Detailed description of the invention
Below in conjunction with accompanying drawing illustratively the utility model.
Combined steel plate pile as shown in Figure 1, comprises H profile steel plate 1 and U-shaped steel plate 2, and the wing plate 3 of H profile steel plate 1 has pipe 5 structure, and U-shaped steel plate 2 has round steel 6 structure, and the buckle structure 4 that H profile steel plate 1 is formed by pipe 5 and round steel 6 with U-shaped steel plate 2 is connected.
As shown in Figure 2, the spacing d of pipe 5 and round steel 6 is 6 ~ 8mm to buckle structure.
The specific design combined steel plate pile of 7 kinds of different spacing d, spacing d is respectively 5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 9mm.Often kind of combined steel plate pile H profile steel plate 20, U-shaped steel plate 19.To construct in identical soft soil layer water-stop curtain supporting with above-mentioned 7 kinds of combined steel plate piles respectively, investigate " with stake " phenomenon, operating procedure is as follows:
(1) levelling of the land: make place as far as possible smooth, to improve the efficiency of adjustment leading truck, ensures that there are enough intensity carrying leading truck deadweights in place simultaneously.
(2) install leading truck: lay leading truck, leading truck, when laying, utilizes level(l)ing device to make leading truck ensure planar horizontal, vertical up and down, error should be less than 5mm, and instrument or plumb bob can be utilized to carry out controlling (diagonal angle, two ends hanging wire is hammered into shape, can control up and down and level).
(3) H profile steel sheet pile is installed: first sling by H profile steel plate by the upper and lower two-layer H profile steel plate pilot hole of leading truck, do not bury, the location that means for adjusting limit of movement carries out H profile steel plate is utilized before burying, movable sheave in all means for adjusting limit of movements is all tightened up and withstands H profile steel plate, after bilevel pulley all tightens up and puts in place, slightly unclamp movable sheave, make to keep in touch face just between pulley and H profile steel plate, lifting machine hung H profile steel plate will keep stable as far as possible period, rocking of first mate can not be had, when everything in readiness, start lower H profile steel plate, first by H profile steel plate deadweight pile sinking, when continuing to sink, vibrating hammer is utilized to clamp H profile steel plate top vibration-sunk, in vibration-sunk process, the subsidence velocity of H profile steel plate can not be too fast, about about 2 ~ 3m per minute should be remained on, under vibration in heavy process, the change of movable pulley will be noted the moment, movable pulley face should be kept in the moment to touch H profile steel plate, keep rotating.When H profile steel panel vibration is to leading truck upper strata 0.6 ~ 0.8m, stops vibration, start the construction of next H type stake.The verticality of H profile steel plate strictly will be controlled when H profile steel sheet pile is installed.
(4) U-shaped steel sheet pile is installed: after the construction of H profile steel plate, start U-shaped steel sheet pile of constructing.Before construction, the round steel of U-shaped steel plate both sides should cut into an oblique angle, and coats butter, the frictional force of minimizing and round steel and pipe.During contraposition, if when U-shaped steel plate is greater than or less than H profile steel sheet pile spacing, can knocking with the iron hammer of 12P, making U-shaped steel plate to entering in H profile steel plate pipe.After U-shaped steel plate both sides round steel all enters H profile steel plate pipe, the gravity of self should be leaned on to do free pile sinking, period loop wheel machine and commander should note coordinate, moment adjustment loop wheel machine direction, allows U-shaped steel plate can freely smoothly by the upper and lower two-layer U-shaped steel plate pilot hole of leading truck, and a part of burying, when after burying no longer pile sinking time, start vibration-sunk, vibration processes can not be fast, keeps about 2 ~ 3m per minute.
Observe the different combined steel plate pile of 7 kinds of spacing when installing U-shaped steel sheet pile, whether H profile steel sheet pile can there is " with stake " phenomenon.The criterion of " with stake ": 1. serious: H profile steel sheet pile sinks with identical speed along with the sinking of U shaped steel plate pile; 2. general: H profile steel sheet pile sinks with relatively slow speed along with the sinking of U shaped steel plate pile.When " with stake " phenomenon is serious, construction should be stopped immediately, take measures to eliminate or can continue after slowing down; When " with stake " phenomenon is general, then can continue construction.Combined steel plate pile " with stake " the phenomenon statistics that 7 kinds of spacing are different is shown in form 1.
7 kinds of combined steel plate pile " with stake " phenomenon statistics that table 1 spacing is different
As can be seen from Table 1, when 6 ~ 8mm, all there is not serious " with stake " phenomenon in the spacing d between pipe and round steel, and especially when spacing d is 7.5mm, construction is the most smooth, and " with stake " phenomenon does not occur; Serious " with stake " phenomenon is all there occurs when spacing d is 5mm or 9mm.Comparing result shows, spacing d is excessive or too small serious " with stake " phenomenon all easily occurs.Because the frictional resistance between round steel and pipe enlarges markedly when spacing is too small, may be because pipe can not well assist leading truck to fix round steel when spacing is excessive, cause U-shaped steel plate generation deflection, the frictional resistance after deflection between round steel and pipe also obviously increases, and occurs " with stake ".
