Abstract
The utility model discloses a steel sheet pile underground structure, including the front -seat steel sheet pile that is used for the foundation ditch stagnant water, be used for the earth -retaining H shaped steel of foundation ditch, be used for supplementary stagnant water and earth -retaining back row steel sheet pile, the steel sheet -pile structure of front -seat steel sheet pile and back row steel sheet pile is the same, and both ends all are equipped with the hasp, H shaped steel is by web and both wings board are constituteed always, the both ends of pterygoid lamina are equipped with hasp cooperation portion, straight web is located the wrong face down bonding in both ends and has met two seamless steel pipe, and seamless steel pipe's upper end is connected with supplementary water jetting at high pressure subassembly, and the lower extreme is connected with the nozzle mouth. The utility model discloses it is rational in infrastructure, through insert H shaped steel in the steel sheet pile, improved structural stiffness to be applicable to excavation depth than the deep basal pit, be connected with the seamless steel pipe of supplementary water jetting at high pressure subassembly simultaneously through the setting, reduce the rigid damage of H shaped steel unnecessary.
Description
Technical field
This utility model relates to Base hole supporting technology field, particularly relates to a kind of steel sheet piling pit supporting construction.
Background technology
Steel sheet pile is a kind of belt lock catch or the hot rolling of jaw or cold-rolled forming section, is connected with each other occlusion by snap close or jaw after squeezing into, and forms continuous print steel sheet pile enclosure wall, is used for keeping off soil and dash.The features such as it has quick construction, and foundation pit construction terminates rear steel sheet pile and can pull out, and recycles, better economy, are widely used in a variety of applications in the industry such as water conservancy, traffic.But owing to steel sheet pile anti-side rigidity is relatively small, deform bigger.Surrounding enviroment require higher and dig deeply the biggest base pit engineering is applied less.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, it is provided that a kind of rigidity of structure is big, be applicable to the cutting depth steel sheet piling pit supporting construction compared with deep basal pit.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions:
A kind of steel sheet piling pit supporting construction, including for foundation ditch sealing front-seat steel sheet pile, for foundation ditch gear soil H profile steel, for assist sealing and gear soil heel row steel sheet pile, the steel sheet pile structure of described front-seat steel sheet pile and heel row steel sheet pile is identical, two ends are equipped with snap close, described H profile steel is made up of web always and two wing plates, the two ends of described wing plate are provided with snap fit portion, described straight web is positioned at mistake side, two ends and is welded with two seamless steel pipes, and the upper end connection of seamless steel pipe has additional high pressure jetting assembly, lower end connects jet hole.
Further, described front-seat steel sheet pile and heel row steel sheet pile are U-shaped steel sheet pile.
The beneficial effects of the utility model are:
This utility model is rational in infrastructure, by accessing H profile steel in steel sheet pile, improves the rigidity of structure, thus is applicable to cutting depth relatively deep basal pit；There is the seamless steel pipe of additional high pressure jetting assembly simultaneously by arranging connection, reduce the rigid damage that H profile steel is unnecessary.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, this utility model is described in detail.
A kind of steel sheet piling pit supporting construction described in the present embodiment, as shown in Figure 1, including the front-seat steel sheet pile 2 for foundation ditch sealing, H profile steel 4 for foundation ditch gear soil, for assisting sealing and the heel row steel sheet pile 5 of gear soil, the steel sheet pile structure of described front-seat steel sheet pile 2 and heel row steel sheet pile 5 is identical, two ends are equipped with snap close 1, described H profile steel 4 is made up of web always and two wing plates, the two ends of described wing plate are provided with snap fit portion 3, described straight web is positioned at mistake side, two ends and is welded with two seamless steel pipes 6, and the upper end connection of seamless steel pipe 6 has additional high pressure jetting assembly, lower end connects jet hole.
Further, described front-seat steel sheet pile 2 and heel row steel sheet pile 5 are U-shaped steel sheet pile.
Operation principle in the present embodiment is:
The snap fit portion 3 at H profile steel 4 one wing plate two ends and the mutual snapping of snap close 1 of front row steel sheet pile 2, the snap fit portion 3 at another wing plate two ends and the mutual snapping of snap close 1 of front row steel sheet pile 5, additional high pressure jetting assembly is utilized to carry out high-pressure water delivery supply, at the jet hole of seamless steel pipe 6, strength injection pours hard ground, coordinate vibration hammer again, H profile steel 4 of just can sinking smoothly.
