aligned with the dove-tail convex track ( 11 ) of the adjacent final walling device; in the second step, the walling device will be turned into two devices Underground wall into the device connector and gradually squeezed into the ground to a predetermined depth, so the final squeeze into the wall around the mechanical connection process is completed; the first step, first pouring the first closed concrete wall device and gradually pulled out, Step 4, and then pour the other end of the final into the ordinary wall into the concrete device and gradually pulled out, the fifth step, the final pouring into the concrete wall device and gradually pull out into the wall eventually gapless connection.
