FIELD: construction.
SUBSTANCE: invention relates to construction, namely, to drive metal sheet piles into earth, and more specifically to control of quality of the specified process, related to rupture (opening) of a lock joint at depth. The method to control opening of a lock joint of sheet piles consists in driving a sheet pile into earth, and the sheet pile has locks with the inner cavity, and submersion of the next sheet pile into the earth. Prior to driving of piles into soil to the inner cavity of the metal sheet pile, at the side of pile insertion into soil, they place a signal device with source of oscillations with varied frequency, at the same time period of signalling device operation exceeds the time of pile driving. The pile is driven, the receiver of oscillations is installed on the upper end of the pile, and the signal is received from the source of oscillations. Prior to driving of the next sheet pile on the inner side of the free lock they install a signalling device, comprising a wedge-shaped body facing with a sharp end down, on which at the side of the short cathetus there is a source of oscillations. When the next pile is driven, its lock, as the signalling device placement depth reaches the previous pile by the edge of its inner cavity, breaks the source of oscillations, and oscillations are no longer accepted by the receiver, which means that the lock of the specific pair of metal sheet piles during submersion does not open. If when the next pile is submerged to the depth of installation of the signalling device at the next pile the receipt of oscillations continues, it means the lock joint of this pair of sheet piles in the soil thickness broke (opened).
EFFECT: provision of detection of a break (an opening) in depth of soil of lock joints of metal sheet piles during their submersion.
3 cl, 1 dwg
The invention relates to a method for driving into the ground metal sheet piles, and more specifically to the quality control of this process, associated with the gap (difference) locking joint depth.
For the device of sheet pile walls are most commonly used profiles, which differ in cross-section, the device of the castle and its location relative to the profile. The tongue can be Z - and U-shaped profile. In addition, when the driving of sheet piling in castles deformations are generated, and efforts may increase to such values that will happen gap sportowego connection at some depth (Device pits and dewatering. Knaupe Century. TRANS. with it. Mthobisi; edited Vinsure.com, Van. - M.: stroiizdat, 1988. - 376 C., Il.). One way to prevent rupture, is to eliminate the ingress of soil into the internal cavity of locks connected between a metal sheet piles.
Known invention (Moulin J.-M., RIX A. Method fixed connection sheet piles. Patent of the Russian Federation No. 2262572), in which the gap between the locks of metal sheet piles formed by a longitudinal groove in the head of one of the castle and the internal cavity of another castle, lower welding electrode and weld in the gap between the locks of metal sheet piles.
Known is also taken as a prototype method for driving into the ground spotboy piles (Moulin J.-M., RIX A. Method of driving sheet piles and apparatus for closing and sealing the internal cavity of the castle spotboy piles. Patent of the Russian Federation No. 2254416), which uses at least one lock with an internal cavity in which to clogging spotboy piles into the ground insert a closing device in the form of a pipe, providing for subsequent extraction of the tube from the inside of the castle and dive into the ground next metal spotboy piles to the castle, and prior to the installation spotboy piles into the ground, inflate the tube and seal the open longitudinal slot of the inner cavity of the castle, and to retrieve the inflatable tube from the inside of the castle spotboy piles pipe down. Device for closing and sealing the internal cavity of the castle metal spotboy pile is placed into the internal cavity of the lock tube. The technical result of the invention consists in the protection of the internal cavity of the castle spotboy piles from exposure to soil through the closing device.
The disadvantage of these methods is the remaining possibility of rupture (divergence) sheet metal compounds in the piling in heterogeneous soils. This grunt and the permeability of the castle compounds may increase in cases, when in the process of driving the pile hits necropsia incorporation into the soil (boulders and other), which might result in a bounce castle one element from another castle, the twisting of the tongue or lock.
Methods of identifying such gaps (differences) at a depth not found.
The aim of the invention is the detection of the gap (differences) in the depths of the castle ground connections sheet piles when they dive.
The technical result is the placement on the inner side of the interlocking connection of the metal spotboy piles signaling devices that establish the fact of newscalifornia castle adjacent metal sheet piles, by determining the moment of attainment score pile a certain depth.
The construction of the signal device and circuit implementation of the proposed method is shown in figure 1, where indicated:
1 - warning device,
2 wedge - shaped body,
3, a source of oscillations of frequency variation,
4 - mount,
5 - metal tongue-and-groove pile,
6 - lock with an internal cavity,
7 - the following is a Groovy pile,
8 receiver hesitation.
The method is as follows.
Before driving piles into the ground on the inner cavity of the lock (6) metal spotboy piles (5) with the bracket (4), which is in the form of a welded or adhesive seam-side occurrences of piles into the ground size is up warning device, which contains turned downwards wedge-shaped housing (2)on which side of the short leg (2A) is placed a source of oscillations of frequency variation (3). The V-body long leg (2B) is connected by a bracket (4) from the pile (5). The time signal of the device exceeds the time of driving piles. The pile hammer in a known manner, set the receiver variations (8) on the upper end of the pile and take the signal from the vibration source (3). Before driving the next spotboy piles on the inner side of the free castle set warning device (1).
When driving the specified next pile (7) lock (6) upon reaching the depth of placement of the signal device of the previous pile edge of its inner cavity splits the source of vibrations (3) and receiving vibrations receiver (8) is terminated. This fact suggests that the castle particular pair of metal sheet piles when diving is not dispersed. If you dive a piling to a depth of placement of warning devices at the previous pile reception oscillation continues, this indicates the gap (difference) locking connection between a given pair of sheet piles in the soil column.
1. The method of controlling the divergence of the interlocking connection of the sheet piles, which consists in hammering into the ground spotboy piles with Sakis internal cavity, dive into the ground next spotboy piles with locks, characterized in that prior to driving piles into the ground on the inner cavity of the castle metal spotboy piles, from occurrences of piles in the ground, place a warning device with a source of oscillations of frequency variation, at the same time signaling device exceeds the time of driving of piles, pile hammer, install the receiver oscillations on the upper end of the pile and take the signal from the vibration source, and before driving the next spotboy piles on the inner side of the free lock set signal device containing facing downwards wedge-shaped body on which side of the short leg posted by the source of vibrations, and when driving a piling her castle when you reach a depth of placement of the signal device of the previous pile edge of its inner cavity divides the vibration source and receiving vibrations receiver stops, which suggests that the castle particular pair of metal sheet piles at the dive did not, however, if you dive a piling to a depth of placement of warning devices at the previous pile reception oscillation continues, this indicates the gap (difference) locking connection between a given pair of sheet piles in tamegroute.
2. The signaling device according to claim 1, characterized in that the long leg of the housing of the alarm device is connected with the inner side of the castle piles using the attachment.
3. Warning device according to claim 2, characterized in that the attachment is made in the form of a welded or adhesive joint.
