Abstract
The invention belongs to the field of foundation pit supporting and underground engineering, and provides a pile and wall integrated structure combining an outer wall of a basement body and a guard pile. According to the technical scheme, a narrow space is formed between the outer wall of a basement and the guard pile, in the space, a net-hanging guniting layer, a thermal insulation layer and a flexible waterproof layer are sequentially bonded to the side face of the outer wall of the basement, a force transmission plate strip is arranged on the outer side of the outer wall of the basement, the force transmission plate strip is horizontally arranged at the position of each floor of the basement, the force transmission plate strip is perpendicular to the outer wall of the basement and horizontally inserted into the surface of the net-hanging guniting layer, a foundation slab extends to the surface of the net-hanging guniting layer, the thermal insulation layer is broken at the position where the force transmission plate strip makes contact with the foundation slab, and the flexible waterproof layer continues at the position where the force transmission plate belt makes contact with the foundation slab. According to the pile and wall integrated structure, combined action of the guard pile and the outer wall of the basement at the permanent use stage is achieved, the thickness of the outer wall of the underground structure can be reduced after consideration is given to the rigidity of the guard pile, therefore, engineering investment is saved, and resources are used reasonably.
Description
Technical field
The invention belongs to a part of utilizing bracing of foundation pit stake acting in conjunction the permanent operational phase sidewall of basement soil-baffling structure of conduct in fixed buildings pattern foundation pit supporting structure and underground engineering field, consider node and the structure of the mixture of piles and concrete wall that bracing of foundation pit stake combines with outer wall of basement, can be widely used in adopting in the pattern foundation pit supporting structure and underground construction of castinplace pile campshed.
Background technology
Along with the development of modern city, the exploitation of the urban underground space development trend that become international, and become the important symbol of weighing urban modernization.Pattern foundation pit supporting structure is an important project content in underground space development, also relates to the soil body, supporting and protection structure, the coefficient problem of underground structure in having the base pit engineering of retaining structure.Castinplace pile campshed support technology is as a kind of engineering method of maturation, and simple, the easy to control the quality system of its construction technology is little on surrounding enviroment impact during construction, is widely used in base pit engineering.Yet at present castinplace pile campshed is generally only as temporary support structures, after base pit engineering completes, give no thought to its effect and abandoned in underground.Between conventional bracing of foundation pit stake and outer wall of basement, leave certain spacing, be beneficial to the formwork of outer wall of basement and assembling reinforcement, waterproof thermal-insulated construction, outer wall of basement respectively according to permanent stage and construction pit excavation different operating mode Force Calculation of stage, is not considered acting in conjunction with fender post.The present invention considers that bracing of foundation pit stake and outer wall of basement combine, consider that interim castinplace pile campshed is as a part for permanent operational phase sidewall of basement soil-baffling structure, adopt mixture of piles and concrete wall technology, a part using original discarded interim fender post as permanent outer wall of basement, reduce the thickness of outer wall of basement, save construction costs, be with a wide range of applications.
Summary of the invention
Technical problem to be solved by this invention has been to provide a kind of consideration and has utilized bracing of foundation pit stake as the mixture of piles and concrete wallization structure of a permanent operational phase sidewall of basement soil-baffling structure part, avoided conventional base pit engineering to implement the campshed of going along with sb. to guard him of rear completely discarded periphery, still needed simultaneously and will meet basement in building function requirements such as the waterproof of permanent operational phase, insulations.
For solving the problems of the technologies described above, technical scheme of the present invention is: between outer wall of basement and fender post, form narrow space, in described space, shotcrete with steel bar nets layer is successively sticked along described outer wall of basement side, insulation layer, flexible waterproof layer, and in described outer wall of basement arranged outside power transmission strip, the horizontal level of described power transmission strip is each floor Board position place of basement, and vertical with described outer wall of basement, level is inserted into described shotcrete with steel bar nets layer surface, sole plate extends to described shotcrete with steel bar nets layer surface, described insulation layer disconnects with described load transfering strip and described sole plate contact position place, described flexible waterproof layer is continuous with described load transfering strip and described sole plate contact position place.
Basic conception of the present invention is: be different from reserved at least operating space more than 800mm between conventional fender post and outer wall of basement, fender post and outer wall of basement are close to construction substantially, therebetween shotcrete with steel bar nets, the construction space of insulation layer and flexible waterproof layer, excavation of foundation pit to after substrate after the shotcrete with steel bar nets levelling of fender post surface single side formwork construction outer wall of basement again after construction heat-insulating layer and flexible waterproof layer, because intermediate course (insulation layer) is relatively soft interlayer, therefore consider, at each floor Board position of basement, rigidity power transmission strip is set between outer wall of basement and fender post, insulation layer disconnects and primarily meets the power transmission requirement between fender post and outer wall of basement in load transfering strip position.The material of insulation layer and flexible waterproof layer can need in conjunction with the function of building to choose according to corresponding code requirement.Between fender post and outer wall of basement except arranging power transmission strip at each floor position of basement, the still need space of insulation layer and flexible waterproof layer between reserved piling wall, all the other positions, the space that simultaneously needs reserved certain construction deviation and space enclosing structure distortion, concrete reserved size is chosen according to project situation and construction equipment precision.
The use of the mixture of piles and concrete wallization structure combining with fender post due to aforementioned body outer wall of basement, fender post and outer wall of basement have been realized in the acting in conjunction of permanent operational phase, considered after the stiffness contribution of fender post can attenuate outer wall of basement thickness, cost saving, makes rational use of resources.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example and application construction method, the invention will be further described.
Fig. 1 is the nodal plane figure of patent of the present invention.
Fig. 2 is the fender post surface shotcrete with steel bar nets constructional drawing of patent of the present invention.
