Abstract
The utility model discloses a Lassen steel sheet pile for foundation pit supporting and protecting construction, which comprises a steel sheet wall body and a supporting frame, wherein the cross section of the steel sheet wall body has a rectangular structure; the supporting frame is arranged in the steel sheet wall body; the supporting frame comprises a horizontal supporting rod and an inclined supporting rod; the horizontal supporting rod is supported in the middle of the two sides corresponding to the steel sheet wall body with the rectangular structure; and the two sides on the corresponding sides are respectively in fixed connection with the middle parts on the other two sides through the inclined supporting rod. According to the Lassen steel sheet pile provided by the utility model, the steel sheet wall body is used for stabilizing the soil on the periphery of a foundation pit, so that the whole stability is higher; and meanwhile, the underground water outside the foundation pit is prevented from seeping into the foundation pit, so that the waterproof effect is better; and during a construction process, an excavator and a piling manipulator are used as main power for sinking a Lassen pile, so that the speed for striking or pulling the Lassen steel sheet pile is high and the construction is convenient and quick.
Description
Technical field
The utility model relates to a kind of foundation pit support device, relates in particular to a kind of Larsen steel sheet pile that is used for foundation pit support construction.
Background technology
Owing to receive the constraint of complicated construction condition, when striding the lake bridge construction, should take comparatively safe support pattern.The bored pile pile foundation adopts builds the method construction of cofferdam, island; According to absolute altitude at the bottom of geological condition and the cushion cap, need during bearing platform construction than deep excavation, for guaranteeing security of foundation ditch construction; Reduce the large tracts of land excavation simultaneously as far as possible or put the slope; Cofferdam, island quality is built in assurance, so that the construction of follow-up upper tank beam full framing needs to adopt comparatively ripe safe cofferdam construction mode.
Pattern foundation pit supporting structure is as a working measure, and the convenience of considered safety, construction costs, duration, construction etc. are taken all factors into consideration on-the-spot conditions such as surrounding enviroment, road and soil layer combination.In the prior art, pattern foundation pit supporting structure mainly contains following dual mode: one, adopt and put sloping heavy excavation, put the gradient and must reach 1: 1.5 and can guarantee stability of slope, will build that the cofferdam, island is basic all to be destroyed, and have bigger potential safety hazard; Two, adopt the supporting of H shaped steel, globality is general, and stagnant water effect is too poor, brings big difficulty to construction.
The utility model content
To weak point of the prior art, the utility model provides foundation ditch periphery soil stabilization in a kind of guarantee work progress, stops the outer underground water of foundation ditch to infiltrate the Larsen steel sheet pile that is used for foundation pit support construction in the foundation ditch.
A kind of Larsen steel sheet pile that is used for foundation pit support construction that the utility model provides comprises that cross section is the steel plate enclosure wall body and the bracing frame that is arranged in this steel plate enclosure wall body of rectangular configuration; Support frame as described above comprises transverse support bar and oblique support bar, and said transverse support bar is supported on the middle part of corresponding both sides of the steel plate enclosure wall body of rectangular configuration, is fixedly connected through the middle part of oblique support bar with other both sides respectively on the both sides of this respective side.
A kind of preferred version as the utility model; Also comprise detachable connecting device; Said detachable connecting device comprises channel-section steel limiting plate that opening makes progress and the channel-section steel buckle that Open Side Down; Said channel-section steel limiting plate is fixed on the steel plate enclosure wall body, and the channel-section steel buckle is combined on the channel-section steel limiting plate through the bolt junction button, and the two ends of transverse support bar and oblique support bar are installed in respectively in the stopper slot of being made up of channel-section steel limiting plate and channel-section steel buckle.
The beneficial effect of the utility model is: the Larsen steel sheet pile of the utility model adopts steel plate enclosure wall body to stablize the foundation ditch periphery soil body, and resistance to overturning is stronger; Stop the outer underground water of foundation ditch to infiltrate in the foundation ditch simultaneously, waterproof effect is better; During construction, adopt digging machine adapted piling machinery hand as heavy establish the Larsen stake major impetus, it is fast to beat or pull out Larsen steel sheet pile speed, easy construction, fast.
Description of drawings
Fig. 1 is a kind of structural representation that is used for the Larsen steel sheet pile of foundation pit support construction;
Fig. 2 is along the cross section view of A-A direction among Fig. 1.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done explanation in further detail.
Like Fig. 1, shown in 2, a kind of Larsen steel sheet pile that is used for foundation pit support construction, comprise cross section be rectangular configuration steel plate enclosure wall body 1, be arranged on bracing frame and detachable connecting device 4 in this steel plate enclosure wall body.Bracing frame comprises transverse support bar 2 and oblique support bar 3, and transverse support bar 2 is supported on the middle part of corresponding both sides of the steel plate enclosure wall body 1 of rectangular configuration, is fixedly connected through the middle part of oblique support bar 3 with other both sides respectively on the both sides of this respective side.
Detachable connecting device 4 comprises channel-section steel limiting plate 41 that opening makes progress and the channel-section steel buckle 42 that Open Side Down.Channel-section steel limiting plate 41 is fixed on the steel plate enclosure wall body 1, and channel-section steel buckle 42 is combined on the channel-section steel limiting plate 41 through the bolt junction button, and the two ends of transverse support bar 2 and oblique support bar 3 are installed in respectively in the stopper slot of being made up of channel-section steel limiting plate 41 and channel-section steel buckle 42.
In the present embodiment, as enclosing purlin, transverse support bar 2 adopts welded tube with oblique support bar 3 with steel plate enclosure wall body 1.
During construction, adopt the digging machine adapted high frequency heavy major impetus of establishing the Larsen stake of hydraulic vibration piling machinery hand conduct by a narrow margin.Measurement confirms to go along with sb. to guard him the position at edge, hole, drives piles along the line, and is vertical down in principle.Enclose purlin in the inboard setting of cutting the earth of the steel sheet pile of accomplishing fluently, transverse support bar 2 requires stress equalization with oblique support bar 3, guarantees supporting safety.Purlin and support bar are enclosed in dismounting: in accomplishing foundation ditch behind civil engineering work to the ground matrix section, and backfilling compaction can be removed and enclose purlin and support bar after enclose the below.Pull out steel sheet pile and still adopt the digging machine of being furnished with fluid pressure type oscillating machinery hand, this machine seaming is tight, and the object of ton surplus 10 can tightly be stung, and the utilization high frequency is extricated oneself from a predicament and brace oneself up to action, and speed is fast, and band mud amount is few.In order to reduce influence to cushion cap basis 5, when pile pulling, take to pull out the mode repeatable operation that 1m returns 0.5m, like this, earth is taken out of lessly during pile pulling, and settlement influence is reduced to Min..
