Description

For reinforcing the pile frame structure of culvert

Technical field

The utility model relates to culvert construction technical fields, in particular to for reinforcing the pile frame structure of culvert.

Background technique

Currently, the infrastructure such as railway, highway and municipal administration are built energetically in China, correspondingly, Culvert engineering is also got over To be more widely applied to, there are in high roadbed and the highway in deep soft base location, High Speed Rail Projects.However due to previous It is inadequate to the understanding of special road section culvert, so often appearance is bigger than normal or less than normal to structure stress design consideration, as a result often Lead to engineering disease.From this, with the continuous social and economic development, being carried out under the culvert with high roadbed and deep soft base The case where stiffening basic ground, can be more and more.

It is small that small pile foundation influences disturbance to ambient enviroment and soil layer, when construction will not make surrounding soil disturb and intensity substantially It reduces, there is its unique application value.

In view of laying out pile in the culvert in-cavity construction of narrow space, reinforcement processing is carried out to soft foundation soil layer again, and Comprehensively consider various factors, is suitble to laying, consolidation effect under short steric requirements preferably small therefore, it is necessary to develop one kind Pile foundation.

Utility model content

The technical problem to be solved by the utility model is to provide the pile frame structures for reinforcing culvert, are applicable to short Spatial arrangement, and consolidation effect is good.

Used technical solution to solve above-mentioned technical problem:

For reinforcing the pile frame structure of culvert, including the pile element that several splice in length and breadth, each pile element includes putting The pile crown below culvert is set, is spliced between the adjacent pile element by footing, each footing is solid with the pile crown It is fixed, two footing composition " V " type structures mutually spliced.

Further, the quantity of footing described in each pile element is four, and the axis of four footings is respectively positioned on together The side of one circular cone, and the axis of each footing is parallel with the round element of a cone, the axis of each footing is uniform It is distributed in the side of the circular cone, the pile crown is located at the vertex of the circular cone.

Further, in two footings mutually spliced, one of them described footing includes plug-in type ledges, another The footing includes spigot-and-socket ledges.

Further, the plug-in type ledges include a short main reinforcement, two long main reinforcements, several equilateral triangle u stirrups and One "-" type stirrup.

Further, the spigot-and-socket ledges includes three long main reinforcements and several equilateral triangle u stirrups.

Further, an end embowment outward of each long main reinforcement, the end are far from the stake One end of head.

The utility model has the advantages that the utility model is the pile frame structure for the sustainable culvert being spliced by several pile elements, Stake holes has been dug on ground in advance, then can securely support culvert at the footing and pile crown of each pile element by concreting, prevent Culvert sinks.The utility model is simple and strong in structure, can be widely applied to culvert construction technical field.

Specific embodiment

The utility model is described further below with reference to Fig. 1 to Figure 15.

For reinforcing the pile frame structure of culvert, including the pile element that several splice in length and breadth, in the present embodiment, each stake Unit spliced is a rectangular pile frame structure.Each pile element includes the pile crown 1 being placed below culvert, and adjacent is described Spliced between pile element by footing, two footing composition " V " type structures mutually spliced.The length phase of each footing Together, each footing is fixed with the pile crown 1, and each footing is reinforced concrete structure.

The quantity of footing described in each pile element is four, and the axis of each footing is respectively positioned on the same circular cone Side, and the axis of each footing is parallel with the round element of a cone, the axis of each footing is evenly distributed on described The side of circular cone.The pile crown 1 is located at the vertex of the circular cone, in the present embodiment, one end of each footing with the stake First 1 lower end is fixed.The pile crown 1 is column structure, and the axis of the pile crown 1 is overlapped with the axis of the circular cone, and described The size of pile crown 1 is bigger than the drilling on culvert.In other embodiments, the pile crown 1 is also designed to the block of cuboid Shape structure.

In two footings mutually spliced, one of them described footing includes plug-in type ledges 4, another described stake Foot includes spigot-and-socket ledges 5, the plug-in type ledges 4 and spigot-and-socket ledges 5 with used when casting concrete in building field Reinforcement cage structure it is similar.Such as Figure 10, in the present embodiment, the pile element shares three types: corner pile frame 67, intermediate pile frame 68 With skirt piles frame 69.Such as Fig. 1,2 and 3, the quantity of the corner pile frame 67 is four, is located at four rectangular angles, each institute Two adjacent footings in corner pile frame 67 are stated to be used to splice with other pile elements, which can be considered splicing taper pile 2, The footing that other two is not used in splicing can be considered independent taper pile 3.Such as Fig. 4,5 and 6, each intermediate pile frame 68 is located at institute State rectangular inside, it is clear that four footings of the intermediate pile frame 68 are splicing taper pile 2.Such as Fig. 7,8 and 9, each skirt piles Frame 69 is located at four rectangular sides, therefore three footings are splicing taper pile 2 in the skirt piles frame 69, one remaining The footing is independent taper pile 3.It in other embodiments, can also be only by four corner piles if the rectangular area is smaller The splicing composition of frame 67.

In the present embodiment, the independent taper pile 3 can be made of 5 casting concrete of spigot-and-socket ledges, can also be by plug-in type 4 casting concrete of ledges is made.

Such as Figure 12 and 13, the spigot-and-socket ledges 5 includes three long main reinforcements and several equilateral triangle u stirrups.Such as Figure 14 With 15, the plug-in type ledges 4 includes a short main reinforcement, two long main reinforcements, several equilateral triangle u stirrups and a word Type stirrup, the both ends of the "-" type stirrup are fixed with the long main reinforcement respectively.The spigot-and-socket ledges 5 and plug-in type ledges 4 In, the interval of each equilateral triangle u stirrup is uniform, and the long main reinforcement and equilateral triangle u stirrup interior angle, the short main reinforcement It is to be fixed by way of welding or iron wire binding between equilateral triangle u stirrup interior angle.

Such as Figure 12 and 13, in the present embodiment, an end embowment outward of each long main reinforcement, and be bent Antirust treatment is done at place, and the end is one end far from the pile crown 1.When the plug-in type ledges 4 and the spigot-and-socket muscle Two long main reinforcements hook corresponding with the two long main reinforcement in the spigot-and-socket ledges 5 when frame 5 splices, in the plug-in type ledges 4 Firmly.In addition, the length difference between the long main reinforcement and the short main reinforcement in the plug-in type ledges 4 caused by space just may be used It is passed through for the long main reinforcement of third in the spigot-and-socket ledges 5, i.e., is yin-yang between the described plug-in type ledges 4 and spigot-and-socket ledges 5 Connecting method.

Method using the utility model support culvert is as follows:

The stake holes of each footing of correspondence first has been dug on ground, then each plug-in type ledges and spigot-and-socket ledges have successively been spelled It connects and is fixed in each stake holes, then casting concrete produces footing and pile crown.

The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to State embodiment, within the scope of knowledge possessed by those of ordinary skill in the art, can also do not depart from it is practical Various changes can be made under the premise of novel objective.
