The utility model discloses the simple compactness of mechanism, low in production cost, through will protecting during a section of thick bamboo goes a hole, form the similar sheathed tube dado body in solution cavity mouth bottom to the stake hole pore wall between the top, place steel reinforcement cage and irrigation concrete again, prevent to run off from the solution cavity mouth pouring into the in -process concrete, guarantee to become a quality, it is shorter to protect the tube length degree simultaneously, selects the corresponding section of thick bamboo that protects according to solution cavity actual size, has practiced thrift the material, and the height that protects a section of thick bamboo that shortens has also made things convenient for the transportation.
Description
Technical field
The utility model relates to technical field of building construction, more particularly, particularly relates to a kind of solution cavity district sleeve filling pile for solution cavity geology.
Background technology
In the process of building operations, normally utilize punching pile machine on the ground impact place one there is the stake holes of the larger degree of depth, then in stake holes, sink to castinplace pile, placing of concrete in last Reperfu-sion stake, form the bottom foundation pile of building.Due to friction when castinplace pile has a construction, little without soil compaction, noise, be suitable in advantages such as City Building City Regions uses, be therefore widely used in work progress.
Existing castinplace pile is normally indulged muscle by multiple main cage and is looped around multiple stirrups that main cage indulges muscle periphery and forms, when solution cavity geology is constructed, stake holes can be circulated into solution cavity inside usually, because solution cavity is communicated with stake holes, when concrete perfusion, a large amount of concrete can flow out from castinplace pile side, and enter solution cavity inside from the connectivity part of stake holes and solution cavity, and solution cavity inside has larger space usually, therefore, the concrete of flow-like can enter into inner and existing solid by solution cavity in solution cavity district, just can arrive the top of stake holes afterwards, that is existing castinplace pile can slattern a large amount of concrete usually when solution cavity geological province is constructed, namely to surpass filling amount large for concrete, fullness coefficient is high, therefore result in construction costs higher.
Existing three kinds are mainly contained to the method that solution cavity geology carries out filling pile construction, the first is when disclosing solution cavity in pore forming process, in solution cavity, fill block stone or clay bag, then proceed pore-forming operation until projected depth, last below reinforcing cage and fluid concrete.Due to solution cavity out-of-shape and filling leakiness, filler is difficult to solution cavity to fill up completely tamp, and concrete easily runs off from large space, and under concrete side pressure effect, the hole wall that filler is formed easily subsides, and causes pile difficulty.
Second method wraps up one deck iron clad skin in reinforcing cage surrounding, and this method cost is low, simple to operate, but owing to there being larger gap between iron sheet and hole wall, concrete cannot be filled into, this section of pile body sidewall friction resistance is lost, and stake footpath diminishes simultaneously, causes the bearing capacity of stake to reduce.
Utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, a kind of solution cavity district sleeve filling pile is provided, by by under casing in stake holes, form the retaining wall body of similar sleeve pipe to the stake holes hole wall between top bottom solution cavity mouth, place reinforcing cage and concrete perfusion again, prevent concrete in filling process to run off from solution cavity mouth, guarantee pile quality.
The technical solution of the utility model is achieved in that solution cavity district sleeve filling pile, comprise many main cages to indulge muscle and be fixed on the stirrup that muscle outside indulged by many main cages, it is characterized in that, this castinplace pile also comprises and is positioned at the casing that muscle outside indulged by main cage, this casing is sleeved on the periphery that muscle indulged by main cage, and the bottom of casing is provided with the support portion of the axial level with casing.
Further, described stirrup comprises two spiral stirrups and multiple ring-type stirrup, and two spiral stirrups are separately fixed at the upper and lower end that muscle indulged by many main cages, and multiple ring-type stirrup is arranged between two spiral stirrups.
Further, described casing is made up of steel material.
Further, the thickness of described casing is 10-20mm.
Further, described support portion is reinforcing bar.
Further, top, described support portion is provided with screw thread, is provided with screwed hole bottom casing, the adjustment of the fixing and support portion length of position both being realized by threaded engagement bottom support portion and casing.
Further, described support portion is provided with and multiplely distributes along casing bottom even.
Technical thought of the present utility model is: by by under casing in stake holes, form the retaining wall body of similar sleeve pipe to the stake holes hole wall between top bottom solution cavity mouth, place reinforcing cage and concrete perfusion again, prevent concrete in filling process to run off from solution cavity mouth, guarantee pile quality; Casing is steel pile casting, and have length not wait multiple, select corresponding casing according to the height of actual solution cavity; By coordinating of casing and support portion reinforcing bar, realize the fixing of casing position, ensure that casing is fixed on between top bottom solution cavity mouth, passable up and down; Leave certain surplus, prevent that excessive gap causes concrete to spill from gap.
The beneficial effects of the utility model are: the utility model mechanism is simply compact, and cost of production is low; By by under casing in stake holes, bottom solution cavity mouth, form the retaining wall body of similar sleeve pipe to the stake holes hole wall between top, then place reinforcing cage and concrete perfusion, prevent concrete in filling process to run off from solution cavity mouth, guarantee pile quality; Casing length is shorter simultaneously, and select corresponding casing according to solution cavity real size, saved material, the height of the casing of shortening, also facilitates transport.
